可以挂钩+ [NSURLSession sessionWithConfiguration:delegate:delegateQueue:]，但调用％orig会给出“无法识别的选择器"， [英] Can hook +[NSURLSession sessionWithConfiguration:delegate:delegateQueue:] but calling %orig gives "unrecognized selector"

问题描述

这让我感到困惑.我已经在NSURLConnection上钩上了类方法，没有问题，但是我陷在+[NSURLSession sessionWithConfiguration:delegate:delegateQueue:]上.

This is baffling me. I have hooked class methods on NSURLConnection with no problems but I am stuck with +[NSURLSession sessionWithConfiguration:delegate:delegateQueue:].

我什至尝试使用class_copyMethodList (object_getClass([NSURLSession class]), &count);记录所有类方法，而该类方法实际上在那儿: sessionWithConfiguration:delegate:delegateQueue: initialize

I even tried logging all the class methods with class_copyMethodList (object_getClass([NSURLSession class]), &count); and the class method is actually there: sessionWithConfiguration:delegate:delegateQueue: initialize

奇怪的是，钩子确实被调用了，所以我认为我们做对了.调用%orig()并仅将参数向下传递即可:

And the weird thing is the hook does get called so I think we got it right. Calling %orig() and just passing the parameters down yields:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSURLSession sessionWithConfiguration:delegate:delegateQueue:]: unrecognized selector sent to class 0x1919932b8'

这是钩子:

+ (NSURLSession *)sessionWithConfiguration:(NSURLSessionConfiguration *)configuration
                                  delegate:(id<NSURLSessionDelegate>)delegate
                             delegateQueue:(NSOperationQueue *)queue
{

    NSURLSession *origResult = %orig(configuration, delegate, queue);

    return origResult;
}

我想念什么吗?

推荐答案

此处的问题与

The problem here is related to NSURLSession being a class cluster. While the code in OP successfully hooked the class method, %orig needs to call on the real class name. So to make it work, this hook has to be placed under %hook __NSCFURLSession. The real class name might be different for your case.
