I'm trying to save a UIImageView image to a png file, and then use that file as a GLTexture. I'm having trouble with this, when I try to run my code in the simulator, XCode says it succeeded, but the simulator crashes with no error messages. Can someone help me with this? Here is my code:

NSString *dataFilePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Picture.png"];

NSData *imageData = UIImagePNGRepresentation(imageView.image); [imageData writeToFile:dataFilePath atomically:YES];

// Load image into texture loadTexture("Picture.png", &Input, &renderer);
