iOS中发送短信/发送邮件的实现

版权声明：本文为博主原创文章，未经博主允许不得转载。

需要引入框架:

MessageUI.framework

布局如下:

短信和邮件:

#import "ViewController.h"
#import

@interface ViewController ()//遵循协议

@end

@implementation ViewController

短信功能:

//短信功能
- (IBAction)messageButtonAction:(UIButton *)sender {
#pragma mark 程序外发送短信

    /*
    //定义打开短信的url, 关键字: sms:
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"sms://%@",@"10086"]];
    //判断程序是否可以调用打开短信功能
    if ([[UIApplication sharedApplication] canOpenURL:url]) {
        [[UIApplication sharedApplication] openURL:url];
    }else{
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"提示" message:@"您的设备不支持此短信功能" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
        [alert show];
    }
     */
/*
 用openURL来打开程序中的短信功能, 需要用到关键字: "sms:", 后面加上要发送的电话就可以了;
 缺点:1.这个方法会跳出我们正在运行的程序,打开系统的短信界面, 但当用户关闭短信后, 无法回到程序.
     2.这个方法我们只能定义要发送的手机号, 无法编辑发送的短信内容;

 */
    }

#pragma mark 程序内发送短信

    /*

     为了弥补上述的两个方法的不足,需要另一种使用短信功能的方法:程序内使用短信功能.

     */

    

    //1.添加短信所需要的框架: MessageUI.framework

    //2.引入头文件,实现如下代码

    //3.判断是否可以发短信

- (IBAction)messageButtonAction:(UIButton *)sender {
#pragma mark 程序外发送短信
  BOOL canSendMessage = [MFMessageComposeViewController canSendText];
    if (canSendMessage) {
        //创建短信视图控制器
        MFMessageComposeViewController *messageVC = [[MFMessageComposeViewController alloc]init];
        //设置代理
        messageVC.messageComposeDelegate = self;

        //设置短信内容
        messageVC.body = @"来一条信息";

        //设置电话, 是一个数组, 可以设置多个电话, 实现群发功能
        messageVC.recipients = @[@"10086",@"10010"];

        //打开短信功能, 通过这个方法会在程序内打开一个短信界面;

        [self presentViewController:messageVC animated:YES completion:nil];

    }else{
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"提示" message:@"您的设备不支持此短信功能" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil nil];
        [alert show];
    }


}

信息的代理方法:

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{

    //MessageComposeResult 的枚举值:
//    MessageComposeResultCancelled, //取消发送短信功能
//    MessageComposeResultSent,     //发送短信
//    MessageComposeResultFailed    //发送失败
    if (result == MessageComposeResultCancelled || result == MessageComposeResultSent) {
        [self dismissViewControllerAnimated:YES completion:nil];
    }

}

邮件功能:

//邮件功能
- (IBAction)mailButtonAction:(UIButton *)sender {
#pragma mark 程序外发送邮件

    /*
    //打开系统邮件页面, mailto:
    NSURL *mailURL = [NSURL URLWithString:[NSString stringWithFormat:@"mailto:%@",@"[email protected]"]];
    //cc:抄送对象  subject:主题  body:内容
    //NSURL *mailURL2 = [NSURL URLWithString:[NSString stringWithFormat:@"mailto:%@?cc = %@&subject = %@&body = %@",@"[email protected]",@"[email protected]",@"邮件",@"你好啊!"]];

    if ([[UIApplication sharedApplication] canOpenURL:mailURL]) {
        [[UIApplication sharedApplication] openURL:mailURL];
    }else{

        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"提示" message:@"您的设备不支持邮件功能" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
        [alert show];

    }
     */
    /*
     此方法来发送邮件同上述短信一样,也会跳出程序,调用系统的邮件界面;
     */

#pragma mark 程序内发送邮件

    //判断是否可以发送邮件
    BOOL canSendMail = [MFMailComposeViewController canSendMail];
    if (canSendMail) {
        //创建邮件视图控制器
        MFMailComposeViewController *mailVC = [[MFMailComposeViewController alloc]init];
        //设置接收邮件人, 数组,可以实现群发
        [mailVC setToRecipients:@[@"[email protected]",@"[email protected]"]];

        //设置抄送对象,
        [mailVC setCcRecipients:@[@"[email protected]",@"[email protected]"]];

        //设置密送
        [mailVC setBccRecipients:@[@"[email protected]"]];

        //设置内容
        [mailVC setMessageBody:@"很高兴认识你" isHTML:NO];

        //设置代理
        mailVC.mailComposeDelegate = self;
        //打开邮件功能
        [self presentViewController:mailVC animated:YES completion:nil];
    }else{
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"提示" message:@"您的设备不支持邮件功能" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil nil];
        [alert show];

    }


}

邮件代理的方法:

- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
    //    MFMailComposeResultCancelled,  取消发送
    //    MFMailComposeResultSaved,      保存
    //    MFMailComposeResultSent,       发送
    //    MFMailComposeResultFailed      发送失败

    switch (result) {
        case MFMailComposeResultCancelled:
            NSLog(@"取消发送");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"保存");
            break;
        case MFMailComposeResultSent:
            NSLog(@"发送成功");
            break;
        case MFMailComposeResultFailed:
            NSLog(@"失败");
            break;

        default:
            break;
    }

    [self dismissViewControllerAnimated:YES completion:nil];

}

最终效果:(由于模拟器没法演示发送短信,所以会出现下面的现象)
