iOS消息推送代碼(iOS不斷更新，稍微有點過時了)

網上有人整理的超詳細的iOS 8之后的推送，附上鏈接： https://www.jianshu.com/p/027120ca9179



實例：
調用方法：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{//注冊通知
    [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge |
     UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];
｝

//實現 類
#pragma mark - RegisterForRemoteNotifications methods
- (void)application:(UIApplication *)application  didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken
{
    //注冊遠方通知，獲得DeviceToken
    NSString *str = [NSString stringWithFormat:@"Device Token=%@",newDeviceToken];
    NSLog(@"%@",str);
}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err
{
    //注冊失敗
    NSString *str = [NSString stringWithFormat: @"Error: %@", err];
    NSLog(@"%@",str);
}


- (void)application:(UIApplication *)application  didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    //收到通知
    NSString *topId = [NSString stringWithFormat:@"%@",
                       [[userInfo objectForKey:@"aps"] objectForKey:@"alert"]];
 
    //清除圖標上的通知記錄條數
    application.applicationIconBadgeNumber = 0;
    
}

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
    //點擊提示框的打開
    application.applicationIconBadgeNumber = 0;
}
