Objective c 从模式视图启动相机会导致iPad上出现不必要的调整大小

在我的iPad应用程序中，我创建并调整模式视图的大小，如下所示：

ModalViewController *modalController = [[WishlistInfoViewController alloc] initWithNibName:@"WishlistInfoViewController" bundle:nil];

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:modalController];
navController.modalPresentationStyle = UIModalPresentationPageSheet; 

self presentViewController:navController animated:YES completion:nil];

navController.view.superview.bounds = CGRectMake(0, 0, 700, 700);
navController.view.superview.center = CGPointMake(self.view.center.x, self.view.center.y + 35);

UIImagePickerController *mypicker = [[UIImagePickerController alloc] init];
mypicker.delegate = self; 
mypicker.allowsEditing = NO; 
mypicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
mypicker.showsCameraControls = YES;
mypicker.wantsFullScreenLayout = YES;
[self.navigationController presentModalViewController:mypicker animated:YES];

[self dismissModalViewControllerAnimated:TRUE]; 

在该模态视图中，我按如下方式启动相机：

ModalViewController *modalController = [[WishlistInfoViewController alloc] initWithNibName:@"WishlistInfoViewController" bundle:nil];

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:modalController];
navController.modalPresentationStyle = UIModalPresentationPageSheet; 

self presentViewController:navController animated:YES completion:nil];

navController.view.superview.bounds = CGRectMake(0, 0, 700, 700);
navController.view.superview.center = CGPointMake(self.view.center.x, self.view.center.y + 35);

UIImagePickerController *mypicker = [[UIImagePickerController alloc] init];
mypicker.delegate = self; 
mypicker.allowsEditing = NO; 
mypicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
mypicker.showsCameraControls = YES;
mypicker.wantsFullScreenLayout = YES;
[self.navigationController presentModalViewController:mypicker animated:YES];

[self dismissModalViewControllerAnimated:TRUE]; 

我像这样关闭相机：

ModalViewController *modalController = [[WishlistInfoViewController alloc] initWithNibName:@"WishlistInfoViewController" bundle:nil];

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:modalController];
navController.modalPresentationStyle = UIModalPresentationPageSheet; 

self presentViewController:navController animated:YES completion:nil];

navController.view.superview.bounds = CGRectMake(0, 0, 700, 700);
navController.view.superview.center = CGPointMake(self.view.center.x, self.view.center.y + 35);

UIImagePickerController *mypicker = [[UIImagePickerController alloc] init];
mypicker.delegate = self; 
mypicker.allowsEditing = NO; 
mypicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
mypicker.showsCameraControls = YES;
mypicker.wantsFullScreenLayout = YES;
[self.navigationController presentModalViewController:mypicker animated:YES];

[self dismissModalViewControllerAnimated:TRUE];

问题是，当我关闭相机时，模式视图的大小将调整为填满整个屏幕。如何防止模式视图调整大小

好的，所以我解决了我的问题，但只是在调用[self dismissModalViewControllerAnimated:YES]之后重置了视图的大小；。我不知道为什么我直到现在才尝试这个方法。

Log.d记录大小的值，并检查它到底在哪里增加，我的意思是在什么点。尝试将此设置为否，mypicker.wantsFullScreenLayout=NO；你在哪里打电话给dismissModalViewController？这可能与您的确切问题无关，但您应该尝试在调用第一个模态视图的视图中始终忽略该问题。您可以使用委托或parentViewController来完成此操作。我尝试了WantFullScreenLayout=NO，但没有任何效果，我尝试从两个视图中删除，但仍然没有任何效果。我确实试着用[self.view.window addSubview:mypicker.view]来调用它，这是可行的，但是我在相机视图中的旋转出现了问题。
