Ios 分析Koloda库中的数据-无法在视图中显示

有人能告诉我我做错了什么吗？ 可能很多，因为我是新手，但期待着解决这个问题

我使用Koloda Library（）将一组对象提取到卡中，这样每张卡都可以从我的数据库中获取一行。我已经看到了Alamofire的网络示例，并尝试了使用相同示例实现解析的自己的代码。它从Parse中获取对象，但我无法将它们显示在卡片中。奇怪的是，实际上我没有错误，控制台显示“成功检索到5个对象”，但这只是loadData（）函数

我将在那里显示大量笔尖文本

我基本上想要实现什么： 我有（MyView.xib，MyView.swift）提供标签。 （我想要的是从数组中检索到xib标签中的文本）

我正在检索对象，但未能成功将其显示到卡中：

Successfully retrieved 5 posts.
Optional("EvUICgRQ6E")
Optional("5kC0FLKQON")
Optional("1Uyxb2M1Et")
Optional("aeJpRCG7Qn")
Optional("GDmGh3IULm")

一些错误： 如果我返回“numberOfCards”-我将得到以下错误：

fatal error: Array index out of range
(lldb) 

如果我返回：“返回UInt（self.data.count）” 我没有收到任何错误，但卡根本没有显示

我是一个有点新手，但指出了一个好的方向，我将能够完成它。

这是我的ViewController.swift代码：

MyView有自己的nib。 还将在我的项目中放置一些图片：

有人知道怎么做吗？我已经挣扎了10天，但仍然没有让它发挥作用

我将非常感谢您的帮助和提示

更新：我现在对loadData（）使用此函数

使用此变量

你能在GitHub上添加一个问题吗？

谢谢

能否在GitHub上添加一个问题？

谢谢

我也遇到了类似的问题，卡没有获得数据。显然，这是一个问题，我是如何调用捆绑。更正下面的Swift 3.0代码

func koloda(_ koloda: KolodaView, viewForCardAt index: Int) -> UIView {

    let bundle = Bundle(for: MyView.self) // This gets the correct bundle for your class, as sometimes you might have many bundles.
    let nib = UINib(nibName: String(describing: MyView.self), bundle: bundle)
    let view = nib.instantiate(withOwner: self, options: nil)[0] as! MyView

    return view
}
