方式一：

objectivec 复制代码

NSMutableAttributedString *attStr = [NSMutableAttributedString new];

CGSize attSize = [attStr boundingRectWithSize:CGSizeMake(UIScreen.mainScreen.bounds.size.width, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading context:nil].size;

CGFloat height = size.height;

NSMutableAttributedString *attStr = $NSMutableAttributedString new$ ;

CGSize attSize = $attStr boundingRectWithSize:CGSizeMake(UIScreen.mainScreen.bounds.size.width, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin \| NSStringDrawingUsesFontLeading context:nil$ .size;

CGFloat height = size.height;

方式二：

objectivec 复制代码

NSMutableAttributedString *attStr = [NSMutableAttributedString new];

CGFloat height = [label sizeThatFits:CGSizeMake(UIScreen.mainScreen.bounds.size.width, CGFLOAT_MAX)].height;

NSMutableAttributedString *attStr = $NSMutableAttributedString new$ ;

CGFloat height = $label sizeThatFits:CGSizeMake(UIScreen.mainScreen.bounds.size.width, CGFLOAT_MAX)$ .height;
