根据要显示的文字以及UILable本身的字体,来计算能够完全显示所有文字的label所需要的大小,从而进行调整。
代码语言:javascript复制//Calculate the size necessary for the UILable
NSString *theText = @"Texting";
CGSize theStringSize = [theText sizeWithFont:font
constrainedToSize:theLabel.frame.size
lineBreakMode:theLabel.lineBreakMode];
//Adjust the size of the UILable
theLable.frame = CGRectMake(theLable.frame.origin.x,
theLable.frame.origin.y,
theStringSize.width, theStringSize.height);
theLable.text = theText;</pre>
