I have a ViewController with an UISearchController inside (with a table view on it). I've added this line on didSelectRowAtIndexPath::
[self dismissViewControllerAnimated:YES completion:nil];
For some reason, the viewController isn't being dismissed and instead, the keyboard is being dismissed (the searchController becomes inactive), to dismiss the viewController I have to reselect a cell on the table (and then didSelectRowAtIndexPath: is being called twice).
Any idea why is it happening?
Thank you!
This is probably happening because UISearchController inherits from UIViewController and therefore the controller being dismissed in didSelectRow is actually the search controller.
Perhaps simply try dismissing twice so that it removes the search controller followed by your custom view controller:
[self dismissViewControllerAnimated:YES completion:nil];
[self dismissViewControllerAnimated:YES completion:nil];
Try to resigning keyboard first and then dismiss vc.

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 am developing an app that as first viewcontroller has an UIViewController.
This controller pushes a NavigationViewController that contains other controllers.
Now I need to pop the RootViewController of the NavigationController to go back to the initial UIViewController.
I tried with
[self dismissViewControllerAnimated:YES completion:nil];
and the app crashes("Tread1:EXC_BAD_ACCESS(code=1, address= ......)").
I tried with
[self.navigationController popViewControllerAnimated:YES];
and nothing happens.
The initial UIViewController calls
[self performSegueWithIdentifier:#"MyIdentifier" sender:self];
In the UIBuilder the segue is of type "Show(e.g. Push)"
Then I have a NavigationViewcontroller that contains the RootViewController and another Viewcontroller.
What I am trying to achieve is to go back to the first viewcontroller (the one outside the navigationcontroller) from the RootViewController. So I should have the navigationcontroller there.
What am I missing?
Apparently I had a couple of GestureRecognizer still in place that were causing the crash of the app.
The right method was:
[self dismissViewControllerAnimated:YES completion:nil];
Here is my problem. I had a UITableViewcontroller to which UINavigation controller is Embedded. To UITableviewController I had Add screen and an edit screen. Add screen is working perfectly. When I click on the records on the table view cell it is able to redirect to the edit page (detailed view). When I hit on Submit button the page is not navigating to the tableview cell. Here is the below error.
Warning: Attempt to present on whose view is not in the window hierarchy!
Here is the code I was trying for navigation.
UINavigationController *questionnaireNavController = [self.storyboard instantiateViewControllerWithIdentifier:#"DLProjectsTasksubtasks"];
[questionnaireNavController setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
DLProjectsTasksubtasks *qvc = (DLProjectsTasksubtasks *)[questionnaireNavController topViewController];
[qvc.tableView reloadData];
[self presentViewController:questionnaireNavController animated:YES completion:nil];
[self dismissViewControllerAnimated:YES completion:nil];
Between I was using a Segue for transfering the data from tableview data to Edit Screen
I think your segue is being pushed on the navigation controller rather than being presented modally. So you have two options, either change the segue in your storyboard to be modal and use the dismissViewControllerAnimated:YES completion: or keep it the way it is and use popViewControllerAnimated: on your navigation controller.
[self.navigationController popViewControllerAnimated:YES];
For passing the data to the previous page you can either pass a reference of the previous view controller OR accessing it through your navigationController.viewControllers. Index n-2 will be your previous view controller (n is the count of viewControllers).
Suppose i have 3 view controllers. I initiate vc1 in vc0 and then vc2 in vc1. Now i want vc2 to be dismissed and after that only vc0 should be shown behind it. How's that possible? I read something about delegate declaration. But couldn't understand.
I have UISegmentcontrol where i'm displaying a controller from storyboard like - vc0 = [self.storyboard instantiateViewControllerWithIdentifier=#"vc0"]; and making it a subview of it [self.view addSubview:vc0.view]; Vc0 is a tableView, which has a detailcontroller to be presented. When i tap on a cell, it shows detailview, but actual segmentcontrol.view is lost when detailview is dismissed.
An example would be awesome.
PS: I'm not using segue for the viewControllers. Instead, i'm using presentModalViewController and dismissModalViewController.
In iOS 5 you need to do
[self.presentingViewController.presentingViewController dismissModalViewControllerAnimated:YES]
As of iOS 6 dismissModalViewControllerAnimated: is deprecated.
You need to call
[self.presentingViewController.presentingViewController dismissViewControllerAnimated:YES completion:^{ // Do something on completion}]
//If you want to perform something while going through views or other wise keep completion to nil as shown in below code.
or
[self.presentingViewController.presentingViewController dismissViewControllerAnimated:YES completion:nil];
or
[self.parentViewController.parentViewController dismissModalViewControllerAnimated:YES];
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.
