AFCacheableItemInfo returning MIME type of 'plain/text' after first use

[tonyarnold]

I've got an odd problem where I'm getting a MIME type of 'plain/text' on items that were previously 'image/jpeg' or 'video/mp4'. It seems to happen only after I've quit and restarted my app, or after I've recalled the item from cache already. Here's how I'm retrieving items from cache:

Am I doing something wrong?

I have a similar problem.
I've made a modification in AFURLCache that seems to fix the problem : I have to split the content-type and the charset :

-(NSCachedURLResponse_)cachedResponseForRequest:(NSURLRequest_)request
{
NSURL* url = request.URL;
AFCacheableItem* item = [[AFCache sharedInstance] cacheableItemFromCacheStore:url];
if (item && item.cacheStatus == kCacheStatusFresh && item.data) {
NSRange oRange = [item.info.mimeType rangeOfString:@"charset="];
NSString* oMimeType = item.info.mimeType;
NSString* oCharset = nil;
if (oRange.location != NSNotFound)
{
oMimeType = [[[item.info.mimeType substringToIndex:oRange.location] stringByReplacingOccurrencesOfString:@";" withString:@""]
stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
oCharset = [[item.info.mimeType substringFromIndex:(oRange.location + oRange.length)] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
}
NSURLResponse* response = [[NSURLResponse alloc] initWithURL:item.url
MIMEType:oMimeType
expectedContentLength:[item.data length] textEncodingName:oCharset];
NSCachedURLResponse *cachedResponse = [[NSCachedURLResponse alloc] initWithResponse:response data:item.data userInfo:nil storagePolicy:NSURLCacheStorageAllowedInMemoryOnly];
[response release];
NSLog(@"Cache HIT for file: %@", [[AFCache sharedInstance] filenameForURL: url]);
return [cachedResponse autorelease];
} else {
NSLog(@"Cache miss for file: %@", [[AFCache sharedInstance] filenameForURL: url]);
}

NSCachedURLResponse *response = [super cachedResponseForRequest:request];
return response;

}

Also I added a test on item.data because sometimes I got nil which ends with a blank page in UIWebView.
