iOS之APP评分实现

APP评分实现有两种方式：跳转到App Store进行评分和APP内评分

1.跳转到App Store进行评分

ps:appid可在iTunes connect里面查询

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?id=APPID&pageNumber=0&sortOrdering=2&type=Purple+Software&mt=8"]];

2.在自己app内，内置App Store评分。苹果提供了一个框架StoreKit.framework,导入StoreKit.framework,在需要跳转的控制器里面添加头文件#import, 实现代理方法：< SKStorePRoductViewControllerDelegate >

//加载App Store评分控制器
- (void)setUpAppStoreController
{
    // 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;
    [storeProductViewContorller loadProductWithParameters: @{SKStoreProductParameterITunesItemIdentifier: kAppId} completionBlock:^(BOOLresult,NSError*error)   {
       if(error)  {
           NSLog(@"error %@ with userInfo %@",error,[erroruserInfo]);
       }else{
    // 模态弹出App Store评分控制器

    [self presentViewController:storeProductViewContorller animated:YEScompletion:nil];
       }
    }];
}

//监听App Store取消按钮点击
- (void)productViewControllerDidFinish:(SKStoreProductViewController*)viewController
{
    [self dismissViewControllerAnimated: YES completion: nil];
}
