Failed to instantiate the default view controller for UIMainStoryboardFile 'MyMain' - perhaps the designated entry point is not set?
自己新建了一个MyMain.storyboard,使用时报了一个错误如下:

原因分析:StoryBoard中没有一个view controller设置了Initial Scene。
解决方法:需要选择一个view conroller作为story board的第一个界面。将右边View Controller下的Is Initial View Controller的单选框勾上。
