iPad custom size of modal view controller

Question

I have a couple of modal view controllers of certain size. I\'m trying to avoid the use of custom views (creating full screen black translucent overlay over current view, ad

This is my solution for a NOT autolayout view (never tried with autolayout) and compliant with iOS 7 and iOS 8.

At first be sure to call the modal view in this way:

CloudSettingsViewController *cloudController = [[CloudSettingsViewController alloc] initWithNibName:@"CloudSettingsView" bundle:nil];

CGRect originalBounds = cloudController.view.bounds;

cloudController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
cloudController.modalPresentationStyle = UIModalPresentationFormSheet;

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

With iOS 8 set the preferredContentSize in the viewDidLoad method of the modal view.

- (void)viewDidLoad {
    [super viewDidLoad];

    // backup of the original size (selected in interface builder)
    height = self.view.frame.size.height;
    width = self.view.frame.size.width;

    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8) // versioni successive ios 8
        self.preferredContentSize = CGSizeMake(width, height); // this is necessary to get the correct size of the modal view
}

This works ALSO when the modal view needs to display the keyboard on iPad.

With previous versions of iOS 8 you should set the bounds after presentViewController call:

[currentController presentViewController:controlPanelController animated:YES completion:nil];
if ([[[UIDevice currentDevice] systemVersion] floatValue] < 8) 
    cloudController.view.superview.bounds = originalBounds;//it's important to do this after
