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?

Solution 1

Set the line break mode to word-wrapping and the number of lines to 0:

// Swift
textLabel.lineBreakMode = .byWordWrapping
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.

Solution 2

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).

Solution 3

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;

Solution 4

Use this to have multiple lines of text in UILabel:

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

Swift:

textLabel.lineBreakMode = .byWordWrapping
textLabel.numberOfLines = 0

Solution 5

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