如何设置NSPopupButton菜单项的颜色

Question

这是一个答案,而不是一个问题.在线搜索,我发现这个问题的答案真的被黑了,扭曲了(http://www.cocoabuilder.com/archive/cocoa/58379-changing-the-text-color-of-an-nsmenuitem-in-an- nspopupbutton.html),可以更优雅地回答:

NSArray *itemArray = [scalePopup itemArray];
int i;
NSDictionary *attributes = [NSDictionary
                            dictionaryWithObjectsAndKeys:
                            [NSColor redColor], NSForegroundColorAttributeName,
                            [NSFont systemFontOfSize: [NSFont systemFontSize]],
                            NSFontAttributeName, nil];

for (i = 0; i < [itemArray count]; i++) {
    NSMenuItem *item = [itemArray objectAtIndex:i];

    NSAttributedString *as = [[NSAttributedString alloc] 
             initWithString:[item title]
             attributes:attributes];

    [item setAttributedTitle:as];
}

在网上搜索，我只找到了这个问题的一个非常被黑的、扭曲的答案，可以更优雅地回答，如下所示：

NSArray *itemArray = [scalePopup itemArray];
int i;
NSDictionary *attributes = [NSDictionary
                            dictionaryWithObjectsAndKeys:
                            [NSColor redColor], NSForegroundColorAttributeName,
                            [NSFont systemFontOfSize: [NSFont systemFontSize]],
                            NSFontAttributeName, nil];

for (i = 0; i < [itemArray count]; i++) {
    NSMenuItem *item = [itemArray objectAtIndex:i];
    
    NSAttributedString *as = [[NSAttributedString alloc] 
             initWithString:[item title]
             attributes:attributes];
    
    [item setAttributedTitle:as];
}
