How to get the image name of button in IOS?

I am new to IOS and Objective-C.

I set the image to the button like the following code.

UIButton *modeChangeButton = [[UIButton alloc] initWithFrame:CGRectMake(233, 490, 60, 60)];
[modeChangeButton setImage:[UIImage imageNamed:@"recordmode.PNG"] forState:UIControlStateNormal];

[self.view addSubview:modeChangeButton];

But how to get the image name of the button ?

For example, I want to get the recordmode.PNG...

Thanks in advance.

Get the name of the UIImage in iOS，this is working！

example：

let sender = UIButton(type: .custom)
sender.setImage(UIImage(named: "Item_center_H"), for: .normal)

if let image = sender.image(for: .normal) {
   DDLog(image.assetName)  // Item_center_H

}

code：

@objc public extension UIImage{

    var assetName: String? {
        guard let imageAsset = imageAsset else { return nil }
        return imageAsset.value(forKey:"assetName") as? String
    }
}

You can't. UIImage does not store the name of the image it contains. You have to store the name elsewhere by yourself in relationship to the Button or image.

First Store Your Image Name in a String like

NSString * imageNameString = @"yourImageName.png";

and then

UIButton *modeChangeButton = [[UIButton alloc] initWithFrame:CGRectMake(233, 490, 60, 60)];
[modeChangeButton setImage:[UIImage imageNamed:imageNameString] forState:UIControlStateNormal];

[self.view addSubview:modeChangeButton];

if you want your button image name simply use imageNameString

To set the image name use below code:

[Your_Button setAccessibilityIdentifier:[NSString stringWithFormat:@"%@",imageName]];

Where imageName=@"recordmode.PNG";

And to get the image name

[Your_Button accessibilityIdentifier];
