ios - NSObject 可能无法响应 'onEnter'(在 AppDelegate 中使用 iAd 时)

Question

使用 iAd。很少收到警告。 下面是我放在 AppDelegate.m 中的代码

缺少什么？

警告在代码行末尾指示

-(void)onEnter
{
    [super onEnter]; //<-- NSObject may not respond to this
    adView = [[ADBannerView alloc]initWithFrame:CGRectZero];
    adView.delegate = self;
    adView.requiredContentSizeIdentifiers = [NSSet setWithObjects: ADBannerContentSizeIdentifierLandscape, ADBannerContentSizeIdentifierLandscape, nil];
    adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
    [[[CCDirector sharedDirector] openGLView] addSubview:adView];
    adView.hidden = YES;
}


-(void)onExit
{
    adView.delegate = nil;
    [adView removeFromSuperview];
    [adView release];
    adView = nil;
    [super onExit]; //<-- NSObject may not respond to this
}



-(void)bannerViewActionDidFinish :(ADBannerView *)banner
    {    
        NSLog(@"bannerViewActionDidFinish called");
        [[UIApplication sharedApplication] setStatusBarOrientation :(UIInterfaceOrientation)[[CCDirector sharedDirector] deviceOrientation]];
    }
//<-- Instance method deviceOrientation not found (return type defaults to id)

怎么了？缺少要继承的任何类？

Answer 1

onEnter 和 onExit 方法仅在从 CCNode 派生的类中可用。您的类是 NSObject 的子类。

如果您手动发送 onEnter/onExit 消息，只需删除对 super onXXX 的调用，因为它是多余的。
