How to Insert View in Superview's View? (iOS)

Question

I have the line of code below... How would I modify it to insert the subview in the superview's view named 'foo'?

[[self superview] addSubview:copy3];

If you are using storyboard, and superview and your view are in the same view controller's view, you can just define an outlet and refer to it? — nhahtdh, Jun 08 '12 at 03:28
What do you mean by "named foo"? Views don't have a name property, do you have an ivar named foo? — rdelmar, Jun 08 '12 at 03:42
I'm thinking the code would look something like this" [[self superview].foo addSubview:copy3]; — William LeGate, Jun 08 '12 at 04:18
Bad approach. Let view controller or at least superview manage where to insert your view. — Roman Temchenko, Jun 08 '12 at 17:10

There are more than 1 ways of doing this -

1.have an IBOutlet reference in your code. This is created from xcode Interface builder. Once you have this then it fairly straight forward -

[iboutlet_foo_object addSubview:copy3];

2.tag the view that you are interested in. Again tagging a view can be done from xcode Interface builder or from code. After that -

Foo *fooObj = [[self superview] viewWithTag:tagInt];
[fooObj addSubview:copy3];

3.Finally you can iterate through all the views in your superview & see which one is of type Foo -

NSArray *subviews = [[self superview] subviews];
for(UIView *v in subviews)
{
    if(v isKindOfClass:[Foo class])
    {
        [v addSubview:copy3];
        break;
    }
}

hope these methods help you...

Hmm... It's not recognizing the view in the other view controller using your methods. – William LeGate Jun 08 '12 at 05:49
you need to have a reference to it in your new viewController. First create an empty instance of `foo` class. Then try to copy reference of `foo` from your oldViewController to your newViewController. – Srikar Appalaraju Jun 08 '12 at 07:13
foo isn't a class... It's a uiview declared in the parent view – William LeGate Jun 08 '12 at 16:28

First make myView into a property of the superview Then use

[[[self superview] myView] addSubview:mySubview];

It says instance method not found... Any idea why? EDIT: it looks like the other guy's answer is working. – William LeGate Jun 08 '12 at 18:28
ok :), you should have made myView int an @property in the view super view class – Omar Abdelhafith Jun 08 '12 at 18:35
I had added myView as an @property. What do you mean myView int? – William LeGate Jun 08 '12 at 20:05
sorry a type, did you @ synthesize it? – Omar Abdelhafith Jun 08 '12 at 20:10

First tag the view myView with a unique number:

myView.tag = 0x1234;

Then you can find it using viewWithTag:

[[[self superview] viewWithTag:0x1234] addSubview:mySubview];

Okay, so it no longer ads the subview to the view it was... but its not adding it at all now. Probably because it cant find a view with the tag I set even though I set the tag in the superview. Any idea why its not finding it? – William LeGate Jun 08 '12 at 18:31

You might just actually add it to 'view' instead of 'superview'.

[[self view] addSubview:mySubview];

It works just fine for me, whenever I add subviews to my parent view. Let me know if something went wrong.
