Uniquely figuring out views – The.Swift.Dev.


First method: accessibility to the rescue!

Lengthy story brief, I used to be fairly uninterested in tagging views with silly quantity values, so I seemed for a greater different answer to repair my drawback. 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 answer, now I can identify my views in a very nice method. As a free of charge storing the identify below the accessibilityIdentifier will profit your UI exams. 😉

Second method: utilizing enums

The principle concept is to have an Int primarily based enum for each view identifier, so principally you should use the tag property to retailer the enum’s rawValue. It is nonetheless not so good because the one above, however it’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)
    }
}

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, possibly another person will prefer it. 😂
