Uniquely figuring out views – The.Swift.Dev.

First method: accessibility to the rescue!

Lengthy story quick, I used to be fairly bored with tagging views with silly quantity values, so I regarded for a greater different resolution to repair my downside. Because it turned out, there’s a property referred to as accessibilityIdentifier that may do the job.

extension UIView {

    var id: String? {
        get {
            return self.accessibilityIdentifier
        }
        set {
            self.accessibilityIdentifier = newValue
        }
    }

    func view(withId id: String) -> UIView? {
        if self.id == id {
            return self
        }
        for view in self.subviews {
            if let view = view.view(withId: id) {
                return view
            }
        }
        return nil
    }
}

I made a easy extension across the UIView class, so now I can use a correct string worth to uniquely establish any view object within the view hierarchy. It is fairly a pleasant resolution, now I can identify my views in a very nice means. As a free of charge storing the identify beneath the accessibilityIdentifier will profit your UI assessments. 😉

Second method: utilizing enums

The principle thought is to have an Int based mostly enum for each view identifier, so mainly you need to use the tag property to retailer the enum’s rawValue. It is nonetheless not so good because the one above, but it surely’s far more secure than counting on pure integers. 😬

enum ViewIdentifier: Int {
    case submitButton
}

extension UIView {

    var identifier: ViewIdentifier? {
        set {
            if let worth = newValue {
                self.tag = worth.rawValue
            }
        }
        get {
            return ViewIdentifier(rawValue: self.tag)
        }
    }

    func view(withId id: ViewIdentifier) -> UIView? {
        return self.viewWithTag(id.rawValue)
    }
}

Truthfully I simply got here up with the second method proper after I copy & pasted the primary snippet to this text, however what the heck, perhaps another person will prefer it. 😂
