ios - 在解析中从用户获取 objectId

Question

我是解析新手，我正在尝试获取用户 objectId，但我似乎无法返回 objectId。我可以轻松返回用户名。这是我的查询:

                 PFQuery *query = [PFUser query];
                 [query whereKey:@"username" equalTo:[[PFUser currentUser] objectForKey:@"username"]];
                 [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
                     if (!error) {
                         if (objects.count) {
                             NSLog(@"%@", [objects lastObject]);

                         }
                }
            }];

这会返回如下内容:

<PFUser:9dcc65tsdr:(null)> {
    username = AEleQFdBx9jdtypfsQmLtzAvW;
}

如何返回介于 PFUser 和 (null) 之间的 objectId？

Answer 1

您可以像这样使用 object.objectId:

PFQuery *query = [PFUser query];
 [query whereKey:@"username" equalTo:[[PFUser currentUser] objectForKey:@"username"]];
 [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
     if (!error) {
         if (objects.count) {
             for (PFObject *object in objects){
                NSLog(@"Object ID: %@", object.objectId);
             }
         }
}
