解决方案

错误信息很清楚，请阅读.引用:

<块引用>

由于未捕获的异常而终止应用'NSInternalInconsistencyException'，原因:'无效更新:无效第 0 节中的行数.更新后的现有部分 (1) 必须等于更新前包含在该节中的行 (11)，加上或减去从该部分插入或删除的行数(插入 1 个，0 已删除)并加上或减去移入或移出的行数该部分(0 移入，0 移出).

它说:

  • 更新(插入/删除)后，第 0 部分中有 1 个单元格，
  • 但是在你更新表格视图之前，你有 11 个单元格，然后你插入了 1 个单元格，因此它需要 11+1 个单元格，而不是 1

问题是 0 部分的单元格数量等于 nameData.count.还有你的代码(删除了不相关的部分)......

self.nameData.removeAllObjects() <----- (删除)var tempObject : NSDictionary;对于 var i=0;我＜jsonArray.count;我++ {var jsonDict = jsonArray[i] 作为 NSDictionaryvar name = jsonDict.valueForKey("name")！作为 NSStringself.nameData.insertObject(name, atIndex: 0) <----- (插入)让 indexPath = NSIndexPath(forRow: 0, inSection: 0)self.tableView.insertRowsAtIndexPaths([indexPath],withRowAnimation: .Fade) <------(插入)}

... 从 self.nameData 中删除所有对象，但不会从表视图中删除.

表视图单元格和您的后备存储未同步.

重新加载数据

删除 self.tableView.insert... 行并将 self.tableView.reloadData() 放在 for 循环之后.它会重新加载整个表格视图.

self.nameData.removeAllObjects()var tempObject : NSDictionary;对于 var i=0;我＜jsonArray.count;我++ {var jsonDict = jsonArray[i] 作为 NSDictionaryvar name = jsonDict.valueForKey("name")！作为 NSStringself.nameData.insertObject(name, atIndex: 0)让 indexPath = NSIndexPath(forRow: 0, inSection: 0)}self.tableView.reloadData()

或者只重新加载一个部分.

func reloadSections(_部分:NSIndexSet)

删除项目和然后插入

如果您不想重新加载所有单元格(整个表格视图)，您必须记住，您的数据后备存储必须与表格视图保持同步.换句话说 - 如果您确实从表格视图中删除了单元格，则必须将其从您的后备存储中删除.如果您将单元格插入表格视图，则必须将其插入后备存储.反之亦然.

在您的情况下，您调用 self.nameData.removeAllObjects()，但您没有删除这些对象的表视图单元格.你应该打电话...

func deleteItemsAtIndexPaths(_ indexPaths: [NSIndexPath])

... 在 self.tableView 上，用于从 self.nameData 中删除的所有对象.

如果你做了很多 deleteItems.../insertItems/... 调用，最好将它们包装在 performBatchUpdates(_:completion:) 中:>

func performBatchUpdates(_ updates: (() -> Void)?,完成完成:((Bool) -> Void)?)

<块引用>

将多个插入、删除、重新加载和移动操作作为一个组进行动画处理.

解决方案

It's pretty clear error message, just read it. Quote:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (11), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).

It says:

  • after the update (insert/delete) you've got 1 cell in section 0,
  • but before you did update the table view, you had 11 cells there, then you did insert 1 cell, thus it expects 11+1 cells, not 1

Problem is that number of cells in section 0 equals to nameData.count. And your code (removed unrelated parts) ...

self.nameData.removeAllObjects()   <----- (delete)

var tempObject : NSDictionary;

for var i=0; i < jsonArray.count; i++ {
  var jsonDict = jsonArray[i] as NSDictionary
  var name = jsonDict.valueForKey("name")! as NSString
  self.nameData.insertObject(name, atIndex: 0) <----- (insert)
  let indexPath = NSIndexPath(forRow: 0, inSection: 0)
  self.tableView.insertRowsAtIndexPaths([indexPath],
    withRowAnimation: .Fade)  <------ (insert)
}

... removes all objects from self.nameData, but not from table view.

Table view cells and your backing store is not synced.

Reload Data

Remove self.tableView.insert... line and place self.tableView.reloadData() just after the for loop. It reloads the whole table view.

self.nameData.removeAllObjects()

var tempObject : NSDictionary;

for var i=0; i < jsonArray.count; i++ {
  var jsonDict = jsonArray[i] as NSDictionary
  var name = jsonDict.valueForKey("name")! as NSString
  self.nameData.insertObject(name, atIndex: 0)
  let indexPath = NSIndexPath(forRow: 0, inSection: 0)
}
self.tableView.reloadData()

Or reload just one section.

func reloadSections(_ sections: NSIndexSet)

Delete Items & Then Insert

If you do not want to reload all cells (whole table view), you must keep in mind that your backing store for data must be kept in sync with table view. In other words - if you do remove cell from table view, you must remove it from your backing store. If you do insert cell into table view, you must insert it into backing store. And vice versa.

In your case, you call self.nameData.removeAllObjects(), but you didn't delete table view cells for these objects. You should call ...

func deleteItemsAtIndexPaths(_ indexPaths: [NSIndexPath])

... on self.tableView for all objects you did remove from self.nameData.

If you do lot of deleteItems.../insertItems/... calls, it's good to wrap them in performBatchUpdates(_:completion:):

func performBatchUpdates(_ updates: (() -> Void)?,
  completion completion: ((Bool) -> Void)?)

Animates multiple insert, delete, reload, and move operations as a group.
