Popover with ModalPresentationStyle is not centered in iOS 7 iPad

Question

I have a problem with iOS 7 that seems to be a bug or I just don\'t do something right. I have modalViewController that appears as a popover on iPad with ModalPresentationStyle.

Answer 1

I had the same problem. I have solved this by using another approach, found here.

What this solution proposes is to use the method (void)viewWillLayoutSubviews

So in case of @Manuel M. inside the GeneralSettingsViewController add the code below:

// GeneralSettingsViewController
- (void)viewWillLayoutSubviews{
    [super viewWillLayoutSubviews];
    self.view.superview.bounds = CGRectMake(0, 0, 497, 375);
}

And you won't need this code anymore:

self.generalSettingsVC.view.superview.frame = CGRectMake(0, 0, 497, 375);
self.generalSettingsVC.view.superview.center = self.view.center;

For @titicaca, you are using a UINavigationController I haven't test it with this Controller but you could try the same solution I mentioned, extending the UINavigationController and overwrite the viewWillLayoutSubviews method.

[EDIT]

For @titicaca I tried it in a new project and for me it worked. What I did was having a custom navigation view controller CustomNavigationController overriding the viewWillLayoutSubviewslike this:

- (void)viewWillLayoutSubviews{
    [super viewWillLayoutSubviews];
    self.view.superview.bounds = CGRectMake(0, 0, 330, 284);
}

Then, the view controller that presents the CustomNavigationController should execute a code similar to this:

UIViewController *myVC = [[UIViewController alloc] init];
[myVC.view setBackgroundColor:[UIColor redColor]];

CustomNavigationController *nav = [[CustomNavigationController alloc] initWithRootViewController:myVC];
[nav setModalPresentationStyle:UIModalPresentationFormSheet];
[nav setModalTransitionStyle: UIModalTransitionStyleFlipHorizontal];

[self presentViewController:nav animated:YES completion:nil];

You need to make sure though, that the dimensions of the self.view.superview.bounds = CGRectMake(0, 0, 330, 284); are even numbers otherwise the text inside gets fuzzy, if there is any
