使用Swift在iOS中发送短信

问题描述

首先，我真的很惊讶这不是重复的，因为在Objective-C中有大量的堆栈溢出问题可以解决此问题，但是我还没有看到使用Swift的好答案.

First of all, I'm really surprised that this is not a duplicate, because there are TONS of stackoverflow questions that solve this in Objective-C, but I have yet to see a good answer that used Swift.

我正在寻找的是Swift中的代码段，该代码段将任意字符串作为文本消息的正文发送到给定的电话号码.从本质上讲，我想要苹果公司的此官方文档，但使用Swift而不是Objective-C.

What I'm looking for is a code snippet in Swift that sends an arbitrary string as a the body of a text message to given phone number. Essentially, I'd like something like this from Apple's official documentation, but in Swift instead of Objective-C.

我想这并不太困难，因为它可以在Android中只需几行代码即可完成.

I imagine this isn't too difficult, as it can be done in just a couple of lines of code in Android.

我要寻找的是5-20行Swift代码，我不同意它的范围太广.在Java(适用于Android)中，解决方案如下所示:

What I'm looking for is 5-20 lines of Swift code, I do not agree that this is too broad. In Java (for Android), the solution looks like this:

package com.company.appname;
import android.app.Activity;
import android.telephony.SmsManager;
public class MainActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        public static final mPhoneNumber = "1111111111";
        public static final mMessage = "hello phone";
        SmsManager.getDefault().sendTextMessage(mPhoneNumber, null, mMessage, null, null);
     }
}

现在这是android解决方案，它只有11行. Java往往比Swift更冗长，因此我怀疑我要问的是范围太广"，很可能我不知道如何使用Objective-C MessageComposer对象，因为我链接的文档关于Swift的用法，上面的内容尚不清楚.

Now this is the android solution, and it's only 11 lines. Java tends to be much more verbose than Swift, so I doubt what I'm asking is "too broad", it is more likely that I don't know how to use the Objective-C MessageComposer object, because the documentation that I linked to above is unclear with regard to usage in Swift.

推荐答案

不确定您是否真的找到了答案.我也遇到了类似的情况，遇到了这种解决方案，并使它起作用.

Not sure if you really got the answer. I was in a similar hunt and came across this solution and got it to work.

import UIKit
import MessageUI

class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {

    @IBOutlet weak var phoneNumber: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func sendText(sender: UIButton) {
        if (MFMessageComposeViewController.canSendText()) {
            let controller = MFMessageComposeViewController()
            controller.body = "Message Body"
            controller.recipients = [phoneNumber.text]
            controller.messageComposeDelegate = self
            self.presentViewController(controller, animated: true, completion: nil)
        }
    }

    func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
        //... handle sms screen actions
        self.dismissViewControllerAnimated(true, completion: nil)
    }

    override func viewWillDisappear(animated: Bool) {
        self.navigationController?.navigationBarHidden = false
    }
}
