根據Label和字體大小自適應高度

- (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;}

根據Label和字體大小自適應寬度

- (void)getWidthWithLabel:(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(9999, label.frame.size.height) options:NSStringDrawingUsesLineFragmentOrigin context:nil];    CGRect labelRect = label.frame;    labelRect.size.width = labelStringRect.size.width;    label.frame = labelRect;    label.attributedText = labelString;}
