iOS 11下亲测可用：
- (void)goAppStoreCommentWithAppId:(NSString *)appId {
NSString *urlString = [NSString stringWithFormat:@"itms-apps://itunes.apple.com/cn/app/id%@?mt=8&action=write-review",appId];
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:urlString]]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
}
}
