页面不能跳转的bug

[fooval-shen]

guard let currentWindows = self.sharedApplication?.windows else { return nil }
var rootViewController: UIViewController?
for window in currentWindows {
if let windowRootViewController = window.rootViewController {
rootViewController = windowRootViewController
break
}
}

比如在其他window 也有rootViewController的时候， 并且这个时候这个windows 不是key window, 这个时候获取到rootViewControoler 就不是当前 可见的 rootviewController

这里的写法有问题, 正确的写法应该是:
return self.topMost(of: self.sharedApplication?.delegate?.window??.rootViewController)

Does #110 fix this issue?

#110 can NOT fix this issue.

Other Example:
SampleViewController :

let picker = UIImagePickerController()
self?.present(picker, animated: true, completion: nil)

Before present:

<UIWindow: 0x10701a6e0; frame = (0 0; 414 736); gestureRecognizers = <NSArray: 0x2825d4f30>; layer = <UIWindowLayer: 0x282ba4560>>
viewDidLoad() > <example.LightNavigationViewController: 0x107830800>
viewDidLoad() > rootController?.presentedViewController: nil
viewDidLoad() > presentingViewController : nil

After present and Dismiss the UIImagePickerController:

<UIWindow: 0x10701a6e0; frame = (0 0; 414 736); gestureRecognizers = <NSArray: 0x2825d4f30>; layer = <UIWindowLayer: 0x282ba4560>>
<example.LightNavigationViewController: 0x107830800>
rootController?.presentedViewController: Optional(<UIImagePickerController: 0x1078f1e00>)
presentingViewController : nil

So:

/// Returns the top most view controller from given view controller's stack.
open class func topMost(of viewController: UIViewController?) -> UIViewController? {
// presented view controller
if let presentedViewController = viewController?.presentedViewController {
return self.topMost(of: presentedViewController)
}
....

Then topMost will return PUPhotoPickerHostViewController instead SampleViewController.

Can you please share a sample project so that I can reproduce the bug?
