代码:

    func addGroupTopicItem(groupTopicItem:GroupItem) {
        if !self.existedGroupTopic(groupTopicItem.id) {
            dispatch_async(dispatch_get_main_queue(), { () -> Void in
                self.groupTopicItemList.append(groupTopicItem)
                let insertedRowIdx = self.groupTopicItemList.count 1

                let curRealRowNum = self.tableView.numberOfRowsInSection(0)
                let curRealRowMaxIdx = curRealRowNum – 1
                if insertedRowIdx > curRealRowMaxIdx {
                    self.tableView.reloadData()
                } else {
                    //insert row
                    self.tableView.beginUpdates()
                    let insertedRowIndexPath:NSIndexPath = NSIndexPath(forRow: insertedRowIdx, inSection: 0)
                    self.tableView.insertRowsAtIndexPaths([insertedRowIndexPath], withRowAnimation: UITableViewRowAnimation.Bottom)
                    self.tableView.endUpdates()
                }
               
//                //insert row
//                self.tableView.beginUpdates()
//                let insertedRowIndexPath:NSIndexPath = NSIndexPath(forRow: insertedRowIdx, inSection: 0)
//                self.tableView.insertRowsAtIndexPaths([insertedRowIndexPath], withRowAnimation: UITableViewRowAnimation.Bottom)
//                self.tableView.endUpdates()
            })
        }

    }

‘NSInternalInconsistencyException’, reason: ‘Invalid update: invalid number of rows in section 0.  The number of rows contained in an existing section after the update (50) must be equal to the number of rows contained in that section before the update (50), 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).’

搜:

去改为:

                self.tableView.beginUpdates()
                self.groupTopicItemList.append(groupTopicItem)
                let insertedRowIdx = self.groupTopicItemList.count 1
                let insertedRowIndexPath:NSIndexPath = NSIndexPath(forRow: insertedRowIdx, inSection: 0)
                self.tableView.insertRowsAtIndexPaths([insertedRowIndexPath], withRowAnimation: UITableViewRowAnimation.Bottom)
                self.tableView.endUpdates()

结果:

有时候还是会出错:

‘NSInternalInconsistencyException’, reason: ‘Invalid update: invalid number of rows in section 0.  The number of rows contained in an existing section after the update (4) must be equal to the number of rows contained in that section before the update (4), 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).’

最后还是无法解决,最终暂时用了:

self.tableView.reloadData()
