I have faced same problem, and here is, how i solved the problem. Hope this will be helpful for someone.

// Swift 2

   lblMultiline.lineBreakMode = .ByWordWrapping // or use NSLineBreakMode.ByWordWrapping
   lblMultiline.numberOfLines = 0 

// Objective-C

  lblMultiline.lineBreakMode = NSLineBreakByWordWrapping;
  lblMultiline.numberOfLines = 0;

// C# (Xamarin.iOS)

  lblMultiline.LineBreakMode = UILineBreakMode.WordWrap;
  lblMultiline.Lines = 0;

For those of you who want an easy solution, do the following in the text Label input box in Interface Builder:

Make sure your number of lines is set to 0.

Answer 3

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;

Answer 4

You have to set the numberOfLines property on the UILabel. The default is 1, if you set it to 0 it will remove all limits.

Answer 5

Important to note it's \n (backslash) rather than /n.

Answer 6

In xCode 11, Swift 5 the \n works fine, try the below code:

textlabel.numberOfLines = 0
textlabel.text = "This is line one \n This is line two \n This is line three"
