You can do like this.

[mySlider setMaximumValue:3.0];
[mySlider setContinuous:YES];
[slider addTarget:self action:@selector(sliderChangedAction:) forControlEvents:UIControlEventValueChanged];


- (IBAction)sliderChangedAction:(id)sender {
    UISlider * mySlider = (UISlider*)sender;    
    [mySlider setValue:ceilf(mySlider.value)];

}
