Easily Switch UIWindow’s RootviewController

Developers

Summary

Easily switch UIWindow’s rootviewController with animations.

Description

In some scenarios you have to change the UIWindow’s rootviewController such as when the user’s token is invalidated on the server and you have to show another viewController, e.g. a login viewController. Although you can deal with pushing or presenting the viewController but using HyperWindowSwitch brings such benefits:

  • Allows to other viewControllers to be released (which preserves memory)
  • Provides several predefined animations
  • Supports custom animation.

Usage

1- Go to Xcode project settings, clear Main.storyboard for Main Interface field.
2- Import HyperWindowSwitch header into your AppDelegate’s m file:

#import "HyperWindowSwitch.h"

3- Let’s initialize HyperWindowSwitch. We will also create an instance of the viewController which we want to display at first. Add these lines to your application:didFinishLaunchingWithOptions method:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [HyperWindowSwitch initializeWindowForAppDelegate:self];

    //Instantiate the first viewController you want to display (you probably have to change this)
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UIViewController *home = [storyboard instantiateViewControllerWithIdentifier:@"HomeViewController"];

    //Tell HyperWindowSwitch to display it
    [HyperWindowSwitch setRootViewController:home];
    return YES;
}

Now for switching UIWindow’s viewController you can call this method from anywhere. (you may have to import HyperWindowSwitch.h)

[HyperWindowSwitch switchToviewController:logoutVC animationMode:HyperWindowSwitchAnimationModeFromBottom completion:^{}];

Supported Animations

When calling switchToviewController:animationMode:completion you can provide these values for the animationMode:

  • HyperWindowSwitchAnimationModeNone
  • HyperWindowSwitchAnimationModeFromBottom
  • HyperWindowSwitchAnimationModeFade

Custom Animations

As you know UITransitioning is used in combination with presentViewController method and it’s not meant to be used when switching the rootViewController. We have worked a lot to bring UITransitioning functionality into HyperWindowSwitch. We have also implemented a nice animation:
HyperWindowSwitchAnimationModeFromBottomWithCollision

To implement your custom animations, use UITransitioningDelegate as before. Then just pass HyperWindowSwitchAnimationModeTransitioningDelegate animationMode for HyperWindowSwitch.
Example:

    //Go to LoginViewController with custom animation.
    UIStoryboard* mainStroyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UIViewController* loginVC = [mainStroyboard instantiateViewControllerWithIdentifier:@"LoginNavigationController"];

    transitioningDelegate = [[MyTransitioningDelegate alloc] initWithTransitionMode: animationModeFade];
    loginVC.transitioningDelegate = transitioningDelegate;
    loginVC.modalPresentationStyle = UIModalPresentationCustom;

    [HyperWindowSwitch switchToViewController:loginVC animationMode:HyperWindowSwitchAnimationModeTransitioningDelegate completion:^{
    }];

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Installation

HyperWindowSwitch is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod "HyperWindowSwitch"
