Swift 3：删除重复项/在uitableviewcell中将它们分组为1

Question

我正在尝试删除从外部数据库中提取的重复条目/将它们组合为一个。最初，我的sql查询有一个group子句。当我将它用作组子句时，查询工作正常，但不合适。然后我从查询中删除了group子句，它现在显示了重复的条目。

我有四个区域： - 北，东，南，西和所有

默认显示所有区域。现在可能有一个出现在多个地区的个人资料。因此，当它作为默认加载 - 所有区域时，配置文件只应出现在那里，但是当我们在区域上选项卡时，如果配置文件属于该区域，则配置文件也应显示在那里。

在他们的时刻，它显示所有随机。有些配置文件可以在多个区域中使用，它们确实会出现，有些则不会出现。某些仅在一个区域内的配置文件确实出现在两个区域中。

我不知道如何分享代码或屏幕截图，但很高兴提供更多细节来查看电话。

由于

我的代码：

 func removeDuplicate (sourceArray: [String]) -> [String] {
    var uniqueArray:[String] = []
    for object in sourceArray {
        if !uniqueArray.contains(object)
        {
            uniqueArray.append(object)
        }
    }
    return uniqueArray

Answer 1

根据我的知识，如果你想从数组中删除重复数据，那么请使用以下逻辑与{if !$priceDisplay || $priceDisplay == 2} {assign var='productPrice' value=$product->getPrice(true, $smarty.const.NULL, $priceDisplayPrecision)} {assign var='productPriceWithoutReduction' value=$product->getPriceWithoutReduct(false, $smarty.const.NULL)} {elseif $priceDisplay == 1} {assign var='productPrice' value=$product->getPrice(false, $smarty.const.NULL, $priceDisplayPrecision)} {assign var='productPriceWithoutReduction' value=$product->getPriceWithoutReduct(true, $smarty.const.NULL)} {/if}

datatype

<强>输出

[1,2,5,8,3]

替换此行

func removeDublicate (sourceArray: [Int]) -> [Int] {
    var uniqueArray:[Int] = []
    for object in sourceArray {
        if !uniqueArray.contains(object)
        {
            uniqueArray.append(object)
        }
    }
    return uniqueArray
}

let testing = removeDublicate(sourceArray: [1,2,2,5,1,8,3,1,2,8,5])
print(testing)

有了这个

let tableObjects:StorageSubCatagoriezTwoNorth = subCatagorizeDataTwoN[indexPath.row]

为所有地区做这件事

在swift 3 中，您可以使用此代码从数组中删除重复项。只需要这么多代码。 试试此代码..

import UIKit

class ViewController2: UIViewController {

   var myArray: [Int] = [1,2,3,4,3,2,5,7,5,8]

   override func viewDidLoad()
   {
       super.viewDidLoad()

       let uniqueArray = Array(Set(self.myArray))
       print(uniqueArray) // This print result will be [2, 4, 5, 7, 1, 8]
   }
}

<强>输出

[2,4,5,7,1,8]
