【知识总结】（2）远程推送

推送SDK：极光推送

---

后台点击推送： iOS 10 以下收到推送点击触发

方法已废弃 - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification 

- (void)application:(UIApplication *)application
    didReceiveRemoteNotification:(NSDictionary *)userInfo
          fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

iOS 10 以上触发：

极光推送中使用到的方法

- (void)jpushNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {

1，app接收推送

app状态：

a，app�前台状态（前台锁屏即后台状态）

收到推送消息，不会有消息提示的弹出，下面的方法接收到响应，进行相关的处理；在iOS 10 以后也会出现消息提醒的弹出，不会调用这个方法

//收到消息就可以触发，不需要点击操作
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

状态
application.applicationState == UIApplicationStateActive

b，app后台（包括锁屏）

//点击推送消息时触发
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

状态 // 不活跃
application.applicationState == UIApplicationStateInactive

c，app关闭 （包括关闭后锁屏）

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

状态 // 不活跃
application.applicationState == UIApplicationStateInactive

---

极光推送中通过下面方法判断app是正常打开还是通过点击推送打开

// 软件打开时调用方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions; 

// 查看字典是否存在，存在：推送点击进入   不存在：正常打开
// apn 内容获取：
NSDictionary *remoteNotification = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey]；

查看userInfo信息：

NSDictionary *userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    [Utils alertTitle:@"application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler" message:[NSString stringWithFormat:@"%@ --- %ld", [userInfo mj_JSONString], application.applicationState] delegate:nil cancelBtn:@"确定" otherBtnName:nil];

app正常打开情况，userInfo为空；
点击推送消息进入，userInfo中携带推送消息，如图：

app关闭状态进入didFinish打印信息

仔细观察，可以看到app关闭点击推送消息进入，在 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions; 和-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler中的userInfo是相同的

因此，app关闭点击推送消息进入时的处理操作可以在这里进行处理

二，极光推送

极光推送中提供了的接收推送消息和点击消息响应的方法

1，接收消息

前台接收到消息

1，didFinishLoad方法中注册通知

- (void)registerJPushCustomMessage{
    NSNotificationCenter *defaultCenter = [NSNotificationCenter defaultCenter];
    [defaultCenter addObserver:self selector:@selector(networkDidReceiveMessage:) name:kJPFNetworkDidReceiveMessageNotification object:nil];
}

收到推送时调用方法

- (void)networkDidReceiveMessage:(NSNotification *)notification {
    
    NSDictionary * userInfo = [notification userInfo];
    [Utils alertTitle:@"networkDidReceiveMessage" message:[NSString stringWithFormat:@"%@", [userInfo mj_JSONString]] delegate:nil cancelBtn:@"确定" otherBtnName:nil];
}

2，iOS10中，如果前台收到推送消息，会调用这个方法

// iOS 10 Support
- (void)jpushNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(NSInteger))completionHandler {
    // Required
    NSDictionary * userInfo = notification.request.content.userInfo;
    if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        [JPUSHService handleRemoteNotification:userInfo];
    }
    
    // 进行相应的处理
    // coding...
    
    completionHandler(UNNotificationPresentationOptionAlert); // 需要执行这个方法，选择是否提醒用户，有Badge、Sound、Alert三种类型可以选择设置
}

2，点击响应

iOS10：
后台和软件关闭状态点击收到的推送消息

// iOS 10 Support
- (void)jpushNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {
    
    // Required
    NSDictionary * userInfo = response.notification.request.content.userInfo;
    if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        [JPUSHService handleRemoteNotification:userInfo];
    }
    
    // 进行响应的处理
    //coding ...

    completionHandler();  // 系统要求执行这个方法
}

iOS10中，使用上面的两个方法处理，系统的方法是不起作用的
