ios-发送邮件两种方式实现

代码的思路很清晰 比较简单
#import "ViewController.h"
//导入
#import <MessageUI/MessageUI.h>

@interface ViewController ()<MFMailComposeViewControllerDelegate>

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    //发邮件
#if 0
    //方法一：
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto:1143344@163.com"]];
#endif
    
    //方法二：
    //判断当前设置是否支持发送邮件
    if ([MFMailComposeViewController canSendMail])
    {
        MFMailComposeViewController *mailVC = [[MFMailComposeViewController alloc] init];
        //添加收件人
        [mailVC setToRecipients:@[@"1148828736@qq.com",@"test@163.com"]];
        //添加抄送人
        [mailVC setCcRecipients:@[@"1111@163.com"]];
        
        //添加"密送人"
        [mailVC setBccRecipients:@[@"22222@163.com"]];
        
        //添加主题
        [mailVC setSubject:@"百度招聘"];
        
        //添加邮件内容
       // [mailVC setMessageBody:@"<h1>该还钱了</h1><br><h4>该还钱了</h4>" isHTML:YES];
        [mailVC setMessageBody:@"哈哈哈哈哈哈" isHTML:NO];
        
        //添加附件
        [mailVC addAttachmentData:UIImagePNGRepresentation([UIImage imageNamed:@"Transfer_Refunded"]) mimeType:@"image/png" fileName:@"test.png"];
        
        //设置代理
        mailVC.mailComposeDelegate = self;
        
        [self presentViewController:mailVC animated:YES completion:nil];
    }
    else
    {
        NSLog(@"不支持发送邮件");
    }
    
}

    MFMailComposeResultSaved,      保存
    MFMailComposeResultSent,       发送成功
