Question

i need to get the current value of a UISlider and put it into a variable.
my UISlider name is searchRadiusSlider and i want that the value will be %.0f.

i could display it as a String like that :

[NSString stringWithFormat:@"%.0f", [(UISlider *)sender value]];

but for my case, i want simply to get it as numeric :

self.searchRadius= //what to put here

Thx in advance 🙂

If you want to drop the decimals just cast to int and this will truncate the decimals.

self.searchRadius =
(int)searchRadiusSlider.value;

If you want to round the decimals like %.0f use round() from math.h (Not exactly, %.0f uses banker’s rounding whereas round() uses half up rounding so 2.5 is rounded to 2 in the former and 3 in the later)

self.searchRadius =
(int)round(searchRadiusSlider.value);
