I wanted to Push New View Controller with Transparent Background on top of one View Controller which is already shown. I know How to PRESENT but I wanted to PUSH new View Controller.
UIViewController *controller = [[UIViewController alloc] init];
self.definesPresentationContext = YES;
controller.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[self presentViewController:controller animated:YES completion:^{}];
You need to give memory to your ViewController and set to RootController of UINavigationController. After that, you can push it from your current controller...
UIViewController *yourViewController = [[UIViewController alloc] init];
UINavigationController *navigationController1 = [[UINavigationController alloc] initWithRootViewController:yourViewController];
[self presentViewController:navigationController1 animated:YES completion:nil];

I have 5 view controller and want to come back from the last view to 1st view controller
Call a function in which you have to change the app rootviewcontroller. set it as a navigationController
yourViewcontoller *viewController = [[yourViewContoller alloc] init];
UINavigationController *navController=[[UINavigationController alloc]initWithRootViewController:viewController];
self.window.rootViewController = navController;
If you're using storyboards, give the UINavigationController a Storyboard ID. You can then initiate it and present through the code:
UINavigationController *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"<Storyboard ID>"];
[self presentViewController:vc animated:YES completion:nil];
Use this method on Animation splash screen
[self performSelector:#selector(setHidden:) withObject:nil afterDelay:2.0];
-(void) setHidden:(id)sender
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboare" bundle:nil];
YourVC* vController = (YourVC*)[Storyboard instantiateViewControllerWithIdentifier:#"storyboardId"];
UINavigationController *navcotoller=[[UINavigationController alloc]initWithRootViewController:vController];
self.window.rootViewController =navcotoller;
}
If you are using UINavigationController you could and should simply call
[self.navigationController popToRootViewControllerAnimated:YES];
i'm trying to implement a modal presentation of my settingsViewController. This works fine, but when it is presented it is not showing the tableView which is in the SettingsViewController. It just show a grey background and navigation bar. How come it is not showing my tableView inside the SettingsViewController?
SettingsViewController *settingController = [[SettingsViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:settingController];
navigationController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:navigationController animated:YES completion:NULL];
I have a UIViewController, and inside that view controller I would like to call a CustomUIViewController without the use of Interface Builder. I've been using this and it works but it requires a storyboard ID.
UIStoryboard *storyboard = self.storyboard;
UIViewController *myVC = (UIViewController *)[storyboard instantiateViewControllerWithIdentifier:#"PageID"];
[self presentModalViewController:myVC animated:YES];
Is there a way of going from a UIViewController to a customViewController without the use of segues and IB?
Use this:
UIViewController *myVc = [[UIViewController alloc] init];
[self presentViewController:myVc animated:YES completion:nil];
This will obviously present a new blank view controller, if you want your PageID view then you replace UIViewController with the name of the PageID class (i,e the .h/.m file names)
So i'm assuming this:
PageID *myVc = [[PageID alloc] init];
[self presentViewController:myVc animated:YES completion:nil];
If you want it inside a navigation controller do:
PageID *myVc = [[PageID alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:myVc];
[self presentViewController: navController animated:YES completion:nil];
OR if you don't want it to be modal (don't need to create a new navigation controller as it will be added to the existing navigation controller stack i.e. [self navigationController]:
[[self navigationController] pushViewController:myVc animated:YES];
Currently, when a button is tapped, a UIModalPresentationSheet comes up. I'd like to add a navigation bar at the top of this when it slides up. I've tried a lot of things but nothing seems to work. Here's what i'm currently trying and it returns this error.
AthleteAdd *addAthlete = [self.storyboard instantiateViewControllerWithIdentifier:#"addAthlete"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addAthlete];
//[self.navigationController pushViewController:addAthlete animated:YES];
addAthlete.delegate = self;
addAthlete.modalPresentationStyle = UIModalPresentationFormSheet;
// UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:addAthlete];
[self presentViewController:navigationController animated:YES completion:nil];
But it pushes it up modally, and without the modalpresentationsheet form. How can I make it so the navigation controller is sized correctly?
Try to change your code like this :
AthleteAdd *addAthlete = [self.storyboard instantiateViewControllerWithIdentifier:#"addAthlete"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addAthlete];
addAthlete.delegate = self;
navigationController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:navigationController animated:YES completion:nil];
Because here, you try to present addAthlete from itself. So you get this error.
You should present navigationController in which you encased your addAthlete.
[self presentViewController:navigationController animated:YES completion:nil];
You are presenting from current viewcontroller itself.
Try something like,
[self dismissViewControllerAnimated:YES completion:^{
[self.parentViewController presentViewController: navigationController animated:YES completion:nil];
}];
I am developing a ViewController (login app) with a single button, when I press this button I want to appear my UISplitView like this:
- (IBAction)loadSplitViewController:(id)sender {
[self showSplitViewController];
}
and the code developed for the creation of my splitViewController is this:
-(void)showSplitViewController{
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"MainStoryboard_iPad" bundle: nil];
LeftViewController *leftViewController = [mainStoryboard instantiateViewControllerWithIdentifier:#"LeftViewController"];
RightViewController *rightViewController = [mainStoryboard instantiateViewControllerWithIdentifier:#"RightViewController"];
UINavigationController *leftNavController = [[UINavigationController alloc] initWithRootViewController:leftViewController];
UINavigationController *rightNavController = [[UINavigationController alloc] initWithRootViewController:rightViewController];
UISplitViewController *splitViewController = [[UISplitViewController alloc] init];
splitViewController.viewControllers = [NSArray arrayWithObjects:leftNavController, rightNavController, nil];
leftViewController.delegate = rightViewController;
splitViewController.delegate = rightViewController;
[self presentViewController:splitViewController animated:YES completion:^{}];
}
the thing is... if I use for display my splitViewController this line:
[self presentViewController:splitViewController animated:YES completion:^{}];
throws me an error
I also tried with
[self.view addSubview:splitViewController.view];
but this way my splitViewController never rotates, and delegates doesn't work as well... and I don't want my splitViewController to be a subview of my viewController, I want it to appear more like an independient modalView
any help I'll appreciate
thanks in advance
Split view controllers really should be the root view controller of the window (in fact Apple says it has to be, though there seem to be some examples where this isn't true). Instead of presenting it, you could just switch the window's root view controller to be the split view controller.
self.view.window.rootViewController = splitViewController;
