I have a plus button in my primary view controller of a UISplitViewController and i want to present something modally in my detail view, just like apple does when adding a new contact in address book in iPad. I have tried everything but nothing. I managed to do it but when i am trying to embed my presented view controller into a UINavigation controller then my presented controller covers the full screen. Any suggestions? Here is my code:
UINavigationController *navController = [self.splitViewController.viewControllers lastObject];
DetailTableViewController *controller = (DetailTableViewController *)navController.topViewController;
controller.definesPresentationContext = YES;
controller.providesPresentationContextTransitionStyle = YES;
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
EditTableViewController *etvc = (EditTableViewController *)[storyboard instantiateViewControllerWithIdentifier:#"EditTableViewController"];
UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:etvc];
etvc.patient = patient;
if (IDIOM == IPAD)
{
etvc.modalPresentationStyle = UIModalPresentationCurrentContext;
[controller presentViewController:nav animated:YES completion:nil];
} else {
[self presentViewController:nav animated:YES completion:nil];
}
I just successfully solved this problem by creating a custom segue whose implementation is:
- (void)perform
{
UIViewController *ctrl = self.sourceViewController;
UIViewController *dest = self.destinationViewController;
dest.modalPresentationStyle = UIModalPresentationCurrentContext;
[ctrl presentViewController:dest animated:YES completion:nil];
}
I'm seeing the behavior I want by invoking this segue from my detail view controller on the modal view I want to overlay it.
I think where your code is going haywire is here:
etvc.modalPresentationStyle = UIModalPresentationCurrentContext;
I think it should be:
nav.modalPresentationStyle = UIModalPresentationCurrentContext;
Though I haven't tested it.
Note that the Apple docs suggest that modalPresentationStyle is ignored on the iPhone (or on "horizontally compact devices"), so your "IS_IPAD" check may be redundant.
Hope this helps!

So I had a full working solution in iOS7 that displays a LoginViewController via presentViewController in the AppDelegate's didFinishLaunching.
Basically I am doing something like this:
UIViewController *backgroundViewController = ...
self.window.rootViewController = backgroundViewController;
[self.window makeKeyAndVisible];
[self.window.rootViewController presentViewController:loginViewController
animated:NO ...]
In iOS8 I see a jump. First I see the backgroundViewController then after about 1 second or so the login appears.
So, how can I prevent this jump in iOS8?
I am seeing that are a ton of developers with this kind of problem but still didn't find a solution.
Also a hack (for now), but just one line of code
Add the view of the view controller you're presenting to the window before presentation
UIViewController *viewController = [[UIViewController alloc] init];
[viewController.view setBackgroundColor:[UIColor greenColor]];
// Temporary iOS8 fix for 'presentation lag' on launch
[self.window addSubview:viewController.view];
[self.window.rootViewController presentViewController:viewController animated:NO completion:nil];
If you are presenting a navigation controller than add the navigation controller's view instead of its top view controller.
I have a quick hacky fix:
//Make a screenshot of the ViewController first, or use a real image if you want
__block UIImageView *fakeImageView = [[UIImageView alloc] initWithImage:image];
fakeImageView.frame = vc.view.frame;
[self.view addSubview:fakeImageView];
[self presentViewController:vc animated:animated completion:^{
[fakeImageView removeFromSuperview];
fakeImageView = nil;
}];
It is not good for long term, but can quickly fix this issue without changing too much code.
Waiting for better solutions.
You can set the window to an instance of a temporary controller.
self.window.backgroundColor = [UIColor whiteColor]; //do some styling etc.
self.window.rootViewController = [LoginViewController new];
[self.window makeKeyAndVisible];
From the set controller (LoginViewController) you can push your real login controller with the desired transition. Once the login sequence is over you can make a transition from the login controller to the default application root view controller.
[UIView transitionWithView:[AppGlobal sharedApp].applicationWindow
duration:0.75
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
[AppGlobal sharedApp].applicationWindow.rootViewController = [AppRootViewController new];
} completion:nil];
I have also faced the same problem in iOS8 and I found this solution:
ABCViewController *obj = [[ABCViewController alloc] initWithNibName:#"ABCViewController" bundle:nil];
CATransition *transition = [CATransition animation];
transition.duration = 0.4;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromBottom;
transition.delegate = self;
[self.navigationControler.view.layer addAnimation:transition forKey:nil];
[appDelegate.navigationControler obj animated:NO];
obj = nil;
I hope this solution can help you!
This should work:
call [loginViewController view]
Before presenting it.
i want to add Airdrop sharing to my spritekit game
It dosent work using this code:
UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
[self presentViewController:controller animated:YES completion:nil]
I am thinking the issue is where you have the code you posted. You possibly have it in viewDidLoad of your UIViewController.
Do this in your UIViewController :
-(void)viewDidAppear:(BOOL)animated
{
// assuming you are creating objectsToShare here or before this point
UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
[self presentViewController:controller animated:YES completion:nil]
}
I believe the issue is that the view is not fully configured when you are trying to add your UIActivityViewController.
I believe that the bounds and some other properties of the view are not yet properly configured in the viewDidLoad method, which results in a failure to display it.
I have a UIViewController which contains a UICollectionView. On tapping any of the UICollectionViewCell I present a modal view controller.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
PopViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"DetailsView"];
vc.view.backgroundColor = [UIColor clearColor];
vc.transitioningDelegate = self;
vc.modalPresentationStyle = UIModalPresentationCustom;
[self presentViewController:vc animated:YES completion:nil];
The PopViewController shows up correctly. Now I want to restrict the device orientation when PopViewController is being presented. That is if PopViewController is presented in portrait mode then it should not change to landscape even if I switch to landscape mode (using Rotate Left or Right in simulator) until I dismiss the PopViewController.
I have used following code in PopViewController:
-(BOOL)shouldAutorotate {
return NO;
}
What else (or instead) is needed to lock the pop up view to the current orientation?
in your modal controller try to add this, also (iOS > 6)
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
to support iOS 5 or below you must additional add:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
Someone gave me this code, is it correct? if so how do i use it? I am a noob so can you explain in simpler terms for me? Thanks guys :)
- (IBAction)OpenActionSheetButton:(id)sender {
UIActionSheet *actionsheet = [[UIActionSheet alloc]initWithTitle:#"There is no going back,

[actionsheet showInView:self.view];}

I'm not sure with the case with storyboard, but with the case of XIB, I need to set UINavigationController object as rootviewcontroller, so that I can push from one viewcontroller to another, I think in storyboard it may be the same, if so, see these answers, first and second to set navigation controller as rootviewcontroller in storyboard environment.
I have a problem, I have created a project window based application in xcode, then I create a UITabBarController that manages two views all programmatically, the second view is a tableView and I want to see in the top a UINavigationController, I have tried a lot but I don't know how to have a UINavigationController in the second view. this is the code:
ProjectAppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//Creo una tabBarController
UITabBarController *tabBarController = [[UITabBarController alloc] init];
//Create the two view controllers
UIViewController *vc1 = [[Visuale1ViewController alloc] init];
UIViewController *vc2 = [[Visuale2ViewController alloc] init];
//Make an array containing the two view controllers
NSArray *viewControllers = [NSArray arrayWithObjects:vc1, vc2, nil];
//The viewControllers array retains vc1 and vc2, we can release
//our ownership of them in this method
[vc1 release];
[vc2 release];
//Attach them to the tab bar controller
[tabBarController setViewControllers:viewControllers];
//Setto la tabBarController come rootViewController di window
[window setRootViewController:tabBarController];
//The window retain tabBarController, possiamo lasciare il nostro riferimento
[tabBarController release];
[self.window makeKeyAndVisible];
return YES;
}
Visuale1ViewController.h
#implementation Visuale1ViewController
- (id)init{
[super initWithNibName:#"Visuale1ViewController" bundle:nil];
//Get the tab bar item
UITabBarItem *tbi = [self tabBarItem];
//Give it a label
[tbi setTitle:#"Visuale 1"];
return self;
}
// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
- (id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)bundle {
return [self init];
}
Visuale2ViewController.h
#implementation AnswerViewController
- (id)init{
//Call the superclass's designated initializer
/*[super initWithNibName:nil
bundle:nil];*/
[super initWithStyle:UITableViewStyleGrouped];
answers = [[NSMutableArray alloc] init];
for (int i = 0; i<10 ; i++) {
[answers addObject:[Answer DefaultAnswer]];
}
//Get the tab bar item
UITabBarItem *tbi = [self tabBarItem];
//Give it a laber
[tbi setTitle:#"Visuale 2"];
return self;
}
- (id)initWithStyle:(UITableViewStyle)style{
return [self init];
}
//All below are all methods to work the table view, and all go well, the only problem it's the UINavigationController, to manage then the detail of the table...
Now I want to know how I can put a UINavigationController in the second view. I try do this, in ProjectAppDelegate.m:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//Creo una tabBarController
UITabBarController *tabBarController = [[UITabBarController alloc] init];
//Create the two view controllers
UIViewController *vc1 = [[Visuale1ViewController alloc] init];
UIViewController *vc2 = [[Visuale2ViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:vc2];
//Make an array containing the two view controllers
NSArray *viewControllers = [NSArray arrayWithObjects:vc1, navController, nil];
//The viewControllers array retains vc1 and vc2, we can release
//our ownership of them in this method
[vc1 release];
[vc2 release];
//Attach them to the tab bar controller
[tabBarController setViewControllers:viewControllers];
//Setto la tabBarController come rootViewController di window
[window setRootViewController:tabBarController];
}
In this way I can visualize the NavigationBar, but I lost the name of the SecondTabBar. Sorry for my english, how I can do this?
Yes in the second view you have to set title as
[self.navigationItem setTitle:#"Visuale2"];
For TabBar title-
UITabBar *tabBar = [self.tabBarController tabBar];
NSArray *tabBarItems = [tabBar items];
UITabBarItem *secondTabBarItem = [tabBarItems objectAtIndex:1];
[secondTabBarItem setTitle:#"Visuale2"];
I left the code as it was and I added in init Visale2ViewController this:
UIImage *i = [UIImage imageNamed:#"Hypno.png"];
[tbi setImage:i];
and now in can see the text Visuale2 in tabBar and the image...i don't know why...
You need to set the tabBarItem property for your UINavigationController. Something like this.
UITabBarItem *tabItem = [[UITabBarItem alloc] initWithTitle:#"Visuale 2" image:nil tag:1];
UIViewController *vc2 = [[Visuale2ViewController alloc] init];
navController = [[UINavigationController alloc] initWithRootViewController:vc2];
navController.tabBarItem = tabItem;
After looking at it,the scenario seems to be same like me.What I faced for the first time when doing Tab+Navigation.
I am sure that there is some problem with your Tab+Navigation based application. Although it shows the Tab as well as navigation are not able to navigate the basic flow.And it is very difficult to solve your problem with such less code.
Instead of this, I had an alternate solution for the same:
Once you have a tab bar in a XIB, the easiest way to approach this is to drag a UINavigationController object over from the Library window (looks like a left nav bar button on a gold background) into the Tree View for your tab bar (the text only view, not the GUI). Place it under the tab bar, then drag your existing view controller under the tab bar controller instead of under the tab bar.
When you go to view that tab you should then see a navigation bar on the top of it... if you are loading the navigation controller from another xib, you'll modify the nav bar in the tab bar xib.
else you can below you can follow the best url for the same:
