In daily build 2014.2482, this feature was added for iOS: When a keyboard appears, the window will shift upward so that the selected native textfield/textbox sits above the keyboard.
First, is there a way to disable this? For the apps that have already solved this issue in their own ways, it may be problematic to have Corona trying to do this for them.
Second, there are a few bugs in this code. It doesn’t understand or respect the current orientation with regards to how it adjust the window. See the screenshots below of portrait, landscape, and upside down portrait for an example. To reproduce, just simply install the project from SampleApps/Interface/NativeDisplayObjects on an iOS device and activate the keyboard. In my testing, it didn’t appear on every device or iOS version (maybe only limited to iOS 7 on iPad?).
