I have a UISlider that slides with a range from 0.0 to 1.0.
Out of the box, the slider lets users slide with a really high number of fraction digits, but I only want my users to be able to increment/decrement by .001 for each "tick" up or down of the slider.
Is this possible to set up?
Thank you!
How big is this slider? Even if you've got it spanning the full width of the screen in landscape mode, a change of 0.001 is only about half a pixel. It sounds like you just need to round the slider's value (behind the scenes) to the precision you're after.
What about something extremely simple, for example: A 3 choices slider (with values {0, 1, 2}), with a IBAction and a IBOutlet connected to it.
-(float)roundValue:(float)value{
if(value <= 0.5) return 0;
if(value <= 1.5) return 1;
return 2;
}
-(IBAction)mySliderChanged:(id)sender {
float value = mySliderOutlet.value; // retrieve value via IBOutlet
value = [self roundValue:value];
// Update the slider to 'snap' in final position
[[self mySliderOutlet] setValue:value animated:YES];
}
This should do the trick:
- (void) getSliderValue:(UISlider *)paramSender{
float increment = 0.001;
float newValue = paramSender.value /increment;
paramSender.value = floor(newValue) * increment;
NSLog(@"Current value of slider is %f", paramSender.value);
}
