需要刪除一個子視圖

Question

我正在使用此調用橫幅;

[self.view addSubview:[[AdManager sharedInstance] adMobBanner]]; 

它從AdManager.m文件中調用;

- (GADRequest *)adMobrequest { 
    GADRequest *request = [GADRequest request]; 
    request.testDevices = @[ 
          // TODO: Add your device/simulator test identifiers here. Your device identifier is printed to 
          // the console when the app is launched. 
          GAD_SIMULATOR_ID, 
          ]; 
    return request; 
} 

-(GADBannerView*)adMobBannerWithAdUnitID:(NSString*)adUnitID{ 
    GADBannerView *bannerView = [[GADBannerView alloc] initWithAdSize:GADAdSizeFromCGSize(CGSizeMake([UIScreen mainScreen].bounds.size.width, AdmobBannerHeight)) origin:CGPointMake(0, 
                                                [UIScreen mainScreen].bounds.size.height -AdmobBannerHeight)]; 
    bannerView.adUnitID = adUnitID; 
    NSString *sourceString = [[NSThread callStackSymbols] objectAtIndex:1]; 
    // Example: 1 UIKit        0x00540c89 -[UIApplication _callInitializationDelegatesForURL:payload:suspended:] + 1163 
    NSCharacterSet *separatorSet = [NSCharacterSet characterSetWithCharactersInString:@" -[]+?.,"]; 
    NSMutableArray *array = [NSMutableArray arrayWithArray:[sourceString componentsSeparatedByCharactersInSet:separatorSet]]; 
    [array removeObject:@""]; 

    bannerView.rootViewController = [array objectAtIndex:3]; 
    [bannerView loadRequest:[[AdManager sharedInstance] adMobrequest]]; 

    return bannerView; 
} 


-(GADBannerView*)adMobBanner{ 
    GADBannerView *bannerView = [[GADBannerView alloc] initWithAdSize:GADAdSizeFromCGSize(CGSizeMake([UIScreen mainScreen].bounds.size.width, AdmobBannerHeight)) origin:CGPointMake(0, 
                                                [UIScreen mainScreen].bounds.size.height -AdmobBannerHeight)]; 
    bannerView.adUnitID = ADMOB_BANNER_ID; 
    NSString *sourceString = [[NSThread callStackSymbols] objectAtIndex:1]; 
    // Example: 1 UIKit        0x00540c89 -[UIApplication _callInitializationDelegatesForURL:payload:suspended:] + 1163 
    NSCharacterSet *separatorSet = [NSCharacterSet characterSetWithCharactersInString:@" -[]+?.,"]; 
    NSMutableArray *array = [NSMutableArray arrayWithArray:[sourceString componentsSeparatedByCharactersInSet:separatorSet]]; 
    [array removeObject:@""]; 

    bannerView.rootViewController = [array objectAtIndex:3]; 
    [bannerView loadRequest:[[AdManager sharedInstance] adMobrequest]]; 

    return bannerView; 
} 

-(GADBannerView*)adMobBannerWithAdUnitID:(NSString*)adUnitID andOrigin:(CGPoint)origin 
{ 

    GADBannerView *bannerView = [[GADBannerView alloc] initWithAdSize:GADAdSizeFromCGSize(CGSizeMake([UIScreen mainScreen].bounds.size.width, AdmobBannerHeight)) origin:origin]; 
    bannerView.adUnitID = adUnitID; 
    NSString *sourceString = [[NSThread callStackSymbols] objectAtIndex:1]; 
    // Example: 1 UIKit        0x00540c89 -[UIApplication _callInitializationDelegatesForURL:payload:suspended:] + 1163 
    NSCharacterSet *separatorSet = [NSCharacterSet characterSetWithCharactersInString:@" -[]+?.,"]; 
    NSMutableArray *array = [NSMutableArray arrayWithArray:[sourceString componentsSeparatedByCharactersInSet:separatorSet]]; 
    [array removeObject:@""]; 

    bannerView.rootViewController = [array objectAtIndex:3]; 
    [bannerView loadRequest:[[AdManager sharedInstance] adMobrequest]]; 

    return bannerView; 
} 

這很好，不過，我需要停止出現在某一點（如購買）這個觀點，我現在有一個NSNotification集，在購買時，隱藏的旗幟，我就是」 t似乎隱藏它！

我想這將是一個設置從超級視圖中刪除視圖的情況，但似乎無法找到正確的方式。

在添加之前存儲對您的視圖的引用。

self.adBanner = [[AdManager sharedInstance] adMobBanner]; 
[self.view addSubview:self.adBanner]; 

再後來，你可以使用：

[self.adBanner removeFromSuperView]; 

除非我失去的東西，就是你應該需要做的。
