有没有人知道,通过官方SDK / Cocoa Touch,从iPhone发送短信是否可行,以及如何实现?

你可以展示MFMessageComposeViewController,它可以发送短信,但是有用户提示(他点击发送按钮)。没有用户许可,不可能这样做。在iOS 11上,你可以做扩展,就像传入消息的过滤器,告诉iOS它是不是垃圾邮件。没有什么是短信不能做的

下面是在iOS中发送短信的Swift版本代码。请注意,它只在实际设备中工作。在iOS 7+中测试的代码。你可以在这里阅读更多。

1)创建一个继承MFMessageComposeViewControllerDelegate和NSObject的新类:

import Foundation
import MessageUI

class MessageComposer: NSObject, MFMessageComposeViewControllerDelegate {
    // A wrapper function to indicate whether or not a text message can be sent from the user's device
    func canSendText() -> Bool {
        return MFMessageComposeViewController.canSendText()
    }

    // Configures and returns a MFMessageComposeViewController instance
    func configuredMessageComposeViewController(textMessageRecipients:[String] ,textBody body:String) -> MFMessageComposeViewController {
        let messageComposeVC = MFMessageComposeViewController()
        messageComposeVC.messageComposeDelegate = self  //  Make sure to set this property to self, so that the controller can be dismissed!
        messageComposeVC.recipients = textMessageRecipients
        messageComposeVC.body = body
        return messageComposeVC
    }

    // MFMessageComposeViewControllerDelegate callback - dismisses the view controller when the user is finished with it
    func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
        controller.dismissViewControllerAnimated(true, completion: nil)
        }
}

2)如何使用这个类:

func openMessageComposerHelper(sender:AnyObject ,withIndexPath indexPath: NSIndexPath) {
    var recipients = [String]()

    //modify your recipients here

    if (messageComposer.canSendText()) {
        println("can send text")
        // Obtain a configured MFMessageComposeViewController
        let body = Utility.createInvitationMessageText()

        let messageComposeVC = messageComposer.configuredMessageComposeViewController(recipients, textBody: body)

        // Present the configured MFMessageComposeViewController instance
        // Note that the dismissal of the VC will be handled by the messageComposer instance,
        // since it implements the appropriate delegate call-back
        presentViewController(messageComposeVC, animated: true, completion: nil)
    } else {
        // Let the user know if his/her device isn't able to send text messages
        self.displayAlerViewWithTitle("Cannot Send Text Message", andMessage: "Your device is not able to send text messages.")
    }
}

您可以使用sms:[目标电话号码]URL打开sms应用程序,但没有指示如何用文本预填充sms正文。

你可以使用这种方法:

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"sms:MobileNumber"]]

iOS会自动从你的应用程序导航到消息应用程序的消息合成页面。由于URL的方案是从sms:开始的,这被标识为消息应用程序可以识别的类型,并启动它。

如果您愿意,您可以使用名为CTMessageCenter类的私有框架CoreTelephony。有一些发送短信的方法。
