ios - 按钮标题颜色

Question

我想设置带有下划线和棕色的按钮标题:

为此我正在做:

 NSMutableAttributedString *nearestLocation = [[NSMutableAttributedString alloc] initWithString:@"Locate Manually"];
[nearestLocation addAttribute:(NSString*)kCTUnderlineStyleAttributeName
                  value:[NSNumber numberWithInt:NSUnderlineStyleSingle]
                  range:(NSRange){0,[nearestLocation length]}];
[btn_manually setAttributedTitle:nearestLocation forState:UIControlStateNormal];
[btn_manually setTitleColor:[UIColor brownColor] forState:UIControlStateNormal];

它显示下划线而不是棕色。

Answer 1

尝试这样使用....

 [nearestLocation addAttribute:NSForegroundColorAttributeName value:[UIColor brownColor] range:NSMakeRange(0,[nearestLocation length])];
