Displaying the subview with first tap on button at the second am removing subview.Its working fine, but am getting a warning is ***switch condition has boolean value*** 

```
Bool Selected;

-(void)ageview
{
    switch (Selected) {
        case 0:
            ageview=[[UIView alloc]initWithFrame:CGRectMake(26, 110, 100, 135)];
            ageview.backgroundColor=[UIColor whiteColor];
            [self.view addSubview:ageview];

            Selected=1;
            break;
        case 1:
            [ageview setHidden:YES];
            Selected=0;
            break;

        default:
            break;
    } 
}

```
