APP 审核被拒 umeng 分享问题

收到APP审核被拒如下：

We noticed an issue in your app that contributes to a lower quality user experience than Apple users expect: 

- Upon tapping the QQ button from the share menu, a web page in mobile Safari opens first, then returns to the app. The user should be able to use the app immediately
upon launch. 

在使用UMENG QQ分享时，若未安装QQ，点击QQ分享按钮时，会调到safari浏览器

其实umeng官方SDK文档中有这一建议。。。



即在未安装应用时，不显示相关分享按钮。就规避这种情况
