I am having a little problem -
(BTW i have looked on
How can I present a modal view controller after selecting a contact?
but it didnt help me)
Basically i want to let the user select a contact using the - peoplePickerNavigationController. after the selection i want to presentModalViewController that will use the personRef data.
i can see that the "add person" method get called but the iphone does not present the view.
UPDATE - It works if i cancel the animation in the Dismiss dismissModalViewControllerAnimated and in the presentModalViewController, but then it looks pretty ugly.
this is the function called after the user selects the contact -
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)personRef {
TempREcordId = ABRecordGetRecordID(personRef);
BOOL hasDeleteDate = [GlobalFunctions CheckToSeeIfInHiBye:TempREcordId];
if (hasDeleteDate) {
[GlobalFunctions alert:NSLocalizedString(#"", #"") ];
}else{
[self addCustomValuesAfterSelection];
[self dismissModalViewControllerAnimated:YES];
}
return NO;
}
this is the function called but still the view is not presenting -
- (void)addPerson {
NSLog(#"#2");
AddViewController *addViewController = [[AddViewController alloc] initWithStyle:UITableViewStyleGrouped];
addViewController.delegate = self;
// Create a new managed object context for the new book -- set its persistent store coordinator to the same as that from the fetched results controller's context.
NSManagedObjectContext *addingContext = [[NSManagedObjectContext alloc] init];
self.addingManagedObjectContext = addingContext;
[addingContext release];
[addingManagedObjectContext setPersistentStoreCoordinator:[[fetchedResultsController managedObjectContext] persistentStoreCoordinator]];
addViewController.person = (Person *)[NSEntityDescription insertNewObjectForEntityForName:#"Person" inManagedObjectContext:addingContext];
addViewController.hiByeGroupId = [dataSource hibyeGroupId];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:addViewController];
[self.navigationController presentModalViewController:navController animated:YES];
[addViewController release];
[navController release];
}
thank you very much.
Just don't dismiss the people picker and present your controller modally on top of it. If you afterwards dismiss your controller at some point dismiss the people picker instead (from the caller/parent) and your ViewController will be dismissed too.
From the Apple Docs:
dismissModalViewControllerAnimated: …
If you present several modal view controllers in succession, and thus build a stack of modal 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.
Although by picking a person, the picker dismisses, the key is to dismiss it yourself in the delegate callback, after picking a person and than present your controller
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person {
[self.navigationController dismissViewControllerAnimated:YES completion:^{
ContactDetailViewController * vc = [[ContactDetailViewController alloc] initWithWithABRecord:person];
vc.delegate = self;
UINavigationController * nc = [[UINavigationController alloc] initWithRootViewController:vc];
[self.navigationController presentViewController:nc animated:YES completion:^{
}];
}];
}
I suppose you just have to wait until the people picker disappeared by finishing its animation which it indicates by calling viewDidDisappear. If you override and hook up in there, you should be save to present your modal controller.

When I push cancel button in the third view, I want to go back to the first view directly.
I also want to remove the second view.
How can I do that?
This is the code.
// this part is in the first view.
self.second = [SecondController alloc] init];
[self.view addSubview:second.view];
// this part is in the second view.
ThirdController *thirdController = [[ThirdController alloc] initWithStyle:UITableViewStyleGrouped];
self.navigationController = [UINavigationController alloc] initWithRootViewController:thirdController];
[self.view addSubview:navigationController.view];
// this part is in the third view.
- (void)cancel {
[self.view removeFromSuperview]; // this only goes to the second view.
}
EDIT:
Can I use popToViewController in called contoller? My app crashes.
I thought popToViewController can be used only in calling controller.
And popToViewController is used when it was pushed.
I did add not push.
[self.navigationController popToViewController:[[self.navigationController viewControllers] objectAtIndex:0] animated:YES];
popToViewController:animated: is a UINavigationController method that you use when popping view controllers off the navigation controller stack. It doesn't fit for this scenario.
This user is adding subviews, not pushing them on a navigation controller stack.
As a note, it appears as a matter of design you should be using a navigation controller with the first view as the root controller, then the second pushed on the stack, and the third pushed on the stack. Then all you have to do is [self.navigationController popToRootViewControllerAnimated:YES].
I think this will work if you want to keep your current architecture:
// this part is in the third view.
- (void)cancel {
// remove the second view (self.view.superview) from the first view
[self.view.superview removeFromSuperView];
// can't recall, possibly you still need to remove the third view, but i think removing the superview will do it.
// [self.view removeFromSuperView];
}
If you prefer to try the UINavigationController route, then the easiest path is to create a new project in Xcode and select the type for a Navigation-Based Application or a Master-Detail Application. This will create a UINavigationController in a nib and add it to your window. You can then set the root view controller in Interface Builder to your FirstViewController class.
If you prefer to create the UINavigationController in code, then that is also possible. I show that below, along with the rest of the code you need, regardless of whether you create your UINavigationController in a nib in IB or in code.
I also recommend reading the View Controller Programming Guide for iOS.
In your app delegate or some other code:
-(void)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions [
// I would recommend setting up the UINavigationController and FirstViewController as IBOutlets in your nib, but it can be done in code.
FirstViewController* fvc = [[FirstViewController alloc] initWithNibName:#"FirstView" bundle:nil];
UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:fvc];
[window addSubView:navController.view];
[window makeKeyAndVisible];
[fvc release];
[navController release];
}
In the first view controller:
SecondViewController* svc = [[SecondViewController alloc] initWithNibName:#"SecondView" bundle:nil];
[self.navigationController pushViewController:svc animated:YES];
[svc release];
In the second view controller:
ThirdViewController* tvc = [[ThirdViewController alloc] initWithNibName:#"ThirdView" bundle:nil];
[self.navigationController pushViewController:tvc animated:YES];
[tvc release];
In the third view controller:
-(void)cancel {
// returns to the first view controller
[self.navigationController popToRootViewControllerAnimated:YES];
}
Use
- (NSArray *)popToViewController:(UIViewController *)viewController animated:(BOOL)animated
to go back to a specific view controller.
Try this:
[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:1] animated:YES];
This will pop to the view at index 1. Hope that Helps!
// this part is in the third view.
- (void)cancel {
self.first = [SecondController alloc] init];
[self.view addSubview:second.view];
}
And I think if you have you don't need to be worried about removing beneath view, later these will removed.
Im presenting and dismissing a Modal View Controller. I use delegation so I dismiss the modalView at the Parent.
- (void)launchDrawingSection{
drawingSectionViewController = [[DrawingSectionViewController alloc] init];
drawingSectionViewController.modalTransitionStyle = UIViewAnimationTransitionFlipFromLeft;
drawingSectionViewController.drawingModalDelegate = self;
[self presentModalViewController:drawingSectionViewController animated:YES];
}
- (void)didDismissDrawingModalView{
NSLog(#"didDismissDrawingModalView");
[drawingSectionViewController release];
[self dismissModalViewControllerAnimated:YES];
}
The app crashes after the dealloc method in the ModalView gets called.
Am I doing something wrong with the way I present and dismiss a Modal View Controller? Any idea?
Don't release before dismiss.
- (void)launchDrawingSection{
drawingSectionViewController = [[DrawingSectionViewController alloc] init];
drawingSectionViewController.modalTransitionStyle = UIViewAnimationTransitionFlipFromLeft;
drawingSectionViewController.drawingModalDelegate = self;
[self presentModalViewController:drawingSectionViewController animated:YES];
[drawingSectionViewController release];
}
- (void)didDismissDrawingModalView{
NSLog(#"didDismissDrawingModalView");
[self dismissModalViewControllerAnimated:YES];
}
Your fundamentals of Modal View Controller is not clear.
If you are using delegate protocols only to inform the drawing sections's parent control to dismiss the drawing section controller, then this is something useless. Because, the following thing does your job without use of delegates.
// Present drawing section.
- (void)launchDrawingSection{
drawingSectionViewController = [[DrawingSectionViewController alloc] init];
drawingSectionViewController.modalTransitionStyle = UIViewAnimationTransitionFlipFromLeft;
drawingSectionViewController.drawingModalDelegate = self;
[self presentModalViewController:drawingSectionViewController animated:YES];
[drawingSectionViewController release];
}
// (Put this in Drawing Section View Controller). This function dismisses drawing section.
- (void)dismissActionEvent{
// Drawing section view controller is asking its parent to dismiss it.
[self.parentViewController dismissModalViewControllerAnimated:YES];
}
To understand clearly how presenting and dismissing modal view controller's work, refer to my answer here
I have a main window that pops a modal view controller. When done in this modal view controller, it returns to the main window then dismisses itself.
Then the main windows pops a new Modal view controller with animated=YES.
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.
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];
}
What may I do ?
I don't want to catch anything in view....Disapear...
Why does the dismiss colides as they are not called from the same navigation controller ?
The reason is likely the animation when you dismiss it. Try showing the second modal window using the performSelector:withObject:afterDelay:, a method inherited from NSObject. Reference here.
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.
I have an "add Contact" button which when on iPhone I present a navigation controller with root view controller of an ABNewPersonController modally.
If on iPad I have got a popover which I can display with the new person controller inside - nice.
The problem comes when trying to dismiss.
I can dismiss the popover when touching done or cancel within my implementation of didCompleteWithNewPerson using;
if(self.popoverController != nil)
[popoverController dismissPopoverAnimated:YES];
However, this doesn't dismiss when touching outside the popover.
I've returned YES for my popoverControllerShouldDismissPopover method and set the delegate of my popover to this. I've put an NSLOG inside this method and it's not dropping in there - Am I missing something?
Does anyone know how to dismiss the popover when touching outside?
Update - More Code
-(IBAction)contactsClicked:(id) sender{
ABNewPersonViewController *newPersonView = [[ABNewPersonViewController alloc] init];
[newPersonView setNewPersonViewDelegate:self];
[newPersonView setDisplayedPerson:newPerson];
UINavigationController *addContactNavController = [[UINavigationController alloc] initWithRootViewController:newPersonView];
[newPersonView release];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
if(self.popoverController == nil){
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:addContactNavController];
self.popoverController = popover;
self.popoverController.delegate = self;
[popover release];
}
CGRect frame = [sender frame];
[popoverController presentPopoverFromRect:frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES];
} else {
[self presentModalViewController:addContactNavController animated:YES];
[addContactNavController release];
}
}
-(void)unknownPersonViewController:(ABUnknownPersonViewController *)unknownPersonView didResolveToPerson:(ABRecordRef)person{
[self dismissModalViewControllerAnimated:YES];
}
-(void)newPersonViewController:(ABNewPersonViewController *)newPersonViewController didCompleteWithNewPerson:(ABRecordRef)person {
NSLog(#"DONE OR CANCEL clicked!!!!"); //prints
if (self.popoverController != nil) {
[popoverController dismissPopoverAnimated:YES];
}
[self dismissModalViewControllerAnimated:YES];
}
The Done and Cancel buttons of the new person controller work, dismissing the controller and the popover (when running on iPad). I guess this means the delegate for the ABNewPersonViewController is implemented correctly. (?)
I'm guessing that I may be confusing the issue by having multiple controllers and my popover delegate method is getting hidden or something?
Thanks in advance
EDIT - Delegate method
-(BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)thePopoverController{
NSLog(#"clicked outside the popover");//never prints
return YES;
}
From the docs:
Taps inside the popover window do not automatically cause the popover to be dismissed. Your view and view controller code must handle actions and events inside the popover explicitly and call the dismissPopoverAnimated: method as needed.
You should use the popover delegate methods –popoverControllerShouldDismissPopover: to listen for when it's about to be dismissed and do your saving etc. there.
Also, you should use self not this.
