Question

我在iOS上使用Parse。https://www.parse.com/docs/downloads/然而，我在更新指定objectID上的bool值时遇到了困难，如图所示。

我可以通过这样的设置添加新行。但现在，我想更新指定objectID上的bool值。我想知道该怎么做。

PFObject *gameScore = [PFObject objectWithClassName:@"GameScore"];
[gameScore setObject:[NSNumber numberWithBool:NO] forKey:@"cheatMode"];

我找到了一个办法。

PFQuery *query = [PFQuery queryWithClassName:@"test"];
    [query whereKey:@"objectId" equalTo:objectIDForReport];
    [query getFirstObjectInBackgroundWithBlock:^(PFObject * reportStatus, NSError *error)        {
        if (!error) {
            // Found UserStats
            [reportStatus setObject:[NSNumber numberWithBool:YES] forKey:@"report"];
            // Save
            [reportStatus saveInBackground];
        } else {
            // Did not find any UserStats for the current user
            NSLog(@"Error: %@", error);
        }
    }];
