ios App内部弹出AppStore下载界面

1,导入#StoreKit/StoreKit.h 库

#import <StoreKit/StoreKit.h>

2,遵守SKStoreProductViewControllerDelegate协议

3,使用如下代码 其中900089067为app在App Store中的id号

SKStoreProductViewController *store = [[SKStoreProductViewController alloc] init];

    store.delegate = self;

    NSDictionary *dic = [NSDictionary dictionaryWithObject:@"900089067" forKey:SKStoreProductParameterITunesItemIdentifier];

    [store loadProductWithParameters:dic completionBlock:^(BOOL result, NSError * _Nullable error) {

        if (!error) {

            [self presentViewController:store animated:YES completion:nil];

        }

        else {

            NSLog(@"ERROR:%@", error);

        }

    }];

4实现代理

- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController{

    [viewController dismissViewControllerAnimated:YES completion:nil];

}

完美成功
