change NSSlider Value programmatically

问题

Is there a way to make an IBOutlet of an NSSlider and then be able to change its value programmatically? slider.value = ...does not work.

Thanks!

回答1:

You can use the methods of NSControl.

Example: [self.slider setDoubleValue:0.1];

Swift answer to this question is to use the doubleValue property to access the slider value in OSX:

slider.doubleValue = 0.1 

print(slider.doubleValue)
