如何使用来自另一个视图控制器的用户输入来使用表视图单元格创建列表

Question

I'm making an iOS app with Swift that has two scenes. One asks for user input and that is saved in an array. I'm trying to make a list with table view cells in the other scene, and that list includes the user input that is saved when the user clicks on the save button.

tried creating a sharedData class in a separate file, tried this:

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if (segue.identifier == "segueTest") {
        var svc = segue!.destinationViewController as! goalViewController
        svc.toPass = textInput
    }
}

(both from other stackoverflow questions)

Answer 1

尝试将数组保存到NSUserDefaults中，然后在新视图中调用保存在NSUserDefaults中的对象。

Answer 2

- Using Delegate is one of the preferred way

Example:

protocol PExposeArrayDelegate: class
{
   func getArrayOfItems(array: String)
}


class CustomArray
{

// delegate property to expose array to the view-controller
    internal weak var delegateForTimeLineCell: PExposeArrayDelegate?


internal func createArray()
{
    let arr = ["Vivek","India","Audi"]

     delegateForTimeLineCell.getArrayOfItems(array: arr)
}

}

Now in the class where you want to access the array, do the following:

- Conform to protocol (Delegate) defined above

- Assign self to the delegate

- Implement the delegate method and then access the array from inside it.
