I would like to upload a photo directly from UIWebView that has a HTML form for file upload. When I click on button I get options to take photo or choose existing. But when I click any of these two options I get
Warning: Attempt to present
<UIImagePickerController: 0x15c15e00>on<UINavigationController: 0x155a2660>whose view is not in the window hierarchy!
Could please anyone can explain me these warning...
Thank you in advance!
It's a bug on iOS 8, that happens when the webview is presented modally.
The only options right now it not to present the webview modally, you can present it with a navigation controller or switching the rootviewcontroller
Here you can read more about the bug and a proposed solution
