Error：ERROR ITMS-90474: "Invalid Bundle. iPad Multitasking support requires these orientations:

提交app是遇到如下错误：

[objc] view plaincopyprint?

1. ERROR ITMS-90475: "Invalid Bundle. iPad Multitasking support requires launch story board in bundle 'xxxx'."  
2. ERROR ITMS-90474: "Invalid Bundle. iPad Multitasking support requires these orientations: 'UIInterfaceOrientationPortrait,UIInterfaceOrientationPortraitUpsideDown,UIInterfaceOrientationLandscapeLeft,UIInterfaceOrientationLandscapeRight'. Found 'UIInterfaceOrientationPortrait' in bundle 'xxxx'."  

这是由于提交app适配ios9的ipad的分屏导致的，只要如下图操作就可以了
