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?

- (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
UIImage *ui =resultimg.image;
pasteboard.image = ui;
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms:"]];
}

如果你想在你自己的应用程序中显示创建和发送消息,你需要使用MFMessageComposeViewController。
否则,您可以使用sharedApplication方法。
用这个:
- (void)showSMSPicker
{
Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));
if (messageClass != nil) {
// Check whether the current device is configured for sending SMS messages
if ([messageClass canSendText]) {
[self displaySMSComposerSheet];
}
}
}
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
//feedbackMsg.hidden = NO;
// Notifies users about errors associated with the interface
switch (result)
{
case MessageComposeResultCancelled:
{
UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"SMS sending canceled!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
[alert1 show];
[alert1 release];
}
// feedbackMsg.text = @"Result: SMS sending canceled";
break;
case MessageComposeResultSent:
{
UIAlertView *alert2 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"SMS sent!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
[alert2 show];
[alert2 release];
}
// feedbackMsg.text = @"Result: SMS sent";
break;
case MessageComposeResultFailed:
{
UIAlertView *alert3 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"SMS sending failed!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
[alert3 show];
[alert3 release];
}
// feedbackMsg.text = @"Result: SMS sending failed";
break;
default:
{
UIAlertView *alert4 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"SMS not sent!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
[alert4 show];
[alert4 release];
}
// feedbackMsg.text = @"Result: SMS not sent";
break;
}
[self dismissModalViewControllerAnimated: YES];
}
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
