通过For循环解析Class运行

Question

我的应用使用 Parse.com 来提供大部分服务。主屏有一个PFTableViewController，显示某class的所有对象。我想将所有这些添加为 NSUserActivity，所以我知道我需要通过 for 循环运行它，但是对于我来说，想不出如何运行 class 通过循环将 class 中的每个项目添加到 NSUserActivity.

设置 table.

之前我已经知道了什么

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

        // The className to query on
        self.parseClassName = @"Prayers";

        // 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 = 20;

    }
    return self;
}
- (PFQuery *)queryForTable {
    NSLog(@"QUERY");
    PFQuery *query = [PFQuery queryWithClassName:@"Prayers"];

    // 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;
}

这似乎没有真正的 API...请参考此 link 以获得可能的解决方法：
