如何在UIWebView中列出所有请求？

Question

我想在UIWebView中获取所有请求列表（image / video / css）。 我制作了podclass NSURLCache ，它正在运行，但是我崩溃了。

代码：

#import <Foundation/Foundation.h>

@interface CacheProxy : NSURLCache

@end

#import "CacheProxy.h"

@implementation CacheProxy

- (NSCachedURLResponse*)cachedResponseForRequest:(NSURLRequest*)request
{
    NSLog(@"url %@", request.URL);

    return [super cachedResponseForRequest:request];
}

@end

初始化：

  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        CacheProxy *cache = [[CacheProxy alloc] initWithMemoryCapacity:100 * 1024 * 1024
                                      diskCapacity:0
                                          diskPath:nil];
        [NSURLCache setSharedURLCache:cache];

    }

崩溃：

CFNetwork`__CFURLCache::SetMemoryLimit(long, long):

尝试优化NSURLCache：

我通过NSURLProtocol解决了这个问题（http://www.raywenderlich.com/59982/nsurlprotocol-tutorial - 很好的教程）

#import <Foundation/Foundation.h>

@interface MyURLProtocol : NSURLProtocol

@end


#import "MyURLProtocol.h"

@implementation MyURLProtocol

+ (BOOL)canInitWithRequest:(NSURLRequest *)request
{
    static NSUInteger requestCount = 0;
    NSLog(@"Request #%u: URL = %@", requestCount++, request.URL.absoluteString);
    return NO;
}
