UILabel自适应高、宽

根据Label和字体大小自适应高度

- (void)getHeightWithLabel:(UILabel *)label andFontSize:(CGFloat)size

{

label.numberOfLines=0;

NSMutableAttributedString*labelString =[[NSMutableAttributedString alloc] initWithString:label.text];

[labelString addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:size] range:NSMakeRange(0, [labelString length])];

CGRect labelStringRect= [labelString boundingRectWithSize:CGSizeMake(label.frame.size.width,9999) options:NSStringDrawingUsesLineFragmentOrigin context:nil];

CGRect labelRect=label.frame;

labelRect.size.height=labelStringRect.size.height;

label.frame=labelRect;

label.attributedText=labelString;

}
