How to get exact data from NSUserDefaults in Objective C,iOS?

Question

I have NSMutableArray and I am trying to save that array in NSUserDefaults.Here is my code :

to save :

NSUserDefaults *currentDefaults = [NSUserDefaults standardUserDefaults];
[currentDefaults setObject:[NSKeyedArchiver archivedDataWithRootObject:userSession.transactionArray] forKey:@"TransId"];
[currentDefaults synchronize];

to retrieve :

NSUserDefaults *currentDefault = [NSUserDefaults standardUserDefaults];
NSData *dataRepresentingSavedArray = [currentDefault objectForKey:@"TransId"];
NSMutableArray *oldSavedArray = [NSKeyedUnarchiver unarchiveObjectWithData:dataRepresentingSavedArray];
userSession.transactionArray = [NSArray arrayWithArray:oldSavedArray];

But, I am getting my array in log,

"<NSIndexPath: 0x160f8640> {length = 2, path = 0 - 0}",
"<NSIndexPath: 0x1602bd70> {length = 2, path = 0 - 1}",
"<NSIndexPath: 0x16026900> {length = 2, path = 0 - 2}",
"<NSIndexPath: 0x14f01dd0> {length = 2, path = 0 - 3}"

How to get actual data from this.Can anybody help me to get this value properly? Thanks in advance.

Each and every object in your array has to conform to protocol in order for array to be saved/retrieved correctly. — Rok Jarc, Jul 29 '15 at 12:46

 NSArray *aviArray=[[NSArray alloc] initWithObjects:@"A",@"B",@"C", nil];
[[NSUserDefaults standardUserDefaults] setObject:aviArray forKey:@"Arraykey"];
[[NSUserDefaults standardUserDefaults] synchronize];

 NSLog(@"%@",[[[NSUserDefaults standardUserDefaults] objectForKey:@"Arraykey"] objectAtIndex:0]); 

 NSLog(@"%@",[[NSUserDefaults standardUserDefaults] objectForKey:@"Arraykey"]);

This is similar to: NSKeyedArchiver archivedDataWithRootObject:

You're missing the implementations of initWithCoder: and encodeWithCoder:. One of the answers describes how to write those.
