I founded that the problem is the place where I'm calling the showNextView. I have another interface webService where i communicate with server and parse xml. When the parsing is finished with method parserDidEndDocument I'm calling the delegate method where is changed the view and show modal view. But when i call all that methods it will return to endDocument and xmlParseChunk and so on. It looks like the parserDidEndDocument is not realy the last method and somehow it mess with navigationcontroler. When i call the method for showig nextView with button it works.
The code which is working on button. In delegate method called from parserDidEndDocument is not working correct.
-(void)showNextView
{
UIViewController *nextView = [self.storyboard instantiateViewControllerWithIdentifier:#"vcTrabantInfo"];
[[nextView navigationController] setNavigationBarHidden:NO animated:NO];
[[self navigationController] pushViewController:nextView animated:YES];
UIViewController *picker = [[UIViewController alloc] init];
[picker setModalPresentationStyle:UIModalPresentationFormSheet];
[[self navigationController] presentModalViewController:picker animated:YES];
}
As usualy the problem was between keyboard and seat. The problem was that my modal views haven't been dismissed before i call another modal view :). So keep in mind that all is done in viewDidDisappear.

I used button action to to pop sub view sing below code;
- (IBAction)pickerUpBtn:(id)sender {
PickerPopUpController *screen = [[PickerPopUpController alloc]initWithNibName:#"PickerPopUpController" bundle:Nil];
[self.view addSubview:screen.view];
[self presentModalViewController:screen animated:YES];
}
after i need to go previous window; So i used another button action for it and add bellow code inside action
PickerViewController *screen = [[PickerViewController alloc]initWithNibName:#"PickerViewController" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:screen animated:YES];
But It does not navigate to previous view . How could i do it ??
to go back,
do
[self dismissModalViewControllerAnimated:YES]
You need to put only that single code in the Button action..No need of making object of parentViewController.
ie,
-(IBAction)btnaction:(id)sender{
[self dismissModalViewControllerAnimated:YES];
}
You need to add cancel and done for your ViewController which is present modely to come back to parent view Controller.
After implementing the Cancel button, you have to dismiss your viewcontroller in the action function of Cancel button using the dismissModalViewControllerAnimated function
[self dismissModalViewControllerAnimated:YES];
For push view controller, you can do like below,
PickerViewController *screen = [[PickerViewController alloc]initWithNibName:#"PickerViewController" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:screen animated:YES];
Then for go back, you have to add one button in "Screen" view controller and it's click event you have to write below code,
[self.navigationController popViewControllerAnimated:YES];
Hope, it would be helpful.
Let me know in case of any difficulty.
If you are using the method "presentmodelviewcontroller" then you have to write below line in button click.
[self dismissModalViewControllerAnimated:YES];
I have a parent view that opens a child view like so:
ChildViewController *child = [[ChildViewController alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:child animated:YES];
Which works perfectly fine. I need to dismiss the child view from the parent view but when I do that, nothing happens. Is it because the parent view stops all of its processes when I open the child view? Or is it my code: [child dismissModalViewControllerAnimated:YES]; ? Thanks
dismissModalViewControllerAnimated: has to be called on the same object that presentModalViewController:animated: was called on.
In your example, it would need to be [self dismissModalViewControllerAnimated:YES];
If you were dismissing from inside the controller being displayed modally, it would be as #James Bedford described [[self parentViewController] dismissModalViewControllerAnimated:YES];
Where are you calling [child dismissModalViewControllerAnimated:YES];? Is this line of code ever being reached?
You could add a target/action to one of your UIControls within your ChildViewController class which uses the inherited parentViewController property to dismiss itself as follows:
[[self parentViewController] dismissModalViewControllerAnimated:YES];
let me explain you my problem:
I have an UIViewController with 2 UIViews.
I have a button in one of my UIView and i call a methode from my UIViewController.
[controller actionMainSettings];
And this is the methode:
-(void)actionMainSettings{
MainSettings *mainController = [[MainSettings alloc] initWithNibName:#"MainSettings" bundle:nil];
[self.navigationController pushViewController:mainController animated:YES];
[[self navigationController] setNavigationBarHidden:YES animated:NO];
[mainController release];
}
MainSettings is an UIVewController...
and nothing happen...
When i put my button in my UIVIewController ([self.view addSubview:buttonSettings];) it's ok but i want to put it in another UIView.
Can someone explain me what happen?
thx
I am not very sure about this but you could try super.navigationController instead of self.
Also, from the look of your code, I would assume it's a settings view. I would recommend that you use [self presentModalView:yourView animated:YES]. You can look at the UIView documentation for a range of animations.
I'm searching a way to be able to display one modal view controller after another one, and make the second appear while the first is disapearing.
The problem is that the dismiss call that is done inside the first modalviewcontroller applies to both and SecondController is never shown.
Putting the first dismiss before or after the parent call does not change anything.
If first dismiss is set wih animate= NO, everything works fine. But I need the animation.
I planned to do that this way, but the problem is that the dismiss call that is done inside the first modalviewcontroller applies to both and SecondController is never shown.
I don't understand why because each modal view has its own navigationcontrollers, so they shouldn't collide.
I tried another way by showing the second modal view with a NSTimer after 0.5 sec, but it's not satisfying : the second appears when the first has completely disapeared. Not smooth at all... If I set the delay less than 0.5 sec, the second modal view never shows up. And using such a timer to make this does not seem to be a good way of coding.
Main.m
- (void) entry {
FirstController *nextWindow = [[FirstController alloc] initWithNibName:#"theNIB" bundle:nil];
nextWindow.caller = self;
UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:nextWindow];
[self.navigationController presentModalViewController:navController animated:YES];
[nextWindow release];
[navController release];
}
- (void) thingsDoneInFirstModalController:(OBJECT)returnValue retval2:(OBJECT2)returnValue2 {
[self display2ndController];
}
- (void) display2ndController {
SecondController *nextWindow;
nextWindow = [[SecondController alloc] initWithNibName:#"NIB2" bundle:nil];
UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:nextWindow];
[self.navigationController presentModalViewController:navController animated:YES];
[navController release];
[nextWindow release];
}
1st ModalViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self.navigationController dismissModalViewControllerAnimated:YES];
[self.caller thingsDoneInFirstModalController:theResult retval2:someMoreResult];
}
Do you know a way to make this possible (make the second view appears while the first one is disappearing), with some code for example ?
Thank you.
Try creating some dummy ViewController, and present your second one using it.
I have the following code where I display a view controller within a navigation controller.
Just for the test I display it for 3 seconds and then dismiss it.
What is happening is that it disappearing - and then reappearing after a second or so.
What am I doign wrong?
- (void) test
{
[myNavCtrl dismissModalViewControllerAnimated:YES];
}
- (void) viewDidAppear:(BOOL)animated
{
MyViewController *ctrl = [[MyViewController alloc] init];
[ctrl setDelegate:self];
myNavCtrl = [[UINavigationController alloc] initWithRootViewController:ctrl];
[myNavCtrl setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentModalViewController:myNavCtrl animated:NO];
[ctrl release];
[myNavCtrl release];
[self performSelector:#selector(test) withObject:nil afterDelay:3];
}
The viewWillAppear method is called every time the controller's view appears so you've created a loop. The view appears, it calls the modal view which covers the calling view. When the modal view disappears, the calling view controller's viewWillAppear gets called again. Lather, rinse, repeat.
