iOS推送相关

1、清除推送的badgeNumber

在bugtags后台bug时发现，有用户因为下面的代码，而崩溃。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [[YKPushManager shareYKPushManager] yk_initJpushServiceWithOptions:launchOptions];   //推送
   [UIApplication sharedApplication].applicationIconBadgeNumber = 0;
    return YES;
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
   [UIApplication sharedApplication].applicationIconBadgeNumber = 0;
}

查找原因得知

 // set to 0 to hide. default is 0. In iOS 8.0 and later, your application must register for user notifications using -[UIApplication registerUserNotificationSettings:] before being able to set the icon badge.

意思是要先注册推送，才能设置角标，可是我注册了推送啊，what？这是什么原因？！

后来发现是设置角标的写法有问题，正确的写法是：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [[YKPushManager shareYKPushManager] yk_initJpushServiceWithOptions:launchOptions];   //推送
    [self resetBageNumber];
    return YES;
}
- (void)applicationWillEnterForeground:(UIApplication *)application {
  [self resetBageNumber];
}
- (void)resetBageNumber
{
    if ([UIApplication sharedApplication].applicationIconBadgeNumber > 0) {
        if (@available(iOS 11.0, *)) {
            [UIApplication sharedApplication].applicationIconBadgeNumber = -1;
        } else {
            UILocalNotification *localNotification = [[UILocalNotification alloc] init];
            localNotification.fireDate = [NSDate date];
            localNotification.applicationIconBadgeNumber = -1;
            [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
        }
    }
}

后来有发现了一个问题，如上设置之后，还有点小问题。就是点一下， 其他推送的消息也不见了，这样角标数量 不太正确 ，进来就给清了，但是呢，但是推送信息还在。

故又做了如下的修改：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
   [[YKPushManager shareYKPushManager] yk_initJpushServiceWithOptions:launchOptions];   //推送

    [self setPushBageNumberWith:launchOptions];
    return YES;
}
- (void)setPushBageNumberWith:(NSDictionary *)launchOptions
{
    NSDictionary *remoteNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
//如果remoteNotification = nil，则表示推送没有内容，不是从推送消息点击来的
    if (remoteNotification) {
        [[YKPushManager shareYKPushManager] dealBadgeNumber:launchOptions];
    }else{
        [self resetBageNumber];
    }
}
- (void)applicationWillEnterForeground:(UIApplication *)application {
  [self resetBageNumber];
}

下面是YKAppDelegate中推送相关的回调函数

pragma mark - 推送回调函数
// 向苹果注册推送，在调用 registerForRemoteNotificationTypes “成功”后会触发这个回调函数
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    [[YKPushManager shareYKPushManager] yk_registerDeviceToken:deviceToken];
}

//此处是点击推送消息进来调用两次
- (void)handleRemoteNotification:(NSDictionary * _Nonnull)userInfo {
    NSString *msgID = [userInfo[@"_j_msgid"] stringValue];
    DLog(@"msgID == %@",msgID);
    if (![msgID isEqualToString:[YKPushManager shareYKPushManager].messageID]) {
        [[YKPushManager shareYKPushManager] yk_handleRemoteNotification:userInfo];
        [YKPushManager shareYKPushManager].messageID = msgID;
    }
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler{
    DLog(@"收到通知: user info:%@",userInfo);
    [self handleRemoteNotification:userInfo];
    
    completionHandler(UIBackgroundFetchResultNewData);
}

#pragma mark -iOS 10 以前的推送系统处理方法
// 消息推送: 消息推送时应用正在运行，会进入到这里，
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    DLog(@"didReceiveRemoteNotification is %@",userInfo);
    [self handleRemoteNotification:userInfo];
}

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    DLog(@"didReceiveLocalNotification received message is %@",notification);
    [[YKPushManager shareYKPushManager] yk_showLocalNotification:notification];
}

    //Required
    // 如需继续使用pushConfig.plist文件声明appKey等配置内容，请依旧使用[JPUSHService setupWithOption:launchOptions]方式初始化。

    BOOL isProduction = YES;
