Ios 一个Viewcontroller中的多个CollectionView会导致索引超出范围错误

我尝试在一个Viewcontroller中使用三个CollectionView。我按照以下方法解析数据： 在底部，我根据位置将数据添加到右侧列表中（此部分有效）

在我的NumbersofItemsInSection方法中，我做了以下同样有效的工作：

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    if collectionView == self.acceptedEventscv{
    return acceptedEvents.count
    }else if collectionView == self.storedEventscv{
        return storedEvents.count
    }else if collectionView == self.myEventscv{
        return myEvents.count
    }else{
        return 0
    }
    }

在我的CellForRowaItem方法中，我尝试了以下方法

func collectionView(_ collectionView: UICollectionView, 
 cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
 if collectionView == self.acceptedEventscv{
 let cell = 
  collectionView.dequeueReusableCell(withReuseIdentifier: 
"acceptedEventsCell", for: indexPath) as! 
 acceptedEventsCollectionViewCell
 let eo = acceptedEvents[indexPath.row]
  cell.eventName.text = eo.eventName

  let items = eo.date!.components(separatedBy: " ")//Here replase 
  space with your value and result is Array.
 //Direct line of code
 //let items = "This is my String".components(separatedBy: " ")
 let date = items[0]
let time = items[1]
cell.date.text = date
cell.time.text = time

getUserNameAge(label: cell.usernameAge)
return cell
}else {
  let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "savedEventsCell", for: indexPath) as! savedEventsCollectionViewCell
  let eo = acceptedEvents[indexPath.row]
  cell.eventName.text = eo.eventName

  let items = eo.date!.components(separatedBy: " ")//Here replase space with your value and result is Array.
  //Direct line of code
  //let items = "This is my String".components(separatedBy: " ")
  let date = items[0]
  let time = items[1]
  cell.date.text = date
  cell.time.text = time


  getUserNameAge(label: cell.usernameAge)

  return cell
}

}

问题是，如果Second CollectionView中有更多项，我总是会出现以下错误：

线程1:致命错误：索引超出范围

在这一行代码中：

let eo = acceptedEvents[indexPath.row]

---

cellForItemAt

也必须是

if collectionView == self.acceptedEventscv{
  let item = acceptedEvents[indexPath.row]
   ----
  return cell
}else if collectionView == self.storedEventscv{
    let item = storedEvents[indexPath.row]   
    ----
    return cell
}else {
     let item = myEvents[indexPath.row] 
     ----
     return cell  
}

在您的情况下，现在发生的情况是，在这两种情况下，您访问相同的数组

acceptedEvents

，其中

numberOfItemsInSection

中返回的计数可能不同

if collectionView == self.acceptedEventscv{
  let item = acceptedEvents[indexPath.row]
   ----
  return cell
}else if collectionView == self.storedEventscv{
    let item = storedEvents[indexPath.row]   
    ----
    return cell
}else {
     let item = myEvents[indexPath.row] 
     ----
     return cell  
}
