Convert UIButton.currentImage to NSString

[fudgie_no1]

Does anyone know how to achieve this? I can check the current image to see if it equals a string, but for the life of me I can't get the currentImage value to NSLog as a string?! Any help would be greatly appreciated.

Just to clarify, I want to get the current image filename from the UIButton (eg "image1.png")

Converting an image to text is a complex issue. Look into OCR software. I'm not sure if there's anything to support it in the SDK or if you would have to write your own. Or did you mean something else?

Thanks but I don't want to convert the image into text. I literally just want to read the image that's on the button (ie "GoButton.PNG")??

Once you create a UIImage from a file you can't check the filename/path. There's no such property on UIImage.

You should store the current image name in your "model" somehow - like saving the string when you set the image - instead of trying to tease it back out of the view.

Really? Why would they make you do more work for something so simple??

I could do it the long way as follows:

if (SquareToCheck.currentImage == [UIImage imageNamed:@"Image1.PNG"]) {
MyImageAsString = @"Image1.PNG";
}

But then i'd have to code it for every image. surely there's a way I can just take the name of the image from the buttons currentimage property??

Yes really. The property currentImage is a UIImage, and it doesn't have a "name" or "path" property.

UIImage

By they way your method of checking if the address of one image is equal to another is dangerous. If a memory warning takes place then imageNamed: may start returning a different address for the same image. It will work some of the time as long as the image remains on the screen or doesn't get deallocated.

Apple doesn't make it easy because a UIButton/UIImage isn't a good place to store data. It should be usind to *display* data from some kind of model.

Hmmm, that does make sense I suppose. It promotes and ensures clean code.

Do you have any suggestions how I could check it otherwise? Would storing the images in an nsmutable array and comparing the UIButton.currentImage against that also be dangerous? The button will always be on the screen. Thanks for your advice.
