nsurlconnection

I'm trying to run NSURLConnection async in a secondary thread (target is iOS4), for this I have created a concurrent NSOperation, I think I'm almost there, but am not clear on the following: 1) in iOS4 NSOperationQueue addOperation starts the operation in a new thread, because of the use of GCD, based on Technical Q&A QA1712 , however, my tests (simulator and iPad) show that start() is always called on the main thread, any idea, do I need a check here: if on main thread then spawn a new one? 2) if start was actually called on a secondary thread by addOperation(), then I could start my async

I'm a little new to objective-C but have run across a problem that I can't solve, mostly because I'm not sure I am implementing the solution correctly. I am trying to connect using a Synchronous Connection to a https site with a self-signed certificate. I am getting the Error Domain=NSURLErrorDomain Code=-1202 "untrusted server certificate" Error that I have seen some solutions to on this forum. The solution i found was to add: - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { return [protectionSpace

I am trying to create an xls sheet programmatically. To fill the sheet, I am making the multiple NSURLConnection around 100. Right now, my approach is : Make a connection and store the data into an array . This array has 100 objects. Now take the first object and call the connection . Store the data. And make the second connection with 2nd object in the array. This continues till the last object in the array. It takes on average 14 seconds to finish the 100 connections. Is there any way to implement the NSURLConnection to get the response in a faster way? Till yesterday I followed the basic

I have a connection in a thread, so I add it to the run loop to get all data: [[NSRunLoop currentRunLoop] run]; [connection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; But I can't find any way to stop it - (void)connectionDidFinishLoading:(NSURLConnection *)connection{ if([NSRunLoop currentRunLoop]){ [[NSRunLoop currentRunLoop] cancelPerformSelectorsWithTarget:self]; } [connection cancel]; } How can I stop this loop? You can stop the runloop by Core Fundation API : CFRunLoopStop(CFRunLoopGetCurrent()); 来源： https://stackoverflow.com/questions/16211915/stop-an

I'm running in to an issue in an OS X app that creates multiple, persistent connections to the same host using NSURLConnection. I create a separate connection for different rooms, and it stays connected the entire time the room is open to consume a streaming API. When opening many rooms, it stops working correctly. I created a separate sample app that creates 10 connections, and it seems to only allow 6 connections to work, and the others are queued. Does anyone know if there is a way to override this limit? I can't find it documented anywhere. The only workaround I've found is it seems to be
