iOS远程推送

1.创建推送相关证书.
  

2.在启动AppDelegate方法中调用注册远程通知
/*第2种app已经被关闭（进程已死）
 启动app，启动完毕会调用AppDelegate的下面方法*/
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
 
    //注册远程通知,iOS8.0以上的方法
    
    UIUserNotificationSettings *settingNoti = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert  categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settingNoti];
    [application registerForRemoteNotifications];

//iOS7.0及以下的方法
//    UIRemoteNotificationType type = UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound;
//    [application registerForRemoteNotificationTypes:type];
    
    //进程已经被关闭(进程已死,再进来),获取远程通知内容
    UILocalNotification *location = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
    if (location) {
        
        NSLog(@"%@",location.userInfo);
    }else{
        NSLog(@"%@",location.userInfo);
    }
    
    return YES;
}
//注册成功后会调用AppDelegate的下面方法，得到设备的deviceToken

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    
    NSLog(@"获取deviceToken:%@",deviceToken);
    
}
/*当设备接收到远程推送通知时
如果程序是处于关闭状态，系统会在给用户展示远程推送通知的同时，将程序启动到后台，并调用AppDelegate的下面方法*/
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
    if (userInfo) {
        NSDictionary *aps = userInfo[@"aps"];
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"新的消息" message: [NSString stringWithFormat:@"%@",aps[@"alert"]] delegate:self cancelButtonTitle:nil otherButtonTitles:@"取消", nil];
        [alert show];
       
    }   
}
/*当用户点击远程推送通知，会自动打开app，这里有2种情况
第1种:app并没有关闭，一直隐藏在后台
让app进入前台，并会调用AppDelegate的下面方法（并非重新启动app*/
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(UILocalNotification *)notification{
    
    NSLog(@"remoteNotification=%@",notification);
}
/*可以在这个方法中做些数据下载操作，争取在用户点击通知前，就将数据下载完毕

下载完毕要调用completionHandler这个block，告知下载完毕
completionHandler(UIBackgroundFetchResultNewData);*/
3.下载PushMeBadyDemo,测试远程通知

//注意使用PushMeBady时,在ioSock.h文件中把不必要的错误注释了如下面所示.
//#include <CoreServices/../Frameworks/CarbonCore.framework/Headers/MacTypes.h>
//电脑上导入开发者或发布者推送证书.修改名字为apns.cer

//这里填写的获取的DeviceToken
self.deviceToken = @"e3094258 d8766f77 f29dfbfa ec3e3e83 8f0c213e 01e0eeea cc040536 e7d41730"; 
        
   //这里是发布远程通知内容
        self.payload = @"{\"aps\":{\"alert\":\"星仔爱善良的女孩.\",\"badge\":1}}";
//这里是远程通知APNs发布证书
        self.certificate = [[NSBundle mainBundle] pathForResource:@"apns" ofType:@"cer"];

1.一套远程推送解决方案，支持android和iOS两个平台
2.它能够快捷地为iOS App增加推送功能，减少集成APNs需要的工作量、开发复杂度
