Try not putting WebViewProgressFinishedNotification in a string.
It's a named constant and not necessarily the same as the string
contained by that constant.

Hmm, I registered for WebViewProgressFinishedNotification, but I'm
not getting it. I also tried WebViewProgressStartedNotification and
WebViewProgressEstimateChangedNotification, and it's not picking
any of them up. Here's my code:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(WebViewProgressFinished:)
name:@"WebViewProgressFinishedNotification"
object:nil];
Is there something else I have to do?

I have a WebView, and I need to know when it's done loading. But
it has to do different things when it finishes loading, depending
on the method that invoked it, so I'm using the estimatedProgress
method instead of webView:didFinishLoadForFrame:. But for some
reason, it never gets to 1.0, even though the webView finished
loading. Is there something I'm missing?
1) Polling is bad.
2) Don't fight the frameworks. Use the methods intended to be used
for a specific task.
If you want to spread information about a finished download to
different areas, either send more than one method in the delegate
or send a notification from there. Any party interested in the
notification can subscribe for that notification. Many delegates
have a notification counterpart already.
