19 |  - (void) didFinishDownload:(NSNumber*)idx {
20 | 	NSLog(@"%d download: %@", [idx intValue], [downloads dataAsStringAtIndex: [idx intValue]]);

28 | 29 | h2. BlueBadge class 30 | 31 | It uses CoreGraphic to draw a blue badge similar to the mail count in Mail.app. To initialize: 32 | 33 | 

34 | BlueBadge *blueBadge = [[BlueBadge alloc] initWithFrame: rect];
35 | [cell addSubview:blueBadge];
36 | [blueBadge release];
37 |
38 | 39 | When you need to update the count: 40 | 

41 | [blueBadge drawWithCount: numOfMail];
