我的实现如下 - 我希望它有所帮助:
@interface ViewController () <GADInterstitialDelegate>
@property (strong, nonatomic) GADInterstitial *interstitial;
@end
@implementation ViewController
#define MY_INTERSTITIAL_UNIT_ID @"...."
- (void)preLoadInterstitial {
//Call this method as soon as you can - loadRequest will run in the background and your interstitial will be ready when you need to show it
GADRequest *request = [GADRequest request];
self.interstitial = [[GADInterstitial alloc] init];
self.interstitial.delegate = self;
self.interstitial.adUnitID = MY_INTERSTITIAL_UNIT_ID;
[self.interstitial loadRequest:request];
}
- (void)interstitialDidDismissScreen:(GADInterstitial *)ad
{
//An interstitial object can only be used once - so it's useful to automatically load a new one when the current one is dismissed
[self preLoadInterstitial];
}
- (void)interstitial:(GADInterstitial *)ad didFailToReceiveAdWithError:(GADRequestError *)error
{
//If an error occurs and the interstitial is not received you might want to retry automatically after a certain interval
[NSTimer scheduledTimerWithTimeInterval:3.0f target:self selector:@selector(preLoadInterstitial) userInfo:nil repeats:NO];
}
- (void) showInterstitial
{
//Call this method when you want to show the interstitial - the method should double check that the interstitial has not been used before trying to present it
if (!self.interstitial.hasBeenUsed) [self.interstitial presentFromRootViewController:self];
}
@end
