how to mutiple datamodel?-CodePudding

i have datamodel

struct DataModel: Hashable{
        var image:String
        var name:String
}
var model = [DataModel(image:"1",name:"2"),DataModel(image:"3",name:"4")]

i want to Multiply the element 3 time, is there any func can do it?

var model = [DataModel(image:"1",name:"2"),DataModel(image:"3",name:"4")，DataModel(image:"1",name:"2"),DataModel(image:"3",name:"4")，DataModel(image:"1",name:"2"),DataModel(image:"3",name:"4")]

CodePudding user response：

you could try this approach to Multiply your original model 3 times:

    let model = [DataModel(image:"1",name:"2"),DataModel(image:"3",name:"4")]
    var arr: [DataModel] = Array(repeating: model, count: 3).flatMap{$0}
    print("----> arr: \(arr)")

You can also do it using a simple for loop. You can easily modify inside this for loop according to your further needs.

let model = [DataModel(image:"1",name:"2"),DataModel(image:"3",name:"4")]
var newModelArray = [DataModel]()
        
for _ in 1...3 {
      newModelArray.append(model[0])
      newModelArray.append(model[1])
}
