indexPath.row始终返回零

Question

我有两个集合视图，一个显示名称，另一个显示相应人员的年龄。此数据以“ [[[名称]，“年龄”]，[“名称”：“ Daniel”，“年龄”：“ 20”]，[“名称”：“杰克”的形式存储在字典数组中，“ Age”：“ 20”]]。此数据来自CSV文件，因此第一个元素是标头。在collectionView cellForItemAtIndexPath内部，我正在检查集合视图并提供基于行号的数据，例如cell [indexPath.row] [“ Name”]和cell2 [indexPath.row] [“ Age”]。但是，indexPath.row始终返回零，因此我只得到标头-

如何解决此问题？这是我的代码-

func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
    return 2
}

func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return 1
}

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    if collectionView == self.nameCollectionView {
        let nameCell = collectionView.dequeueReusableCellWithReuseIdentifier("NameCell", forIndexPath: indexPath) as! NameCell

        nameCell.data.text = self.data?[indexPath.row]["Name"]
        println(indexPath.row)

        return nameCell
    }
    else{
        let ageCell = collectionView.dequeueReusableCellWithReuseIdentifier("AgeCell", forIndexPath: indexPath) as! AgeCell

        ageCell.data.text = self.data?[indexPath.row]["Age"]



        return ageCell
    }

}

Answer 1

作为您的代码，您只设置numberOfItemsInSection了1，那么您总是得到第0个索引。使存在动态值，例如返回Array.count。

func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return self.data.count  // here you need to set dynamic count of array
}

更新：

如果遵循，numberOfSectionsInCollectionView则使代码如下所示cellForRow：

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    if collectionView == self.nameCollectionView {
        let nameCell = collectionView.dequeueReusableCellWithReuseIdentifier("NameCell", forIndexPath: indexPath) as! NameCell

        nameCell.data.text = self.data?[indexPath.section]["Name"]
        println(indexPath.section)

        return nameCell
    }
    else{
        let ageCell = collectionView.dequeueReusableCellWithReuseIdentifier("AgeCell", forIndexPath: indexPath) as! AgeCell

        ageCell.data.text = self.data?[indexPath.section]["Age"]



        return ageCell
    }

}
