Question

I’m going through a memory issue using a simple “UIImagePickerController”.
I get two memory warning: one at when I take the image, and one when I touch on the “Use” button…
And the best is, this only append on the 4S (which happen to be my boss’s phone). I’m not even able to reproduce this bug on an other model of iPhone (tested on a 3G, 3GS, 4 and 5).

I tried different things and this is this is the simplest exemple which is able to reproduce the problem:

UIImagePickerController *picker = [[UIImagePickerController alloc] init];

picker.sourceType = UIImagePickerControllerSourceTypeCamera;

picker.delegate = self;

[self presentModalViewController:picker animated:YES];

[picker release];

And I implement the delegate methods:

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
    [picker dismissModalViewControllerAnimated:YES];
}


- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

// should do something with the [[info objectForKey:UIImagePickerControllerOriginalImage] retain];

    if (picker.sourceType == UIImagePickerControllerSourceTypeCamera)
        UIImageWriteToSavedPhotosAlbum(selectedImage, nil, NULL, nil);

    [picker dismissModalViewControllerAnimated:YES];

}

Does anyone know this issue and hopefully the solution?

Thanks a lot!

This is very common. As long as you handle the memory warning without crashing and have enough space to keep going, don’t let it drive…
