Dispatches an action message to the specified target.
The action message you want to dispatch.
The target object that defines the specified selector.
YES if either the receiver or its delegate can accept the specified selector; otherwise, NO. This method also returns NO if aSelector is nil.
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 performSelector:withObject: method of NSObject.
