奇怪的iAd錯誤導致崩潰

Question

由於iAd我得到了一個非常奇怪的崩潰。這裏是調試器輸出：

Answer 1

你確定你已經發布bannerView的委託嗎？我創建了一個名爲「releaseBannerView」的方法。我這樣做，以便我可以「弱」鏈接我的iAd.framework，並且只有在iAd類出現時才調用方法。對於向後的功能非常有效。

- (void)dealloc { 
[super dealloc]; 
[self releaseBannerView]; 
..and.others... 
} 

：

需要時

-(void)releaseBannerView { 
//Test for the ADBannerView Class, 4.0+ only (iAd.framework "weak" link Referenced) 

Class iAdClassPresent = NSClassFromString(@"ADBannerView"); 

//If iOS has the ADBannerView class, then iAds = Okay: 
if (iAdClassPresent != nil) { 

    //If instance of BannerView is Available: 
    if (self.bannerView) { 

     //Release the Delegate: 
     bannerView.delegate = nil; 

     //Release the bannerView: 
     self.bannerView = nil; 
     } 
    } 
} 

然後和我的dealloc方法裏面，我可以僅僅通過調用此方法無出bannerView
