Learn to use string primarily based UIView identifiers as a substitute of tags. If you’re uninterested in tagging views, try these various options.
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 resolution 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 determine any view object within the view hierarchy. It’s fairly a pleasant resolution, now I can title my views in a very nice means. As a free of charge storing the title underneath the accessibilityIdentifier will profit your UI checks. 😉
Second strategy: utilizing enums
The primary concept is to have an Int primarily based enum for each view identifier, so principally you should utilize 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 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 strategy proper after I copy & pasted the primary snippet to this text, however what the heck, perhaps another person will prefer it. 😂
In case you have a greater resolution for this drawback, be at liberty to share it with me.
