标题: ios - 关闭 Google Mobile Ads Splash Interstitial 后呈现 View Controller 时崩溃

如果我们在关闭 Google 移动广告后尝试呈现 View ，iOS 应用会崩溃 Splash Interstitial .

模拟器版本:iOS 7.1(4寸64位) 谷歌移动广告 SDK 版本:6.9.2

展示初始广告的代码(application: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];

使用的委托(delegate)方法

    - (void)interstitialDFPInterstitial *)interstitial didFailToReceiveAdWithErrorGADRequestError *)error {
    //present a view
}
- (void)interstitialDidDismissScreenGADInterstitial *)ad {
    ad.delegate = nil;
    splashInterstitial_.delegate = nil;
    ad = nil;
    splashInterstitial_ = nil;

    //Present a view controller
}

用于呈现 View 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];

//来自控制台的崩溃日志:

* -[GADWebAppViewController isKindOfClass:]: message sent to deallocated instance 0x573efe90

Best Answer-推荐答案

通过将用于呈现插页式广告的代码移至 Rootviewcontroller 解决了这个问题。 Google Ads Developer official blog 中推荐此解决方案.

//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)interstitialDidReceiveAdGADInterstitial *)ad {

    [splashInterstitial_ presentFromRootViewController:self];
}

- (void)interstitialDFPInterstitial *)interstitial didFailToReceiveAdWithErrorGADRequestError *)error {

    [self restoreController];
}

- (void)interstitialWillDismissScreenGADInterstitial *)ad {
    [self restoreController];
}

- (void)interstitialDidDismissScreenGADInterstitial *)ad {
    //Dismiss Delegate
}

imageView_ 是一个全屏 ImageView ，包含相同的初始屏幕图像。
