NSLevelIndicator: detect click and update

I want to use a NSLevelIndicator to manage ratings in my apps but I don' t understand how to detect click on it and update the ratings.

This is the code: the property rate is created in the .h file and it's an IBOutlet correctly linked in IB. 

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{

    NSLevelIndicatorCell *cell = [[NSLevelIndicatorCell alloc] initWithLevelIndicatorStyle:NSRatingLevelIndicatorStyle];

    [cell setMinValue:0.0];
    [cell setMaxValue:5.0];

    [cell setFloatValue:3.0];

    [cell setTarget:self];

    [cell setAction:@selector(click:)];

    [self.rate setCell:cell];


}

- (IBAction)click:(id)sender
{

    //How to detect change in rating here???

}

Solution

  • I post the solution for other people with the same "issue".

    The reason why the user interaction not works for me is because i need to call [cell setEnabled:YES]. Probably this property is set to NO by default.
