How can I get the file path from a UIImage?

Question

Usually it\'s the other way around, you use the path to display the image. I was wondering if you can get the path if you already have the image.

I don't believe it is possible to get it directly from UIImage.

Best way is to save the image in a directory, then you will have the file path.

//image is your UIImage;

if (image != nil)
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                         NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString* path = [documentsDirectory stringByAppendingPathComponent:
                      @"test.png" ];
    NSData* data = UIImagePNGRepresentation(image);
    [data writeToFile:path atomically:YES];
}

path will be your filepath.
