First strategy: accessibility to the rescue!
Lengthy story quick, I used to be fairly bored with tagging views with silly quantity values, so I seemed for a greater various 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 approach. As a free of charge storing the identify below the accessibilityIdentifier will profit your UI exams. 😉
Second strategy: utilizing enums
The primary concept is to have an Int based mostly 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 strategy proper after I copy & pasted the primary snippet to this text, however what the heck, perhaps another person will prefer it. 😂
