How to set top-left alignment for UILabel for iOS application

Question

I have added one label in my nib file  then its required to have top-left alignment for that lable  As I am providing text at runtime so its not sure that how much lines there are  So if text contains only single line then it appears as vertical-center aligned  That alignment is not matching with my respective lable in front of it   For example     Which is looking odd     Is there any way where i can set label text proper to Top-Left alignment

In my case  it was bottom space constraint issue  I had set it to   16   When I set it to bottom to  gt   16  this issue got solved   Also  if you have any height constraint in the label  then you need to remove it   Here s my label s constraint view in the size inspector

The simplest and easiest way is to embed Label in StackView and setting StackView s Axis to  Horizontal  Alignment to Top in Attribute Inspector from Storyboard like shown here

User · Answer

you can also just change your UILabel to UITextView  because they basically do the same thing except the advantage of UITextView is that text is automatically aligned to the top left

I have this problem to but my label was in UITableViewCell  and in fund that the easiest way to solve the problem was to create an empty UIView and set the label inside it with constraints to the top and to the left side only  on off curse set the number of lines to 0

Building on top of totiG s awesome answer  I have created an IBDesignable class that makes it extremely easy to customize a UILabel s vertical alignment right from the StoryBoard  Just make sure that you set your UILabel s class to  VerticalAlignLabel  from the StoryBoard identity inspector  If the vertical alignment doesn t take effect  go to Editor- Refresh All Views which should do the trick    How it works  Once you set your UILabel s class correctly  the storyboard should show you an input field that takes an integer  alignment code    Update  I ve added support for centered labels  Sev    Enter 0 for Top Alignment  Enter 1 for Middle Alignment  Enter 2 for Bottom Alignment   x000D   x000D       IBDesignable class VerticalAlignLabel  UILabel   x000D       x000D       IBInspectable var alignmentCode  Int   0   x000D          didSet   x000D              applyAlignmentCode   x000D            x000D        x000D       x000D      func applyAlignmentCode     x000D          switch alignmentCode   x000D          case 0  x000D              verticalAlignment    top x000D          case 1  x000D              verticalAlignment    topcenter x000D          case 2  x000D              verticalAlignment    middle x000D          case 3  x000D              verticalAlignment    bottom x000D          default  x000D              break x000D            x000D        x000D       x000D      override func awakeFromNib     x000D          super awakeFromNib   x000D          self applyAlignmentCode   x000D        x000D       x000D      override func prepareForInterfaceBuilder     x000D          super prepareForInterfaceBuilder   x000D           x000D          self applyAlignmentCode   x000D        x000D       x000D      enum VerticalAlignment   x000D          case top x000D          case topcenter x000D          case middle x000D          case bottom x000D        x000D       x000D      var verticalAlignment   VerticalAlignment    top   x000D          didSet   x000D              setNeedsDisplay   x000D            x000D        x000D       x000D      override public func textRect forBounds bounds  CGRect  limitedToNumberOfLines  Int  - gt  CGRect   x000D          let rect   super textRect forBounds  bounds  limitedToNumberOfLines  limitedToNumberOfLines  x000D           x000D          if  available iOS 9 0       x000D              if UIView userInterfaceLayoutDirection for   unspecified      rightToLeft   x000D                  switch verticalAlignment   x000D                  case  top  x000D                      return CGRect x  self bounds size width - rect size width  y  bounds origin y  width  rect size width  height  rect size height  x000D                  case  topcenter  x000D                      return CGRect x  self bounds size width -  rect size width   2   y  bounds origin y  width  rect size width  height  rect size height  x000D                  case  middle  x000D                      return CGRect x  self bounds size width - rect size width  y  bounds origin y    bounds size height - rect size height    2  width  rect size width  height  rect size height  x000D                  case  bottom  x000D                      return CGRect x  self bounds size width - rect size width  y  bounds origin y    bounds size height - rect size height   width  rect size width  height  rect size height  x000D                    x000D                else   x000D                  switch verticalAlignment   x000D                  case  top  x000D                      return CGRect x  bounds origin x  y  bounds origin y  width  rect size width  height  rect size height  x000D                  case  topcenter  x000D                      return CGRect x   self bounds size width   2   -  rect size width   2   y  bounds origin y  width  rect size width  height  rect size height  x000D                  case  middle  x000D                      return CGRect x  bounds origin x  y  bounds origin y    bounds size height - rect size height    2  width  rect size width  height  rect size height  x000D                  case  bottom  x000D                      return CGRect x  bounds origin x  y  bounds origin y    bounds size height - rect size height   width  rect size width  height  rect size height  x000D                    x000D                x000D            else   x000D                 Fallback on earlier versions x000D              return rect x000D            x000D        x000D       x000D      override public func drawText in rect  CGRect    x000D          let r   self textRect forBounds  rect  limitedToNumberOfLines  self numberOfLines  x000D          super drawText in  r  x000D        x000D    x000D   x000D   x000D

As you are using the interface builder  set the constraints for your label  be sure to set the height and width as well   Then in the Size Inspector  check the height for the label  There you will want it to read    instead of    Then in the implementation for that view controller  set the number of lines to 0  can also be done in IB  and set the label  label sizeToFit   and as your text gains length  the label will grow in height and keep your text in the upper left

I was also having this problem but what I found was the the order in which you set the UILabel s properties and methods matters   If you call  label sizeToFit  before label font    UIFont fontWithName   Helvetica  size 14   then the text does not align to the top but if you swap them around then it does   I also noticed that setting the text first makes a difference too   Hope this helps

Rather than re-explaining  I will link to this rather extensive  amp  highly rated question answer   Vertically align text to top within a UILabel  The short answer is no  Apple didn t make this easy  but it is possible by changing the frame size

If what you need is non-editable text that by default starts at the top left corner you can simply use a Text View instead of a label and then set its state to non-editable  like this   textview isEditable   false   Way easier than messing with the labels     Cheers

In your code  label text     some text    label sizeToFit     Beware that if you use that in table cells or other views that get recycled with different data  you ll need to store the original frame somewhere and reset it before calling sizeToFit
