self.lbl=[[UILabel alloc] initWithFrame:CGRectMake(135, 290,200,35)];
    self.lbl.backgroundColor=[UIColor clearColor];
    NSString *str=[NSString stringWithFormat:@"%.f",[self.slider value]];
    [self.lbl setFont:[UIFont fontWithName:@"Arial-BoldMT" size:16]];
    self.lbl.text=str;
    [self.View addSubview:self.lbl];
