Question

我无法解决“尝试......其视图不在窗口层次结构中！”当我在Xcode中使用GADInterstitial时。

当我从mainViewController移动到后台并返回我的应用程序时，会出现插页式广告。但是当我从下一个ViewController移动到后台并回到我的应用程序时，插页式广告没有出现并且发生了错误。移动到ViewController的方式是模态的。

以同样的方式，主ViewController - ＆gt;转到nextViewController - ＆gt;移动到mainViewController - ＆gt;转到背景 - ＆gt;回到app（mainViewController） - ＆gt;间隙没有出现。

我该如何解决这个问题？

====================================

AppDelegate.m

- (void)applicationDidBecomeActive:(UIApplication *)application
{    
    NSNotification *n = [NSNotification notificationWithName:@"inst" object:self];

}

mainViewController 和 bViewController

（除了“moveToB”的移动目标外，所有代码都相同）

#import "AdMob.h"

- (void)viewDidLoad{
.
.
//if become active, show interstitial
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
    [nc addObserver:self selector:@selector(showInst) name:@"inst" object:self];    

}

-(void)moveToB{
    bViewController *nextViewController = [[bViewController alloc] initWithNibName: nil bundle: nil];    
    [self presentViewController:nextViewController animated:YES completion:nil];
}

//show interstitial
-(void)showInst{
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0f * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        [[AdMob sharedInstance].interstitial presentFromRootViewController:self];
    });
}

AdMob.m

#import "AdMob.h"

@implementation AdMob

static AdMob *sharedData_ = nil;

+ (AdMob *)sharedInstance{
    @synchronized(self){
        if (!sharedData_) {
            sharedData_ = [[AdMob alloc]init];
        }
    }
    return sharedData_;
}

- (id)init {
    self = [super init];
    if (self) {
        self.interstitial = [self createAndLoadInterstitial];

    }
    return self;
}

- (GADInterstitial *)createAndLoadInterstitial { 
    GADInterstitial *interstitial =
    [[GADInterstitial alloc] initWithAdUnitID:AdMobInsteID];
    interstitial.delegate = self;
    [GADRequest request].testDevices = @[ kGADSimulatorID, @"myID" ];
    [interstitial loadRequest:[GADRequest request]];
    return interstitial;

}

-(void)loadAdMobInste:(UIViewController*)vc rate:(float)rate{

    if ([self.interstitial isReady]) {
        [self.interstitial presentFromRootViewController:vc];
    }

}


- (void)interstitialDidDismissScreen:(GADInterstitial *)interstitial {
    NSLog(@"load");
    self.interstitial = [self createAndLoadInterstitial];
}


@end
