Question

What is the correct way to clear a UIWebView delegate ?

In my dealloc function, I added

[myWebView setDelegate:nil];
[myWebView release];

And is the first ligne necessary ?

EDIT : and what if my object was not a UIWebView but a NSFetchedResultsController ?

Thanks

Setting the delegate to nil is one thing. Other, quite as important or even more, is how to cleanly shut down a loading UIWebView in a case when you don’t care about the result anymore and you’re about to release a view containing your UIWebView.

Here is a really good answer to above questions and more: How to safely shut down a loading UIWebView in viewWillDisappear?. It’ll give a good overview on UIWebView’s life-cycle.

A hint on calling stopLoading: you don’t have to check if anything is being loaded with isLoading before calling stopLoading – just call stopLoading directly and it will do nothing if nothing is being loaded.
