NSURLProtocol 用本地资源替换远程请求，video 在 smilulator 上可以播放，在 iPad , iPod touch 上不可以

[nkwhya]

NSURLProtocol 实现用本地资源替换远程请求，video在smilulator上可以播放，在ipad,itouch上不可以，报如下错误： 有大拿知道怎么解么，在simulator上会收到有range请求头的request ，在device上没有这个log...

试试重载uiurlcache
#import "HPURLCache.h"


@implementation HPURLCache

- (NSCachedURLResponse *)cachedResponseForRequest:(NSURLRequest *)request {

NSString *pathString = [[request URL] absoluteString];
NSLog(@"request %@",pathString);

if ([pathString hasSuffix:@"scriptstyle_1_post.css?i5D"]) {


NSData *css = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"scriptstyle_1_post" ofType:@"css"]];

NSURLResponse *response = [[NSURLResponse alloc] initWithURL:[request URL]
MIMEType:@"text/css"
expectedContentLength:[css length]
textEncodingName:nil];
return [[NSCachedURLResponse alloc] initWithResponse:response data:css];

}

return [super cachedResponseForRequest:request];
}

@wujichao 这个方法也试过了，video在simulator上都不好使，所以改成了nsurlprotocol.
你知道怎么用cfnetwork监听网络请求么

@nkwhya 不懂呢，我只试过替换js和css
