AFNetworking progress

由 此生再无相见时 提交于 2019-12-22 09:41:43
问题 I am trying to use setDownloadProgressBlock of AFHTTPRequestOperation class. The call back gives me 3 parameters: ( NSInteger bytesRead , NSInteger totalBytesRead , NSInteger totalBytesExpectedToRead ) In order for me to get the progress, I need the totalBytesExpectedToRead value, but it's giving me a -1. I checked the headers of the HTTP response and the content length is there... { "Cache-Control" = "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"; Connection = "Keep-Alive";

How do I make my AFNetworking “responseObject” that I receive a NSDictionary I can parse?

由 不羁的心 提交于 2019-12-22 09:28:24
问题 I have this call with AFNetworking 1.0 that returns a responseObject with the data from the API that I want: [[AFDiffbotClient sharedClient] postPath:@"http://diffbot.com/api/batch" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) { However, I have no idea how to process responseObject . If I check [responseObject class] I get NSData . If I NSLog(@"%@", responseObject) I get a bunch of numbers (memory addresses I assume): <5b0a7b22 68656164 65727322

correct way to embed base64 in json payload with afnetworking

由 筅森魡賤 提交于 2019-12-22 08:44:30
问题 thanks in advance for any help. I am working with a web service that only takes json payloads and this service is setup for submitting photos. So I am trying to figure out the proper way to embed an image in a json payload. This is my approach. //convert image to nsdata NSData *originalPhoto = UIImageJPEGRepresentation(self.photo.image,.9); //convert the data to a base64 string using NSData+Base64 category extension (Matt Gallagher version) NSString *base64photoString = [originalPhoto

AFNetworking: Access to completion handlers when retrying operation

问题 To give some context: I'm trying to implement a global error handler for authentication errors (using token authentication, not basic), which should try to re-authenticate and then repeat the original failed request (see my previous question: AFNetworking: Handle error globally and repeat request) The current approach is to register an observer for the AFNetworkingOperationDidFinishNotification which does the re-authentication and (if auth succeeded) repeats the original request: - (void

iOS 网络编程：AFNetworking

由 北城以北 提交于 2019-12-21 08:38:58
1 简介 1.1 概念 AFNetworking 网络框架并不是IOS自带的框架 ，而是第三方的开源框架。它是对NSURLConnection和NSURLSession API的封装，但是目前AFNetworking 3.0已经删除了基于 NSURLConnection API的所有支持，所以本文只记录基于NSURLSession API的相关接口。AFNetworking 框架是基于Object-C语言，若需要使用Swift语言版可以了解 Alamofire 框架。 个人感觉学习AFNetworking 框架非常麻烦，它没有提供guide，所以只能按着GitHub和头文件进行学习。 1.2 第一个程序 1.2.1 环境配置 环境配置非常简单，有多种方式，在GitHub提供了几种方法，这里使用最简单的方式：导入源码。 新建IOS项目后，导入在GitHub网站下载的AFNetworking 源码，如图 2所示。 图 2 1.2.2 源码 其使用如下所示，只需引入AFNetworking.h文件即可使用其API。 1 #include " AFNetworking.h " 2 -( void )DownloadTask 3 { 4 NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration
