NSStatusItem"kCG ..."失误 [英] NSStatusItem "kCG..." Errors

问题描述

由于某种原因，在控制台中我得到了

For some reason, in the Console I'm getting

:kCGErrorIllegalArgument:CGSUnregisterWindowWithSystemStatusBar:无效的窗口

: kCGErrorIllegalArgument: CGSUnregisterWindowWithSystemStatusBar: Invalid window

:kCGErrorFailure:设置一个断点@ CGErrorBreakpoint()到在记录错误时捕获错误.

: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.

使用(我认为)此代码...

with (I think) this code ...

- (void)applicationDidResignActive:(NSNotification*)aNotification
{
        statusItem = [[NSStatusBar systemStatusBar] 
                       statusItemWithLength:NSVariableStatusItemLength];
        [statusItem setHighlightMode:YES];
        [statusItem setEnabled:YES];

            //Set menubar item's tooltip
        [statusItem setToolTip:@"Nucleus"];
        [statusItem setMenu:theMenu];
            //Set the menubar item's title
        [statusItem setTitle:[NSString stringWithString:@"N"]];

    [statusItem retain];

}

- (void)applicationDidBecomeActive:(NSNotification*)aNotification
{
    [[NSStatusBar systemStatusBar] removeStatusItem:statusItem];
}

我相信这是堆栈跟踪(?):

I believe this is the stack trace (?) :

0x00007fff8667349b< +0000>推送％rbp
0x00007fff8667349c< +0001> mov％rsp，％rbp
0x00007fff8667349f< +0004> mov％edi，％eax
0x00007fff866734a1< +0006>离开q
0x00007fff866734a2< +0007> retq
0x00007fff866734a3< +0008> nop

0x00007fff8667349b <+0000> push %rbp
0x00007fff8667349c <+0001> mov %rsp,%rbp
0x00007fff8667349f <+0004> mov %edi,%eax

0x00007fff866734a2 <+0007> retq
0x00007fff866734a3 <+0008> nop

为什么?我该如何解决?

Why? How can I fix this?

我在Mac上使用可可粉吗?

I'm using Cocoa on Mac?

推荐答案

我不确定是什么导致了该错误，但是我确实注意到，每次应用程序停用时，您都会泄漏 statusItem .将 [statusItem release] 从statusBar中删除后，可能会有所帮助(它肯定会解决您的泄漏问题).

I'm not sure what's causing the error, but I do notice that you're leaking statusItem every time the application deactivates. Perhaps adding a [statusItem release] after removing it from the statusBar will help (it will definitely fix your leak).
