In my app, I have my main view and when i click a button, a UIPopoverController is shown over my main view (not fullscreen so i still see the view behind) containing a UITableView. When I click one of the tableview cells, I want to show a custom view centered on screen (simple view informing the user that the app is processing) that will fade in and fade out during a specific amount of time.
The problem is that my custom view always appears UNDER the UIPopover...I tried all I can think of, bringSubviewToFront etc...Nothing works... I also tried to wrap my custom view in a UIViewController and use [mainView presentViewController:myCustomView ...] but when I do that the main view disappear
Someone can help?
Thx
Thx Ole Begemann, this question was indeed a duplicate.
Although, the solution to my problem is not to subclass UIWindow but to add my UIView to the key UIWindow :
NSArray * windows = [[UIApplication sharedApplication] windows];
UIWindow* win0 = [windows objectAtIndex:0];
[win0 addSubview:loadingView];
[win0 bringSubviewToFront:loadingWindow];

I have added a ViewvController(B) as subview on ViewController(A). In ViewController A(SuperView) UIModelPresentationFullScreen working fine. But when am calling UIModelPresentationFull in ViewController B(SubView) it modelview showing in Portrait mode and that is also not fully viewed. How to solve this problem. Can any one help me please. I have tried 2 days.
This is what I tried in both the superview and subview...
picFBCapture *fbCapt = [[picFBCapture alloc] init];
//[self.navigationController pushViewController:fbCapt animated:YES];
//fbCapt.modalPresentationStyle = UIModalTransitionStyleFlipHorizontal;
fbCapt.modalTransitionStyle = UIModalPresentationFullScreen;
[self presentModalViewController:fbCapt animated:NO];
[fbCapt release];
Thanks in advance..
The problem is that if you add a view controller as a subview it's not connected to the view controller hierarchy and thus certain things doesn't work. You should avoid adding view controllers as subviews whenever possible, since this is not how Apple intend view controllers to be used, but sometimes it can't be avoided.
If this is one of those cases when it can't be avoided you should save a reference to view controller A in view controller B and then call presentModalViewController: on view controller A (that is connected to the view controller hierarchy) instead of self (view controller B, that isn't connected).
EDIT: In controller A you probably have code looking something like:
[self.view addSubview:controllerB.view];
In conjunction to this line add:
controllerB.controllerA = self;
I hope you know how to create properties, but if not here's a hint:
#property (nonatomic, assign) UIViewController *controllerA;
The rest you should be able to figure out using Google and the documentation.
You will have to handle viewController B's view in landscape by yourself. Since viewController B has been added as a subview, its view controller will not be handling its landscape orientation. The UIModalPresentationFullScreen style (landscape and portrait) will work only if viewController B is shown, ie not as subview but as a full view itself.
I am trying to programmatically add a Navigation Controller to my View based Application. This is the code I am using (this code gets called after a button press in a view controller):
MainMenu *control = [[MainMenu alloc] initWithNibName: #"MainMenu" bundle: nil];
UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController: control];
[self.view addSubview:navControl.view];
[control release];
That works, but this ends up happening:
Notice the odd margin above the Navigation control.... My View controller that I am adding the Navigation Controller to has a gray background which you can see.
Any ideas??
If you have a better way of adding a Navigation Controller to a View based Application I am very open to suggestions!
Thank you in advance!
Thank you both for your response, but unfortunately, wantsFullScreenLayout set to YES or NO in the code didn't have any effect. I was able to push the Navigation Controller up by 20 using this line of code:
self.navigationController.navigationBar.frame = CGRectOffset(self.navigationController.navigationBar.frame, 0.0, -20.0);
but then what happened was that the View Controller did not move up with the Navigation bar and left a gap below the Navigation Bar and the View Controller. What eventually worked was checking the Wants Full Screen checkbox in IB in the MainWindow view controller that is automatically generated when you set up a view based application.
The gap you are seeing is the same height as a status bar. Check the status bar settings in your NIB file.
Chances are you want to make the UINavigationController the root view controller for the window, rather than whichever view controller you have now. That would be the better way to do it.
The reason you're seeing that extra margin at the top is because UINavigationController normally expects that it will be sized to fill the entire screen (except perhaps a tab bar at the bottom, if it's inside a UITabBarController), and therefore expects that the top edge of its view will be under the status bar if the status bar is visible. Therefore, it places its navigation bar 20 pixels below the top of its view to leave space for the status bar, without bothering to check whether its view actually is under the status bar. Interestingly, sometimes a re-layout operation will perform this check, but that's unreliable. What I've found works well in a situation like this is to set the UINavigationController's wantsFullScreenLayout property to NO. Then ti doesn't try to leave room for the status bar, so everything works as expected.
I've been struggling with this same issue this morning. Since setting the wantsFullScreenLayout property doesn't seem to have any effect, I resorted to using a little subclass, which worked fine:
#interface MyNavigationController : UINavigationController
#end
#implementation MyNavigationController
- (BOOL)wantsFullScreenLayout;
{
return NO;
}
#end
Its so simple to remove that gap..
self.navigationBar.view.frame = CGRectMake(0, -20, 320, 480);
I'm working in an iPad app that has a split view with a navigation controller in the detail view. The deepest view that can be in the navigation stack is an edit view where the user can edit data. I put an edit button as the rightBarButtonItem and when editing starts, change it to a done button.
When editing commences and the user touches on a particular field, I present a popoverview with a list of possible choices filtered by what they are typing - a form of autofill based on all the values of that field in all other objects.
This works fine, except if you try touching on the done button. The popover eats this touch and dismisses itself. So the user has to touch done again.
I tried using the uipopovercontroller's passthroughViews property, but UIBarButtonItem is not a view and there is no documented way to get the view for the done button or even the navigation bar. I can access the variable in gdb, but it isn't accessible via KVC.
Any ideas on how I can prevent the need to tap done twice?
I've thought about a gesture recognizer on the window, but that seems messy and I'd have to handle rotation.
In case anyone gets here from google, copypaste from other question:
The only solution I found for now is to create UIBarButtonItem with custom UIButton using
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
//code for styling button
UIBarButtonItem *b = [[[UIBarButtonItem alloc]
initWithCustomView:button]
autorelease]
and then
popoverController.passthroughViews = [NSArray arrayWithObject:b.customView];
But be prepared - you cannot create UIButton that looks like UIBarButtoItem. I ended up with creating image that reassembled UIBarButtonItem.
I need to display a UIView/UIViewController when the user taps a button and the modal view should appear just like how the key board appears from the bottom bar when you edit text in a UITextField. Using the following code, I get to show it as a pop up.
[self presentModalViewController:child animated:YES];
How to make it appear like the keyboard?
I understad modal views cover the entire screen. But I really want a view that covers only half the screen. So, please tell me why this doesn't work
MyController *controller = [[MyController alloc] initWithNibName:#"MyView" bundle:nil];
CGRect frame = CGRectMake(0,44,768,264);
[controller view].frame = frame;
contoller.delegate = self;
[[self view] addSubView:[controller view]];
[controller release];
I am trying to add a sub view to my current view and make it appear where the keyboard appears.
Check if your child.modalTransitionStyle == UIModalTransitionStyleCoverVertical.
(And a model view controller always cover the whole screen. If you just need to cover half of the screen like the keyboard, you need to put the view controller's view as a subview of the main view, then animate it in manually with animation blocks.)
I know its an old question, but an answer to this is to use a UIActionSheet.
It won't present a View Controller, but you can present custom views that only cover a portion of the screen.

Add UIPickerView & a Button in Action sheet - How?
I have presented a navigation controller (Nav1) as modal view controller from rootViewController
Then from Nav1 i created another navigation controller (Nav2) and presented it as modal view controller.
In nav2 when i click a table cell it pushes a view controller containing UITextField
Now the problem is when I click on UITextField it does not show iphone keyboard
Actually I am trying to make something like alarm label as in iphone clock app.
Just be sure for you have set the delegate the textfield...
[textField setDelegate:self];
why did you choose two nav controllers?
you can use tabbarcontroller by the way there is much more simpler way to achieve this.Search on google
check if
"reloadData"
is not executing before the UITextField becomes active
