Objective c 如何访问Parse.com对象'；在查询返回键/值对后，是否为？

我意识到这个问题可能有一个简单的答案，但我在Parse.com上查阅了所有相关文档和许多其他资源后，并没有找到它。下面是我正在查看的代码片段：

    PFUser *currentUser = [PFUser currentUser];


    PFQuery *query = [PFQuery queryWithClassName:@"ProfileInfo"];
    [query whereKey:@"userID" equalTo:[PFUser currentUser]];

    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {

        /* What is the easiest way to pull the key/value pairs from the returned NSArray of PFobjects here? */
    }];

非常感谢您的帮助，提前谢谢

for(PFObject *pfObject in objects){
    NSString *someValue = [pfObject objectForKey:@"someKey"];

    //or if it's a number
    NSNumber *someNumber = [pfObject objectForKey:@"someOtherKey"];
}
