My code used a set of delegate methods (

问题 I'm using NSURLSession to perform an HTTP Post NSMutableURLRequest , using the dataTaskWithRequest:completionHandler: method. When I perform a request for the first time, things take a reasonable amount of time to complete and show some feedback in the completion handler. On the next time that same request is fired, it happens almost instantaneously with very little time in between, which leads me to believe that the system is caching the contents of this data task. As I don't need to view

问题 I'm working on a music app, which use ASIHTTPRequest to access to server's api, and use NSURLConnection to download music files. One music file is 10M or so. When downloading music file, access to server's api will be much more slow than not downloading music file. So I want to change download connection's priority lower. But there is no API to change priority of NSURLConnection or NSURLRequest . How to archive this? 回答1: I think only NSOperationQueues can be priorized. Here is a link to an

问题 I have an mp3 file on a server. I want to get this file's information like what's the size of this file, what's the artists name, what's the album name, when was the file created, when was it modified, etc. I want all this information. Is it possible to get this information without actually downloading the whole file? Using NSURLConnection or otherwise? EDIT: The following code doesn't give me the required information, i.e. file created by, artist name, etc NSError *rerror = nil;
