iOS零行代码搞定本地通知

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];
/*

*/
}
-(void)GIN_application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
[self GIN_application:application didReceiveLocalNotification:notification];
/*

*/
}
