I only need small thumbnail images for contacts, but the camera returns HUGE images with all the megapixels. So my app ends up with memory warnings every time the user takes a photo. That’s bad.
Is there a way to tell the UIImagePickerController what the maximum image size is, so it won’t waste all that memory upfront?
As far as I can tell, you can’t set the quality of images on UIImagePickerController.
If you use AVFoundation and an AVCaptureStillImageOutput you can set the quality. This involves considerably more work though since you’ll need to build the preview and everything yourself.
As long as you make a thumbnail from the big image and don’t keep it around, you don’t need to worry too much about memory used by UIImagePickerController.
