Handling a NSURLRequest with timeout when using delegate

Question

I'm using a NSMutableURLRequest to connect to a web site to get a JSON response. I'm doing so by generating the request, and then using NSURLConnection with a delegate of self to handle the async connection. I've implemented all the normal delegate methods:

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
- (void)connectionDidFinishLoading:(NSURLConnection *)connection

All works perfectly with getting data back, dealing with any errors that occur, etc. However with the timeout on the NSURLRequest set to 10 seconds I don't seem to get called in those methods (I expected the didFailWithError to get called). It just sits there forever and I have no notification that it timed out.

Reading the iPhone API docs I don't see any mention of what should happen when the timeout occurs, just that you can set the timeout value. What should happen? I didn't see any other delegate methods in the API that would help. I don't have to manually check for timeouts, do I? Are timeouts only for synchronous requests?

Answer 1

Put some log in each method and check what they give? whenever time out definitely u getting a notification on console about time out . i m getting that notification . check your code once and still have problem let we know?

Answer 2

u will br receiving such type of iofo:

in did fail with error: Error Domain=NSURLErrorDomain Code=-1001 UserInfo=0xed4870 "timed out"

Answer 3

Your timeout is received in this method:

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error

Answer 4

The timeout behaviour is a bit quirky, see this thread on Apple’s developer forums.
