Is there a way to print SEL action?

Question

For example, I want to trace the actions sent to my canPeformAction and they are too numerous to display at each occurrence with a "hover" in the debugger. Therefore, I want to trace to the log and examine it after my test cycle.

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
    NSLog(@"%s: sender=%@", __FUNCTION__, sender, action);
}

Answer 1

You want

NSLog(@"%s: sender=%@, selector=%s", __FUNCTION__, sender,sel_getName(action));

Answer 2

Use NSStringFromSelector to easily get a printable name of the Selector.

NSStringFromSelector(action)

NSString * NSStringFromSelector ( SEL aSelector );

Returns a string representation of a given selector.

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
    NSLog(@"Action: %@", NSStringFromSelector(action));
}
