此函数因运行时错误而失败:
-[UIWindow viewForFirstBaselineLayout]: unrecognized selector sent to instance 0x7fb9dae257d0
有人遇到过同样的事吗？
UPD:
在iOS 8.1/8.4模拟器上失败.9.3工作正常.
UPD2:
UIWindow创建如下:
window = UIWindow(frame: UIScreen.mainScreen().bounds)
window?.rootViewController = RootViewController.rootVC
window?.makeKeyAndVisible()
