iOS 轉跳到 AppStore 為應用評分

方法一：直接跳到商店NSString *str = [NSString stringWithFormat:@"itms-apps://itunes.apple.com/app/id1071190903"];[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];方法二：載入一個商店控制器//自訂方法- (void)loadAppStoreController {    // 初始化控制器    SKStoreProductViewController *storeProductViewContorller = [[SKStoreProductViewController alloc] init];    // 設定代理請求為當前控制器本身    storeProductViewContorller.delegate = self;    [storeProductViewContorller loadProductWithParameters:@{SKStoreProductParameterITunesItemIdentifier:@"1071190903"} completionBlock:^(BOOL result, NSError *error) {        if (error) {            NSLog(@"error %@ with userInfo %@",error,[error userInfo]);        }else {            // 模態彈出appstore            [self presentViewController:storeProductViewContorller animated:YES completion:^{            }];        }    }];}//AppStore取消按鈕監聽- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController {    [self dismissViewControllerAnimated:YES completion:^{    }];}
