IPHONE: check if there is a view in view mode

Question

I'm going to do

[vistaX removeFromSuperview];

How can I check if vistaX is present in a super view before removing it? Deleting a view that is not there will cause the application to crash ...

Thanks for any help.

Answer 1

You can protect it with:

if(vistaX.superview)
     [vistaX removeFromSuperview];

Although, I did not know that removeFromSuperview would fail if there was no supervisor. Are you sure this is a problem, and it may not be due to removeFromSuperview freeing up the view?
