Question

我在系统设置user发布帖子（PFObject）并发布到tableview控制器，所有其他用户都将该帖子发布到tableview。我希望能够抓住一个用户的帖子（PFObjects）并能够在单独的tableview中显示它们，以便user可以看到他们发布的内容。

这就是我发布PFObject的方式：

PFUser *user = [PFUser currentUser];

    PFObject *quoteNew = [PFObject objectWithClassName:@"New"];
    [quoteNew setObject:user forKey:@"author"];
    [quoteNew setObject:[[self quoteText] text] forKey:@"quoteText"];
    [quoteNew setObject:[[self attributionTitle] text] forKey:@"title"];
    [quoteNew setObject:@"Story" forKey:@"cato"];

     PFACL *postACL = [PFACL ACLWithUser:[PFUser currentUser]];
    [postACL setPublicReadAccess:YES];
    [quoteNew setACL:postACL];

这是我检索到表格视图的方式：

-(id)initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];
    if (self) {
        // Customize the table

        // The className to query on
        self.parseClassName = @"New";
       // self.className2 = @"Story";

        // The key of the PFObject to display in the label of the default cell style
        self.textKey = @"title";

        self.User = @"cato";
       // self.textKey2 = @"title";

        // Uncomment the following line to specify the key of a PFFile on the PFObject to display in the imageView of the default cell style
         //self.imageKey = @"image";

        // Whether the built-in pull-to-refresh is enabled
       // self.pullToRefreshEnabled = YES;

        // Whether the built-in pagination is enabled
        self.paginationEnabled = YES;

        // The number of objects to show per page
        self.objectsPerPage = 100;
    }
    return self;
}

您必须覆盖queryForTable方法以设置查询参数

- (PFQuery *)queryForTable {
    PFQuery *query = [PFQuery queryWithClassName:self.parseClassName];

    [query whereKey:@"author" equalTo:@"name"];  //where you set the username to the specific user to get only this user's post. 
    // If no objects are loaded in memory, we look to the cache first to fill the table
    // and then subsequently do a query against the network.

   if (self.objects.count == 0) {
        query.cachePolicy = kPFCachePolicyCacheThenNetwork;
    }

    [query orderByDescending:@"createdAt"];

    return query;
}

在PFQueryTableViewController下查看https://www.parse.com/docs/ios_guide#ui-tables/iOS。
