    Updated answer for more recent iOS versions

    Since this is the accepted answer, added @Sean's answer here:

    Set these properties on the titleLabel of your button.

    button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
    button.titleLabel.numberOfLines = 2; // if you want unlimited number of lines put 0
    

    Swift 3 and 4:

    button.titleLabel?.lineBreakMode = .byWordWrapping
    button.titleLabel?.numberOfLines = 2 // if you want unlimited number of lines put 0
    

    Original answer for an older version of iOS

    If you want 2 lines of text on top of your UIButton you should add a UIlabel on top of it that does precisely that.

    UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(15, 10, frame.size.width-100, 100)];
    titleLabel.font = [UIFont boldSystemFontOfSize:24.0];
    titleLabel.text = @"This text is very long and should get truncated at the end of the second line";
    titleLabel.numberOfLines = 2;
    titleLabel.lineBreakMode = UILineBreakModeTailTruncation;
    [myButton addSubview:titleLabel]; //add label to button instead.
    

    Updated for interface builder solution

    Added @Borut Tomazin's answer for a more complete answer. Updated this part again since the answer of @Borut Tomazin was improved.

    You can do this much easier, with no code required. In Interface Builder set Line Break on UIButton to Word Wrap. Than you can insert multiple lines of title. Just hit Option + Return keys to make new line. You will also need to add this to the User Defined Runtime Attribute in Interface Builder:

    titleLabel.textAlignment Number [1]
