由 蓝咒 提交于 2019-12-07 07:44:25
I am experiencing a disturbing issue when trying to execute one of my apps on an iPhone 4S with iOS8 and Xcode 6.0.1.

由 岁酱吖の 提交于 2019-12-07 05:31:35
问题 Coming from the world of web programming, I'm pretty much comfortable with working with multipart form requests to upload files.

Always getting back cached data in NSURLSessionDataTask

由 放肆的年华 提交于 2019-12-07 04:24:52
问题 I'm facing a very strange issue when using NSURLSessionDataTask to post a JSON request to the server. The first request goes through and I receive the correct JSON response, when I do a second request I'm getting always back the old response and the server never receives the request. Even if I turn on airplane mode the NSURLSessionDataTask does work an I get back the old response again. That's the code I'm using: - (void)getJSONFromURL:(NSURL*)url identifierCode:(NSInteger)code {

问题 Can anyone help me in understanding these question : What is the advantage of using Alamofire over NSURLSession/ NSURLConnection?
