IOS 调发短信和邮件界面

苹果官方demo下载地址：https://developer.apple.com/library/ios/samplecode/MessageComposer/Introduction/Intro.html

发短信比较简单：

1.首先倒入系统库：MessageUI.framework  CoreGraphics.framework

2.  实现代理  

    MFMailComposeViewControllerDelegate,    －－－－发邮件

    MFMessageComposeViewControllerDelegate,－－－发短信

    UINavigationControllerDelegate

3. 实现：（包括发短信和发邮件）

以下代码为官方的demo中的demo

#pragma mark - Compose Mail/SMS

// -------------------------------------------------------------------------------
//displayMailComposerSheet
//  Displays an email composition interface inside the application.
//  Populates all the Mail fields.
// -------------------------------------------------------------------------------
- (void)displayMailComposerSheet 
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;

[picker setSubject:@"Hello from California!"];

// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObject:@"[e-mail]"]; 
NSArray *ccRecipients = [NSArray arrayWithObjects:@"[e-mail]", @"[e-mail]", nil]; 
NSArray *bccRecipients = [NSArray arrayWithObject:@"[e-mail]"]; 

[picker setToRecipients:toRecipients];
[picker setCcRecipients:ccRecipients];
[picker setBccRecipients:bccRecipients];

// Attach an image to the email
NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"jpg"];
NSData *myData = [NSData dataWithContentsOfFile:path];
[picker addAttachmentData:myData mimeType:@"image/jpeg" fileName:@"rainy"];

// Fill out the email body text
NSString *emailBody = @"It is raining in sunny California!";
[picker setMessageBody:emailBody isHTML:NO];

[self presentViewController:picker animated:YES completion:NULL];
}

// -------------------------------------------------------------------------------
//displayMailComposerSheet
//  Displays an SMS composition interface inside the application.
// -------------------------------------------------------------------------------
- (void)displaySMSComposerSheet 
{
MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
picker.messageComposeDelegate = self;

    // You can specify one or more preconfigured recipients.  The user has
    // the option to remove or add recipients from the message composer view
    // controller.
   <span style="color:#ff0000;"> /* picker.recipients = @[@"Phone number here"]; */     此处可以填写需要发送的手机号码</span>

    // You can specify the initial message text that will appear in the message
    // composer view controller.
   <span style="color:#ff0000;"> picker.body = @"Hello from California!";   短信内容</span>
   <span style="color:#ff0000;"> 打开短信界面时，就会看到短信内容和手机号码自动填充好了。</span>
    [self presentViewController:picker animated:YES completion:NULL];
}
