UIPopoverController presented from a UIButton does not hide? - iphone

I have a UIPopoverController that is presented from a button on my UIViewController but when I tap on any part of the view that is not the popover it is not hiding?
The buttons that present this popover are created dynamically, you'll see that referenced in the code below:
-(IBAction)showModifiers:(id)sender{
[self.popoverController dismissPopoverAnimated:YES];
UIView *theSuperview = self.view;
CGPoint touchPointInSuperview = [sender locationInView:theSuperview];
UIView *touchedView = [theSuperview hitTest:touchPointInSuperview withEvent:nil];
currentPopoverTag = [touchedView tag];
NSLog(#"Show Modifiers %i %i", [touchedView tag], currentPopoverTag);
RepZioCoreDataAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
if (appDelegate.popoverController)
[appDelegate.popoverController dismissPopoverAnimated:YES];
self.modifierListPopoverViewController = nil;
ModifierListCollection *collection = [self.modifierLists objectAtIndex:[touchedView tag]-100];
ModifierList *modifierList = [self getModifierList:collection.ModifierListID];
self.modifierListPopoverViewController =
[[[ModifierListPopoverViewController alloc] initWithModifierList:modifierList withManufacturerID: self.manufacturerID] autorelease];
self.modifierListPopoverViewController.delegate = self;
self.popoverController = [[[UIPopoverController alloc] initWithContentViewController:modifierListPopoverViewController] autorelease];
[self.popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}

I realize it's unlikely, but does your ModifierListPopoverViewController class set its modalInPopover property to YES? (the default is NO, which should give you the behavior you're looking for).

It seems that some view tackles the touch event.

didSelectAnnotationView for map is called only once in iphone sdk

I implemented a map view in my app.
I implemented a didselect annotation method.
In this method,i open a popover. It works fine. But when the popover is dismiss & try to click on annotation again, then method is not called more.
if i clicked other annotation except previously select annotation then method will called.
My code is follow:
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)aView {
ReadingDatabaseAppDelegate *appDelegate = (ReadingDatabaseAppDelegate *)[[UIApplication sharedApplication] delegate];
if([self isPad])
{
detailsView *popUp=[[detailsView alloc] initWithNibName:#"detailsView_ipad" bundle:nil];
popView = [[UIPopoverController alloc]initWithContentViewController:popUp];
popView.delegate =self;
[popView setPopoverContentSize:CGSizeMake(400, 400)];
AnnotationImageView *myLocationImage = (AnnotationImageView *)aView;
popUp.locationID = myLocationImage.locationID;
NSLog(#"%d",popUp.locationID);
popUp.list=listdata;
detView.fromMapView = TRUE;
if (appDelegate.preferenceRow == 1) {
detView.title = #"ATM Details";
popUp.isBranch = 0;
}
else {
detView.title = #"Branch Details";
popUp.isBranch = 1;
}
CGPoint annotationPoint = [mapView convertCoordinate:aView.annotation.coordinate toPointToView:mapView];
float boxDY=annotationPoint.y;
float boxDX=annotationPoint.x;
CGRect box = CGRectMake(boxDX,boxDY,5,5);
UILabel *displayLabel = [[UILabel alloc] initWithFrame:box];
[popView presentPopoverFromRect:displayLabel.frame inView:mapView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[displayLabel release];
}
}
** How can i solve this??**
When you dismiss your popover, deselect the annotation using -deselectAnnotation:animated:.

UIPopoverController disappears when ipad orientation changes

Popover appears properly when I click on button.
When orientation changes then it disappears & leave a black topbar.
Below is the reference image.
Can anyone suggest, why it is happening?
My Code:
EBFirstViewController *firstViewController = [[EBFirstViewController alloc]init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:firstViewController];
navigationController.delegate = self;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:navigationController];
self.popoverController = popover;
popoverController.delegate = self;
[popoverController setPopoverContentSize:CGSizeMake(320.0f, 527.0f)];
[popoverController presentPopoverFromRect:settingsBtn.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
For That following code help to solve your problem.
- (void)application:(UIApplication *)application willChangeStatusBarOrientation:(UIInterfaceOrientation)newStatusBarOrientation duration:(NSTimeInterval)duration {
// a cheat, so that we can dismiss all our popovers, if they're open.
if (ObjPopover) {
// if we're actually showing the menu, and not the about box, close out any active menu dialogs too
if (menuPopoverVC && menuPopoverVC == ObjPopover.contentViewController)
[menuPopoverVC.popoverController dismissPopoverAnimated:YES];
[menuPopoverPC dismissPopoverAnimated:YES];
menuPopoverPC = nil;
}
}
- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
// the user (not us) has dismissed the popover, let's cleanup.
ObjPopover = nil;
}

How can I see lastest subView after clicking popover embedded in NavigationView?

When click button, a popoverView embedded in NavigationView appear.
My code is as follows:
-(IBAction)myStuffPOP:(id)sender
{
if(myStuffListViewController ==nil)
{
myStuffListViewController = [[MyStuffListViewController alloc] init];
}
UINavigationController *navcontroller=[[[UINavigationController alloc] initWithRootViewController:myStuffListViewController] autorelease];
// Here we create popover controller.
mystuffPopoverView = [[UIPopoverController alloc] initWithContentViewController:navcontroller] ;
CGRect popoverRect = [self.view convertRect:[sender frame] fromView:[sender superview]];
popoverRect.size.width = MIN(popoverRect.size.width, 100);
popoverRect.size.height = 40;
[mystuffPopoverView presentPopoverFromRect:popoverRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
[navcontroller setNavigationBarHidden:NO];
}
In NavigationView of PopoverView :
1st subView ---> 2nd SubView ---> 3rd Subview
If I touch 3rd SubView, PopoverView disappears.
My Question is :
When I click button again, I wanna to see lastest View - 3rd SubView not 1st SubView.
Declare UINavigationController *navcontroller; in .h file
Create only onсe navcontroller with your root view controller,
in viewDidLoad method, for example.
- (void)viewDidLoad {
myStuffListViewController = [[MyStuffListViewController alloc] init];
navcontroller=[[UINavigationController alloc] initWithRootViewController:myStuffListViewController]; }
Show UIPopoverController with exist navigation stack
-(IBAction)myStuffPOP:(id)sender {
//Here we create popover controller.
mystuffPopoverView = [[UIPopoverController alloc] initWithContentViewController:navcontroller] ;
CGRect popoverRect = [self.view convertRect:[sender frame] fromView:[sender superview]];
popoverRect.size.width = MIN(popoverRect.size.width, 100);
popoverRect.size.height = 40;
[mystuffPopoverView presentPopoverFromRect:popoverRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp
animated:YES];
[navcontroller setNavigationBarHidden:NO]; }
Don't forget to release objects
- (void)dealloc {
[myStuffListViewController release];
[navcontroller release];
}
No need to create UINavigationController every time. Save it the same way as MyStuffListViewController
if ( myNavigationController == nil )
myNavigationController = [[[UINavigationController alloc] initWithRootViewController:myStuffListViewController] autorelease];

Show View before displaying thee UITabBar

I need to display a view before I display a tab based app and once the user taps a button the view goes away.
Any ideas?
here is some code that demonstrates the process. You can paste this code into the app delegate to run. Note, that this is spaghetti code, but I did it this way so you can see all the steps in one place. Normally, you will put parts of this code into its own view controller and classes.
this is in the appdelegate.. note that this is not completely tested for leaks and stuff.. its meant for an example.
#synthesize tabViewController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIWindow *w = [[UIWindow alloc]initWithFrame:[[UIScreen mainScreen] bounds]];;
self.window = w; //property defined in the .h file
[w release];
//create the tab bar controller
UITabBarController *tbc = [[UITabBarController alloc]init];
self.tabViewController = tbc;
[w addSubview:tbc.view];
//create the two tabs
NSMutableArray *a = [[NSMutableArray alloc]init];
//create the first viewcontroller
UIViewController *vca = [[UIViewController alloc]init];
vca.view.backgroundColor = [UIColor redColor];
vca.title = #"View A";
[a addObject:vca];
[vca release];
//and the second
UIViewController *vcb = [[UIViewController alloc]init];
vcb.view.backgroundColor = [UIColor blueColor];
vcb.title = #"View B";
[a addObject:vcb];
[vcb release];
//assign the viewcontrollers to the tabcontroller
tbc.viewControllers=a;
//release the array now that its retained by the tabcontroller
[a release];
[tbc release]; //tabbarcontroller is retained by our property
UIViewController *vcc = [[UIViewController alloc]init]; //this is the popup view
vcc.view.backgroundColor = [UIColor whiteColor];
UIButton *b = [UIButton buttonWithType:UIButtonTypeRoundedRect];
b.titleLabel.text = #"Click here";
[b addTarget:self action:#selector(buttonDismiss:) forControlEvents:UIControlEventTouchUpInside]; //hook into the buttons event
b.frame = CGRectMake(10, 10, 300, 40);
[vcc.view addSubview:b]; //add it to the popup view
[tbc presentModalViewController:vcc animated:YES];
[self.window makeKeyAndVisible];
return YES;
}
-(void) buttonDismiss:(UIButton *)sender
{
[self.tabViewController dismissModalViewControllerAnimated:YES];
}
Use a UIViewController. Present that controller as a modal view with the tab bar controller. Dismiss the view controller after that to hide it

Problem: Can´t pass a NSUInteger from one ViewController to the other anymore

I want pass a number from my ViewController to the the TweetViewController. Everything worked okay, I did it with NSUInteger as property (randomNumber and tweetNumber):
TweetViewController *Second = [[TweetViewController alloc] initWithNibName:nil bundle:nil];
Second.tweetNumber = randomNumber;
Second.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:Second animated:YES];
[Second release];
I have now changed my code because I did not want that only my TweetViewVontroller is loaded. I wanted a homescreenlike swipe between the Tweet- and InfoViewController. I use a SwitchViewController, which will be load instead of the TweetViewController. The SwitchViewController looks like this (window1/2 are UIViewController):
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0,0,320,460)];
UIView *contentView = [[UIView alloc] initWithFrame:CGRectMake(0,0,640,460)];
self.window1 = [TweetViewController alloc];
self.window2 = [InfoViewController alloc];
[contentView addSubview:self.window1.view];
CGRect f = self.window2.view.frame;
f.origin.x = 320;
self.window2.view.frame = f;
[contentView addSubview:self.window2.view];
[scrollView addSubview:contentView];
scrollView.contentSize = contentView.frame.size;
scrollView.pagingEnabled = YES;
self.view = scrollView;
[contentView release];
[scrollView release];
Now I can´t pass the number from the FirstViewController to the TweetViewController. Any Idea, how to solve the problem?
window1.tweetNumber = randomNumber;
If you want to update this every time the scrollview is scrolled, you might want to look into the UIScrollViewDelegate protocol. Specifically scrollViewWillBeginDragging:
