What you can do is:-

Suppose you have parsed your xml and stored data in array say ‘dataArray‘

Now you have to save your dataArray in NSUserDefaults

NSUserDefaults *pref1=[NSUserDefaults standardUserDefaults];
[pref1 setObject:dataArray forKey:@"parseData"];    
[pref1 synchronize];

Whenever you have to use this data you can extract it like:-

NSUserDefaults *pref1=[NSUserDefaults standardUserDefaults];
NSArray *dataArray=[pref1 objectForKey:@"parseData"];
