Question

我正在尝试使用Tapjoy为我的应用程序，我正在使用以下代码

-(void)getTapJoyAd{
    [Tapjoy getFullScreenAd];

    // A notification method must be set to retrieve the fullscreen ad object.
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(getFullScreenAd:)
                                                 name:TJC_FULL_SCREEN_AD_RESPONSE_NOTIFICATION
                                               object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(fullscreenAdClosed:)
                                                 name:TJC_VIEW_CLOSED_NOTIFICATION
                                               object:nil];

    // This method requests the tapjoy server for current virtual currency of the user.
    [Tapjoy getTapPoints];
    // A notification method must be set to retrieve the points.
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getUpdatedPoints:) name:TJC_TAP_POINTS_RESPONSE_NOTIFICATION object:nil];
}

问题是当我再次回想起这个方法时，它会一起打开两个屏幕.. 我称之为这种方法越多，屏幕就会越多......

基本上问题是你的notification被观察了多少次然后你的方法正在执行。因此，一旦发布并notification notification observer，就可以阻止此问题，然后移除您的notification。此外，它还取决于您的代码，以及您如何处理remove observer部分。因此，请尝试-(void)viewDidDisappear:(BOOL)animated { [[NSNotificationCenter defaultCenter]removeObserver:self name:TJC_FULL_SCREEN_AD_RESPONSE_NOTIFICATION object:nil]; [[NSNotificationCenter defaultCenter]removeObserver:self name:TJC_VIEW_CLOSED_NOTIFICATION object:nil]; [[NSNotificationCenter defaultCenter]removeObserver:self name:TJC_TAP_POINTS_RESPONSE_NOTIFICATION object:nil]; }并查看以下内容： -
