代码更新：

.h 文件（TableViewController）：

#import <UIKit/UIKit.h>
#import <iAd/iAd.h>

@interface UITableViewController (UITableViewController) <ADBannerViewDelegate>

@property (strong, nonatomic) ADBannerView *iAD;
@property (nonatomic, assign) BOOL canDisplayBannerAds;

@end

.m 文件（TableViewController）：

#import "UITableViewController+UITableViewController.h"
#import <MessageUI/MessageUI.h>
#import "AppDelegate.h"
#import <iAd/iAd.h>


@implementation UITableViewController (UITableViewController)
@dynamic iAD;

#pragma mark iAd Delegate Methods

-(void)bannerViewDidLoadAd:(ADBannerView *)banner{

[UIView beginAnimations:nil context:nil];

[UIView setAnimationDuration:1];

[banner setAlpha:1];

[UIView commitAnimations];

NSLog(@"iAd loaded");
}

-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error{

[UIView beginAnimations:nil context:nil];

[UIView setAnimationDuration:1];

[banner setAlpha:0];

[UIView commitAnimations];

NSLog(@"iAd donesn't loaded");

self.iAD.hidden = YES;
}

-(void)viewDidLoad{

self.canDisplayBannerAds = YES;
self.iAD.delegate = self;

}

错误：

有人知道我能做什么吗？

Answer 1

你有没有告诉你的班级使用 iAD <ADBannerViewDelegate>？

然后在 ViewDidLoad 中写入：

self.banner.delegate = self;

如上所述，实现ADBannerView的委托方法：

didFailToReceiveAdWithError

Answer 2

确保您将方法命名为 -(void)bannerView:

//in the storyboard, the delegate is set to ViewController

@interface ViewController : UIViewController<ADBannerViewDelegate>
@end

@interface ViewController() 
@property(nonatomic, strong) IBOutlet ADBannerView *adBanner;
@end

@implementation View Controller
- (void)viewDidLoad {
self.adBanner.delegate = self;
}
//this is the working method; note the method name
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
    NSLog(@"banner failed to receive ad with error:%@", error);
    if (self.bannerIsVisible) {
        [self hidesBanner];
    }
}
//this is the non working method; not the method name
//this will never fire because Apples method name is different
- (void)adBannerView:(ADBannerView *)adBanner didFailToReceiveAdWithError:(NSError *)error {
    NSLog(@"banner failed to receive ad with error:%@", error);
    if (self.bannerIsVisible) {
        [self hidesBanner];
    }
}
