I've been trying to load images from a url using ASIHTTPRequest but I always come up with a blank UIImage. I think it might have something to do with iOS automatically choosing the @2x named version of images or vica versa.
[ASIHTTPRequest setDefaultCache:[ASIDownloadCache sharedCache]];
NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]];
NSURL *url = [NSURL URLWithString:url_string];
__block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadCache:[ASIDownloadCache sharedCache]];
[request setCachePolicy:ASIAskServerIfModifiedCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy];
[request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy];
[request setSecondsToCache:86400];
[request setDelegate:self];
[request setCompletionBlock:^{
NSLog(@"Successful Update");
[self makeAssignment];
}];
[request setFailedBlock:^{
NSError *error = [request error];
NSLog(@"%@", [error localizedDescription]);
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Update Failed"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}];
[request startAsynchronous];
NSLog(@"%@", url_string);
The makeAssignment method is below.
NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]];
NSURL *url = [NSURL URLWithString:url_string];
downloadedImage = [[UIImage alloc] initWithContentsOfFile:[[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]];
NSLog(@"%@", downloadedImage);
NSLog(@"%@", [[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]);
Nothing I do, including naming images @2x on the server or providing both versions, gets it to load. Any ideas? Has anyone done this before? When I load them locally (from within the package) I don't have any issues.
Thanks!
