 -(IBAction)AddToF
 {
    NSString *str=lblText.text;
[[NSUserDefaults standardUserDefaults] setObject:str forKey:@"preferenceName"];
 }

     NSString *savedValue = [[NSUserDefaults standardUserDefaults]
                        stringForKey:@"preferenceName"];
[super viewWillAppear:animated];
}

Can some guide me how to fix it.Thanks.

Answer 1

Store array in userDefault instead of string like bellow..

In AppDelegate.h file just declare variable…

NSUserDefaults  *userDefaults;
NSMutableArray *yourArray;
after...

In AppDelegate.m Fille in applicationDidFinishLonching: Method

userDefaults = [NSUserDefaults standardUserDefaults];
NSData *dataRepresentingtblArrayForSearch = [userDefaults objectForKey:@"yourArray"];
if (dataRepresentingtblArrayForSearch != nil) {
    NSArray *oldSavedArray = [NSKeyedUnarchiver unarchiveObjectWithData:dataRepresentingtblArrayForSearch];
    if (oldSavedArray != nil)
        yourArray = [[NSMutableArray alloc] initWithArray:oldSavedArray];
    else
        yourArray = [[NSMutableArray alloc] init];
} else {
    yourArray = [[NSMutableArray alloc] init];
}
[yourArray retain];

after when you want to insert Data in this UserDefaults Use Bellow Code…

[appDelegate.yourArray addObject:yourDataString];///set your value or anything which you want to store here...
NSData *data=[NSKeyedArchiver archivedDataWithRootObject:appDelegate.yourArray];
[appDelegate.userDefaults setObject:data forKey:@"yourArray"];
[appDelegate.userDefaults synchronize];

when you want to create AppDelegate object then use bellow code..

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

i hope this help you…
