Question

我有一个tableview，按照从最旧到最新的顺序列出了大约10个单元格。当我打开＆＃34;编辑模式＆＃34;并删除单元格，一切似乎都正常工作。

但我创建了一些函数，根据各种属性将这些单元格置于不同的顺序。当我在这些不同的排序顺序中使用编辑模式时，错误的单元格似乎被删除。

以下是我的某个排序函数的代码。

这是我删除功能的代码。

func sortPokemonListbyAveIV(){
        self.pokemonList.sortUsingComparator{
            (obj1: AnyObject, obj2: AnyObject) -> NSComparisonResult in
            let first = obj1 as! NSDictionary
            let second = obj2 as! NSDictionary
            var firstIVRange = ""
            var secondIVRange = ""
            if((first["iv"] as! String).containsString("Sorry")){
                firstIVRange = "IV: 1 - 2%"
            } else {
                firstIVRange = (first["iv"] as! String).stringByReplacingOccurrencesOfString("--", withString: "-")
            }
            if((second["iv"] as! String).containsString("Sorry")){
                secondIVRange = "IV: 1 - 2%"
            } else {
                secondIVRange = (second["iv"] as! String).stringByReplacingOccurrencesOfString("--", withString: "-")
            }
            // let firstIVRange = first["iv"] as! String
            // let secondIVRange = second["iv"] as! String
            let firstAveIV = self.avgIV(firstIVRange)
          //  print(firstIVRange)
            let secondAveIV = self.avgIV(secondIVRange)
            let result = firstAveIV - secondAveIV
            return (result < 0) ? .OrderedDescending
                : (result == 0) ? .OrderedSame : .OrderedAscending
        }
    }

我怀疑我需要编辑删除功能代码以考虑tableview中当前的活动排序顺序。我不太确定如何做到这一点。

Answer 1

您不需要在tableView.reloadData()之后致电tableView.deleteRowsAtIndexPaths。由于调用reloadData将触发整组tableView委托和数据源方法，如cellForRowAtIndexPath，numberOfRowsInSection等。

在我求助表顺序后，编辑模式将删除错误的单元格
