objective-c - 如何更改 Objective-C/Cocoa 中状态栏项目标题的颜色？

Question

//Create the NSStatusBar and set its length
statusItem = [[[NSStatusBar systemStatusBar] statusItemWithLength:NSSquareStatusItemLength] retain];

[statusItem setHighlightMode:YES];
[statusItem setTitle:@"myTitle"];
[statusItem setToolTip:@"myToolTip"];
[statusItem setMenu:statusMenu];
[statusItem setEnabled:YES];

如何将“myTitle”的颜色改为蓝色？

某些应用程序(如 PeerGuardian)会在其列表被禁用时将其状态栏项目标题更改为红色，所以我想这在某种程度上是可能的。

Answer 1

使用 NSStatusItem 的 -setAttributedTitle 方法，并给它一个适当颜色的 NSAttributedString:

NSDictionary *titleAttributes = [NSDictionary dictionaryWithObject:[NSColor blueColor] forKey:NSForegroundColorAttributeName];
NSAttributedString* blueTitle = [[NSAttributedString alloc] initWithString:@"myTitle" attributes:titleAttributes];

statusItem = [[[NSStatusBar systemStatusBar] statusItemWithLength:NSSquareStatusItemLength] retain];
[statusItem setAttributedTitle:blueTitle];
[blueTitle release];
