Hi, I've got a UITableView that loads an image asynchronously and places it in the UITableViewCell once it's loaded (I'm using almost the exact same code as in the "LazyTableImages" tutorial). This works fine for all images when I scroll the table, but it's not loading the images that are first in the view. The code is definitely worki...

When I run my NSURLRequest in Cocoa, I get a 303 HTTP error, which is a redirect. How can I pull the proper URL to redirect to? Is it in the error variable, or somewhere else? ...
Hi there, I've got a problem which I thought is pretty simple to fix but somehow I can't figure out what to do. I've got an URL like http://www.myserver.com/myservice.php?param=foobar. When I type that into Safari's address bar I see an result like "Error" or "OK". So, how do I properly call that URL from within my code and get that re...
I track user activity in my iPhone app by having certain user actions call an almost empty Web page that the app does nothing with. Rather, attached to the URL are some querystring paramaters that tell me who's doing something and what it is (after I analyze the logs, that is). I don't want launching the URL to slow down the app, so I p...

I'm having some problems with the iPhone simulator that don't seem to be occurring on the device. I have made a web service reference class with a bunch of static methods so different calls to a web service can be made from all over the application. The methods themselves contain a lock so only one request will be performed at a time. ...
Any way to get the size of a (remote, http) file without actually downloading it? All other similar questions seem to revolve around grabbing the expectedContentLength from the NSURLResponse object in didReceiveResponse: but I don't want to download the file, I just want to know how big it is. ...
I'm writing a class that uses a JSON API for a website I visit. In my class I use NSURLRequest to fetch the data, but then I need to give the data to the app delegate. I realize NSURLRequest is asynchronous so I can't directly return the data. So let's say in my class, the delegate calls getUserProfile, the method uses NSURLRequest to g...
I have a connection request working using the stringWithContentsOfURL:encoding:error: method from NSString. I want to be able to retry the connection if it fails the first time. I was going to rewrite the function to use the timeout functionality of NSURLRequest, but I think I'd really like to use multiple retries before failing out. As...
Whenever I set a body on a mutable request with the method set to anything other than POST, the body is not included in the request and I get a kCFErrorDomainCFNetwork error 303 (kCFErrorHTTPParseFailure) when the server replies. Changing the method to POST is all it takes for the request to go through with no error. Is there any way to ...
I am working on an image heavy iPad app. We implemented our own table view-esque control which reuses UIImageViews as a user scrolls the screen. To reduce network calls and make it perform better, I implemented a file backed UIImageView that writes the loaded images to the NSTemporaryDirectory and checks that before making a call to get ...
Hi I am building an iPhone app the retrieves a file from an IIS7 server. I'm using a plain old NSURLRequest to retrieve this file. The request works fine if I use another web server, but for some reason this one keeps giving me a 400 bad request. So I took a look at the request the NSURLRequest sends, and it looks like this: ::1 [Wed S...
