備忘録

接続の仕方

Storyboard -> Segmented Control配置 -> Action接続でViewControllerに接続

コードでの記載内容

前提

LabelをStoryboardにOutlet接続 -> testLabel
Segmented ControlをAction接続 -> selectSegment

コード

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var testLabel: UILabel!
    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    @IBAction func selectSegment(_ sender: Any) {
        
        switch (sender as AnyObject).selectedSegmentIndex {
        case 0:
            testLabel.text = "こんにちは"
        case 1:
            testLabel.text = "ヤッホー"
        default:
            print("エラ〜")
        }
    }
}
