How to Dismiss 2 Modal View Controllers in Succession?

Question

I have 2 view controllers presented modally.

A presents B which presents C.

When I dismiss C I would like to dismiss B as well. But I am not sure how to do this:

Dismiss C:

[self dismissModalViewControllerAnimated:YES]
//[delegate dismissB] //this doesn't work either when i create a delegate pattern

Now I am left with B. How can I dismiss B from C?

Answer 1

Just found out you need to use presentingViewController in iOS 5.

[self.presentingViewController.presentingViewController dismissModalViewControllerAnimated:YES];

A -> B -> C

Running the above code in modal C will take you back to A

Answer 2

This worked for me, very simple

// Call inside View controller C    
self.presentingViewController?.dismissViewControllerAnimated(false, completion: nil)
self.presentingViewController?.dismissViewControllerAnimated(true, completion: nil)

Explanation:

If you call dismiss on C, it can only remove C. If you call dismiss on B, it will do the right thing: Remove the topmost modal view controller. The first call therefore removes C (with no animation). The second call removes B.

The easiest way to access view controller B from C is to use the presentingViewController variable.

Answer 3

In B. Put:

[self dismissModalViewControllerAnimated:NO];
[self dismissModalViewControllerAnimated:YES];

Only run one animation.

Answer 4

In swift 4

self.presentingViewController?.presentingViewController?.dismiss(animated: true, completion: nil);

Answer 5

Try using the next code in B (right after dismissing C, as you already do):

[self.parentViewController dismissModalViewControllerAnimated:YES];

IMPORTANT:
Don't do anything in the method after this line.
This view controller (B) probably will be released and deallocated...

UPDATE:
Starting from iOS7 the method above is deprecated.
Use the next method instead:

[self.parentViewController dismissViewControllerAnimated:YES completion:^{ /* do something when the animation is completed */ }];

Answer 6

Check this for swift:

self.presentingViewController?.presentingViewController?.dismissViewControllerAnimated(true, completion: nil);

Answer 7

This worked for me:

// Swift
presentingViewController?.dismissViewControllerAnimated(true, completion: nil)

// Objective-C
[self.presentingViewController dismissViewControllerAnimated:true completion:nil];

Answer 8

I read all the topics and I didn't find a proper answer. If you dismiss B, than C will immediately disappear and create a weird effect. The proper way is to present C as a child view controller with custom animation from the bottom, like:

   [b addChildViewController:c];
    c.view.frame = CGRectOffset(b.view.bounds, 0, b.view.bounds.size.height);
    [b.view addSubview:c.view];
    [c didMoveToParentViewController:b];

    [UIView animateWithDuration:0.5 animations:^{
        c.view.frame = CGRectOffset(c.view.frame, 0, -b.view.bounds.size.height);
    } completion:^(BOOL finished) {

    }];

And then you simply dismiss B and it all looks much nicer!

Answer 9

You only need one dismiss command. Just dismiss B, and then C will go away with it.

Answer 10

Inspired by Albertos solution, I created a delegate method in B with a block to show a result of deleting an account:

#pragma - mark - AddAccountViewControllerDelegate Methods

- (void) dismissToSettings {
    [self dismissModalViewControllerAnimated:NO];
    [self dismissViewControllerAnimated:YES completion:^(void){[DKMessage showMessage:LS(@"Account was successfully created")];}];
}

Answer 11

I faced the same problem, and a better solution was creating a "DismissViewProtocol" as follow:

File: DismissViewProtocol.h

@protocol DismissViewProtocol <NSObject>
-(void)dismissView:(id)sender;
@end

In my B-modal view, let's response for the delegate method:

in my b.h file:

#import "DismissViewProtocol.h"
@interface B-Modal : UIViewController <DismissViewProtocol>
...
@end

in my b.m file:

-(void) dismissView:(id)sender
{
 [((UIViewController *) sender) dismissModalViewControllerAnimated:NO];
 [self dismissModalViewControllerAnimated:YES];
}

In the same B-view controller, when I call the Next, in my B modal view, when I call the other modal view C, supposing that for segue:

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    ((C-ViewController *)segue.destinationViewController).viewDelegate=self;
}

Finally, in my c.h file, lets prepare for the delegate:

@property(nonatomic, weak) id <DismissViewProtocol> viewDelegate;

And in my c.m file, I just tell my viewDelegate to dismiss my modal view controller and itself:

-(void)closeBothViewControls
{
       [self.viewDelegate dismissView:self];
}

And that's it.

Hope it works for all of you.

Answer 12

The navigation controller has a "viewControllers" property that is an array - you can set that to a new array minus the two view controllers you want to remove.

Answer 13

Here is a way how to dismiss more that one modal view controller using repeat cycle:

Swift 3

// In this example code will go throw all presenting view controllers and 
// when finds it then dismisses all modals.
var splitViewController: UIViewController? = self

repeat {
    splitViewController = splitViewController?.presentingViewController
} while (!(splitViewController is UISplitViewController) && (splitViewController != nil))

splitViewController?.dismiss(animated: true, completion: nil)

Answer 14

I know this answer may feel redundant, but the statement below should make sense and you get an idea of how this works.

Just dismiss the oldest view controller and all other later view controllers go away with this.

In case of 2 view controllers:

Objective C:

[self.presentingViewController dismissViewControllerAnimated:true completion:nil]

Swift:

presentingViewController?.dismissViewControllerAnimated(true, completion: nil)

Answer 15

I found a solution.

You can put these ViewControllers inside an individual NavigationController. And than dismiss the NavigationController will cause all these ViewControllers to dismiss at once.
