本地通知很简单喽,关键是这个零行如何实现? 也许你已经知道了,runtime 嘛,只需要将 AppDelegate 的分类 .m文件拖进工程即可,彻底解放你的 AppDelegate.m;

一.原理解析:

使用runtime 在 +(void)load 替换 UIApplicationDelegate一些方法的实现,比如:

application:didFinishLaunchingWithOptions:
application:handleActionWithIdentifier:forLocalNotification:completionHandler:
...等等通知相关的代理方法,在自己的方法实现处理通知;

二.上代码:

1.新建 AppDelegate 分类,只要 .m文件即可:
2. 实现基本的方法交换接口:+(void)swapSelector:(SEL)systemSelector toSelector:(SEL)customSelector;
3. 在自己的方法实现中处理通知相关代码:
如下:
1 . 新建 AppDelegate 分类: 略过 ....
2 . 基本接口实现骨架:

+(void)swapSelector:(SEL)systemSelector toSelector:(SEL)customSelector{
//    static dispatch_once_t onceToken;
//    dispatch_once(&onceToken, ^{
        SEL org_Selector = systemSelector;
        SEL new_Selector  = customSelector;
        
        Method org_method = class_getInstanceMethod([self class], org_Selector);
        Method new_method  = class_getInstanceMethod([self class], new_Selector);
        
        BOOL isAdd = class_addMethod(self, org_Selector, method_getImplementation(new_method), method_getTypeEncoding(new_method));
        if (isAdd) {
            class_replaceMethod(self, customSelector, method_getImplementation(new_method), method_getTypeEncoding(new_method));
        }else{
            method_exchangeImplementations(org_method, new_method);
        }
//    });
}

注意: 这里的 dispatch_once 是注释掉的!!!!

3 . 在自己的方法实现中处理通知相关代码:

@implementation AppDelegate (LocalNotification)

+(void)load{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{  // 知道为什么上面没有 dispatch_once 了吧;
        [self swapSelector:@selector(application:didFinishLaunchingWithOptions:)                                                            toSelector:@selector(GIN_application:didFinishLaunchingWithOptions:)];
        [self swapSelector:@selector(application:didRegisterUserNotificationSettings:)  toSelector:@selector(GIN_application:didRegisterUserNotificationSettings:)];
        [self swapSelector:@selector(application:handleActionWithIdentifier:forLocalNotification:completionHandler:) toSelector:@selector(GIN_application:handleActionWithIdentifier:forLocalNotification:completionHandler:)];
        [self swapSelector:@selector(application:handleActionWithIdentifier:forLocalNotification: withResponseInfo: completionHandler:) toSelector:@selector(GIN_application:handleActionWithIdentifier:forLocalNotification: withResponseInfo: completionHandler:) ];
        [self swapSelector:@selector(application:didReceiveLocalNotification:) toSelector:@selector(GIN_application:didReceiveLocalNotification:)];
    });
    
}


-(BOOL)GIN_application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    [self GIN_application:application didFinishLaunchingWithOptions:launchOptions];
    [self configLocalNotificationWithApplication:application];
    return YES;
}

-(void)GIN_application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings{
    [self GIN_application:application didRegisterUserNotificationSettings:notificationSettings];
    /*
     *  your code (通知相关)
     */
    
}

-(void)GIN_application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler{
    [self GIN_application:application handleActionWithIdentifier:identifier forLocalNotification:notification completionHandler:completionHandler];
    /*
     *  your code (通知相关)
     */
}

-(void)GIN_application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification withResponseInfo:(NSDictionary *)responseInfo completionHandler:(void (^)())completionHandler{
    [self GIN_application:application handleActionWithIdentifier:identifier forLocalNotification:notification withResponseInfo:responseInfo completionHandler:completionHandler];
    /*
     *  your code (通知相关)
     */
}

-(void)GIN_application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
    [self GIN_application:application didReceiveLocalNotification:notification];
    /*
     *  your code (通知相关)
     */
}

三.完整代码:

//
//  AppDelegate+LocalNotification.m

#import "AppDelegate.h"
#import <UserNotifications/UserNotifications.h>
#import "NSObject+swapMethod.h"

@interface AppDelegate ()<UNUserNotificationCenterDelegate>
@end
