有时候开发中我们为了样式好看, 需要对文本设置富文本属性, 设置完后那么怎样计算其高度呢, 很简单, 方法如下:

 

- (NSInteger)hideLabelLayoutHeight:(NSString *)content withTextFontSize:(CGFloat)mFontSize{    NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];    paragraphStyle.lineSpacing = 10;  // 段落高度    NSMutableAttributedString *attributes = [[NSMutableAttributedString alloc] initWithString:content];    [attributes addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:mFontSize] range:NSMakeRange(0, content.length)];    [attributes addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, content.length)];    CGSize attSize = [attributes boundingRectWithSize:CGSizeMake(200, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading context:nil].size;    return attSize.height;}

 

   使用时:

[self hideLabelLayoutHeight:nameStr withTextFontSize:14]
