解析類貫穿 For 循環

Question

我的應用程序使用 Parse.com 提供大部分服務。 主屏幕有一個 PFTableViewController，顯示某個類的所有對象。 我想將所有這些添加為 NSUserActivity，所以我知道我需要通過 for 循環來運行它，但是對於我的生活，無法想出如何通過循環運行該類以從將類轉換為 NSUserActivity。

到目前為止，我在設置桌子之前所擁有的東西。

- (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;
}

似乎沒有真正的 API ......請參閱此鏈接以獲取可能的解決方法：
