[SWIFT]앱에서 앱 실행하기

A App에서 B App 실행하면서 파라메터 전송하기

 

A App

// A App : 실행 시키는 앱
// testButton 버튼을 클릭하면 schemeUrl 전송

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }

    @IBAction func testButton(_ sender: UIButton) {
        if let schemeUrl = URL(string: "bapp://open?VC=testVC&color=purple&food=cake&birth=0716") {
            
            if UIApplication.shared.canOpenURL(schemeUrl) {
                if #available(iOS 10.0, *) {
                    UIApplication.shared.open(schemeUrl, completionHandler: { (success) in
                        if success {
                            print("The URL was delivered successfully.")
                        } else {
                            print("The URL failed to open")
                        }
                    })
                } else {
                    UIApplication.shared.openURL(schemeUrl as URL)
                }
            } else {
                print("Invalid URL specified.")
            }
        }
    }
 }

 

 

B App
