How can I dismiss two modal view controller in succession with animation?

Question

Yes, I know there's exactly same question, but I want to do this with double dismiss animation. How to Dismiss 2 Modal View Controllers in Succession?

my code is same as question above,

view controller A (in navigation controller) - modal view controller B - modal view controller C

here's pseudo code

notification to B (as delegate)      // I changed order of this two lines, 
dismiss C *without* animation    // but it was same. 

(notification from C, in B)
dismiss B *with* animation

If I use animation when I dismiss C, it doesn't work, B will not be dismiss, because dismiss animation of C is playing.

Problem is: I can't start another dismiss animation if there's animation playing.

Can I play dismiss animation in succession?

This is not only problem of dismiss animation, it can be also applied to other iOS animations.

P.S: I think I can use timer to wait until first animation ends, but it is dirty and not stable way, isn't it?

Small Talk: In my program,

A: article list view
B: write article view
C: login view (if user is not logged in)

today, I have to add join view, I have to dismiss 3 views in time lol how can I help this?

iOS 5.0 and higher:

[self.presentingViewController.presentingViewController dismissViewControllerAnimated:YES completion:nil];

This works if you have:

A - starting view controller
M1 - modally presented by A
M2 - modally presented by M1

Put that line of code in M2's view controller class (and a button or whatever to activate it), and it will "reach up" through the hierarchy and tell A to dismissViewControllerAnimated:...

However,Rahul Vyas's answer is probably a better approach for cases where you have an unknown number of modal view controllers stretching between "A" and the last Modal view.

Note that this doesn't dismiss with two animations. There's only one animation. After reading more carefully, I see that the OP specifically asked for two animations. My bad. – Bill Patterson Mar 07 '13 at 03:46

You can generate a NSNotification and then from the root where your first modal appears dismiss the first modal view controller and all the others will automatically disappear. I have done this in one of my app.

How do I get the first modal view controller in my root controller? Considering it could be one of many different classes – Gil Sand Jan 15 '15 at 11:04
You should definitely never use a NSNotification for this kind of communication! But otherwise.. this answer is 5 years old, maybe it was different in 2011. @Zil: you can while-loop through the presentingViewController property of your controller to get the root controller. – Ben Jun 22 '16 at 16:24
I ended up always stacking modals on a modal navigation controller and dismissing the navigation controller instead of the modals one by one – Gil Sand Jun 22 '16 at 16:25

[self dismissModalViewControllerAnimated:(BOOL)] doesn't work. The second animation doesn't fire. In iOS 5 you can use [self dismissViewControllerAnimated:YES completion:^{}]; but that's not backwards compatible to 4.0. I've only had success calling a delegate method that closes the modal view controller before presenting the new one.

Here is what worked form me, I had A->B, and then a container view "C "over B. Then I wanted C to dismiss back over to A,

The best way that worked for me was calling this my action in view C

self.presentingViewController?.dismiss(animated: true, completion: {})
self.presentingViewController?.presentingViewController?.dismiss(animated: true, completion: {})

This dismissed the Modal C, then dismisses B in a synchronous order. It worked better with the feel of my application

You can use [self dismissModalViewControllerAnimated:(BOOL)] when you want the view to dismiss the modal view. If you call this in both controllers it should work. I have not tried it myself but it seems logical.

I must add that if you need to present multiple modal views in a row maybe you should consider using different paradigms for some of them. For example, the login view could be an alertview instead of a modal view controller.

I've run into similar types of issues trying to get animations to work in succession. I've been meaning to try the following:

what if you put the call for the second animation (i.e. to dimiss B) inside a call to performSelectorOnMainThread? That would make me think the second animation would be forced to wait for the first to complete.

I haven't tested it yet though. Good luck - I'm very curious about what solution you come up with.

You can remove 2 view by using

[AviewController dismissModalViewControllerAnimated:YES];

Here AviewController is object of A. Hope this will help you.
