目前UIImagePickerController崩溃了

Question

如果您创建一个新项目（单视图应用程序）并添加：

，它甚至可以轻松复制

// Swift
override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    present(UIImagePickerController(), animated: true)
}

或

// Objective-C
- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    [self presentViewController:[UIImagePickerController new] animated:YES completion:NULL];
}

它在iPhone 7模拟器上崩溃。

为什么会发生这种情况？
