AppDelegateExtension

使用通知和runtime-AOP的为AppDelegate瘦身方案

使用姿势

objective-C的工程

main.m：

int main(int argc, char * argv[]) {
    @autoreleasepool {
        installAppDelegateExtensionsWithClass([AppDelegate class]);
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

swift的工程

1.删除AppDelegate.swift中的@UIApplicationMain

2.添加main.swift到工程里并添加：

installAppDelegateExtensionsWithClass(AppDelegate.self)

UIApplicationMain(
    CommandLine.argc,
    UnsafeMutableRawPointer(CommandLine.unsafeArgv).bindMemory(to: UnsafeMutablePointer<Int8>.self, capacity: Int(CommandLine.argc)),
    nil,
    NSStringFromClass(AppDelegate.self)
)

添加了以下这些Notification key

UIKIT_EXTERN NSNotificationName const UIApplicationDidRegisterUserNotificationSettingsNotification;
UIKIT_EXTERN NSNotificationName const UIApplicationDidRegisterForRemoteNotificationsNotification;
UIKIT_EXTERN NSNotificationName const UIApplicationDidFailToRegisterForRemoteNotificationsNotification;
UIKIT_EXTERN NSNotificationName const UIApplicationDidReceiveRemoteNotification  NS_DEPRECATED_IOS(3_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate willPresentNotification:withCompletionHandler:] or -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:] for user visible notifications and -[UIApplicationDelegate application:didReceiveRemoteNotification:fetchCompletionHandler:] for silent remote notifications");
UIKIT_EXTERN NSNotificationName const UIApplicationDidReceiveLocalNotification NS_DEPRECATED_IOS(4_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate willPresentNotification:withCompletionHandler:] or -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:]");
UIKIT_EXTERN NSNotificationName const UIApplicationHandleOpenURLNotification NS_DEPRECATED_IOS(2_0, 9_0, "Please use application:openURL:options:");
UIKIT_EXTERN NSNotificationName const UIApplicationOpenURLWithSourceApplicationNotification NS_DEPRECATED_IOS(2_0, 9_0, "Please use application:openURL:options:");
UIKIT_EXTERN NSNotificationName const UIApplicationOpenURLWithOptionsNotification;
UIKIT_EXTERN NSNotificationName const UIApplicationContinueUserActivityNotification;
UIKIT_EXTERN NSNotificationName const UIApplicationPerformActionForShortcutItemNotification;
UIKIT_EXTERN NSNotificationName const UIApplicationHandleWatchKitExtensionRequestNotification;

Features:

• AOP没有使用category来实现methodswizzle，因为不是所有工程的AppDelegate起名相同，因此需要在load中显式调用一行注册代码。
• 增加了常用的UIApplicationDelegate方法对应的通知，可以根据自已业务的情况补充。

代码中参考了BlocksKit和libextobjc的实现，感谢两位大神的精彩code

Podfile

可以使用cocoapods集成
