答
这就是我所做的.它的作用就像黄油一样.
This is what i did. It works like butter.
1) 将 CoreText.framework 添加到您的框架中.
1) Add CoreText.framework to your Frameworks.
2) 在需要下划线标签的类中导入
2) import <CoreText/CoreText.h> in the class where you need underlined label.
3) 编写以下代码.
NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithString:@"My Messages"];
[attString addAttribute:(NSString*)kCTUnderlineStyleAttributeName
value:[NSNumber numberWithInt:kCTUnderlineStyleSingle]
range:(NSRange){0,[attString length]}];
self.myMsgLBL.attributedText = attString;
self.myMsgLBL.textColor = [UIColor whiteColor];
