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(self.view.frame.size.width-label.frame.origin.x*2, 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; }
