Hi,
I want to cache local files (images) so I cache a NSData using
[NSURLCache storeCachedResponse]
If I try to fetch it, the cachedResponseForRequest:request is always
nil under 10.5
This works under 10.4.
I tried to create my own sharedURLCache, but it still doesn't work.
I use
NSString *path = [NSString stringWithString:@"/Library/Desktop
Pictures/Nature/Clown Fish.jpg"];
NSImage* diskImage;
diskImage = [[NSImage alloc] initWithContentsOfFile:path];
NSData *data = [diskImage TIFFRepresentation];
NSURL *cacheURL = [NSURL fileURLWithPath:aPath];
NSURLResponse *response = [[[NSURLResponse alloc]
initWithURL:cacheURL
MIMEType:@"application/octet-stream"
expectedContentLength:[data length]
textEncodingName:nil] autorelease];
NSCachedURLResponse *cachedResponse = [[[NSCachedURLResponse alloc]
initWithResponse:response
data:data
userInfo:[NSDictionary
dictionary]
storagePolicy:NSURLCacheStorageAllowed] autorelease];
NSURLRequest *request = [NSURLRequest requestWithURL:cacheURL];
[self storeCachedResponse:cachedResponse forRequest:request];
cachedResponse = [self cachedResponseForRequest:request];
if (cachedResponse) {
NSLog(@"cached data for %@ is %d", [[cachedResponse response]
URL], [[cachedResponse data] length]);
} else {
NSLog(@"Cached response is NULL");
}
What is the correct way to use NSURLCache with NSData on 10.5?
I have a test project available <http://coriolis.ch/dl/cache.zip> if
anyone wants to have a look,
Thanks,
Stephan
