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

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。
