How to get Image Name used in an UIImage?

Question

I am using an UIImage, in which I have an Image, and I want to know the name of image.

Solution 1

That functionality is not built-in to UIImage because images are not always loaded from files. However, you could create a custom UIImageView subclass to fit your needs.

Solution 2

It is not possible. UIImage instance contains the actual image data without any reference to the filename.

Solution 3

this code will help you out

    NSString *imgName = [self.imgView1st image].accessibilityIdentifier;

    NSLog(@"%@",imgName);

    [self.imgView2nd setImage:[UIImage imageNamed:imgName]];

Solution 4

Images do not necessarily come from files or other named sources, so not all images even have a name. When you create an image from a file, you could store the name in a separate NSString*, and then refer to that stored name when necessary.

@JayD: Not directly from an instance of UIImage.

this doesn't work because you have to set the accesibiliyIdentifier when assining image

This is definitely the right answer! People should upvote it. When loading images via local bundle, using XCAssets, the runtime itself will automatically assign the accessibilityIdentifier to be the same as the asset name. When loading images dynamically or creating it dynamically, of course there is no built-in solution

Wrong, @junaidsidhu has nailed it corretly

The accessibilityIdentifier is exposed only when accessibility is enabled on the device. This might be the case that it works for you in development on the simulator, but won't work on actual user's device.
