Question

I want to give scale in and scale out option while taking picture from camera in my new application. Take for example google maps. We can zoom in and out with touch events. Similar should be image scaling. Or there might be a slider which can control scaling of image. But all of this is to be done at the time of taking picture from camera. How to achieve that?

Answer 1

While using UIImagePickerController, you can set

ImagePicker.allowsEditing = YES;

to get a native “move and scale” option after capturing the image.
check this out from documentation:

hope this will help..
