NSParagraphStyle line spacing ignored

Question

A simple test that is failed: Make a new project with just one subview (UITextView) and put the following in:

- (void)viewDidLoad
{
    [super viewDidLoad];         


        

Answer 1

Setting maximumLineHeight seems to resolve this issue for me;

CGFloat fontSize = 22.f;
titleLabel.font = [UIFont boldSystemFontOfSize:fontSize];
NSMutableParagraphStyle *paragraphStyle = [[[NSMutableParagraphStyle  alloc] init] autorelease];
paragraphStyle.maximumLineHeight = fontSize/2;
titleLabel.attributedText = [[[NSAttributedString alloc]
                              initWithString:@"This is a test.\nWill I pass?"
                              attributes: @{ NSParagraphStyleAttributeName : paragraphStyle,
                                             NSFontAttributeName : titleLabel.font}]
                             autorelease];
