Uniquely figuring out views – The.Swift.Dev.

First strategy: accessibility to the rescue!

Lengthy story quick, I used to be fairly uninterested in tagging views with silly quantity values, so I seemed for a greater various answer 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 determine any view object within the view hierarchy. It’s fairly a pleasant answer, now I can identify my views in a very nice manner. As a free of charge storing the identify below the accessibilityIdentifier will profit your UI exams. 😉

Second strategy: utilizing enums

The principle thought is to have an Int based mostly enum for each view identifier, so mainly you should use the tag property to retailer the enum’s rawValue. It’s nonetheless not so good because the one above, but it surely’s far more protected 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)
    }
}

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