如何设置NSButtonCell文本标签的颜色

Question

如何设置NSButtonCell的标签(标题)文本的颜色，即表格视图的列单元格？在我的例子中，它是复选框按钮单元格。(是否可以使用IB?)

Answer 1

试试这个吧，我觉得它很完美。

NSColor *color = [NSColor redColor];
NSMutableAttributedString *colorTitle =
    [[NSMutableAttributedString alloc] initWithAttributedString:[button attributedTitle]];

NSRange titleRange = NSMakeRange(0, [colorTitle length]);

[colorTitle addAttribute:NSForegroundColorAttributeName
                   value:color
                   range:titleRange];

[button setAttributedTitle:colorTitle];

Answer 2

你可以尝试一个属性字符串值。

NSColor *txtColor = [NSColor redColor];
NSFont *txtFont = [NSFont boldSystemFontOfSize:14];
NSDictionary *txtDict = [NSDictionary dictionaryWithObjectsAndKeys:
        txtFont, NSFontAttributeName, txtColor, NSForegroundColorAttributeName, nil];
NSAttributedString *attrStr = [[[NSAttributedString alloc]
        initWithString:@"Hello!" attributes:txtDict] autorelease];
[[attrStrTextField cell] setAttributedStringValue:attrStr];
[attrStrTextField updateCell:[attrStrTextField cell]];
