无法从 Parse Local Datastore 检索本地数据(固定对象) [英] Can't retrieve local data (pinned objects) from Parse Local Datastore

问题描述

重新打开应用后，我无法检索本地数据(固定对象).

I can't retrieve the local data (pinned objects) after re-open the app.

我的控制器中有此代码:

I have this code in my controller:

- (IBAction)btnAddTouched:(id)sender
{
    PFObject *object = [PFObject objectWithClassName:@"Foobar"];

    [object setValue:[[NSDate date] description] forKey:@"data"];

    [object pinInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (succeeded) {
            NSLog(@"Pinned OK");
        }else{
            NSLog(@"Erro: %@", error.localizedDescription);
        }
    }];
}

- (IBAction)btnLoadTouched:(id)sender
{
    PFQuery *query = [PFQuery queryWithClassName:@"Foobar"];

    [query fromLocalDatastore];

    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (!error) {
            NSLog(@"%@", objects);
        }else{
            NSLog(@"Erro: %@", error.localizedDescription);
        }
    }];
}

重现步骤:

1. 使用 btnAddTouched: 固定一些对象；
2. 关闭应用程序(停止调试)；
3. 再次打开应用(再次构建)；
4. 尝试使用 btnLoadTouched 加载固定数据；

1. Pin some objects with btnAddTouched:;
2. Close the app (stop debbuging);
3. Open the app again (build again);
4. Try Load pinned data with btnLoadTouched;

它正在用 localId: (null):

"<Foobar: 0x15d42770, objectId: new, localId: (null)> {\n    data = \"2014-12-15 21:00:05 +0000\";\n}"
    )

之后 pinInBackgroundWithBlock: 将不再起作用.然后永远不会调用这些块.

And after that the pinInBackgroundWithBlock: won't work anymore. The blocks is never called then.
