iphone presentModalViewController - iphone

Question

I have an app, inside that an UIViewController is attached on the UIWindow.
on the view of UIViewController, i have added a button and a uiview_1 of size 100x80.
this uiview_1 contains another uiview_2 as subview of same size and this uiview_2 contains a UIImageView or a UIlable at runtime (both UIImageView and UIlable are userinteraction enabled)
now on the touch/click of UIImageView, i want to show a new view using presentModalViewController, the problem is the view is shown and using back button on the navigation bar i come to the previous/main screen.
here the problem come in picture, now i am unable to touch the button or the UIImageView.
both are not responding, but app is not crashed and nor frozen.
what is wrong in that?
Plz help in this...
----- EDIT:
Approach First:
SWVController *swvController = [[SWVController alloc] init];
UINavigationController *viewNavController = [[UINavigationController alloc] initWithRootViewController:swvController];
UIViewController *pushController = [[UIViewController alloc] init];
UIWindow *win = [[UIApplication sharedApplication] keyWindow];
[win addSubview:pushController.view];
[pushController presentModalViewController:viewNavController animated:YES];
In the swvController i have back button that calls the dismissModelViewController on click >> result is the Main screen ctrls are not responding to touch – sandy 3 hours ago
Second approach:
SWVController *swvController = [[SWVController alloc] init];
UINavigationController *viewNavController = [[UINavigationController alloc] initWithRootViewController:swvController];
UIViewController *pushController = [[UIViewController alloc] init];
[self addSubview:pushController.view];
[pushController presentModalViewController:viewNavController animated:YES];
In the swvController i have back button that calls the dismissModelViewController on click >> result is the swvController's back button on navbar is not responding – sandy 3 hours ago
3rd approach:
SWVController *swvController = [[SWVController alloc] init];
UINavigationController *viewNavController = [[UINavigationController alloc] initWithRootViewController:swvController];
SampleAppAppDelegate *appdel = [[UIApplication sharedApplication] delegate]; [appdel.viewController presentModalViewController:viewNavController animated:YES];
>> result is working fine, but the problem is i dont want to use SampleAppAppDelegate,i want to give my small Uiview (100x80) as a ctrl to other person , where my ctrl will not able to get the AppDelegate of thet app at run time. – sandy 3 hours ago

Answer 1

Call this method when you want to present the modal view controller:
- (IBAction)showInfo {
FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:#"FlipsideView" bundle:nil];
controller.delegate = self;
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:controller animated:YES];
[controller release];
}
Add this method to your self:
- (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller {
[self dismissModalViewControllerAnimated:YES];
}
Use a toolbar or other button and connect it to this method in your modal view controller:
- (IBAction)done {
[self.delegate flipsideViewControllerDidFinish:self];
}
All code comes from Apple.

How did you handled click/touch on UIImageView? TouchesBegan/Ended?
Try putting some logs (NSLog) and run your app in debug mode (put some breakpoints) to see if control reaches your action method...
Also, when you do presentModalViewController, you do not need to POP out with back button on navigation bar... you only need to dismissModelViewController to hide it.
