如何從iOS應用程序中的UIViewController中刪除ADBannerView？

Question

在我的應用程序，我已經通過代碼

在.h文件中

@property (strong, nonatomic) ADBannerView *adBannerView; 

在.m文件添加ADBannerView到UIViewController

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    self.adBannerView = [[ADBannerView alloc] initWithFrame:CGRectMake(0, 518, 320, 50);]; 
    [self.view addSubview:self.adBannerView]; 
} 

#pragma mark - 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 { 
    NSLog(@"banner action should begin"); 
    return YES; 
} 

- (void)bannerViewWillLoadAd:(ADBannerView *)banner { 
    NSLog(@"banner will loaded"); 
} 

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

我的應用程序通常是，它可以顯示ADBannerView。但現在，我想從UIViewController中刪除ADBannerView，然後刪除了有關ADBannerView的所有代碼行。我可以建立我的應用程序，但它不能運行，則錯誤味精是：

Could not instantiate class named ADBannerView 

請幫我刪除ADBannerView。謝謝。

if (!bannerIsVisible){ 
    //LOG_TYPE(@"AD show"); 
    [UIView beginAnimations:@"animateAdBannerOn" context:NULL];

Answer 2

，如果你在故事板添加ADBannerView然後取出ADBannerView的IBoutlet及其delegate。如下圖所示爲ADBannerView

突破連接從腳本移除ADBannerView和你上面的代碼是完美的。

您的錯誤如下。

Answer 3

[self.adView removeFromSuperView];
