我試圖發送一個短信,並使用該代碼的短信錯誤:雨燕3.0:發送
import UIKit
import MessageUI
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
@IBAction func sendMessage(_ sender: UIButton) {
let messageVC = MFMessageComposeViewController()
messageVC.body = "For a good time call!"
messageVC.recipients = ["79161887060"]
messageVC.messageComposeDelegate = self
self.present(messageVC, animated: true, completion: nil)
}
}
extension ViewController: MFMessageComposeViewControllerDelegate {
func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
switch (result.rawValue) {
case MessageComposeResult.cancelled.rawValue:
print("Message was cancelled")
self.dismiss(animated: true, completion: nil)
case MessageComposeResult.failed.rawValue:
print("Message failed")
self.dismiss(animated: true, completion: nil)
case MessageComposeResult.sent.rawValue:
print("Message was sent")
self.dismiss(animated: true, completion: nil)
default:
break;
}
}
}
構建成功,但是當我輕點按鈕(動作發送短信) - 調試器去的appdelegate文件並停止在那裏:

請幫助解決該問題。有任何想法嗎?
也許這個問題,因爲我在模擬器上運行腳本,而不是在設備上?
在此先感謝!
我的第一個建議是檢查它是否在設備上工作。錯誤是:應用程序試圖在目標上呈現一個零模式視圖控制器。看來messageVC是無效的或者無法呈現。可能由於模擬器? – Darkwonder
謝謝。我試圖做到這一點 –
