Question

I have question regarding about finding subview using ‘.tags’ in one UIView.

for (UIView *viewObj in [self.view subviews])
{
   // want to find viewObject by its tag.
   // but I heard for-switch or for-case paradigm are bad pattern design by WTF.
   // there are total 9 of tags will be use for finding view object
   switch (viewObj.tag)
   {
         case 0:
         .
         ..
         ...
   }
}

How can I make this to be non-switch or non-if statement? Should I just add into one array then fetch from there? For example, you add views with desired tags and fetch from this array.

Thank you.

If it is only going to be a fixed number of views and each view has different methods that need to be performed you could access the views directly.

UIView* someView = [self.view viewWithTag:0];
//Operations on view 0


UIView* someOtherView = [self.view viewWithTag:1];
//Operations on view 1
