不斷收到http傳輸安全錯誤，即使我已經添加了代碼來繞過安全

Question

我已經嘗試了不同方法的加載，通常我使用的代碼工作。然而在這種情況下，我不確定它是否與我使用的教程中的代碼有關。他們使用https而不是http。我已經嘗試過不同的方法，我不知道該怎麼做！任何意見，將不勝感激。

@IBAction func signinTapped(sender : UIButton) { 
    let username:NSString = txtUsername.text! 
    let password:NSString = txtPassword.text! 

    if (username.isEqualToString("") || password.isEqualToString("")) { 

     let alertView:UIAlertView = UIAlertView() 
     alertView.title = "Sign in Failed!" 
     alertView.message = "Please enter Username and Password" 
     alertView.delegate = self 
     alertView.addButtonWithTitle("OK") 
     alertView.show()

     NSLog("PostData: %@",post); 
      let url = NSURL(string:"http://") 

     let postData:NSData = post.dataUsingEncoding(NSASCIIStringEncoding)! 

     let postLength:NSString = String(postData.length) 

     let request:NSMutableURLRequest = NSMutableURLRequest(URL: url!)

func textFieldShouldReturn(textField: UITextField) -> Bool { //delegate method 
    textField.resignFirstResponder() 
    return true 
}

我建議環境變量設置CFNETWORK_DIAGNOSTICS 3，運行你的應用程序，看到它記錄了什麼錯誤。這應該給你一些關於發生了什麼問題的跡象。

可能性是，您的ATS異常以某種微妙的方式出錯。
