ios - NSUserDefaults Saving only last entered data -

i saving textfield text using nsuserdefaults on button click in viewcontroller2 code

buttonclick() {     nsuserdefaults *userdefaults =[nsuserdefaults standarduserdefaults];     [userdefaults setobject:keywordfield.text forkey:@"keywords"];     [userdefaults synchronize]; }  viewdidload method retrieving -(void)viewdidload {  nsuserdefaults *userdefaults =[nsuserdefaults standarduserdefaults]; [keywordarray addobject:[userdefaults objectforkey:@"keywords"]]; [userdefaults synchronize];  } 

here assigning keywordarray tableview cell.textlabel.text =[keywordarray objectatindex:indexpath.row];

first entered text(first) in textfield , click button showing in table      first second time entered text (second) in textfield , click button showing table       first       second here working fine. problem when come viewcontroller2 viewcontroller1. showing last entered value        second 

what going wrong here?

try this

- (ibaction)buttonclick:(id)sender {  [keywordarray addobject:keywordfield.text]; nsuserdefaults *userdefaults =[nsuserdefaults standarduserdefaults]; [userdefaults setobject:keywordarray forkey:@"keywords"]; [userdefaults synchronize]; [selt.tableview reload];  //reload table every time new text added }  -(void)viewdidload {  if([[nsuserdefaults standarduserdefaults] objectforkey:@"keywords"]==nil){   keywordarray = [[nsmutablearray alloc] init];  }  else{  keywordarray = [[nsuserdefaults standarduserdefaults] objectforkey:@"keywords"];  } }
