I have a custom URL scheme and i want to open a certain ViewController
which is not the root when i go to this URL. I have been able to do that and what remains is
To deal with pushing and popping the viewControllers from AppDelegate, you need to use [UIApplication sharedApplication]
which keeps track to all of viewControllers, beginning with root one.
To PUSH ViewController from AppDelegate
ListingViewController *listingVC = [[ListingViewController alloc] init];
[(UINavigationController *)self.window.rootViewController pushViewController:listingVC animated:YES];
To POP that ViewController you just presented, you need to use this code
[(UINavigationController *)[UIApplication sharedApplication].keyWindow.rootViewController popViewControllerAnimated:YES ];
For Swift 3 version:
let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewControlleripad : UINavigationController = mainStoryboardIpad.instantiateViewController(withIdentifier: "initial") as! UINavigationController
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = initialViewControlleripad
self.window?.makeKeyAndVisible()
If your using storyboard then you could use below lines for pushing your VC.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
YOURCLASS *obj=[storyboard instantiateViewControllerWithIdentifier:@"YOUR_CLASS_STORYBOARD_ID"];
[self.window.rootViewController.navigationController pushViewController:obj animated:YES];
Update:-
ListingViewController *listingVC = [[ListingViewController alloc] init];
UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:listingVC];
[self.window.rootViewController presentViewController:navCon animated:YES completion:nil];
Write this code in didFinishingWithLaunchingOptions
SecViewController *Vc = [[UIStoryboard storyboardWithName:@"Main" bundle:nil]instantiateViewControllerWithIdentifier:@"second"];
[(UINavigationController *)self.window.rootViewController pushViewController:Vc animated:YES];
If you want to push a UIViewController, you probably are forgetting to init it with the NibName:
LoginViewController *loginViewController = [[LoginViewController alloc]initWithNibName:@"LoginViewController" bundle:nil];
Your AppDelegate.m should look like this:
#import "TestViewController.h"
@interface AppDelegate ()
@property (strong, nonatomic) TestViewController *viewController;
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[TestViewController alloc]init];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
