NSClickGestureRecognizer *click = [[NSClickGestureRecognizer alloc] initWithTarget:self action:@selector(myTextFieldClicked:)];
[self.myTextField addGestureRecognizer:click];

你可以试试这个:它适合我.

    @interface customTextField : NSTextField
    @property (strong) id target;
    @end

    @implementation customTextField

    - (void)mouseDown:(NSEvent *)theEvent
    {
        [self sendAction:@selector(clickAction:) to:[self target]];
    }

    @end

谢谢.
