如何獲取UIWebView中的所有請求？

Question

我想獲取UIWebView中的所有請求列表（圖像/視頻/ CSS）。 我使podclass NSURLCache，它的工作，但我碰到。

代碼：

#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]; 

    } 

崩潰：

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

我通過NSURLProtocol解決了這個問題（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; 
}

嘗試優化NSURLCache：
