Question

Why doesn’t this work? It always returns 18 no matter the length of the string. There is this thread, but not a definitive answer.

    NSString * t = @"<insert super super long string here>";

    CGSize size = [t sizeWithFont:[UIFont systemFontOfSize:14.0] forWidth:285 lineBreakMode:UILineBreakModeWordWrap];

    NSLog(@"size.height is %f and text is %@", size.height, t);

Thanks,

Todd

Use sizeWithFont:constrainedToSize:lineBreakMode: instead.

NSString * t = @"<insert super super long string here>";
CGSize constrainSize = CGSizeMake(285, MAXFLOAT);
CGSize size = [t sizeWithFont:[UIFont systemFontOfSize:14.0] constrainedToSize:constrainSize lineBreakMode:UILineBreakModeWordWrap];
NSLog(@"size.height is %f and text is %@", size.height, t);
