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];

Answer 1

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…
