Hi, folks;
I've found the solution, and I thought I'd post it here in case it
ever happens to anyone else.
The function at the end, [self loadURLRequest], loads urlRequest in
the main frame of a WebView. It works as expected if the page has no
frames, but if it does have a frame, you need to retain the frame you
load the URL request in. Even though I was using [webView mainFrame],
it's de-allocating when frames exist.
Thanks for everyone's suggestions.

Hi, folks;
I've got a weird crash that's driving me crazy. Hopefully someone
out there can shed some light on the situation.
I have a method that navigates a WebView to a particular URL.
Sometimes, it posts data along with the request, sometimes not. The
POST data is sorted in an NSData called pendingData, and the
function looks something like this:
if (pendingData == nil) {
// Simple request
urlRequest = [NSURLRequest requestWithURL:url];
} else {
// POST request
urlRequest = [NSMutableURLRequest requestWithURL:url];
[urlRequest setHTTPMethod:@"POST"];
// Encode data
// (snipped)
}
[self loadURLRequest:urlRequest];
In the case where pendingData is nil, everything works perfectly.
In the case where it's not nil, I get an NSURLConnection. My POST
data encoding definitely works, because it has worked in the past
-- something else got broken. Just setting the HTTP method to
"POST" is enough to cause the crash.
Here's the crash log:

If anyone out there can help, I'd be really appreciative. Thank you
in advance;
