I've unsuccessfully tried:
1. [self dismissViewControllerAnimated:YES completion:Nil];
2. [[self parentViewController] dismissViewControllerAnimated:YES
completion:Nil];
3. //from the parent view controller using a delegate
-(void)closeReplaceController
{
DLog(#"closeReplaceController");
[self dismissViewControllerAnimated:YES completion:Nil];
}
I would try something like this:
-(void)killPresentingView
{
UIViewController *vc = [self presentingViewController];
[vc dismissViewControllerAnimated:YES completion:nil];
}
And see what happens. If I understood you right, this should work.

I have a web view controller, suppose A
The weviewcontrollerA contain 2 button at top ButtonA and ButtonB
Now my question is
From Another ViewControllerX i load weviewcontrollerA by passing URL as parameter, to load www.google.com in the webviewControllerA view.
for example :
-(IBAction)loadweviewcontrollerA
{
weviewcontrollerA *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"weviewcontrollerA"];
vc.urltoload=#"https://wwww.google.com";
[self presentViewController:vc animated:NO completion:nil];
}
Now in webviewcontrollerA , i have to reload the same view again with below condition
1) Reloading the viewDidload (or present the same class again) is compulsory as i have to pass some Parameter in the uRL also as HTTPRequest with the weburl
2) how to dismiss webviewcontrollerA , and then suddenly load it again without user known it.
how i jump,below code work, but user see ViewControllerX and the it load again, how i skip that user not visible the ViewControllerX or it load so quickly without user notice
-(IBAction)ButtonA
{
[self dismissViewControllerAnimated:NO
completion:^{
weviewcontrollerA *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"weviewcontrollerA"];
vc.urltoload=#"https://wwww.facebook.com";
UIViewController *topvc=[self topMostController];
[topvc presentViewController:vc animated:NO completion:nil];
//[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:vc animated:YES completion:nil];
}];
-(IBAction)ButtonG
{
[self dismissViewControllerAnimated:NO
completion:^{
weviewcontrollerA *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"weviewcontrollerA"];
vc.urltoload=#"https://wwww.twitter.com";
UIViewController *topvc=[self topMostController];
[topvc presentViewController:vc animated:NO completion:nil];
//[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:vc animated:YES completion:nil];
}];
//----------- END OF MORE INFO POP UP VIEW---------------
- (UIViewController*) topMostController
{
UIViewController *topController = [UIApplication sharedApplication].keyWindow.rootViewController;
while (topController.presentedViewController) {
topController = topController.presentedViewController;
}
return topController;
}
I'm doing an ios project without using any story board and xibs.
Here I've come out one problem on presenting my UIViewController.
Here is the senario:
My RootViewController has 2 UIButton's that can present ViewControllerA and ViewControllerB when being pressed.
-(IBAction)btnAclicked:(id)sender{
[self.navigationController presentViewController:ViewControllerA];
}
-(IBAction)btnBclicked:(id)sender{
[self.navigationController presentViewController:ViewControllerB];
}
And now inside ViewControllerA
I have a button to presentViewContollerB as well, and I want only the RootViewController to be displayed when I dismiss ViewContollerB.
In order to do this, I need to dismiss ViewControllerA first then presentViewControllerB. I know there is ways like using delegate to make it works, but I just want to know if there is any easier way to do this.
To be emphasised is that I want to use presentViewController only, not pushViewController. Thanks
I have an answer for your question,just do the following code,
in RootViewController.m
- (IBAction)gotoViewA:(id)sender
{
ViewControllerA *viewControllerA = [[ViewControllerA alloc]initWithNibName:#"ViewControllerA" bundle:nil];
[self presentViewController:viewControllerA animated:YES completion:nil];
}
- (IBAction)gotoViewB:(id)sender
{
ViewControllerB *viewControllerB = [[ViewControllerB alloc]initWithNibName:#"ViewControllerB" bundle:nil];
[self presentViewController:viewControllerB animated:YES completion:nil];
}
in ViewControllerA.m
- (IBAction)actionBackFromA:(id)sender
{
[self dismissViewControllerAnimated:YES completion:nil];
}
in ViewControllerB.m
- (IBAction)actionBackFromB:(id)sender
{
[self dismissViewControllerAnimated:YES completion:nil];
}
Use the completion block of presentviewcontroller,viz will executed first
[self presentViewController:goTo_B animated:YES completion:^{
//Dismiss A
[self dismissViewControllerAnimated:YES completion:nil];
}];
If this does not work,write dismiss and just after it present your new controller
[self dismissViewControllerAnimated:YES completion:nil];
[self.view.window.rootViewController presentViewController:goTo_B animated:YES completion:^{ }];
There's another way out, but i don't know whether its appropriate or not.
Create a property of type View Controller A in view controller B.
While presenting view controller B, assign an instance of View Controller A to the property in view Controller B.
[self presentViewController:goTo_B animated:YES completion:^{
goTo_B.propertyOfViewControllerA = self;
}];
After that while dismissing view controller B you can do the either of the two:
[self dismissViewControllerAnimated:YES completion:nil];
[propertyOfViewControllerA dismissViewControllerAnimated:YES completion:nil]
or
[self dismissViewControllerAnimated:YES completion:^{
[propertyOfViewControllerA dismissViewControllerAnimated:YES completion:nil]
}];
I have been developing an iPhone app and have come across a few issues. I do not have a storyboard in my app and have nothing in my xibs. I have initialised and set everything up through code. When I go to the GameViewController from my main viewcontroller everything is fine, however when I come back through my back button I get this issue:
Presenting view controllers on detached view controllers is discouraged .
When I re-arrive to the main view controller, there are little changes such as the view changing before its supposed to. Here is the code for the button on my
GameViewController *game = [[GameViewController alloc] initWithNibName:nil bundle:Nil];
[self dismissViewControllerAnimated:YES completion:NULL];
[self presentViewController:game animated:YES completion:NULL];
Here is the code for the back button:
ViewController *home = [[ViewController alloc] initWithNibName:nil bundle:nil];
[self dismissViewControllerAnimated:YES completion:NULL];
[self presentViewController:home animated:NO completion:NULL];
If anyone can help me to see what I am doing wrong that would be great.
You can not present home view controller from self because it is already dismissed. You should change
[self dismissViewControllerAnimated:YES completion:NULL];
[self presentViewController:home animated:NO completion:NULL];
to
UIViewController *parentViewController = self.presentingViewController;
[self dismissViewControllerAnimated:YES completion:^
{
[parentViewController presentViewController:home animated:NO completion:nil];
}];
I'm fairly new to this, so bear with me. I have 2 errors left to fix in my code. In both cases my instance methods are not found:
-(IBAction)goFlipSide {
NSLog(#"goFlipSide has been called:");
FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:#"FlipsideViewController" bundle:nil];
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:controller animated:YES];
[controller release];
}
- (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller {
[self dismissViewControllerAnimated:YES];
//This method gets fired when the user clicks done on the modal FlipsideViewController. This is different
//than the viewWillAppear.
self.navigationController.navigationBarHidden = TRUE;
/*
if (self.goViewSuccess == TRUE) {
//if the goViewSuccess boolean is set to YES - then we can load the load the goViewController
NSLog(#"goViewSuccess is YES");
[self loadGoViewController];
}
*/
}
Both instance methods not found are: presentViewController: and dismissViewControllerAnimated:.
What class is self? Those methods are only found on UIViewController. The full selectors are:
presentViewController:animated:completion:
dismissViewControllerAnimated:completion:
Try adding the completion block argument.
The code is supposed to be this
[self dismissViewControllerAnimated:YES completion:nil];
or if you want something when its done,
[self dismissViewControllerAnimated:YES completion:^{
//do stuff
}];
And for the other one
[self presentViewController:controller animated:YES completion:nil];
MainMenuViewController presents BonusViewController modally. I want to Dismiss BonusViewController then display a new BonusViewController, effectively "resetting" BonusViewController.
Im using notifications to call this method in MainMenuViewController
-(void)resetBonus{
[self dismissViewControllerAnimated:YES completion:nil];
[self presentViewController: BonusViewController animated:NO completion:nil];
}
I expected BonusViewController to be auto-detected as I was typing it in the presentViewController call above but it was not and none of my viewControllers show up as I type which Im assuming means im doing this all wrong. Do I have to initialize the VC or allocate it before I can present it like this? Or can I even do this at all since im using storyboards?
I also tried this though I believe this method is deprecated
-(void)resetBonus{
[self dismissModalViewControllerAnimated:YES];
[self presentModalViewController: BonusViewController animated:NO ];
}
Did what Sumanth suggested but I get this message now:
so now I m doing :
#import "BonusViewController.h
....
-(void)resetBonus
{
BonusViewController *bonus = [[BonusViewController alloc]init];
[self dismissModalViewControllerAnimated:NO];
[self presentModalViewController: bonus animated:NO ];
}
the errors are all gone but when BonusViewController is presented the display is solid black, i can hear the sounds going but cant see anything on the screen
you should allocate and initialize the viewcontroller and present that using presentModalViewController write like this
BonusViewController *bonus = [[BonusViewController alloc]init];
[self dismissModalViewControllerAnimated:YES];
[self presentModalViewController: bonus animated:NO ];
Also dont forget to write #import "BonusViewController.h" in .h file
BonusViewController *objBonus = [[BonusViewController alloc]init];
[self dismissViewControllerAnimated:YES completion:NULL];
[self presentViewController:objBonus animated:YES completion:NULL];
You need to create and object of the viewcontroller and you are directly passing the viewcontroller which is not possible
#import "BonusViewController.h"
-(void)resetBonus
{
BonusViewController *BonusViewController = [[BonusViewController alloc]init];
[self dismissViewControllerAnimated:NO completion:nil];
[self presentViewController: BonusViewController animated:NO completion:nil];
}
Set Both of animated is NO
EDIT : #import "BonusViewController.h"
Im sure the answers given were correct but I could not get them to work properly. For some reason BonusViewController seems to be displayed as I can hear the sounds going but the screen is black and nothing is displayed visually.
I ended up doing the below for now in the intrest of time but this isnt the smooth effect I was really going for.
I have to re-visit this when I have more time to figure out a better way to do it.
-(void)endBonus
{
[self dismissViewControllerAnimated:NO completion:^{
[self performSelector:#selector(resetBonus) withObject:nil afterDelay:1];
}];
}
-(void)resetBonus
{
[self performSegueWithIdentifier: #"segueToBonus" sender: self];
}
