iphone - How to get RGB color value from UISlider -

i have tried code not working properly.on value change of uislider called method...

@property (strong, nonatomic) iboutlet uislider *r; @property (strong, nonatomic) iboutlet uislider *g; @property (strong, nonatomic) iboutlet uislider *b; @property (strong, nonatomic) iboutlet uilabel *colorlabel;  - (void)viewdidload {     [super viewdidload];      _r.minimumvalue=0;     _r.maximumvalue=255;      _g.minimumvalue=0;     _g.maximumvalue=255;      _b.minimumvalue=0;     _b.maximumvalue=255;      // additional setup after loading view, typically nib. }  -(void)slidervaluechanged:(uislider*)slider {     [_colorlabel setbackgroundcolor:[uicolor colorwithred:_r.value green:_g.value blue:_b.value alpha:1]]; } 

please if 1 have idea..

use setting color method as

-(void)slidervaluechanged:(uislider*)slider {     float r=[[nsstring stringwithformat:@"%.0f",_r.value] floatvalue];     float g=[[nsstring stringwithformat:@"%.0f",_g.value]floatvalue];     float b=[[nsstring stringwithformat:@"%.0f",_b.value]floatvalue];      uicolor *colortoset=[uicolor colorwithred:(r/255.0f) green:(g/255.0f) blue:(b/255.0f) alpha:1];     [_colorlabel setbackgroundcolor:colortoset]; }
