Sort Table view from API-CodePudding

in swift UIKit

I am trying to arrange the data in Table View according to the string variable from API

But it gives me an error

 var arrTable = [ModelApiData]()

    override func viewDidLoad() {
            super.viewDidLoad()
            
            for i in arrTable {
             
                arrTable.sorted(by: i.url)
            }
            arrTable.sorted(by: ModelApiData)
    }

name (url) I want to arrange the cells on it

{
    "id": 130,
    "user_id": 1,
    "title": "test Sort 2",
    "details": "ESFFESFSD",
    "image_path": null,
    "youtube_link": null,
    "font_size": 19,
    "algiment": "right",
    "color": "0 0 0 1",
    "url": "2",
    "category_id": 2
},

error is

Cannot convert value of type 'String?' to expected argument type '(ModelApiData, ModelApiData) throws -> Bool'

Also, if I use this method, I cannot determine from API

arrTable.sorted(by: ModelApiData)

CodePudding user response：

Your code makes not sense for several reasons:

The error tells you that you cannot sort just by passing the type. You have to specify one or multiple properties and apply the < operator.
sorted returns the sorted array, it does not sort in place.
Sorting in a loop is pointless.

To sort the array by the url property you have to write

override func viewDidLoad() {
    super.viewDidLoad()

    arrTable.sort(by: {$0.url < $1.url})
}

Side note: Avoid optionals as much as possible.

CodePudding user response：

 arrTable.sorted(by: {$0.url > $1.url})

chose your own ascending or descending sorting way

arrTable.sorted(by: {$0.url > $1.url})

i ll suggest u to make func of sorting

func sortingData(array:[ModelApiData]) -> [ModelApiData] {
   return array.sorted(by: {$0.url > $1.url})
}

then use it to number of item in section and

sortingData(array:arrTable).count

and in cell for row at

let data = sortingData(array:arrTable)[indexPath].row
cell.textLabel.text = data.title
