I ve struggled with this one for a long time and I wanted to share my solution   This will give you a UILabel that will autoshrink text down to 0 5 scales and vertically center the text  These options are also available in Storyboard IB    labelObject setMinimumScaleFactor 0 5    labelObject setBaselineAdjustment UIBaselineAdjustmentAlignCenters

Subclass UILabel and constrain the drawing rectangle  like this   -  void drawTextInRect  CGRect rect       CGSize sizeThatFits    self sizeThatFits rect size       rect size height   MIN rect size height  sizeThatFits height         super drawTextInRect rect       I tried the solution involving newline padding and ran into incorrect behavior in some cases  In my experience  it s easier to constrain the drawing rect as above than mess with numberOfLines   P S  You can imagine easily supporting UIViewContentMode this way   -  void drawTextInRect  CGRect rect       CGSize sizeThatFits    self sizeThatFits rect size        if  self contentMode    UIViewContentModeTop            rect size height   MIN rect size height  sizeThatFits height             else if  self contentMode    UIViewContentModeBottom            rect origin y   MAX 0  rect size height - sizeThatFits height           rect size height   MIN rect size height  sizeThatFits height               super drawTextInRect rect

This code helps you to make the text aligned to top and also to make the label height to be fixed the text content   instruction to use the below code  isHeightToChange by default it is true makes the height of label to same as text content automatically  isHeightToChange if it false make the text aligned to top with out decreasing the height of the label    import  DynamicHeightLable h    implementation DynamicHeightLable  synthesize isHeightToChange  -  id initWithFrame  CGRect frame        self    super initWithFrame frame       if  self                   Initialization code          self isHeightToChange FALSE   default            return self    -  void drawTextInRect  CGRect rect       if  isHeightToChange       CGSize maximumLabelSize   CGSizeMake self frame size width 2500        CGFloat height    self text sizeWithFont self font                            constrainedToSize maximumLabelSize                                lineBreakMode self lineBreakMode  height      if  self numberOfLines    0            height   MIN height  self font lineHeight   self numberOfLines             rect size height   MIN rect size height  height              super drawTextInRect rect      -  void  layoutSubviews        super layoutSubviews          if isHeightToChange        CGRect ltempFrame   self frame      CGSize maximumLabelSize   CGSizeMake self frame size width 2500        CGFloat height    self text sizeWithFont self font                            constrainedToSize maximumLabelSize                                lineBreakMode self lineBreakMode  height      if  self numberOfLines    0            height   MIN height  self font lineHeight   self numberOfLines             ltempFrame size height   MIN ltempFrame size height  height        ltempFrame size height ltempFrame size height      self frame ltempFrame              end

As long as you are not doing any complex task  you can use UITextView instead of UILabels   Disable the scroll   If you want the text to be displayed completely just user sizeToFit and sizeThatFits  methods

I was working on that particular problem as well  so I ve taken the ideas by D S  and nevan king and basically combined them into a subclass that implements a vertical alignment property  which also allows you to change the alignment more than just once  It borrows the UIControlContentVerticalAlignment type and also supports UIControlContentVerticalAlignmentFill   From what I ve seen  numberOfLines seems to be useless when it comes to vertical alignment  so in this subclass it is always set to 0 when applying vertical alignment  Also  you still have to set lineBreakMode yourself in case you want a multi-line text label   There it is  QALabel on GitHub

Just in case it s of any help to anyone  I had the same problem but was able to solve the issue simply by switching from using UILabel to using UITextView  I appreciate this isn t for everyone because the functionality is a bit different   If you do switch to using UITextView  you can turn off all the Scroll View properties as well as User Interaction Enabled    This will force it to act more like a label

I ve found the answers on this question are now a bit out-of-date  so adding this for the auto layout fans out there   Auto layout makes this issue pretty trivial  Assuming we re adding the label to UIView  view  the following code will accomplish this   UILabel  label     UILabel alloc  initWithFrame CGRectZero    label setText   Some text here     label setTranslatesAutoresizingMaskIntoConstraints NO    view addSubview label     view addConstraints  NSLayoutConstraint constraintsWithVisualFormat   H   label    options 0 metrics nil views     label   label      view addConstraints  NSLayoutConstraint constraintsWithVisualFormat   V   label   options 0 metrics nil views     label   label       The label s height will be calculated automatically  using it s intrinsicContentSize  and the label will be positioned edge-to-edge horizontally  at the top of the view

There s no way to set the vertical-align on a UILabel  but you can get the same effect by changing the label s frame  I ve made my labels orange so you can see clearly what s happening   Here s the quick and easy way to do this        myLabel sizeToFit         If you have a label with longer text that will make more than one line  set numberOfLines to 0  zero here means an unlimited number of lines        myLabel numberOfLines   0       myLabel sizeToFit         Longer Version  I ll make my label in code so that you can see what s going on  You can set up most of this in Interface Builder too  My setup is a View-Based App with a background image I made in Photoshop to show margins  20 points   The label is an attractive orange color so you can see what s going on with the dimensions   -  void viewDidLoad        super viewDidLoad           20 point top and left margin  Sized to leave 20 pt at right      CGRect labelFrame   CGRectMake 20  20  280  150       UILabel  myLabel     UILabel alloc  initWithFrame labelFrame        myLabel setBackgroundColor  UIColor orangeColor         NSString  labelText     I am the very model of a modern Major-General  I ve information vegetable  animal  and mineral        myLabel setText labelText           Tell the label to use an unlimited number of lines      myLabel setNumberOfLines 0        myLabel sizeToFit         self view addSubview myLabel       Some limitations of using sizeToFit come into play with center- or right-aligned text  Here s what happens          myLabel textAlignment   NSTextAlignmentRight      myLabel textAlignment   NSTextAlignmentCenter        myLabel setNumberOfLines 0        myLabel sizeToFit       The label is still sized with a fixed top-left corner  You can save the original label s width in a variable and set it after sizeToFit  or give it a fixed width to counter these problems       myLabel textAlignment   NSTextAlignmentCenter        myLabel setNumberOfLines 0        myLabel sizeToFit        CGRect myFrame   myLabel frame         Resize the frame s width to 280  320 - margins         width could also be myOriginalLabelFrame size width     myFrame   CGRectMake myFrame origin x  myFrame origin y  280  myFrame size height       myLabel frame   myFrame        Note that sizeToFit will respect your initial label s minimum width  If you start with a label 100 wide and call sizeToFit on it  it will give you back a  possibly very tall  label with 100  or a little less  width  You might want to set your label to the minimum width you want before resizing     Some other things to note   Whether lineBreakMode is respected depends on how it s set  NSLineBreakByTruncatingTail  the default  is ignored after sizeToFit  as are the other two truncation modes  head and middle   NSLineBreakByClipping is also ignored  NSLineBreakByCharWrapping works as usual  The frame width is still narrowed to fit to the rightmost letter     Mark Amery gave a fix for NIBs and Storyboards using Auto Layout in the comments      If your label is included in a nib or storyboard as a subview of the view of a ViewController that uses autolayout  then putting your sizeToFit call into viewDidLoad won t work  because autolayout sizes and positions the subviews after viewDidLoad is called and will immediately undo the effects of your sizeToFit call  However  calling sizeToFit from within viewDidLayoutSubviews will work     My Original Answer  for posterity reference    This uses the NSString method sizeWithFont constrainedToSize lineBreakMode  to calculate the frame height needed to fit a string  then sets the origin and width   Resize the frame for the label using the text you want to insert  That way you can accommodate any number of lines   CGSize maximumSize   CGSizeMake 300  9999   NSString  dateString     The date today is January 1st  1999   UIFont  dateFont    UIFont fontWithName   Helvetica  size 14   CGSize dateStringSize    dateString sizeWithFont dateFont          constrainedToSize maximumSize          lineBreakMode self dateLabel lineBreakMode    CGRect dateFrame   CGRectMake 10  10  300  dateStringSize height    self dateLabel frame   dateFrame

Instead of using sizeToFit  you could manually change the label s height   CGSize size    descLabel text sizeWithFont descLabel font constrainedToSize CGSizeMake labelWidth  labelHeight    CGRect frame   descLabel frame  frame size height   size height       yourLabel setFrame frame     The size returned will be the best fit for the content of your label  If the label s height is fitted to its content  you wouldn t have problems with the content being positioned on the center of the label

An even quicker  and dirtier  way to accomplish this is by setting the UILabel s line break mode to  Clip  and adding a fixed amount of newlines   myLabel lineBreakMode   UILineBreakModeClip  myLabel text    displayString stringByAppendingString   n n n n      This solution won t work for everyone -- in particular  if you still want to show       at the end of your string if it exceeds the number of lines you re showing  you ll need to use one of the longer bits of code -- but for a lot of cases this ll get you what you need

Simple solution to this problem      Place a UIStackView bellow the label    Then use AutoLayout to set a vertical spacing of zero to the label and constraint the top to what was previously the bottom of the label  The label won t grow  the stackView will  What I like about this is that the stack view is non rendering  So it s not really wasting time rendering  Even though it makes AutoLayout calculations   You probably will need to play with ContentHugging and Resistance though but that s simple as well    Every now and then I google this problem and come back here  This time I had an ideia that I think is the easiest  and I don t think it s bad performance wise   I must say that I m just using AutoLayout and don t really want to bother calculating frames  That s just    yuck

If you are using autolayout  set the vertical contentHuggingPriority to 1000  either in code or IB  In IB you may then have to remove a height constraint by setting it s priority to 1 and then deleting it

I know this is an old post but vertically aligning text is a HUGE problem  at least for me it is  and I figured that I should share this solution since I couldn t find one myself    Using drawRect is a little expensive in my opinion  The proper way to get a UILabel to vertically align is to not use a UILabel  Use a UITextView  multiline UITextField  and observe the content property like so   -  UITextView  textView       if   textView           UIEdgeInsets insets   UIEdgeInsetsMake 0  50  0  5           CGRect frame   CGRectMake 0 0f  0 0f  100 0f  100 0f            textView     UITextView alloc initWithFrame UIEdgeInsetsInsetRect frame  insets             textView delegate   self           textView scrollEnabled   YES           textView bounces   YES           textView backgroundColor    UIColor whiteColor             textView setUserInteractionEnabled NO             textView addObserver self forKeyPath   contentSize  options  NSKeyValueObservingOptionNew  context NULL             return  textView      - void observeValueForKeyPath  NSString   keyPath ofObject  id object change      NSDictionary   change context  void   context   UITextView  tv   object   CGFloat height    tv bounds  size height  CGFloat contentheight    ifdef   IPHONE 7 0     contentheight    tv sizeThatFits CGSizeMake tv frame size width  FLT MAX   height   else     contentheight    tv contentSize  height   endif      switch self verticalAlignment            case VerticalAlignmentBottom               CGFloat topCorrect     tv bounds  size height - contentheight               topCorrect    topCorrect  lt 0 0   0 0   topCorrect               tv contentOffset    CGPoint   x   0   y   -topCorrect                     break          case VerticalAlignmentMiddle               CGFloat topCorrect    height - contentheight    tv zoomScale   2 0              topCorrect     topCorrect  lt  0 0   0 0   topCorrect                tv contentOffset    CGPoint   x   0   y   -topCorrect                         break          case VerticalAlignmentTop               tv contentOffset    CGPoint   x   0   y   0                          break          default              break            Basically what s happening here is we set the class we re in as the observer  looking at the contentSize property with an option of NSKeyValueObservingOptionNew so every time the content changes  - void observeValueForKeyPath ofObject change context  will get called and then you can calculate an offset size to align the text appropriately    I can t take credit for this  the original idea came from here  But  this solution doesn t work on iOS7  After trolling around SO for a few hours  I found this  iOS 7 vertical alignment fix  The key line there is contentheight    tv sizeThatFits CGSizeMake tv frame size width  FLT MAX   height   For some reason in iOS 7  getting the contentSize height doesn t work but that fixes it  Neither of the two solutions worked on their own but after a little tinkering  I was able to synthesize together the above solution

There are two ways to fix this problem One is   mylabel setNumberOfLines 0    mylabel sizeToFit     But the second way is more reliable for this approach  i e    CGSize sizeToFit    label text sizeWithFont label font constrainedToSize maxSize lineBreakMode label lineBreakMode     mylabel setFrame CGRectMake mylabel frame origin x  mylabel frame origin y  sizeToFit width  sizeToFit height      entering   n  is not such a good thing but yes if you know the constraints and the size of the data going to be displayed  may be it work good but cannot be expandable if text is longer than size of the label  The Second way ultimately set the frame according to the size of the text going to be displayed

In UILabel vertically text alignment is not possible  But  you can dynamically change the height of the label using sizeWithFont  method of NSString  and just set its x and y as you want   You can use UITextField  It supports the contentVerticalAlignment peoperty as it is a subclass of UIControl  You have to set its userInteractionEnabled to NO to prevent user from typing text on it

It can be done with more flexibility setting a height constraint to the label in Interface Builder  binding it to the code with an IBOutlet and changing that height to show the text in a concrete vertical position  Example for center and bottom alignment   labelHeightConstraint constant   centerAlignment   30   15 layoutIfNeeded

I took a while to read the code  as well as the code in the introduced page  and found that they all try to modify the frame size of label  so that the default center vertical alignment would not appear   However  in some cases we do want the label to occupy all those spaces  even if the label does have so much text  e g  multiple rows with equal height    Here  I used an alternative way to solve it  by simply pad newlines to the end of label  pls note that I actually inherited the UILabel  but it is not necessary    CGSize fontSize    self text sizeWithFont self font    finalHeight   fontSize height   self numberOfLines  finalWidth   size width       expected width of label  CGSize theStringSize    self text sizeWithFont self font constrainedToSize CGSizeMake finalWidth  finalHeight  lineBreakMode self lineBreakMode    int newLinesToPad    finalHeight  - theStringSize height    fontSize height   for int i   0  i  lt  newLinesToPad  i          self text    self text stringByAppendingString    n

for anyone reading this because the text inside your label is not vertically centered  keep in mind that some font types are not designed equally  for example  if you create a label with zapfino size 16  you will see the text is not perfectly centered vertically   however  working with helvetica will vertically center your text

Refering to the extension solution   for int i 1  i lt  newLinesToPad  i         self text    self text stringByAppendingString    n      should be replaced by   for int i 0  i lt newLinesToPad  i        self text    self text stringByAppendingString    n       Additional space is needed in every added newline  because iPhone UILabels  trailing carriage returns seems to be ignored     Similarly  alignBottom should be updated too with a     n    in place of   n     for cycle initialization must be replaced by  for int i 0     too    The following extension works for me      -- file  UILabel VerticalAlign h  pragma mark VerticalAlign  interface UILabel  VerticalAlign  -  void alignTop  -  void alignBottom   end     -- file  UILabel VerticalAlign m  implementation UILabel  VerticalAlign  -  void alignTop       CGSize fontSize    self text sizeWithFont self font       double finalHeight   fontSize height   self numberOfLines      double finalWidth   self frame size width       expected width of label     CGSize theStringSize    self text sizeWithFont self font constrainedToSize CGSizeMake finalWidth  finalHeight  lineBreakMode self lineBreakMode       int newLinesToPad    finalHeight  - theStringSize height    fontSize height      for int i 0  i lt newLinesToPad  i            self text    self text stringByAppendingString    n        -  void alignBottom       CGSize fontSize    self text sizeWithFont self font       double finalHeight   fontSize height   self numberOfLines      double finalWidth   self frame size width       expected width of label     CGSize theStringSize    self text sizeWithFont self font constrainedToSize CGSizeMake finalWidth  finalHeight  lineBreakMode self lineBreakMode       int newLinesToPad    finalHeight  - theStringSize height    fontSize height      for int i 0  i lt newLinesToPad  i            self text    NSString stringWithFormat     n    self text      end   Then call  yourLabel alignTop   or  yourLabel alignBottom   after each yourLabel text assignment
