Discover ways to use string primarily based UIView identifiers as a substitute of tags. If you’re bored with tagging views, try these different options.
First strategy: 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 answer to repair my drawback. 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 establish any view object within the view hierarchy. Itโs fairly a pleasant answer, now I can identify my views in a very nice approach. As a free of charge storing the identify underneath the accessibilityIdentifier will profit your UI checks. ๐
Second strategy: utilizing enums
The principle thought is to have an Int primarily based enum for each view identifier, so principally you need to use the tag property to retailer the enumโs rawValue. Itโs nonetheless not so good because the one above, however itโs far more protected than counting on pure integers. ๐ฌ
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 strategy proper after I copy & pasted the primary snippet to this text, however what the heck, perhaps another person will prefer it. ๐
In case you have a greater answer for this drawback, be at liberty to share it with me.
