Uniquely figuring out views – The.Swift.Dev.



· 1 min learn


Discover ways to use string primarily based UIView identifiers as a substitute of tags. In case you are bored with tagging views, try these different options.

First method: accessibility to the rescue!

Lengthy story brief, 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 known 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 resolution, now I can title my views in a very nice method. As a free of charge storing the title beneath the accessibilityIdentifier will profit your UI assessments. 😉

Second method: utilizing enums

The primary concept is to have an Int primarily based 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, however it’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)
    }
}

Actually 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. 😂

When you’ve got a greater resolution for this downside, be at liberty to share it with me.
