【中文标题】显示 TableView 部分标题和行 ios swift

【英文标题】：Show TableView Section Headers and Rows ios swift

【问题描述】：

我有一个包含对象的数组，我想在标题中显示组名，但在数组中某些组具有相同的名称，现在我想为同一组显示单个标题并创建行。

[
       
         "primary_dark_color": "#0d6d9f",
         "Groups": "A",
         "primary_color": "#03a9f4"
       ,
       
         "primary_dark_color": "#0d6d9f",
         "Groups": "B",
         "primary_color": "#03a9f4"
        ,
        
         "primary_dark_color": "#0d6d9f",
         "Groups": "A",
         "primary_color": "#03a9f4"
        ,
        
         "primary_dark_color": "#0d6d9f",
         "Groups": "B",
         "primary_color": "#03a9f4"
       ]

【参考方案1】：

要解决您的问题，您需要使用谓词。使用谓词，您可以创建包含相同组的字典组（数组）

试试下面的代码。

let array = [
    [
        "primary_dark_color": "#0d6d9f",
        "Groups": "A",
        "primary_color": "#03a9f4"
        ],
    [
        "primary_dark_color": "#0d6d9f",
        "Groups": "B",
        "primary_color": "#03a9f4"
        ],
    [
        "primary_dark_color": "#0d6d9f",
        "Groups": "A",
        "primary_color": "#03a9f4"
        ],
    [
        "primary_dark_color": "#0d6d9f",
        "Groups": "B",
        "primary_color": "#03a9f4"
        ]]

    var arrGroups = [String]()
    for dict in array 

        if !arrGroups.contains(dict["Groups"]!) 

            arrGroups.append(dict["Groups"]!)
        
    
    var arrTmp = [Array<Dictionary<String, String>>]()
    for i in 0..<arrGroups.count 

        var tmp:Array = array
        tmp = tmp.filter  ($0["Groups"]!).range(of: arrGroups[i], options: [.diacriticInsensitive, .caseInsensitive]) != nil 
        arrTmp.append(tmp)
    
    print(arrTmp)

arrTmp 中的每个数组都有包含相同组的字典

所以你的numberOfSections = arrTmp.count

还有numberOfRowsInSection = arrTmp[section].count

arrTmp 会有

[[["primary_color": "#03a9f4", "primary_dark_color": "#0d6d9f", "Groups": "A"], ["primary_color": "#03a9f4", "primary_dark_color": "#0d6d9f", "Groups": "A"]], [["primary_color": "#03a9f4", "primary_dark_color": "#0d6d9f", "Groups": "B"], ["primary_color": "#03a9f4", "primary_dark_color": "#0d6d9f", "Groups": "B"]]]

谢谢@Priya 你能告诉我数组值吗
