modalviewcontroller

I have a mainViewController. I call [self pushModalViewController:someViewController] which makes someViewController the active view. Now I want to call a function in mainViewController as someViewController disappears with [self dismissModalViewController]. viewDidAppear does not get called probably because the view was already there, just beneath the modal view. How does one go about calling a function in the mainViewController once the modalView dismisses itself? Thanks a lot!

I would like to implement UIVisualEffectView to apply a blur effect to a view to show the view that lies behind it. This view that should have its background blurred is a UITableViewController that is embedded in a UINavigationController , and it will either be presented in a popover on iPad or it will be presented full screen modally on iPhone, thanks to iOS 8 adaptive segues (Present as Popover). When this view controller is in a popover I want the background to blur what's underneath the popover, and when it's presented full screen I want the background to blur the previous view controller.

I have a view controller hierarchy and the top-most controller is displayed as a modal and would like to know how to display the navigation bar when using 'UIViewController:presentViewController:viewControllerToPresent:animated:completion' The docs for 'presentViewController:animated:completion:' note: 'On iPhone and iPod touch, the presented view is always full screen. On iPad, the presentation depends on the value in the modalPresentationStyle property.' For 'modalPresentationStyle', the docs say: The presentation style determines how a modally presented view controller is displayed onscreen

I have a navigation based app that has a detail view (UIWebView) with action buttons across the bottom in a UIToolbar. I want to add 'notes' when the 'notes' button is pushed. Everything works fine when the webview is in portrait mode. I press the notes button, the modal view opens fine and works great. The problem occurs when the webview is in landscape mode. If I press the notes button, all the code to open the modal view gets called but all I get is a white screen. One comment: If I open the modal view in portrait and then rotate the device, it rotates fine into landscape mode. It just won

Just curious about the modal view controller usage. When and why should we use them? Is there a guideline? I found the sample core data book code create a navigation controller just to present a modal view controller. Why is that? UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:addViewController]; [self.navigationController presentModalViewController:navController animated:YES]; Is there a functional reason to this? Would it work if we just push the addViewController to self.navigationController? visakh7 Generally you use modal view

I am trying to display a UISplitViewController presenting it as a Modal View Controller in my iPad app. I manage to have it display, but for some reason there is a gap to the left of the modal view the size of a Status Bar which is also preserved when the orientation is changed. Does anybody know why this is happening? Or if this is even possible? Maybe I'm just digging myself a huge hole. The stock UISplitViewController was designed for use as the root view controller only. Presenting one modally goes against the Apple Human Interface Guidelines and has a high probability of getting rejected

I currently have a UIWebView that is displayed within a modal view. It is basically a detail view that provides a view of a page when the user clicks a link. When the view is dismissed and then brought up again (when the user clicks another link), the previously-loaded content is still visible and the new content loads "on top" of the last content. This makes sense because the instance of the UIWebView persists between sessions and is only released when the memory is needed. However, I would like to completely clear the UIWebView when the modal view is dismissed so that 1) content is cleared

I'd like to present modally, at first startup, a tutorial wizard to the user. Is there a way to present a modal UIViewController on application startup, without seeing, at least for a millisecond, the rootViewController behind it? Now I'm doing something like this (omitting first-launch checks for clarity): - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // ... UIStoryboard *storyboard = self.window.rootViewController.storyboard; TutorialViewController* tutorialViewController = [storyboard instantiateViewControllerWithIdentifier:@

Instead of setting uiviewcontroller's modalTransitionStyle , I want to add an CAAnimation(or some other thing). This code can perform an custom animation in navigationController CATransition* transition = [CATransition animation]; transition.duration = 0.4; transition.type = kCATransitionFade; transition.subtype = kCATransitionFromBottom; [self.navigationController.view.layer addAnimation:transition forKey:kCATransition]; [self.navigationController pushViewController:adjustViewController animated:NO]; How can I implement it to a Modal View Controller? You just need to add the transition to the
