    UIViewController *vc = [[UIViewController alloc] init];
    self.window.rootViewController = vc;
    vc.view.autoresizingMask = UIViewAutoresizingFlexibleWidth |    UIViewAutoresizingFlexibleHeight;

    MKMapView *map = [[MKMapView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

推荐答案

我也遇到了这个问题，并且发现它只是似乎与选择的调整大小选项一起出现（即调整视图大小时调整高度和宽度）。我没有使用自动布局。

I am also experiencing this, and have found that it only seems to occur with the resizing options selected (i.e. resize height and width with as view resizes). I'm not using Auto Layout.

如果我只是将一个MKMapView添加到视图中，这没问题，但是如果我选择调整大小，它会生成相同的消息如上所示。

If I just add a MKMapView to a view, it's no problem, but if I select the resizing, it generates the same messages as shown above.

（很抱歉，这是评论而非答案，但我不能在1票上添加评论，我认为这可能有助于诊断问题）

(Sorry that this is a comment not an answer, but I can't add comments on 1 vote, and I thought this may help diagnose the issue)

更新 - 我在其中一个测试设备上安装了8.1 Beta，我没有遇到此问题。很有可能这是一个被8.1地毯扫过的问题:)

UPDATE - I have installed 8.1 Beta on one of my test devices, and I am NOT experiencing this issue. There is a good chance this is an issue that's being swept under the 8.1 carpet :)
