Saving data to plist per object or person - ios

Question

I am trying to save data to the plist in my app per person, but it save it to everyone, so for example if I have a field for eye color and I enter Brown in the textfield for John Doe, it save Brown for everyone else as well, is there a way to save this info per person in the app instead using plist? I have had no luck trying:
-(NSString *)pathofFile{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsfolder = [paths objectAtIndex:0];
return [docsfolder stringByAppendingFormat:#"data.plist"];
}
Here is the code I have in my view did load:
- (void)viewDidLoad {
[self loadPerson];
[super viewDidLoad];
NSString *filepath = [self pathofFile];
if ([[NSFileManager defaultManager]fileExistsAtPath:filepath]) {
NSArray *array = [[NSArray alloc]initWithContentsOfFile:filepath];
Drinfo.text = [array objectAtIndex:0];
[array release];
}
UIApplication *app = [UIApplication sharedApplication];
[[NSNotificationCenter defaultCenter]addObserver:self selector:#selector(applicationWillTerminate:) name: UIApplicationWillTerminateNotification object:app];
and here is what I have as part of my saveperson method:
NSMutableArray *array = [[NSMutableArray alloc]init];
[array addObject:self.Drinfo.text];
[array writeToFile:[self pathofFile] atomically:YES];
[array release];

You could use a plist just create a NSDictionary for each person inside the plist and add the colour string to that. The steps would be something like
Open up the plist from file, set it to be a NSDictionary and make sure its a mutable copy.
Create a new NSMutableDictionary and add any attributes to that e.g. eye colour.
Add that mutable dictionary to your plist dictionary with the key set to the persons name
Save the plist
