NSURLCache不会清除iOS8中存储的响应-NSURLCachedoesnotclearstoredresponsesiniOS8

Here is the sample function i call when i need to clear cache and make a new call to URL

这是我需要清除缓存并对URL进行新调用时调用的示例函数

- (void)clearDataFromNSURLCache:(NSString *)urlString
{
    NSURL *requestUrl = [NSURL URLWithString:urlString];
    NSURLRequest *dataUrlRequest = [NSURLRequest requestWithURL: requestUrl];

    NSURLCache * cache =[NSURLCache sharedURLCache];


    NSCachedURLResponse* cacheRespOnse=[cache cachedResponseForRequest:dataUrlRequest];

    if (cacheResponse) {
        NSString* dataStr = [NSString stringWithUTF8String:[[cacheResponse data] bytes]];
        NSLog(@"data str r= %@",dataStr);
        NSLog(@"url  str r= %@",[[[cacheResponse response] URL] absoluteString]);
        [cache storeCachedResponse:nil forRequest:dataUrlRequest];
        [NSURLCache setSharedURLCache:cache];
    }

    [[NSURLCache sharedURLCache] removeCachedResponseForRequest:dataUrlRequest];

    //Check if the respnase data has been removed/deleted from cache
    NSURLRequest *finalRequestUrlRequest = [NSURLRequest requestWithURL:requestUrl];
    NSURLCache * finalCache =[NSURLCache sharedURLCache];

    NSCachedURLResponse* finalcacheRespOnse=[finalCache cachedResponseForRequest:finalRequestUrlRequest];

    if (finalcacheResponse) {
        //Should not enter here
        NSString* finaldataStr = [NSString stringWithUTF8String:[[finalcacheResponse data] bytes]];
        NSLog(@"data str r= %@",finaldataStr);
        NSLog(@"url  str r= %@",[[[cacheResponse response] URL] absoluteString]);
    }
}

In iOS 6/7 the response is deleted successfully for the requestURL, but in iOS 8 it never gets deleted. I have searched but could not find reason why this should not work in iOS8.

在iOS 6/7中，requestURL的响应被成功删除，但在iOS 8中它永远不会被删除。我已搜索但无法找到原因，这在iOS8中不起作用。

Any help will be appreciated…..

任何帮助将不胜感激…..
