Question

Please read my question before marking it as duplicate or repeat question…

1. I have one scroleView in which I put some images in tabular form.

2. When user click one of it the next view controller is shown and the
   clicked image’s uiview get green border.

3. And when user navigate back to this view the clicked image is shown
   with green border. all this worked fine

But the problem starts when user clicks other images : the previously clicked image doesn’t get back to normal, ie, its border stays there even if I put its width to 0.0 and color to clearColor

Please guide me how to remove those borders

My code is as below:

for (int row = 0; row < r; ++row)
    {
        for (int col = 0; col < 2; ++col)
        {
            int index = (row * 2) + col;
            if(index < [tempArr count])
            {
                CGRect frame = CGRectMake(10+col*(10+145),10+row*(5+100),145, 100);
                UIView *fr = [[UIView alloc] initWithFrame:frame];
                CGRect imgFrame = CGRectMake(0, 0, 145, 100);
                UIImageView *imgView = [[UIImageView alloc]initWithFrame:imgFrame];
                imgView.image = [UIImage imageNamed:[[tempArr objectAtIndex:index]valueForKey:@"add"]];
                UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapAction:)];
                fr.layer.borderWidth = 0.0f;
                fr.layer.borderColor = [UIColor greenColor].CGColor;
                if(selctedFrame == index)//Here i put border
                {
                    fr.layer.borderWidth = 2.0f;
                    fr.layer.borderColor = [UIColor greenColor].CGColor;
                }
                else //here i remove them
                {
                    fr.layer.borderWidth = 0.0f;
                    fr.layer.borderColor = [UIColor clearColor].CGColor;
                }
                tapGesture.numberOfTapsRequired = 1;
                tapGesture.numberOfTouchesRequired = 1;
                [fr addGestureRecognizer:tapGesture]; 
                [fr addSubview:imgView];
                fr.tag = index;
                [self.scrollDisplay addSubview:fr];
                [self.scrollDisplay bringSubviewToFront:fr];
            }
        }
    }
    [self.view addSubview:self.scrollDisplay];

This method is called in viewWillAppear:animated: method

Edit

after some navigation forth and back
