Answer 1

You should first make sure the updates event are sent continuously:

mySlider.continuous = YES;

You can also do that in your storyboard/nib (as mentionned by @fDmitry, this is the default state in IB).

Then you have to link your slider to an IBAction in your .h file (create a link by ctrl-dragging from IB to your code), and assign it to the "Value Changed" event of your slider. This will create a method like this:

-(IBAction)sliderValueChanged:(id)sender;

Implement it that way:

- (IBAction)sliderValueChanged:(id)sender {

    float maxValue = 50.0f;

    if ([(UISlider*)sender value] > maxValue) {
        [(UISlider*)sender setValue:maxValue];
    }
}
