How to use NSURLConnection completionHandler with swift
block, nsurlconnection, swift
Solution
Like this:
NSURLConnection.sendAsynchronousRequest(request, queue: queue, completionHandler:{ response, data, error in /* Your code */ })
Or more verbose variant.
NSURLConnection.sendAsynchronousRequest(request, queue: queue, completionHandler:{ (response: NSURLResponse!, data: NSData!, error: NSError!) -> Void in
/* Your code */
})
Problem
Does anybody know how handlers (blocks) work in swift? I am trying to get this code running but i can't find any documentation of the right syntax for the completionHandler. ``` let url:NSURL = NSURL(string:"some url") let request:NSURLRequest = NSURLRequest(URL:url) let queue:NSOperationQueue = NSOperationQueue() NSURLConnection.sendAsynchronousRequest(request:request, queue:queue, completionHandler handler:((NSURLResponse!, NSData!, NSError!) -> Void)!) ```
