I have 2 UIViewController's presented with [self presentViewController:viewController animated:YES completion:nil];, I want to dismiss the first one of them, without animation (It's not visible to the user anyway) and when the second one (currently visible) will be dismissed, the user will see the parent view controller who present them both.
- Parent
- First -> Dismiss first without animation
- Second -> Dismiss second with animation
How can I do that?
With your current view controller hierarchy if first view controller will be dismissed it will dismiss second view controller automatically. If you don't want that behaviour than make parent present second view controller. You can do that from first view controller by using [self.presentingViewController presentViewController:secondViewController animated:YES completion:nil]
Why do you want to do this?
You should do it like this for cleaner view hierarchy and better user experience:
Present first view controller :
[self presentViewController:viewController1 animated:YES completion:nil];
Dismiss first & present second view controller :
__weak MyViewController *aBlockSelf = self;
[self dismissViewControllerAnimated:YES completion:^{
[aBlockSelf presentViewController:viewController2 animated:YES completion:nil];
}];

i have a view controller and i need to dismiss it and present it back in same time.
i had tried dismiss it and call back the view controller but not working.
[self dismissViewControllerAnimated:YES completion:nil];
UIStoryboard *storyboard=[UIStoryboard storyboardWithName:#"Main" bundle:nil];
ExpandViewController *expandView=
[storyboard instantiateViewControllerWithIdentifier:#"ExpandViewController"];
expandView.delegate=self;
[expandView setEventDict:dict];
[self presentViewController:expandView animated:YES completion:NULL];
I am not exactly sure what outcome/functionality you are looking for in your question, but #matt is correct. However, you may be looking to have this happen seamlessly. Therefore you could use child view controllers instead of presenting the view controller using the [self presentViewController:VC animated:animate completion:nil] method.
Adding child vc:
[self addChildViewController:myVC];
[self.view addSubview:myVC.view];
[myVC didMoveToParentViewController:self];
Removing child vc:
[myVC willMoveToParentViewController:nil];
... remove subview.
You can set up a delegate between the two controllers to tell the parent when to dismiss the view to make things easy. You can also add the subviews at different indexes using [self.view insertSubview:myVC atIndex:index] or the other possible functions such as the insert above subview etc, to have one subview be added before dismissing the other to give a more seamless transition.
Hope this helps!
You can't present a view controller until the currently presented view controller has finished being dismissed. You won't know this has happened until the completion handler from your dismissal is called. Your mistake is that the completion handler is nil. Instead, provide a completion handler (in your first line), consisting of the remaining lines of your code. Thus, they will execute after the dismissal finishes.
[self dismissViewControllerAnimated:YES completion:^{
// ... the rest of your code goes in here ...
}];
When I try to present a UIImageViewController from the table view, the starting animation is a vertical cover, which I want, but when the controller gets dismissed, the animation is a Horizontal Flip. I tried [self presentViewController:self.imageController animated:YES completion:nil]; and [self.navigationController presentViewController:self.imageController animated:YES completion:nil]; but the dismiss animation is the same in both cases. When I remove the middle view controller (i.e just navigation controller with the tableview as its root), the dismiss animation is correct (cover vertical).
Anyone know how I can get the correct dismiss animation with the current storyboard configuration?
You can try this method:
[self.navigationController pushViewController:self.imageController animated:YES];
I'm working with SVWebViewController. When I present the view controller here
SVModalWebViewController *webViewController = [[SVModalWebViewController alloc] initWithAddress:address];
webViewController.webDelegate = self;
[self presentViewController:webViewController animated:YES completion:nil];
The view controller slides up from the bottom, as expected. However, when the view controller is dismissed, calling
[self dismissViewControllerAnimated:YES completion:nil];
The view controller simply disappears. No slide animation down. Any thoughts?
EDIT
It turns out a lot of presentation animations aren't displaying correctly in the application. Some pushes on the navigation controller aren't sliding in or sliding out (but some are). They just appear.
[self dismissViewControllerAnimated:YES completion:NULL];
This should be in SVModalWebViewController not SVWebViewController
EDIT: Instead of modally segueing to the SVWebViewController you should push:
SVWebViewController *webViewController = [[SVWebViewController alloc] initWithAddress:#"http://google.com"];
[self.navigationController pushViewController:webViewController animated:YES];
And instead of dismissing you should:
[self.navigationController popViewControllerAnimated:YES];
From SVWebViewController viewWillAppear::
SVWebViewController needs to be contained in a
UINavigationController. If you are presenting SVWebViewController
modally, use SVModalWebViewController instead.
Is your main view controller contained in a navigation controller? If not, this could possibly cause the other animation issues you're facing.
The dismissal should be from the displayed modalViewController.
It happens to me when the destination view controller loads a big picture or background
I try 2 ways to dismissed 2 viewcontrollers consecutively but only one of them got dismissed not the second one
method1
-(void) LoginDone:(NSNotification *)notif
{
[self dismissViewControllerAnimated:YES completion:NULL]; //previous viewcontroller
[self dismissViewControllerAnimated:YES completion:NULL]; //current viewcontroller
}
method2
-(void) LoginDone:(NSNotification *)notif
{
[self dismissViewControllerAnimated:YES completion:NULL];
[[NSNotificationCenter defaultCenter] postNotificationName:#"LoginDone2" object:nil];
}
-(void) LoginDone2:(NSNotification *)notif
{
[self dismissViewControllerAnimated:YES completion:NULL];
}
I need to find out a way to dismiss both the previous viewcontroller and current viewcontroller consecutively.
This is now an old question, but it seems to be exactly the problem I am having presently.
Here what I did:
[self.presentingViewController.presentingViewController
dismissViewControllerAnimated:YES completion:nil];
And it works for me. I hope it can be useful to someone.
By calling
[self dismissViewControllerAnimated:YES completion:NULL];
you are telling self to dismiss the view it presented. Telling twice the same self object to dismiss the view it presented, will not change the result. In other words self cannot represent the "current view" and the "previous view" at the same time as per your comment to the code. self is just a single controller representing a single view, either the current or the previous one.
To fix this, you should send the dismissViewControllerAnimated to self (that presented the top-most view, I assume) and to the other view controller object that presented the previous view.
In other words, I would expect something like this:
-(void) LoginDone:(NSNotification *)notif
{
[self dismissViewControllerAnimated:YES completion:NULL];
[self.previousController dismissViewControllerAnimated:YES completion:NULL];
}
Actually, you could send just one message to the second view controller and both views would be dismissed (source):
If you present several view controllers in succession, and thus build a stack of presented view controllers, calling this method on a view controller lower in the stack dismisses its immediate child view controller and all view controllers above that child on the stack. When this happens, only the top-most view is dismissed in an animated fashion; any intermediate view controllers are simply removed from the stack. The top-most view is dismissed using its modal transition style, which may differ from the styles used by other view controllers lower in the stack.
I know this is an old question but maybe somebody will look for solution on this issue so here it is:
-(void) closeModalViews
{
[previousVC dismissViewControllerAnimated:YES completion:^(void) {
[self dismissViewControllerAnimated:YES];
}];
}
I like JPetric's idea, but first you must dismiss the current view controller's view and only then can you dismiss the presenting view controller's view.
[self dismissViewControllerAnimated:NO completion:^(void) {
[self.presentingViewController dismissViewControllerAnimated:NO completion:nil];
}];
As far as I could understand you are trying something like below:
There are 2 view controllers.
You want both of them to be vanished.
Another controller comes in.
But the fact is only one controller is displayed, why you would need to dismiss 2 then?
You can use self.view.hidden=true; on the jumped viewcontrollers while animating back to the first viewcontroller. Using [self.presentingViewController dismiss...] is not working for me without hiding.
I want to know what is the different of them.
when I can call
[self dismissViewControllerAnimated:YES completion:nil];
and when I should call
[self.navigationController popViewControllerAnimated:YES];
according document of apple:
dismissViewControllerAnimated means
"Dismisses the view controller that was presented by the receiver."
But I always fail to dismiss view controller by this method.
-dismissViewControllerAnimated:completion:
Used to dismiss an UIViewController, which was presented by the method:
-presentViewController:animated:completion:.
-popViewControllerAnimated:
Method of UINavigationController is used to pop a controller shown by
-pushViewController:animated method of UINavigationController.
In the first case the view controller's view shows as a modal controller (usually from bottom to top), and the second case you are pushing a view controller in the navigation stack of UINavigationController.
your selected application is navigation based application means
[self.navigationController popViewControllerAnimated:YES];
your selected application is other than the navigation based application means
[self dismissViewControllerAnimated:YES completion:nil];
