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

Answer 1

even for reducing the forma sheet height and width you can use

[self.view.superview setBounds:CGRectMake(0, 0, 450, 480)];

Answer 2

All these answers will not work on ios8 SDK.

This will work:

AboutViewController * _aboutViewController = [[AboutViewController alloc] init];
    _aboutViewController.modalPresentationStyle = UIModalPresentationFormSheet;
    if(IS_IOS8)
    {
        _aboutViewController.preferredContentSize = CGSizeMake(300, 300);
    }
    [self presentViewController:_aboutViewController animated:YES completion:nil];

In AboutViewController.m

- (void)viewWillLayoutSubviews{
    [super viewWillLayoutSubviews];

    if(!IS_IOS8)
    {
        self.view.superview.bounds = CGRectMake(0, 0, 300, 300);
    }
}

IS_IOS8

#define IS_IOS8 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8)

In iOS 8 you can also use UIPresentationController which gives you more customization options.

Answer 3

You can use MZFormSheetController like this:

MZFormSheetController *formSheet = [[MZFormSheetController alloc] initWithSize:customSize viewController:presentedViewController];
[presentingViewController mz_presentFormSheetController:formSheet animated:YES completionHandler:nil];

Answer 4

As some other users here, I also had the problem that the origin of the modal view controller was not correct. After some experiments, I found a solution that worked for me:

- (void)viewWillLayoutSubviews{
    [super viewWillLayoutSubviews];   
    self.view.superview.bounds = CGRectMake(0, 0, <width>, <height>);
}

Answer 5

Even I was struggling with the same issue for quite a while. After giving few tries from many of the answers given here I came up with a solution that worked for me pretty well.

Here is the code while presenting the view controller.

    SomeViewController *sovcObj = [[SomeViewController alloc] initWithNibName:@"SyncOptionsViewController" bundle:nil];
someObj.modalPresentationStyle = UIModalPresentationFormSheet;
someObj.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:someObj animated:YES completion:nil];
someObj.view.superview.bounds = CGRectMake(0, 0, 400, 400); // whatever width and height you want

In the xib (if you are using one) in the 'Simulated Metrics' section select 'Freeform' size.

Apart from this you need to write the below code in your presented view controller (i.e.., SomeViewController in this example)

- (void)viewWillLayoutSubviews{
[super viewWillLayoutSubviews];
self.view.superview.bounds = CGRectMake(0, 0, 400, 400); // whatever width and height you want

}

This code also works for iOS 7 as well

Answer 6

I had an issue getting the custom sized modal to center until I figured out what ViewController.view.superview.frame was set to initially. It is determined based on the UIModalPresentation type. superview.center isn't even needed(as far as my testing shows).

Also, I set the coordinates dynamically using [UIScreen mainScreen].applicationFrame, only supporting landscape orientation for now. You have to do a conditional check to support both portrait and landscape by flipping the X/Y and Height/Width values.

Here was my first working solution for iOS 6.0:

ViewController.modalPresentationStyle = UIModalPresentationFormSheet;
ViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:ViewController animated:YES completion:nil];
ViewController.view.superview.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
ViewController.view.superview.frame = CGRectMake(
                                                                    // Calcuation based on landscape orientation (width=height) 
                                                                    ([UIScreen mainScreen].applicationFrame.size.height/2)-(320/2),// X
                                                                    ([UIScreen mainScreen].applicationFrame.size.width/2)-(320/2),// Y
                                                                    320,// Width
                                                                    320// Height
                                                                    );

And then I looked at the previous answer and face palmed. Shortens my solution a tad by replacing the last line with:

ViewController.view.superview.bounds = CGRectMake(0, 0, 320, 320);

EDIT for final solution and remarks.
