如何实现AdBannerview和ADBannerview委托

Question

我在实现ADBannerView和它的委托协议时遇到了麻烦。

我在我的视图类中实现了以下代码(也使视图符合ADBannerViewDelegate协议)：

//add iAds
ADBannerView *adView = [[ADBannerView alloc] initWithFrame: CGRectMake(0, 318, 320, 50)];
adView.requiredContentSizeIdentifiers = [NSSet setWithObjects: ADBannerContentSizeIdentifierPortrait, ADBannerContentSizeIdentifierLandscape, nil];
adView.delegate = self; 
//adView.delegate = ADBannerViewDelegate;
[self.view addSubview: adView];

然后，我使用以下.m为ADBannerViewDelegate创建了一个类

//
//  ADBannerViewDelegate.m
//

#import "ADBannerViewDelegate.h"

@implementation ADBannerViewDelegate

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error{
    NSLog(@"bannerview did not receive any banner due to %@", error);}

- (void)bannerViewActionDidFinish:(ADBannerView *)banner{NSLog(@"bannerview was selected");}

- (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave{return willLeave;}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner {NSLog(@"banner was loaded");}

@end

横幅最终会显示出来，但控制台会不断抛出以下类型的错误：

2011-02-27 15:00:54.108 app[31639:207] ADBannerView: Unhandled error (no delegate or delegate does not implement didFailToReceiveAdWithError:): Error Domain=ADErrorDomain Code=5 "The operation couldn’t be completed. Banner view is visible but does not have content" UserInfo=0x6356a40 {ADInternalErrorCode=5, NSLocalizedFailureReason=Banner view is visible but does not have content}

而委托函数没有做任何事情，所以根本就没有NSLog。显然没有捕捉到错误。

我被难住了。我猜我在视图和委托中的Adbanner视图调用的链接中遗漏了一些东西。不知道该怎么做，也不知道哪里出了问题。

有什么帮助吗？提前谢谢。

Answer 1

原因是你告诉AdBannerView你是它的代表，但你从来没有把它放在你的实现文件中。您的实现文件应如下所示(请注意包含@implmentation的行)：

//
//  ADBannerViewDelegate.m
//

#import "ADBannerViewDelegate.h"

@implementation ADBannerViewDelegate<ADBannerViewDelegate>

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error{
    NSLog(@"bannerview did not receive any banner due to %@", error);}

- (void)bannerViewActionDidFinish:(ADBannerView *)banner{NSLog(@"bannerview was selected");}

- (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave{return willLeave;}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner {NSLog(@"banner was loaded");}

@end

而且你也不应该把你的类命名为ADBannerViewDelegate.您的类应该是ADBannerView的委托(响应它)，而不是根据它命名。

我使用这个教程在我的应用程序中成功地集成了iAds：

也许对你也有帮助。

您不必尝试实现一个名为ADBannerViewDelegate的类，而是将这些方法放在视图类的实现中。

(如果您实际将视图类命名为"ADBannerViewDelegate"，请不要这样做，因为这会让人感到困惑。)
