local declaration of 'myViewController' hides instance veriable

Question

In the action sheet delegate method im modaling to another view based on the button index, this is the method:

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {

    if (buttonIndex == 0) {
        NSLog(@"first button was pressed");
    } else if (buttonIndex == 1) {
        MyViewController *myViewController = [[MyViewController alloc]initWithNibName:@"MyViewController" bundle:nil];
        UINavigationController *navigationController = [[UINavigationController alloc]initWithRootViewController:myViewController];
        [self.navigationController presentViewController:navigationController animated:YES completion:nil];
    }
}

im getting the error next to the nevigationConroller declaration, does someone knows what is the problem?

im declaring MyViewController in the .h class of this class..

thanks

The class that contains your actionSheet:clickedButtonAtIndex: method has an ivar named myViewController. You have created a local variable also named myViewController. Your Xcode project has been told to treat this as an error instead of just a warning. Change your local variable name.

MyViewController *myVC = [[MyViewController alloc]initWithNibName:@"MyViewController" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc]initWithRootViewController:myVC];
[self.navigationController presentViewController:navigationController animated:YES completion:nil];
