_NXTermWindow：错误释放窗口（1001）？

Question

这不是一个非常重要的问题，但我很好奇它为什么会发生。基本上，我使用以下代码打开NSSharingService窗口：

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    // Get the sharable items from a custom method
    NSArray *shareItems = self.sharableItems;

    // Pick service dependent on type sent via JS
    NSSharingService *service;
    if ([shareType isEqualToString:@"Messages"]){
        service = [NSSharingService sharingServiceNamed:NSSharingServiceNameComposeMessage];
    } else if ([shareType isEqualToString:@"Email"]){
        service = [NSSharingService sharingServiceNamed:NSSharingServiceNameComposeEmail];
    } else if ([shareType isEqualToString:@"Facebook"]){
        service = [NSSharingService sharingServiceNamed:NSSharingServiceNamePostOnFacebook];
    } else if ([shareType isEqualToString:@"Twitter"]){
        service = [NSSharingService sharingServiceNamed:NSSharingServiceNamePostOnTwitter];
    }
    service.delegate = self;

    // Update the UI in the main thread
    dispatch_async(dispatch_get_main_queue(), ^{
        [service performWithItems:shareItems];
    });
});

NSSharingService窗口正常打开，但当我发送＆＃34;发送＆＃34;或者＆＃34;取消＆＃34;发送消息，控制台输出：

Google produced no helpful results。值得注意的是，我实施了以下相关方法：

- (NSWindow *)sharingService:(NSSharingService *)sharingService sourceWindowForShareItems:(NSArray *)items sharingContentScope:(NSSharingContentScope *)sharingContentScope{
    return self.window;
}

- (void)sharingService:(NSSharingService *)sharingService didShareItems:(NSArray *)items;

- (void)sharingService:(NSSharingService *)sharingService didFailToShareItems:(NSArray *)items error:(NSError *)error;
