Saving data from Twitter feed parsed with JSON into Plist - objective-c

Question

I have a UITableView populated by a feed from searchtwitter.com. I also have a details table with an image and UILabel. I have all this working, but I want to add a UIButton on the detail page that will save the UIImage and the label into a property list. I'm very new to this; here is what I have so far (not working).
- (IBAction)SaveFriend:(id)sender
{
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [path objectAtIndex:0];
NSString *plistPath = [documentDirectory stringByAppendingPathComponent:#"TwitterFriends.plist"];
NSDictionary * tweet = [[NSDictionary alloc]init];
NSString *text = [tweet objectForKey:#"from_user"];
NSString *user = [tweet objectForKey:#"from_user_name"];
personName.text = text;
personInfo.text = user;
// create dictionary with values in UITextFields
NSDictionary *plistDict = [NSDictionary dictionaryWithObjects: [NSArray arrayWithObjects: personName, personInfo, nil] forKeys:[NSArray arrayWithObjects: #"Name", #"info", nil]];
NSString *error = nil;
// create NSData from dictionary
NSData *plistData = [NSPropertyListSerialization dataFromPropertyList:plistDict format:NSPropertyListXMLFormat_v1_0 errorDescription:&error];
// check is plistData exists
if(plistData)
{
// write plistData to our Data.plist file
[tweet writeToFile:plistPath atomically:YES];
}
else
{
NSLog(#"Error in saveData: %#", error);
[error release];
}
}

Instead of using a .plist, try using an NSArray or NSMutableArray and then the writeToFile method. For example:
NSMutableArray *temp = [NSMutableArray new];
[temp addObject:image];
[temp addObject:label];
[temp writeToFile:[self saveFilePath:#"filename"] atomically:YES];
//Returns the saved information path
- (NSString*) saveFilePath: (NSString *) add
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *path = [paths objectAtIndex:0];
NSString *filename = [path stringByAppendingPathComponent:add];
return filename;
}
