How to add line break for UILabel

Question

Let see that I have a string look like this      NSString  longStr     AAAAA nBBBBB nCCCCC       How do I make it so that the UILabel display the message like this        AAAAA   BBBBB   CCCCC   I don t think  n is recognized by UILabel  so is there anything that I can put inside NSString so that UILabel knows that it has to create a line break there

In my case also  n was not working  I fixed issue by keeping number of lines to 0 and copied and pasted the text with new line itself for example instead of Hello  n World  i pasted      Hello      World   in the interface builder

Use  n as you are using in your string   Set numberOfLines to 0 to allow for any number of lines   label numberOfLines   0   Update the label frame to match the size of the text using sizeWithFont    If you don t do this your text will be vertically centered or cut off   UILabel  label     set frame to largest size you want     CGSize labelSize    label text sizeWithFont label font                           constrainedToSize label frame size                               lineBreakMode label lineBreakMode   label frame   CGRectMake      label frame origin x  label frame origin y       label frame size width  labelSize height     Update   Replacement for deprecatedsizeWithFont constrainedToSize lineBreakMode   Reference  Replacement for deprecated sizeWithFont  in iOS 7   CGSize labelSize    label text sizeWithAttributes   NSFontAttributeName label font     label frame   CGRectMake      label frame origin x  label frame origin y       label frame size width  labelSize height

It seems wrong to me to change the label frame sizes especially when using autolayout   Using the appendFormat method seems more appropriate   Here is my example   NSMutableString  list     NSMutableString alloc  init   NSArray  textArray       AAAA     BBBB    for  NSString  string in textArray         list appendFormat      n   string mutableCopy     self label text   list  self label numberOfLines   0

If you set your UILable properties from Plain to Attributed   the UILabel will hold multiline text no matter how many paragraphs for along as your UILabel height and width are set to fit the screen area you want to display the text in

On Xcode 6  you can just use  n even inside a string when using word wrap  It will work  So for example   UILabel  label     UILabel alloc initWithFrame CGRectMake 0  100  screenRect size width  50    label textAlignment   NSTextAlignmentCenter  label text     This will be on the first line nfollowed by a line under it    label lineBreakMode   UILineBreakModeWordWrap  label numberOfLines   0

If you read a string from an XML file  the line break  n in this string will not work in UILabel text  The  n is not parsed to a line break   Here is a little trick to solve this issue      correct next line  n in string from XML file NSString  myNewLineStr      n   myLabelText    myLabelText stringByReplacingOccurrencesOfString     n  withString myNewLineStr    myLabel text   myLabelText    So you have to replace the unparsed  n part in your string by a parsed  n in a hardcoded NSString   Here are my other label settings   myLabel numberOfLines   0  myLabel backgroundColor    UIColor lightGrayColor   myLabel textColor    UIColor redColor    myLabel font    UIFont fontWithName   Helvetica Neue  size 14 0      myLabel textAlignment   UITextAlignmentCenter    Most important is to set numberOfLines to 0    unlimited number of lines in label    No idea why Apple has chosen to not parse  n in strings read from XML   Hope this helps

If your using a UILabel you have to remember that the default setting is 1 line  so it does not matter how many breaks you add   n or  r   you need to make sure it is set to more than one line so it could be allowed to append more lines   One alternative is to use UITextView which is really meant for multilines   You can easily achieve this in XCode attribute section of the UILabel  see screenshot
