This class will help you access key chain as much like NSMutableDictionary. Usage: NSData *someData = ... ZKeyChain *keyChain = [ZKeyChian keyChianWithService:@"YourService"]; [keyChain setString:@"user@domain.com" forKey:@"userid"]; [keyChain setData:someData forKey:@"data"]; [keyChain setImage:nil forKey:@"image"]; // remove data from key API: - (void)setData:(id)aData forKey:(NSString *)aKey; - (id)dataForKey:(NSString *)aKey; - (void)setString:(NSString *)aString forKey:(NSString *)aKey; - (NSString *)stringForKey:(NSString *)aKey; - (void)setDictionary:(NSDictionary *)aDictionary forKey:(NSString *)aKey; - (NSDictionary *)dictionaryForKey:(NSString *)aKey;
