Genymotion “Unable to create virtual machine: failed to import ova file”

Deleting the Genymotion cached .ova file, deleting the corrupted deployed image, redownloading the image, and reinstalling it addressed the issue for me.

Note that the deployed images are under: ~/.Genymobile/Genymotion/deployed

the cached ova files are under: ~/.Genymobile/Genymotion/ova

It looks like the problem isn't the UIImage, but rather the NSData. In Cocoa, any copy (or mutableCopy) method returns an object with a +1 retain count, meaning that you own it and are therefore responsible for releasing it.

In your code, you're calling -copy on myg.imageData, but never releasing it. That's a classic example of a memory leak. Here's what I would do to fix it, plus with changing your syntax a bit:

ivar:

UIImage *Moins1;
@property (nonatomic, retain) UIImage *Moins1;

implementation:

NSData * imageData = [myg.imageData copy];
UIImage * ImageAvatar = [[UIImage alloc] initWithData:imageData];
[imageData release];
[self setMoins1:ImageAvatar];
[ImageAvatar release];
