objective c - Best way to store iPhone data (custom NSObject) -

i have nsmutablearray in store objects called "address". address nsobject 4-5 properties (nsstrings). nsmutablearray shall contain maximum of 15 address object.

what best way store array on iphone? core data? nsuserdefaults? should maybe store every address object itself, , not objects in 1 nsmutablearray? in case should on iphone?

thanks.

as @rog said, may use nsuserdefaults save data

& should make object follow protocal nscoding

for examplem if object "youobject"

@interface youobject: nsobject {  }  @property (nonatomic, copy) nsstring *uid; @property (nonatomic, copy) nsstring *name;  @end   //implement 2 method   - (id)initwithcoder:(nscoder *)decoder {   if (self = [super init]) {     self.title = [decoder decodeobjectforkey:@"uid"];     self.author = [decoder decodeobjectforkey:@"name"];   }   return self; }  - (void)encodewithcoder:(nscoder *)encoder {   [encoder encodeobject:title forkey:@"uid"];   [encoder encodeobject:author forkey:@"name"]; } 

then archive or unarchive using nsuserdefaults

//archive youobject *object = [youobject ....] nsdata *data = [nskeyedarchiver archiveddatawithrootobject:object ]; [[nsuserdefaults standarduserdefaults] setobject:data forkey:@"address"];  //unarchive nsdata *data = [[nsuserdefaults standarduserdefaults] objectforkey:@"address"]; youobject *object = (youobject *)[nskeyedunarchiver unarchiveobjectwithdata:data]; 

or if have youobject array, can save nsarray in same way;

//archive nsarray *addresses; nsdata *data = [nskeyedarchiver archiveddatawithrootobject:address ]; [[nsuserdefaults standarduserdefaults] setobject:data forkey:@"address"];  //unarchive nsdata *addressdata = [[nsuserdefaults standarduserdefaults] objectforkey:@"address"]; nsarray *addresses = (nsarray*)[nskeyedunarchiver unarchiveobjectwithdata:address];
