2 line text UIButton

Question

I have a UIButton and the text of the button is filled by a randomiser. However my problem is that sometimes the number of characters in a text is too many, leading to the button now showing the whole text.

Would it be possible to check if the characters are too many and then have it drop the rest of the text to another text line? So basically having to text lines instead of one for the UIButton?

Answer 1

Objectivc-C

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
button.titleLabel.numberOfLines = 2;
button.titleLabel.textAlignment = NSTextAlignmentCenter; // if u need

else use this

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
button.titleLabel.textAlignment = NSTextAlignmentCenter;
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

Swift

button.titleLabel!.lineBreakMode = .ByWordWrapping
button.titleLabel!.numberOfLines = 2
button.titleLabel!.textAlignment = .Center

else use this

button.titleLabel!.lineBreakMode = .ByWordWrapping
button.titleLabel!.textAlignment = .Center
button.setTitle("Line1\nLine2", forState: .Normal)

Swift3

buttonName.titleLabel!.lineBreakMode = .byWordWrapping
buttonName.titleLabel!.textAlignment = .center
buttonName.setTitle("Line1\nLine2", for: .normal)

Answer 2

In the Interface Builder, change the Line Break mode to Word Wrap for the UIButton control:

And to center the text, make the title Attributed instead of Plain.
