July 13th, 2009
Wouldn’t it be cool if you could your next iPhone app could see if the user had mail, had a new AIM message, or even a new cal appointment? Well now you can, the following objective-c code will tell you the badge number of any application on the users springboard.
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:@"/private/var/mobile/Library/Caches/com.apple.springboard.displaystate.plist"]; if(dict == nil) return NSLog(@"not able to read displaystate"); NSDictionary *appDict = (NSDictionary *)[dict valueForKey:@"com.chrisalvares.CALocationService"]; if(appDict == nil) return NSLog(@"application was not found"); NSNumber *badgeNumber = [appDict objectForKey:@"SBApplicationBadgeKey"]; if(badgeNumber == nil) return NSLog(@"BadgeNumber was not found");
