iOS程序内进入 App Store 打分的代码

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

　此处的appID是在iTunes Connect创建应用程序时生成的Apple ID

     所以可以用这段代码

        NSString *str = [NSString stringWithFormat: 
                         @"itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa     /wa/viewContentsUserReviews?type=Purple+Software&id=%d", 
                         m_appleID ];  
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
