Question

If I want to display all the objects, I use the code below. But if I only want to display the objects where the value for the key “Favorite” = “Yes”, then what? Example of this would be great.

- (void)viewDidLoad
{
[super viewDidLoad];    

NSString *path = [[NSBundle mainBundle]
                    pathForResource:@"Objects" ofType:@"plist"];

sortedObjects = [[NSMutableArray alloc]initWithContentsOfFile:path];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [sortedObjects count];
}

Ps. The Property List is an array with dictionaries.

You need to create a new array, lets call it filtered, that you create by filtering sortedObjects, and use that to populate the table.

NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF.Favorite == %@", @"Yes"];
NSArray *filtered = [sortedObjects filteredArrayUsingPredicate:pred];
