It's not the efficient way to set a UIView hidden. You can Add SubView & RemoveFromSuperView is the optimum way.

Add it to your Super View

[self.mkMapView addSubview:self.mapTypeVIew];

To remove it from SuperView

[self.mapTypeVIew removeFromSuperview];

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event  {
   NSLog(@"touches began");
   UITouch *touch = [touches anyObject];
   if(![touch.view isKindOfClass:[self.mapTypeVIew class]])
   {
      self.mapTypeVIew.hidden = YES;
      self.mapTypeVIew.alpha = 0.0;
   }
}

and while showing ,

-(IBAction)mapButtonPressed:(id)sender
 {
    self.mapTypeVIew.hidden = NO;
    self.mapTypeVIew.alpha = 1.0;
 }
