百度推送的那些坑
首先先代码
第一步

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions //在这个方法中写
 // iOS10 下需要使用新的 API
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10.0) {
#ifdef NSFoundationVersionNumber_iOS_9_x_Max
        UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
        
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound + UNAuthorizationOptionBadge)
                              completionHandler:^(BOOL granted, NSError * _Nullable error) {
                                  // Enable or disable features based on authorization.
                                  if (granted) {
                                      [application registerForRemoteNotifications];
                                  }
                              }];
#endif
    }
    else
    {
        UIUserNotificationType myTypes = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
        
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:myTypes categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    }

第二步
// 注册推送成功后调用该方法
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    
    [BPush registerDeviceToken:deviceToken];
    [BPush bindChannelWithCompleteHandler:^(id result, NSError *error)
    {
        NSString *deviceTokenString = [[[[deviceToken description] stringByReplacingOccurrencesOfString:@"<"withString:@""] stringByReplacingOccurrencesOfString:@">" withString:@""]
                                       stringByReplacingOccurrencesOfString:@" " withString:@""];
        NSString *myChannel_id = [BPush getChannelId];
        [[NSUserDefaults standardUserDefaults] setObject:myChannel_id forKey:@"myChannel"];
        [[NSUserDefaults standardUserDefaults] setObject:deviceTokenString forKey:@"deviceToken"];
        [[NSUserDefaults standardUserDefaults] synchronize];
        [DeviceInfoService requestConfig];
    }];
}
// 注册推送失败
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
    
}

ios10之前用
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    [BPush handleNotification:userInfo];
    if (application.applicationState == UIApplicationStateActive || application.applicationState == UIApplicationStateBackground)
    {
        [[MessageService sharedMessageService] requestRecentMsgList];
    }
    else
    {
        [self pushDic:userInfo[@"jm"]];
    }
}
ios10之后
// 此方法是 用户点击了通知，应用在前台 或者开启后台并且应用在后台 时调起
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
    completionHandler(UIBackgroundFetchResultNewData);
    // 应用在前台，不跳转页面，让用户选择。
    if (application.applicationState == UIApplicationStateActive)
    {
        [[MessageService sharedMessageService] requestRecentMsgList];
    }
    // 应用在后台。当后台设置aps字段里的 content-available 值为 1 并开启远程通知激活应用的选项
    if (application.applicationState == UIApplicationStateBackground)
    {
        // 此处可以选择激活应用提前下载邮件图片等内容。
        isBackGroundActivateApplication = YES;
        [[MessageService sharedMessageService] requestRecentMsgList];
    }
    
    //杀死状态下，直接跳转到跳转页面。
    if (application.applicationState == UIApplicationStateInactive && !isBackGroundActivateApplication)
    {
        [self pushDic:userInfo[@"jm"]];
    }
    
}

当然除了这些程序里面还有一些需要配置的也是必须的
