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?

Answer 1

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).

Answer 2

myUILabel.numberOfLines = 0;
myUILabel.text = @"your long string here";
[myUILabel sizeToFit];

Answer 3

UILabel *helpLabel = [[UILabel alloc] init];
NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:label];
helpLabel.attributedText = attrString;
// helpLabel.text = label;

helpLabel.textAlignment = NSTextAlignmentCenter;
helpLabel.lineBreakMode = NSLineBreakByWordWrapping;
helpLabel.numberOfLines = 0;

For some reasons its not working for me in iOS 6 not sure why. Tried it with and without attributed text. Any suggestions.

Answer 4

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;

Answer 5

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).

Answer 6

Use this to have multiple lines of text in UILabel:

textLabel.lineBreakMode = NSLineBreakByWordWrapping;
textLabel.numberOfLines = 0;

Swift:

textLabel.lineBreakMode = .byWordWrapping
textLabel.numberOfLines = 0
