NSURLConnection, NSURLRequest, untrusted cert and user authentication

由 北慕城南 提交于 2019-12-09 03:06:40
问题 Morning Everyone, I've been attempting to write an application that does some GETs from a remote Web Service that requires authentication. My main problem is that the majority of these remote servers (and there are a lot of them) don't have valid certificates. I've got code to accept the invalid certificate and code to respond to the challenge with the correct uname & pass (below). The problem I'm having is getting the two to play together. I can't seem to find a way to send the challenge

lock screen interrupts NSURLConnection

由 空扰寡人 提交于 2019-12-08 23:56:32
问题 I'd like to know what's happening behind the scenes when the user locks and unlocks the iPad screen. I have an app that downloads files using NSURLConnection and the downloads fail with a SOAP error ("A server with the specified hostname could not be found"), but not when the user locks the screen, but when it unlocks it. Regardless of the fact when the error pops up, the download never finishes. Any ideas why and what could be done about it ? NSMutableURLRequest* request =

Reusing an instance of NSURLConnection

由 蓝咒 提交于 2019-12-08 19:51:26
问题 I'm using an instance of NSURLConnection on the iPhone to request data from a server, managed by a delegate as usual. The requests are quite frequent (maybe once every 2 minutes say) and have a common and fixed URL. Rather than seeing the good instance of NSURLConnection being released after each download and then a new one being created: Is there any worth in retaining the first connection and reusing it? (I'd hope so, one good authentication should be worth a thousand.) If so, how do I

Encoding UIImage to Base64 string not working when transferred to server

由 孤者浪人 提交于 2019-12-08 11:08:30
问题 Encoding an UIImage as a Base64 string works on the device, but transferring the string to the server somehow corrupts the string and prevents the server from successfully decoding the image. Any suggestions on the problem? // Define params params["thumbnail_base64"] = imageToBase64(blockSet.thumbnailURL) ... // Convert params -> query string let postString = buildQueryString(params) // Define upload URL let uploadURL = NSURL(string: RootURL + UploadFilePath)! // Hit server let request =
