NSButton如何给文本上色 [英] NSButton how to color the text

问题描述

在OSX上，我有一个带有深色图像的NSButton，不幸的是，无法使用属性检查器更改颜色.看到图片上的黑色大按钮，文字为 Go .

on OSX I have an NSButton with a pretty dark image and unfortunately it is not possible to change the color using the attributes inspector. See picture the big black button, the text is Go.

是否有任何可能更改文本颜色的线索?我查看了NSButton类，但是没有方法可以做到这一点.我知道我可以用白色字体制作图像，但这不是我想要的.

Any clues for a possibility to change the text color? I looked in to the NSButton class but there is no method to do that. I´m aware that I could make the image with white font but that is not what I want to do.

Here is two other solutions: http://denis-druz.okis.ru/news.534557.Text-Color-in-NSButton.html

解决方案1:

-(void)awakeFromNib
{
    NSColor *color = [NSColor greenColor];
    NSMutableAttributedString *colorTitle = [[NSMutableAttributedString alloc] initWithAttributedString:[button attributedTitle]];
    NSRange titleRange = NSMakeRange(0, [colorTitle length]);
    [colorTitle addAttribute:NSForegroundColorAttributeName value:color range:titleRange];
    [button setAttributedTitle:colorTitle];
}

解决方案2:

在* .m文件中:

- (void)setButtonTitleFor:(NSButton*)button toString:(NSString*)title withColor:(NSColor*)color
{
    NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
    [style setAlignment:NSCenterTextAlignment];
    NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObjectsAndKeys:color, NSForegroundColorAttributeName, style, NSParagraphStyleAttributeName, nil];
    NSAttributedString *attrString = [[NSAttributedString alloc]initWithString:title attributes:attrsDictionary];
    [button setAttributedTitle:attrString];
}

-(void)awakeFromNib
{
    NSString *title = @"+Add page";
    NSColor *color = [NSColor greenColor];
    [self setButtonTitleFor:button toString:title withColor:color];
}
