objective-c - wait_fences : failed to receive reply: 10004003 error still appearing

Question

我读过它与发布 subview 有关，例如 UIAlertView或诸如文本响应器之类的东西。这是我的 UIAlertView 的代码正在被调用...
如果有人可以提供帮助，将不胜感激。

- (void)viewDidAppear:(BOOL)animated {  
    reachability = [Reachability reachabilityForInternetConnection];
    NetworkStatus internetStatus = [reachability currentReachabilityStatus];

    if (internetStatus == NotReachable) {
        UIAlertView *errorView;

        errorView = [[UIAlertView alloc] initWithTitle: NSLocalizedString(@"Network error", @"Network error") message: NSLocalizedString(@"No internet connection found, this application requires an internet connection to gather the data required.", @"Network error") delegate: self cancelButtonTitle: NSLocalizedString(@"Close", @"Network error") otherButtonTitles: nil];

        [errorView show];
        [errorView autorelease];
    }
}

在顶部添加 [super viewDidAppear:animated]。

似乎警报委托(delegate)也可以设置为 nil，因为用户只能选择关闭警报。
