iOS中发送短信/发送邮件的实现 韩俊强的博客

需要引入框架:
MessageUI.framework

布局如下:



短信和邮件:

#import "ViewController.h"
#import <MessageUI/MessageUI.h>

@interface ViewController ()<MFMessageComposeViewControllerDelegate,MFMailComposeViewControllerDelegate>//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];
[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:%@",@"13683799303@163.com"]];
//cc:抄送对象  subject:主题  body:内容
//NSURL *mailURL2 = [NSURL URLWithString:[NSString stringWithFormat:@"mailto:%@?cc = %@&subject = %@&body = %@",@"13683799303@163.com",@"13683799303@26.com",@"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:@[@"13683799303@163.com",@"135895587@qq.com"]];

//设置抄送对象,
[mailVC setCcRecipients:@[@"13683799303@163.com",@"135895587@qq.com"]];

//设置密送
[mailVC setBccRecipients:@[@"13683799303@163.com"]];

//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];
[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)
