RemoveFromSuperView不起作用

Question

Although I declared the UIView in the header file (as below):

IBOutlet UIView *aCustomMsgBoxView;

The RemoveSuperView works in one method but not in the other. It works if I put it in this method:

-(IBAction)showMsgBox:(id)sender

{

vc = [ViewController sharedInstance].self;

aCustomMsgBoxView = [[UIView alloc] init];

NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"customMsgBox" owner:self options:nil];

aCustomMsgBoxView = [nibObjects objectAtIndex:0];

aCustomMsgBoxView.frame = CGRectMake(35, 80, 250, 146);

[vc.view addSubview:aCustomMsgBoxView];
}

But I don't need it in the above method, I need it in the method below where it doesn't work:

-(IBAction)hideMsgBox:(id)sender

{

    [newAnnotationTitle resignFirstResponder];

    [aCustomMsgBoxView removeFromSuperview];
}

Of course both methods sit in the same class...

Why isn't the view being removed from the screen??

Answer 1

Following code may be help for remove UIView (aCustomMsgBoxView)

  -(IBAction)hideMsgBox:(id)sender

{
    [newAnnotationTitle resignFirstResponder];

    [UIView animateWithDuration:0.25
     animations:^{ self.aCustomMsgBoxView.alpha = 0.0;}
     completion:^(BOOL finished){ [ self.aCustomMsgBoxView removeFromSuperview]; }];

}

Thanks :)
