调用手机内部邮件发送邮件，首先要对邮件进行设置，确定可以发送邮件后才可以，否则邮件无法正常发送。
（一） 头文件
#import <UIKit/UIKit.h> #import <MessageUI/MessageUI.h> #import "MailViewController.h" @interface MailViewController ()<MFMailComposeViewControllerDelegate> { UILabel *sendResult; } @end
（二）发送邮件
-(void)sendMail { if ([MFMailComposeViewController canSendMail]) { NSLog(@"canSend:YES"); sendResult.text=@"canSend:Yes"; // 创建邮件发送界面 MFMailComposeViewController *mailCompose = [[MFMailComposeViewController alloc] init]; // 设置邮件代理 [mailCompose setMailComposeDelegate:self]; // 设置收件人 [mailCompose setToRecipients:@[@"liuliangchb@163.com"]]; // 设置抄送人 [mailCompose setCcRecipients:@[@"807243674@qq.com"]]; // 设置密送人 [mailCompose setBccRecipients:@[@"15690725786@163.com"]]; // 设置邮件主题 [mailCompose setSubject:@"Test"]; //设置邮件的正文内容 NSString *emailContent = @"Test mail"; // 是否为HTML格式 [mailCompose setMessageBody:emailContent isHTML:NO]; // 如使用HTML格式，则为以下代码 // [mailCompose setMessageBody:@"<html><body><p>Hello</p><p>World！</p></body></html>" isHTML:YES]; //添加附件 /* UIImage *image = [UIImage imageNamed:@"imageName"];//添加图片附件 NSData *imageData = UIImagePNGRepresentation(image); [mailCompose addAttachmentData:imageData mimeType:@"" fileName:@"imageName.png"];
NSString *file = [[NSBundle mainBundle] pathForResource:@"pdfFile" ofType:@"pdf"];//添加子文件路径 NSData *pdf = [NSData dataWithContentsOfFile:file]; [mailCompose addAttachmentData:pdf mimeType:@"" fileName:@"pdfFile.pdf"];
NSString *file = [[NSString alloc] initWithString:filePath];//通过全路径filePath添加文件附件
NSData *pdf = [NSData dataWithContentsOfFile:file];
[mailView addAttachmentData:pdf mimeType:@"" fileName:[[NSString alloc] initWithString:fileName]]; */ // 弹出邮件发送视图 [self presentViewController:mailCompose animated:YES completion:nil]; } else { NSLog(@"canSend:NO"); sendResult.text=@"canSend:No"; } }
（三）通过代理获取发送结果
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{ switch (result) { case MFMailComposeResultCancelled: sendResult.text=@"Canceled"; break; case MFMailComposeResultSaved: sendResult.text=@"Saved"; break; case MFMailComposeResultSent: sendResult.text=@"Sent"; break; case MFMailComposeResultFailed: sendResult.text=@"Failed"; break; } // 关闭邮件发送视图 [self dismissViewControllerAnimated:YES completion:nil]; }
