iOS-调用系统的短信和发送邮件功能,实现短信分享和邮件分享

一、邮件分享

1、iOS系统自带邮件设置邮箱（此处以QQ邮箱为例）（http://jingyan.baidu.com/album/6181c3e084cb7d152ef153b5.html?picindex=1）

　　注意：由于QQ邮箱激活时间不满14天，暂时无法设置POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务

　　　　　会造成只能发送邮件，但是邮件接收不到的情况。

2、实现功能

- (void)displayMailComposerSheet
{
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    
    // 设置picker的委托方法，完成之后会自动调用成功或失败的方法
    picker.mailComposeDelegate = self;
    // 添加主题
    [picker setSubject:@"文件分享"];
    // 添加收件人
    //NSArray *toRecipients = [NSArray arrayWithObject:@"收件人@qq.com"];
    // 说明：也可以添加多个收件人，代码如下所示：
//    NSArray *toRecipients = [NSArray arrayWithObjects:@"one@qq.com",@"two@qq.com",nil];
    // 添加抄送
//    NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@qq.com",@"third@qq.com", nil];
    // 添加密送
//    NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@qq.com"];
    
    [picker setToRecipients:toRecipients];
//    [picker setCcRecipients:ccRecipients];
//    [picker setBccRecipients:bccRecipients];
    
    // 直接在HTML代码中写入图片的地址
    NSString *emailBody = [NSString stringWithFormat:@"<img src='http://p2.so.qhimg.com/t0130e3288d86929b97.jpg' /><p>我分享了图片</p>"];
    
    [picker setMessageBody:emailBody isHTML:YES];
    [self presentModalViewController:picker animated:YES];
    [picker release];
}

这样实现的效果是，在邮件中会显示一个图片和一段文本，关键是第25行代码，一定要设置isHTML为YES。但实际应用中，图片一般我们没有上传到服务器上，而是在客户端，这时候我们可以用下面的方式来发送图片(将第23行代码替换成下面的代码)：

// 发送图片附件(其他格式的附件，可以都先转化称NSData类型，然后设置相应的mimeType即可，如txt类型为@"text/txt",doc类型为@"text/doc",pdf类型为@"file/pdf"等等)
    NSData *myData = [NSData dataWithContentsOfFile:[[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:@"new.png"]];
    [picker addAttachmentData:myData mimeType:@"image/jpeg" fileName:@"new.png"];
    NSString *emailBody = [NSString stringWithFormat:@"<p>我分享了图片</p>"];

使用上面这种方式，将isHTML设置为YES的话，图片会显示在正文中；isHTML设置为NO的话，图片会显示在附件中。

》添加邮箱附件方法：

//发送图片附件
//NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"jpg"];
//NSData *myData = [NSData dataWithContentsOfFile:path];
//[picker addAttachmentData:myData mimeType:@"image/jpeg" fileName:@"rainy.jpg"];
//发送txt文本附件
//NSString *path = [[NSBundle mainBundle] pathForResource:@"MyText" ofType:@"txt"];
//NSData *myData = [NSData dataWithContentsOfFile:path];
//[picker addAttachmentData:myData mimeType:@"text/txt" fileName:@"MyText.txt"];
//发送doc文本附件 
//NSString *path = [[NSBundle mainBundle] pathForResource:@"MyText" ofType:@"doc"];
//NSData *myData = [NSData dataWithContentsOfFile:path];
//[picker addAttachmentData:myData mimeType:@"text/doc" fileName:@"MyText.doc"];
//发送pdf文档附件
/*
NSString *path = [[NSBundlemainBundle]pathForResource:@"CodeSigningGuide"ofType:@"pdf"];
NSData *myData = [NSDatadataWithContentsOfFile:path];
[pickeraddAttachmentData:myDatamimeType:@"file/pdf"fileName:@"rainy.pdf"];
*/

邮件发送完成之后，可以在如下的委托方法中进行相应的处理，委托方法如下所示：

- (void)mailComposeController:(MFMailComposeViewController*)controller
          didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
    switch (result)
    {
        case MFMailComposeResultCancelled:
            NSLog(@"Result: Mail sending canceled");  // 邮件发送取消  
            break;
        case MFMailComposeResultSaved:
            NSLog(@"Result: Mail saved");  // 邮件保存成功
            break;
        case MFMailComposeResultSent:
            NSLog(@"Result: Mail sent");  // 邮件发送成功
            break;
        case MFMailComposeResultFailed:
            NSLog(@"Result: Mail sending failed");  // 邮件发送失败
            break;
        default:
            NSLog(@"Result: Mail not sent");
            break;
    }
    [self dismissModalViewControllerAnimated:YES];
}

导入MessageUI.framework

.h文件中#import<MessageUI/MessageUI.h>

#import<MessageUI/MFMailComposeViewController.h>

实现 MFMailComposeViewControllerDelegate, MFMessageComposeViewControllerDelegate

二、发送短信

//短信
-(void)showSMSPicker{
   Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));

    if (messageClass != nil) { 
   // Check whether the current device is configured for sending SMS messages
        if ([messageClass canSendText]) {
        [selfdisplaySMSComposerSheet];
        }
        else { 
            UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@""message:@"设备不支持短信功能" delegate:selfcancelButtonTitle:@"确定" otherButtonTitles:nil];
            [alert show];
            [alert release];
            
        }
    }
    else {
        }
 }

-(void)displaySMSComposerSheet
{
   MFMessageComposeViewController *picker = [[MFMessageComposeViewControlleralloc]init];
picker.messageComposeDelegate =self;
NSString *smsBody =[NSStringstringWithFormat:@"我分享了文件给您，地址是%@",address] ;
    picker.body=smsBody;
[selfpresentModalViewController:pickeranimated:YES];
[pickerrelease];
}
