how to read and write to plist

we can use the code below

- (void)readPlist
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //1
NSString *documentsDirectory = [paths objectAtIndex:0]; //2

NSString *path = [documentsDirectory stringByAppendingPathComponent:@"Contacts.plist"];
listOfItems = [[NSMutableArray alloc] initWithContentsOfFile:path];

}

- (void)writeToPlist
{

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //1
NSString *documentsDirectory = [paths objectAtIndex:0]; //2
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"Contacts.plist"];

[listOfItems writeToFile:path atomically:YES];

}
