[Camera Plugin] Inconsistency for the Crop Function in iOS and Android

As mentioned in another discussion, the Camera Plugin now allows developers to customize the cropping function for the width and the height. 

For the allowEdit function, it works very well in the Android app, but not in iOS app. To enhance the cropping function, I have changed the width & height TakePictureJS inside the TakePhoto Client logic in CameraPlugin Module to A4 ratio instead of the default square shape. It turns out I can crop the image in A4 shape in my native Android app, but the native iOS app remains square shape as default. 

In Android, the cropping ratio fit with the A4. 

In iOS, the cropping ratio remains square shape as default. 

Does anyone have the solution on this? Any thought would be appreciated.
