nskeyedarchiver

I was wondering whether or not it is possible to use the NSCoder method: - (void)encodeObject:(id)objv forKey:(NSString *)key to encode either an instance of NSArray or NSDictionary. If not how do you go about encoding them? I am trying to use NSKeyedArchived / NSKeyedUnarchiver to send data between phones using GameKit. I tried it and cannot seem to retrieve the string I stored in my array. The packet class I made comes through along with the packet type integer, but not the data in the array it seems. Thanks in advance! NSKeyedArchiver/Unarchiver should encode and decode NSArrays and

I'm unable to create an NSData object from a UIColor (with a pattern) created with the factory method [UIColor colorWithPatternImage:image] works fine for standard UIColor objects. Wondering if there is another way to save a UIColor with a pattern into Core Data. I am using the following code to archive the UIColor (with a pattern)... - (id)transformedValue:(id)value { NSData *data = [NSKeyedArchiver archivedDataWithRootObject:value]; return data; } and these are the errors I'm receiving... -[NSKeyedArchiver dealloc]: warning: NSKeyedArchiver deallocated without having had -finishEncoding

I'm trying to store an Integer and retrieve it using KeyChain. This is how I save it: func SaveNumberOfImagesTaken() { let key = "IMAGE_TAKEN" var taken = 10 let data = NSKeyedArchiver.archivedDataWithRootObject(taken) let query : [String:AnyObject] = [ kSecClass as String : kSecClassGenericPassword, kSecAttrAccount as String : key, kSecValueData as String : data ] let status : OSStatus = SecItemAdd(query as CFDictionaryRef, nil) } This is how I try to retrieve it: func CheckIfKeyChainValueExitss() -> AnyObject? { var key = "IMAGE_TAKEN" let query : [String:AnyObject] = [ kSecClass as String :

I have a struct containing a struct and an NSObject that I want to serialize into an NSData object: struct Packet { var name: String var index: Int var numberOfPackets: Int var data: NSData } var thePacket = Packet(name: name, index: i, numberOfPackets: numberOfPackets, data: packetData) How do I best serialize the Packet into an NSData , and how do I best deserialize it? Using var bufferData = NSData(bytes: & thePacket, length: sizeof(Packet)) of only gives me the pointers of name and data. I was exploring NSKeyedArchiver , but then I'd have to make Packet an object, and I'd prefer to keep it

This question already has an answer here: Saving UIColor to and loading from NSUserDefaults 8 answers I'm trying to program my code so that if the user presses the Night Button the background will turn black and stay black if the user closes the app. (Same goes for day mode.) Please note: I already coded buttons and when they press it, all of the scenes change to that mode. Here's my code where I'm going going to need the background color to be saved: (I need it in both if statements) if GlobalData.dayBool == true && GlobalData.night == false { backgroundColor = GlobalData.dayColor } if
