我想知道状态栏图标在屏幕上的位置

-(void)awakeFromNib{
    statusItem = [[[NSStatusBar systemStatusBar] statusItemWithLength:NSVariableStatusItemLength] retain];
    NSBundle *bundle = [NSBundle mainBundle];
    statusImage = [[NSImage alloc] initWithContentsOfFile:[bundle pathForResource:@"r" ofType:@"png"]];
    statusHighlightImage = [[NSImage alloc] initWithContentsOfFile:[bundle pathForResource:@"rh" ofType:@"png"]]; 
    [statusItem setImage:statusImage];
    [statusItem setAlternateImage:statusHighlightImage];
    [statusItem setTitle:@"APP"];
    [statusItem setToolTip:@"You do not need this..."];
    [statusItem setHighlightMode:YES];

    NSRect rect = [[[statusItem view] window ] frame];

    NSLog(@"%f",rect.origin.y);

}

这样做并没有达到目的

NSRect rect = [[[statusItem view] window ] frame];

NSLog(@"%f",rect.origin.y);

您尚未为状态项设置自定义视图，因此调用

view

将返回nil

我猜您想知道位置的原因是当您单击状态项时

如果要为状态项实施操作，它可能如下所示：

- (IBAction)someAction:(id)sender
{
    NSWindow *window = [[[NSApplication sharedApplication] currentEvent] window];
    NSRect rect = [window frame];

    NSLog(@"%f",rect.origin.y);
}

[statusItem setAction:@selector(someAction:)];

然后将状态项的操作设置为：

- (IBAction)someAction:(id)sender
{
    NSWindow *window = [[[NSApplication sharedApplication] currentEvent] window];
    NSRect rect = [window frame];

    NSLog(@"%f",rect.origin.y);
}

[statusItem setAction:@selector(someAction:)];

然后，无论何时单击状态项，您都会在日志中看到类似的内容：

2012-04-17 20:40:24.344 test[337:403] 1578.000000

例如，可以使用该信息相对于状态项定位窗口（如Matt Gemmell的MAAttachedWindow）
