Is there anyway of making a UILabel wrap to the next line or do I have to use a UITextView?
回答1:
You would need to set the numberOfLines property to 0 and explicitly specify its dimensions, either in IB or programmatically. However, if you have a lot of text to display, I would recommend using a UITextView.
回答2:
What you want is to adjust your label according to the content's size.
In iOS 6, AutoLayout will work a charm, you should set the label to have numberOfLines = 0
In a non AutoLayout scenario, you will also want to make sure the frame of your UILabel is adjusted to show the content that's on the next line.
