app 评分的两种方法

给app进行评分有两种方法：都是直接跳到app store 给app进行评分的，具体请看下文：

1.App Store 上评论的链接地址是 ：//（1）itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id = appID 替换成：

itms-apps://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=appID在iOS7上就行了！

                                                     （2）itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?mt=8&onlyLatestVersion=true&pageNumber=0&sortOrdering=1&type=Purple+Software&id=appID 替换成 ：

itms-apps://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?mt=8&onlyLatestVersion=true&pageNumber=0&sortOrdering=1&type=Purple+Software&id=appID

 

具体代码如下：

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?mt=8&onlyLatestVersion=true&pageNumber=0&sortOrdering=1&type=Purple+Software&id=appID"]];

2.在用户给我们的app评分的时候，一般情况下我们都需要跳转到app store，很不方便。在iOS6以后，引入了

SKStoreProductViewController类，可以在应用内展示App Store,用户可以不用离开应用，直接给我们的应用评分或者展示其他的app信息。

       在应用内展示AppStore，需要给项目添加StoreKit.frame. SKStoreProductViewController存在StoreKit框架内。代码如下：

#pragma mark - 应用内评论
- (void)openAppStore
{
    SKStoreProductViewController * storeProductViewController = [[SKStoreProductViewController alloc] init];
    [storeProductViewController setDelegate:self];
    [storeProductViewController loadProductWithParameters:@{SKStoreProductParameterITunesItemIdentifier:@"appID"} completionBlock:^(BOOL result, NSError *error) {
        
        if(error) {
            
            NSLog(@"Error %@ with user info %@",error,[error userInfo]);
            
        } else {
            
            [self presentViewController:storeProductViewController animated:YES completion:nil];
        }
    }];

    [storeProductViewController release];

}

#pragma mark - SKStoreProductViewControllerDelegate

-(void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController
{
    [self dismissViewControllerAnimated:YES completion:nil];
}
