第二种方式
先导入StoreKit.framework
//初始化控制器
SKStoreProductViewController *storeProductViewContorller = [[SKStoreProductViewController alloc] init];
//设置代理请求为当前控制器本身
storeProductViewContorller.delegate = self;
//加载一个新的视图展示
[storeProductViewContorller loadProductWithParameters:
//appId唯一的
@{SKStoreProductParameterITunesItemIdentifier : APP_ID} completionBlock:^(BOOL result, NSError *error) {
//block回调
if(error){
NSLog(@"error %@ with userInfo %@",error,[error userInfo]);
}else{
//模态弹出appstore
[self presentViewController:storeProductViewContorller animated:YES completion:^{
}
];
}
}]
//代理事件
#pragma mark-SKStoreProductViewControllerDelegate
- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController{
[self dismissViewControllerAnimated:YES completion:^{
}];
}
