iOS 本地接收消息推送

第一步：创建本地推送 

// 创建一个本地推送 

UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease]; 

//设置10秒之后 

NSDate *pushDate = [NSDate dateWithTimeIntervalSinceNow:10]; 

if (notification != nil) { 

    // 设置推送时间 

    notification.fireDate = pushDate; 

    // 设置时区 

    notification.timeZone = [NSTimeZone defaultTimeZone]; 

    // 设置重复间隔 

    notification.repeatInterval = kCFCalendarUnitDay; 

    // 推送声音 

    notification.soundName = UILocalNotificationDefaultSoundName; 

    // 推送内容 

    notification.alertBody = @"推送内容"; 

    //显示在icon上的红色圈中的数子 

    notification.applicationIconBadgeNumber = 1; 

    //设置userinfo 方便在之后需要撤销的时候使用 

    NSDictionary *info = [NSDictionary dictionaryWithObject:@"name"forKey:@"key"]; 

    notification.userInfo = info; 

    //添加推送到UIApplication        

    UIApplication *app = [UIApplication sharedApplication]; 

    [app scheduleLocalNotification:notification];  

      

} 

   

第二步：接收本地推送 

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification{ 

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"iWeibo" message:notification.alertBody delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil]; 

    [alert show]; 

    // 图标上的数字减1 

    application.applicationIconBadgeNumber -= 1; 

} 

   

第三步：解除本地推送 

// 获得 UIApplication 

UIApplication *app = [UIApplication sharedApplication]; 

//获取本地推送数组 

NSArray *localArray = [app scheduledLocalNotifications]; 

//声明本地通知对象 

UILocalNotification *localNotification; 

if (localArray) { 

    for (UILocalNotification *noti in localArray) { 

        NSDictionary *dict = noti.userInfo; 

        if (dict) { 

            NSString *inKey = [dict objectForKey:@"key"]; 

            if ([inKey isEqualToString:@"对应的key值"]) { 

                if (localNotification){ 

                    [localNotification release]; 

                    localNotification = nil; 

                } 

                localNotification = [noti retain]; 

                break; 

            } 

        } 

    } 

      

    //判断是否找到已经存在的相同key的推送 

    if (!localNotification) { 

        //不存在初始化 

        localNotification = [[UILocalNotification alloc] init]; 

    } 

      

    if (localNotification) { 

        //不推送 取消推送 

        [app cancelLocalNotification:localNotification]; 

        [localNotification release]; 

        return; 

    } 

}
