Question

I have three UIButtons which display in a random order using:

NSMutableArray *indexArray = [NSMutableArray arrayWithObjects:
                              [NSValue valueWithCGRect:CGRectMake(20, 187, 280, 44)],
                              [NSValue valueWithCGRect:CGRectMake(20, 258, 280, 44)],
                              [NSValue valueWithCGRect:CGRectMake(20, 330, 280, 44)], nil];

//Randomize the array
NSUInteger count = [indexArray count];
for (NSUInteger i = 0; i < count; ++i) {
    int nElements = count - i;
    int n = (arc4random() % nElements) + i;
    [indexArray exchangeObjectAtIndex:i withObjectAtIndex:n];
}

//Assign the frames
button1.frame = [((NSValue *)[indexArray objectAtIndex:0]) CGRectValue];
button2.frame = [((NSValue *)[indexArray objectAtIndex:1]) CGRectValue];
button3.frame = [((NSValue *)[indexArray objectAtIndex:2]) CGRectValue];

For some reason I an unable to hide these buttons after they display a number of items. I have tried for example

button1.hidden = YES; and also
[self.button1.hidden = YES];

Any ideas? Any help would be most appreciated.

Answer 1

Pass tag to Buttons and use below code

 for (UIButton *btn in [self.view subviews]) 
    {
        if (btn.tag==1)
        {
            [btn removeFromSuperview];
        }
   }

and your problem will be resolved and revert me..
