UIAlertView removeFromSuperview不起作用

Question

我使用下面的代碼來顯示UIAlertView

UIAlertView * messageBox = [[UIAlertView alloc] initWithTitle: @"title"
                                                      message: @""
                                                     delegate: nil
                                            cancelButtonTitle: @"Cancel"
                                            otherButtonTitles: nil];



[messageBox show];

然后我使用NSNotification postNotificationName觸發並希望刪除或釋放UIAlerView

-(void)notificationEntry:(NSNotification *)notification{

    if (messageBox ) {
        //[messageBox removeFromSuperview];//this does not work neither
        [messageBox performSelectorOnMainThread:@selector(removeFromSuperview) withObject:nil waitUntilDone:NO];
        messageBox = nil;

    }
}

通知已觸發，但是

[messageBox removeFromSuperview];

[messageBox performSelectorOnMainThread:@selector(removeFromSuperview);

沒有辦法
