针对Objective-C的iOS Admob非页内广告

Question

我已经在viewDidLoad上实现了插页式广告，但是我需要与此相关的帮助。 我希望Interstitial不会在每次出现viewDidLoad时都显示，例如，我希望它一次显示一次，一次不显示。

• 案例1展示
• 情况2不显示
• 案例3展示
• ......

这是我的代码：

 - (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    self.interstitial = [[GADInterstitial alloc] initWithAdUnitID:@"a151b7d316a5c1d"];
    self.interstitial.delegate = self;
    [self.interstitial loadRequest: [GADRequest request]];
}
- (void)interstitialDidReceiveAd:(GADInterstitial *)interstitial {
    [interstitial presentFromRootViewController:self];
}

我对广告进行相同的一对一的处理。 我只是使用用户默认值来保存计数器。 也许尝试以下方法。 下面的代码写得很清楚，所以有点长，但是一旦知道它在做什么，就可以进入并拧紧它（例如，使用adCount += 1;而不是adCount = adCount + 1;等等。希望如此）帮助！

- (void)viewDidLoad
{
    [super viewDidLoad];

    //Call to your helper method
    //Stop viewDidLoad here if the method returns NO

    if (![self _shouldShowInterstitial]) return;

    self.interstitial = [[GADInterstitial alloc];
    initWithAdUnitID:@"a151b7d316a5c1d"];
    self.interstitial.delegate = self;
    [self.interstitial loadRequest: [GADRequest request]];
}

- (BOOL)_shouldShowInterstitial
{
    //1. Recover user default holding a counter
    BOOL retVal = NO;
    NSString *adKey = @"shouldShowInterstitialOnLoadDefaultKey";
    NSInteger adCount = [[NSUserDefaults standardUserDefaults]integerForKey:adKey];

    //2. If the counter is 1, return YES for showing an ad and reset the count to 0
    if (adCount > 0) {
        retVal = YES;
        adCount = 0;

    //3. If the count is 0, no ad is required, but increment it so next time the ad will show
    } else {
        retVal = NO;
        adCount = adCount + 1;
    }

    //4. Save your defaults
    [[NSUserDefaults standardUserDefaults] setInteger:adCount forKey:adKey];
    [[NSUserDefaults standardUserDefaults] synchronize];

    //5. Return your bool value
    return retVal;
}
