can I set UIButton a tag with letter？-CodePudding

I encountered a puzzle. I have many buttons. I want to set tag for them respectively, but it seems that tag can only be set as a number, which is inconvenient for me to read the code. I want to set a name similar to “abc”. Is there any way or other way

You can create your own property like this

extension UIButton {
    private struct AssociatedKeys {
        static var stringTag = "stringTag"
    }
    
    @IBInspectable var stringTag: String? {
        get {
            guard let stringTag = objc_getAssociatedObject(self, &AssociatedKeys.stringTag) as? String else {
                return nil
            }
            
            return stringTag
        }
        
        set(value) {
            objc_setAssociatedObject(self, &AssociatedKeys.stringTag, value, objc_AssociationPolicy.OBJC_ASSOCIATION_RETAIN_NONATOMIC)
        }
    }
}

No, tag is integer type

var tag: Int { get set }

If you must want a string tag then you can use custom UIButton with extra variable that is string or character. Like this-

class CustomButton: UIButton {
    var customTag:String = ""
}
