Question

如果我们在解除Google移动广告Splash Interstitial后尝试提供视图，则iOS应用程序会崩溃。

模拟器版本：iOS 7.1（4英寸64位） Google移动广告SDK版本：6.9.2

展示启动广告的代码（应用程序：didFinishLaunchingWithOptions :)：

InitialSlidingViewController *controller = [[InitialSlidingViewController alloc] init];
[self.window setRootViewController:controller];

splashInterstitial_ = [[DFPInterstitial alloc] init];
splashInterstitial_.adUnitID = SplashInterstitialID;
GADRequest *request = [GADRequest request];
splashInterstitial_.delegate = self;
request.testDevices = [NSArray arrayWithObjects:GAD_SIMULATOR_ID, nil];
[splashInterstitial_ loadAndDisplayRequest:request
                               usingWindow:window_
                              initialImage:[UIImage imageNamed:imageName]];

[self.window setBackgroundColor:[UIColor blackColor]];
[self.window makeKeyAndVisible];

使用代理方法

    - (void)interstitial:(DFPInterstitial *)interstitial didFailToReceiveAdWithError:(GADRequestError *)error {
    //present a view
}
- (void)interstitialDidDismissScreen:(GADInterstitial *)ad {
    ad.delegate = nil;
    splashInterstitial_.delegate = nil;
    ad = nil;
    splashInterstitial_ = nil;

    //Present a view controller
}

用于呈现视图的代码

NewViewController *newVC = [[NewViewController alloc] initWithNibName:@"NewViewController" bundle:nil];
    UINavigationController *nav = [[PortraitNavController alloc] initWithRootViewController:newVC];
    nav.navigationBarHidden = YES;
    [self.navigationController presentViewController:nav animated:YES completion:nil];

//从控制台崩溃日志：

* - [GADWebAppViewController isKindOfClass：]：发送到解除分配的实例0x573efe90的消息

通过将用于展示插页式广告的代码移至Rootviewcontroller来解决此问题。建议在Google Ads Developer official blog中使用此解决方案。

//MyRootViewController.m

- (void)viewDidLoad {
    [super viewDidLoad];

    // Remember whether the status bar was hidden or not.
    hideStatusBar_ = [UIApplication sharedApplication].statusBarHidden;

    splashInterstitial_ = [[DFPInterstitial alloc] init];
    splashInterstitial_.adUnitID = SplashInterstitialID;
    splashInterstitial_.delegate = self;

    GADRequest *request = [GADRequest request];
    request.testDevices = [NSArray arrayWithObjects:GAD_SIMULATOR_ID, nil];
    [splashInterstitial_ loadRequest:request];
}

#pragma mark - splashInterstitial delegate methods

- (void)restoreController {
    if (imageView_ != nil) {
        [imageView_ removeFromSuperview];
    }
    [UIApplication sharedApplication].statusBarHidden = hideStatusBar_;
}

- (void)interstitialDidReceiveAd:(GADInterstitial *)ad {

    [splashInterstitial_ presentFromRootViewController:self];
}

- (void)interstitial:(DFPInterstitial *)interstitial didFailToReceiveAdWithError:(GADRequestError *)error {

    [self restoreController];
}

- (void)interstitialWillDismissScreen:(GADInterstitial *)ad {
    [self restoreController];
}

- (void)interstitialDidDismissScreen:(GADInterstitial *)ad {
    //Dismiss Delegate
}

imageView_是一个全屏图像视图，包含相同的闪屏图像。

在关闭Google移动广告Splash非页内广告后，在呈现视图控制器时崩溃
