Rams1 Answer
Try dismissing the picker and releasing it after you retrieve the image taken from the camera.
Besides, if the camera is not available, you're leaking memory by creating the imagepicker and not releasing it in case of an error.
Create the UIImagePickerController autoreleased and don't release it in the imagePickerController:didFinishPickingMediaWithInfo: method, just dismiss it at the end.
The other problem is that in addition to the UIImage holding the original image, you're creating a scaled down one and a thumbnail. Memory pressure may be high in this situation so you should get rid of the images from the memory as soon as possible, especially when you're trying to upload the image right after it's picked so surely the underlying network framework (whatever you're using) is creating another chunk of memory representing the image to be uploaded.
Try to separate the process of picking the image, creating a scaled down and a thumbnail and uploading it by moving those parts of code to separate steps of an NSOperationQueue.
- Retrieve the image from the picker and store it to "disk". Release the memory related to the PickerController.
- Get the image from disk, create a thumbnail and a scaled down version, store those to disk. Clean up the memory.
- Get the scaled down image from disk and upload it.
Don't do everything in the main thread, because your app will get killed by the runtime if it blocks the UI for too long.
