Crash issue in viewForHeader in section method

Question

I am getting this crash issue when dragging the Control centre while using my app. Crash message is [ViewController tableView:viewForHeaderInSection:]: message sent to deallocated instance 0x17dbb9a0

Code is:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    if(section == self.groupsArray.count)
    {            
        customView = [[UIView alloc] initWithFrame:CGRectMake(10.0, 0.0, 300.0, 24.0)];
        [customView setBackgroundColor:[UIColor clearColor]];

        return customView;
    }

    return nil;
}

I am using Xcode 6 and enabled ARC . Could any one please help me to resolve this issue.

I have tried to take the help of Properties but doesn't work. Thank you for reading my post.

Which line does this error occur on? Have you used an exception breakpoint? — ZeMoon, Oct 29 '14 at 09:31
The problem is your ViewController instance. That's the object that gets deallocated. That this method is involved is just a symptom. You should show how you create and present that ViewController — Matthias Bauch, Oct 29 '14 at 09:32
Hey @ZeMoon I have used breakpoint but doesn't show the error in the viewForHeaderInSection method — Tendulkar, Oct 29 '14 at 09:43
hey @MatthiasBauch I think the issue is not with the view controller . If I comment the viewForHeaderInSection method I am not getting any crashes. — Tendulkar, Oct 29 '14 at 09:44
Are you explicitly calling the method someplace in your code? — ZeMoon, Oct 29 '14 at 09:51

@Bala I know which method is causing for the crash issue but couldn't solve the issue — Tendulkar, Oct 29 '14 at 10:25

delegate of your tableview is deallocated whenever viewForHeaderInSection is called. make sure your viewcontroller is the delegate and check when and where it is getting deallocated.
