Overview

RamblerAppDelegateProxy is your best cure against massive AppDelegate class. It provides a nice and clean way to divide all of the AppDelegate responsibilities between multiple helper classes.

Picture

Just imagine, that instead of 2k lines of code monster you have multiple simple classes:

  • StartAppDelegate – configures application on start up,
  • AnalyticsAppDelegate – configures analytics services,
  • RemoteNotificationAppDelegate – handles push-notifications,
  • SpotlightAppDelegate – handles start from spotlight results,
  • HandoffAppDelegate – handles start from handoff,
  • DeepLinkAppDelegate – incapsulates deep linking logic,
  • and anything else.

Key features

  • Provides all the infrastructure – you should only create your own mini-AppDelegate classes with single responsibilities.
  • Has simple dependency injection system for injecting your mini-instances,
  • Battle-tested into a lot of Rambler&Co projects.

Installation

pod RamblerAppDelegateProxy

Usage

Create a RemoteNotificationAppDelegate class which conforms to UIApplicationDelegate protocol.

@interface RemoteNotificationAppDelegate : NSObject <UIApplicationDelegate>

@end
...
@implementation RemoteNotificationAppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    NSDictionary *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (notification) {
        NSLog(@"Launching from push %@", notification);
    }
    return YES;
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    NSLog(@"Did register for remote notifications");
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
   NSLog(@"Did receive remote notification");}
}

@end

Change the main.m file implementation:

int main(int argc, char * argv[]) {
    @autoreleasepool {
        [[RamblerAppDelegateProxy injector] addAppDelegates:@[[RemoteNotificationAppDelegate new]]];

        return UIApplicationMain(argc, argv, nil, NSStringFromClass([RamblerAppDelegateProxy class]));
    }
}

Use your RemoteNotificationAppDelegate in the same way as the standart AppDelegate class – just remember to not mess its responsibilities.

Troubleshooting

Based on the concept, the proxy forwards only the methods defined in the protocol UIApplicationDelegate. If you need a additional method that must be implemented in AppDelegate, you need to create a subclass and implement this method in this class.

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@end

This subclass should be set as a default.

[[RamblerAppDelegateProxy injector] setDefaultAppDelegate:[AppDelegate new]];

This is necessary for example if you are using Typhoon. For injection depending in AppDelegates need to write a definition for RamblerAppDelegateProxy.

@implementation ApplicationAssembly

- (RamblerAppDelegateProxy *)applicationDelegateProxy {
    return [TyphoonDefinition withClass:[RamblerAppDelegateProxy class]
                          configuration:^(TyphoonDefinition *definition) {
                                [definition injectMethod:@selector(addAppDelegates:)
                                              parameters:^(TyphoonMethod *method) {
                                                    NSArray *appDelegates = @[
                                                        [self remoteNotificationAppDelegate]
                                                    ];
                                                    [method injectParameterWith:appDelegates];
                                                }];
                          }];
}

- (id<UIApplicationDelegate>)remoteNotificationAppDelegate {
    return [TyphoonDefinition withClass:[RCMLaunchingAppDelegate class]
                          configuration:^(TyphoonDefinition *definition) {
                          }];
}

@end
