in my iOS App i need to change the rootviewController of the window in between of app .so when i change my rootviewcontroller dyncamically its flicking the view before its change.but what i want is to give a smooth transition when rootviewcontroller is changed.
i had tried with the following but its not the transition i want.
[UIView transitionWithView:self.window
duration:.8
options:UIViewAnimationOptionTransitionCurlUp
animations:^{
self.window.rootViewController = tabBarControllerMain;
[self.window makeKeyAndVisible];
}
completion:NULL];
i want specific transition like navigationcontroller pushview transition.
can any body give me idea how to achieve that?
Based on this Apple's documentation
UIViewController *viewControllerToBeShown=[[UIViewController alloc]init];
//viewControllerToBeShown.view.frame = self.view.frame;
viewControllerToBeShown.view.backgroundColor = [UIColor orangeColor];
AppDelegateClass *yourAppDelegate =(AppDelegateClass*)[UIApplication sharedApplication].delegate;
UIView *myView1 = yourAppDelegate.window.rootViewController.view;
UIView *myView2 = viewControllerToBeShown.view;
myView2.frame = yourAppDelegate.window.bounds;
[yourAppDelegate.window addSubview:myView2];
CATransition* transition = [CATransition animation];
transition.startProgress = 0;
transition.endProgress = 1.0;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
transition.duration = 5.0;
// Add the transition animation to both layers
[myView1.layer addAnimation:transition forKey:@"transition"];
[myView2.layer addAnimation:transition forKey:@"transition"];
myView1.hidden = YES;
myView2.hidden = NO;
yourAppDelegate.window.rootViewController = viewControllerToBeShown;
Swift
guard let appDelegate = UIApplication.shared.delegate,
let appDelegateWindow = appDelegate.window,
let appDelegateView = window.rootViewController?.view,
let viewContollersView = viewController.view else {
return
}
viewContollersView.frame = (appDelegateWindow?.bounds)!
appDelegate.window??.addSubview(viewContollersView)
let transition = CATransition()
transition.startProgress = 0
transition.endProgress = 1.0
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
transition.duration = 0.35
appDelegateView.layer.add(transition, forKey: "transition")
viewContollersView.layer.add(transition, forKey: "transition")
appDelegateView.isHidden = true
viewContollersView.isHidden = false
appDelegateWindow?.rootViewController = viewController
