Asynchronous NSURLConnection on separate thread fails to call delegate methods

阅读更多关于 Asynchronous NSURLConnection on separate thread fails to call delegate methods

问题 I am running a NSURLConnection on a separate thread (I am aware that it is asynchronous and works when running on the main thread), but it is not making delegate calls even when I pass the parent thread as the delegate. Does anyone know how to do this? Code: -(void)startConnectionWithUrlPath:(NSString*)URLpath { //initiates the download connection - setup NSURL *myURL = [[NSURL alloc] initWithString:URLpath]; myURLRequest = [NSMutableURLRequest requestWithURL:myURL cachePolicy

The problem is that the delegates connection:didReceiveData: method is never being called. Here's my code: @implementation Twitter -(id)init{ if (self=[super

This has a new delegate, NSURLConnectionDownloadDelegate with two key methods. connection:didWriteData:totalBytesWritten:expectedTotalBytes: is invoked repeatedly while the file download is progressing connectionDidFinishDownloading:destinationURL: is called once when the download is complete. The downloaded file should then be at destinationURL (at least for

how to unit test a NSURLConnection Delegate?

阅读更多关于 how to unit test a NSURLConnection Delegate?

问题 How can I unit test my NSURLConnection delegate? I made a ConnectionDelegate class which conforms to different protocols to serve data from the web to different ViewControllers. Before I get too far I want to start writing my unit tests. But I don't know how to test them as a unit without the internet connection. I would like also what I should do to treat the asynchronous callbacks. 回答1: This is similar to Jon's response, couldn't fit it into a comment, though. The first step is to make sure
