Default Checking if UIView has been removed?

I'm wondering if there is a method to check if a UIView has been removed from its superview or if it's still there. I'm using "removeFromSuperview" to remove the UIView, and even release it from memory.

Code:
[myView removeFromSuperview];
[myView release];
I know I can simply create a boolean that keeps track of it by setting it at the same time the view loads/unloads, but just thought this would be neater.

What I've tried so far is to check it's existence using this code:

Code:
if (myView) {}
But it always returns true even though myView has been removed.

If it's any help, the view has been created entirely by code and has no nib-file.

The way i do this is to loop through the .subviews NSArray and perform a check then see whether or not i need to remove and what exactly.

Well, in my case it turned out to be easier to just set it to nil instead of releasing it, and the conditional statement worked fine. Thanks for the input, though
