Easily way to write a control logic for call once function in instance.
Usage
To support call once, a class needs to implement the OnceType
class ViewController: UIViewController, OnceType {
override func viewDidLoad() {
super.viewDidLoad()
}
}You can use once property. And once using call() method.
call() is called only sometimes in same function.
func anyFunction() {
once.call() {
print("This statement is call once while self live")
}
once.call() {
fatalError("Not call this statemenet")
}
}If want to call once again. You should call clearAll() method.
clearAll() is clear all cache. You can same call() one more time.
func callOneMoreTime() {
once.clearAll()
anyFunction() // <- This statement is call once while self live
}It's also possible to control call() with string key.
And you can use clear(withKey: String) method.
func callingWithKey() {
once.call("key") {
print("Calling")
}
once.call("key") {
fatalError("Not Call")
}
once.call() {
print("Calling")
}
once.clear(withKey: "key")
once.call("key") {
print("Calling")
}
once.call() {
fatalError("Not Call")
}
