问题 I'm adding a UILabel to each cell in my table view. This presents no problem initially. When I round the corners of the UILabel using layer.cornerRadius scrolling the table view grinds to a halt. UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(cell.bounds.origin.x+10 ,5, 30, 30)]; label1.backgroundColor = ([[managedObject valueForKey:@"color"] hasPrefix:@"FFFFFF"]) ? [UIColor blackColor] : color; label1.layer.cornerRadius = 10.0f; [cell addSubview:label1]; 回答1: I've tried this

问题 Is there a way to use non breaking spaces in UILabel text? For example, I have label with 2 lines and line breaking mode set to word wrap. The content for this label is read from database, where it's stored as a string.

问题 In iOS 6, I am using : CGSize labelSize = [self.text sizeWithFont:self.font constrainedToSize:size lineBreakMode:self.lineBreakMode]; self.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y , labelSize.width, self.frame.size.height); To dynamically resize a UILabel. This does not work in iOS 7 so I tried: NSString *text = self.text; CGFloat width = size.width; UIFont *font = self.font; NSAttributedString *attributedText = [[NSAttributedString alloc] initWithString:text attributes:@{

问题 I have tried to search for solutions for this problem, but I am not even able to put it correctly in words I guess.

问题 I'm new to iPhone and Mac programming (developed for Windows before), and I've got a question: How do I animate the text property of an UILabel between two numbers, e.g. from 5 to 80 in an Ease-Out style?

It doesn't look very nice when it just goes from 50 to 100 or something like that without animation.
