iOS网络请求 添加全局代理 NSURLSessionConfiguration 解决方案

由 拥有回忆 提交于 2020-01-13 18:10:11
1、最近做项目、文件存储服务器是用的亚马逊的、如果直接访问、下载其资源速度很慢、所以需要在网络请求的时候添加一个代理、加速网络访问 2、代理服务器是一个HTTPS 的一个服务器 3、思路、解决方案、利用运行时机制(添加分类NSURLSession+Change)针对 NSURLSession 初始化添加代理对所有的网络请求进行拦截处理 #import "NSURLSession+Change.h" @implementation NSURLSession (Change) +(void)load{ Method oldMethod = class_getClassMethod(self, @selector(sessionWithConfiguration:delegate:delegateQueue:)); Method newMethod = class_getClassMethod(self, @selector(newSessionWithConfiguration:delegate:NSURLSessiondelegateQueue:)); Method oldMethod1 = class_getClassMethod(self, @selector(sessionWithConfiguration:)); Method newMethod1 = class

Why does connecting back to an iOS background NSURLSession take too long waiting on a lock, crashing the app?

由 拟墨画扇 提交于 2020-01-12 18:51:48
问题 Why would connecting with an NSURLSession through its configuration take so long that it would crash the app on start up: 'failed to launch in time'? I've seen similar crash dumps in many iOS apps including NY Times iOS app and Evernote app. [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:queue] Here's the stack trace: Thread 0: 0 libsystem_kernel.dylib 0x3afb7aa0 semaphore_wait_trap + 8 1 libdispatch.dylib 0x3af04d3d _dispatch_semaphore_wait_slow + 173 2

iOS 7 background upload and POST requests

由 大城市里の小女人 提交于 2020-01-11 03:45:07
问题 I need to upload files in the background with other HTTP POST requests before and after each upload. Previously I was using beginBackgroundTaskWithExpirationHandler which was working perfectly till iOS 6 but from IOS 7 it is restricted for approx 180 seconds only which is a concern. I have read the documents regarding NSURLSession were in we have Background transfer service. But the problem with this is it only allows upload and download in background. It doesn't allow me to make POST request

NSURLSessionDataTask dataTaskWithURL completion handler not getting called

由 旧城冷巷雨未停 提交于 2020-01-09 05:17:30
问题 I have been learning Objective C lately, and I decided to try connections. Everything was great with NSURLConnection, until I discovered it was outdated, and tried to work with NSURLSession. I am trying a very simple example, but can't seem to get my app to run the code inside the completion block. Here is the code used: NSURL * url = [NSURL URLWithString:@"http://api.openweathermap.org/data/2.5/weather?q=London,uk"]; NSLog(@"2"); NSURLSessionConfiguration *defaultConfigObject =

NSURLSession resume from crash

由 情到浓时终转凉″ 提交于 2020-01-06 17:26:46
问题 Has anyone got any tips on how to reconnect to a download in a NSURLSession after a crash. If my app crashes, I believe the download continues on the device anyway, and then when my app relaunches I can use the same sessionID in: NSURLSessionConfiguration.backgroundSessionConfiguration(sessionID) However, am I then supposed to call 'session.getTasksWithCompletionHandler' to see if there are any tasks? The docs aren't clear. My UI has a download progress bar for each file download, so ideally

iOS: trigger NSURLErrorServerCertificateUntrusted instead of NSURLErrorCancelled when failing the AuthenticationChallenge

由 左心房为你撑大大i 提交于 2020-01-06 07:59:44
问题 I'm handling the server trust authentication challenge in a custom way (comparing the public key from the server trust with a hashed local version) through the urlSessionDelegate, similarly to how it is done here: How do I accept a self-signed SSL certificate using iOS 7's NSURLSession and its family of delegate methods for development purposes? As described in the documentation, I need to cancel the challenge if I want to fail the server trust authentication myself. When doing this, my data
