Multiple lines of text in UILabel

Question

Is there a way to have multiple lines of text in UILabel like in the UITextView or should I use the second one instead

User · Answer

In IB  set number of lines to 0  allows unlimited lines   When typing within the text field using IB  use  alt-return  to insert a return and go to the next line  or you can copy in text already separated out by lines

Swift 3 Set number of lines zero for dynamic text information  it will be useful for varying text   var label   UILabel   let stringValue    A label nwith nmultiline text   label text   stringValue label numberOfLines   0 label lineBreakMode    byTruncatingTail    or  byWrappingWord label minimumScaleFactor   0 8      It is not required but nice to have a minimum scale factor to fit text into label frame

I found a solution   One just has to add the following code      Swift textLabel lineBreakMode    ByWordWrapping    or NSLineBreakMode ByWordWrapping textLabel numberOfLines   0      For Swift  gt   3 textLabel lineBreakMode    byWordWrapping    notice the  b  instead of  B  textLabel numberOfLines   0     Objective-C textLabel lineBreakMode   NSLineBreakByWordWrapping  textLabel numberOfLines   0      C   Xamarin iOS  textLabel LineBreakMode   UILineBreakMode WordWrap  textLabel Lines   0      Restored old answer  for reference and devs willing to support iOS below 6 0    textLabel lineBreakMode   UILineBreakModeWordWrap  textLabel numberOfLines   0    On the side  both enum values yield to 0 anyway

In this function pass string that you want to assign in label and pass font size in place of  self activityFont and pass label width in  place of 235  now you get label height according to your string  it will work fine    - float calculateLabelStringHeight  NSString   answer       CGRect textRect    answer boundingRectWithSize  CGSizeMake 235  10000000  options NSStringDrawingUsesLineFragmentOrigin attributes   NSFontAttributeName self activityFont  context nil       return textRect size height

If you have to use the    myLabel numberOfLines   0    property you can also use a standard line break    n    in code  to force a new line

You can do that via the Storyboard too     Select the Label on the view controller In the Attribute Inspector  increase the value of the Line option  Press Alt Cmd 4 to show Attributes Inspector  Double click the Label in the view controller and write or paste your text Resize the Label and or increase the font size so that the whole text could be shown

The best solution I have found  to an otherwise frustrating problem that should have been solved in the framework  is similar to vaychick s   Just set number of lines to 0 in either IB or code  myLabel numberOfLines   0    This will display the lines needed but will reposition the label so its centered horizontally  so that a 1 line and 3 line label are aligned in their horizontal position   To fix that add   CGRect currentFrame   myLabel frame  CGSize max   CGSizeMake myLabel frame size width  500   CGSize expected    myString sizeWithFont myLabel font constrainedToSize max lineBreakMode myLabel lineBreakMode    currentFrame size height   expected height  myLabel frame   currentFrame

Already answered  but you can do it manually in the storyboard too  Under Attributes Inspector for the Label  you can change Line Breaks to Word Wrap  or character wrap
