ASIHTTP(http://allseeing-i.com/ASIHTTPRequest/How-to-use#using_a_download_cache)を使用してデータをキャッシュに保存しようとしています。何が間違っているのかわかりませんが、データをキャッシュに保存していないようです。次のコードの出力は次のとおりです。
2010-08-12 15:44:13.801 TabBar[51728:207] Success is YES
2010-08-12 15:44:13.802 TabBar[51728:207] Success is NO
2010-08-12 15:44:13.804 TabBar[51728:207] Success is YES
2010-08-12 15:44:13.805 TabBar[51728:207] S-----------
2010-08-12 15:44:13.874 TabBar[51728:207] Success is YES
2010-08-12 15:44:13.874 TabBar[51728:207] Success is NO
2010-08-12 15:44:13.876 TabBar[51728:207] Success is YES
コードは次のとおりです。
[[ASIDownloadCache sharedCache] clearCachedResponsesForStoragePolicy:
ASICacheForSessionDurationCacheStoragePolicy];
[[ASIDownloadCache sharedCache]
setDefaultCachePolicy:ASIOnlyLoadIfNotCachedCachePolicy];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL
URLWithString:@"http://www.nytimes.com/"]];
[request setDownloadCache:[ASIDownloadCache sharedCache]];
[request startSynchronous];
request = [ASIHTTPRequest requestWithURL:[NSURL
URLWithString:@"http://www.nytimes.com/"]];
[request setDownloadCache:[ASIDownloadCache sharedCache]];
[request startSynchronous];
BOOL success = ([request responseStatusCode] == 200);
NSLog(@"Success is %@\n", (success ? @"YES" : @"NO"));
success = [request didUseCachedResponse];
NSLog(@"Success is %@\n", (success ? @"YES" : @"NO"));
success = ([[request responseData] length]);
NSLog(@"Success is %@\n", (success ? @"YES" : @"NO"));
NSLog(@"S-----------");
request = [ASIHTTPRequest requestWithURL:[NSURL
URLWithString:@"http://www.nytimes.com/"]];
[request setDownloadCache:[ASIDownloadCache sharedCache]];
[request startSynchronous];
success = ([request responseStatusCode] == 200);
NSLog(@"Success is %@\n", (success ? @"YES" : @"NO"));
success = [request didUseCachedResponse];
NSLog(@"Success is %@\n", (success ? @"YES" : @"NO"));
success = ([[request responseData] length]);
NSLog(@"Success is %@\n", (success ? @"YES" : @"NO"));
誰かがこれを達成する方法についてのコードスニペットを教えてもらえますか?
ありがとう!

新しいコードの改訂:
NSURL *url = [NSURL URLWithString:imageURL];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadCache:[ASIDownloadCache sharedCache]];
[request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy];
[request setCachePolicy:ASIOnlyLoadIfNotCachedCachePolicy];
[request setSecondsToCache:60*60*24*30]; // Cache for 30 days
[request startSynchronous];//startAsynchronous];
BOOL success = [request didUseCachedResponse];
NSLog(@"------------>>>>>>> Success is %@\n", (success ? @"YES" : @"NO"));
NSData *responseData = [request responseData];
UIImage *image = [[UIImage alloc] initWithData:responseData];
これは[requeststartSynchronous]でのみ機能します。非同期メソッドを試してみると、この関数は呼び出されません。
- (void)requestFinished:(ASIHTTPRequest *)request
