1、跳转到App Store 直接编辑评论

    NSString *APPID = @"xxxxxxxx";//app ID
    NSString *nsStringToOpen = [NSString stringWithFormat: @"itms-    apps://itunes.apple.com/app/id%@?action=write-review",APPID];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:nsStringToOpen]];

2、app内部直接评分

if (@available(iOS 10.3, *)) {
        if([SKStoreReviewController respondsToSelector:@selector(requestReview)]) {
            //防止键盘遮挡
            [[UIApplication sharedApplication].keyWindow endEditing:YES];
            [SKStoreReviewController requestReview];
            
        }
    }else {
    // Fallback on earlier versions
}

3、跳转到某app下载页面 一般用与打广告

//第一种方式
    NSString *appId = @"xxxxxxxx";
    // 创建对象
    SKStoreProductViewController *storeVC = [[SKStoreProductViewController alloc] init];
    // 设置代理
    storeVC.delegate = self;
    // 初始化参数
    NSDictionary *dict = [NSDictionary dictionaryWithObject:appId forKey:SKStoreProductParameterITunesItemIdentifier];
    // 跳转App Store页
    [storeVC loadProductWithParameters:dict completionBlock:^(BOOL result, NSError * _Nullable error) {
        if (error) {
            NSLog(@"错误信息：%@",error.userInfo);
        }else{
            // 弹出模态视图
            [self presentViewController:storeVC animated:YES completion:nil];
        }
    }];
//第二种方式
    Class allow = NSClassFromString(@"SKStoreProductViewController");
    if (allow != nil && ![[UIDevice currentDevice].model isEqualToString:@"iPhone Simulator"]) {
        NSLog(@"loading");
        SKStoreProductViewController *product = [[SKStoreProductViewController alloc] init];
        product.delegate = self;
        [product loadProductWithParameters:@{SKStoreProductParameterITunesItemIdentifier:@"983122949"} completionBlock:^(BOOL result, NSError * _Nullable error) {
            NSLog(@"completion");
            NSLog(@"--%d-%@",result,error);
            if (!error) {
                [self presentViewController:product animated:YES completion:nil];
            }else{
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@""]];
            }
        }];
    }

#pragma mark -- SKStoreProductViewControllerDelegate
/**
 SKStoreProductViewControllerDelegate 方法，选择完成之后的处理
 @param viewController SKStoreProductViewController
 */
- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController{
    NSLog(@"将要退出 App Store 页面了");
    [viewController dismissViewControllerAnimated:YES completion:^{
        NSLog(@"已经退出 App Store 页面完成了");
    }];
}

4、跳转评论

在iOS 11之前，为了让用户直接跳到App Store的评论页面，你的代码大概是这样写的：

-(void)goToAppStore{
    NSString *itunesurl = @"[http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?id=XXXXXXXX&pageNumber=0&sortOrdering=2&type=Purple](https://links.jianshu.com/go?to=http%3A%2F%2Fitunes.apple.com%2FWebObjects%2FMZStore.woa%2Fwa%2FviewContentsUserReviews%3Fid%3DXXXXXXXX%26pageNumber%3D0%26sortOrdering%3D2%26type%3DPurple)+Software&mt=8";

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:itunesurl]];
}

在iOS 11上不灵了，直接提示“无法连接App Store”！

我试了一下，果然如此，顺便看了一下其他家的APP，不少大厂的APP也掉进了这个坑里还没爬出来，比如饿了么，百度外卖等。经过搜索引擎的帮助，我找到了如下办法：

-(void)goToAppStore{
    NSString *itunesurl = @"itms-[apps://itunes.apple.com/cn/app/idXXXXXX?mt=8&action=write-review](https://links.jianshu.com/go?to=apps%3A%2F%2Fitunes.apple.com%2Fcn%2Fapp%2FidXXXXXX%3Fmt%3D8%26action%3Dwrite-review)";

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:itunesurl]];
}

注意：把里面的XXX替换成你自己的APP ID。 如果不知道 APP ID，打包到appstore 的时候有APP ID

iOS 11 跳转到app设置

NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
[[UIApplication sharedApplication]openURL:url];
