tryToPerform(_:with:)
Dispatches an action message to the specified target.
Declaration
func tryToPerform(_ action: Selector, with object: Any?) -> BoolParameters
- action:
The action message you want to dispatch.
- object:
The target object that defines the specified selector.
Return Value
true if either the receiver or its delegate can accept the specified selector; otherwise, false. This method also returns false if aSelector is nil.
Discussion
The receiver tries to perform the method aSelector using its inherited tryToPerform(_:with:) method of NSResponder. If the receiver doesn’t perform aSelector, the delegate is given the opportunity to perform it using its inherited perform(_:with:) method of NSObject.
