需要删除一个子视图

Question

我正在使用此调用横幅;

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

它从AdManager.m文件中调用;

- (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; 
} 

这很好，不过，我需要停止出现在某一点（如购买）这个观点，我现在有一个NSNotification集，在购买时，隐藏的旗帜，我就是” t似乎隐藏它！

我想这将是一个设置从超级视图中删除视图的情况，但似乎无法找到正确的方式。

在添加之前存储对您的视图的引用。

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

再后来，你可以使用：

[self.adBanner removeFromSuperView]; 

除非我失去的东西，就是你应该需要做的。
