ios 后台发送邮件之SKPSMTPMessage的使用

skpsmtpmessage 是ios第三方后台发送邮件库 https://github.com/jetseven/skpsmtpmessage.git

1、由于skpsmtpmessage是非ARC文件，所以要在 SKPSMTPMessage和 NSData+Base64Additions中添加

Your Target -> Get Info -> Build -> All Configurations -> Other Link Flags: -fno-objc-arc 标识

2、导入cfnetwork.frame框架

　　导入头文件#import "SKPSMTPMessage.h"  #import "NSData+Base64Additions.h"

　　SKPSMTPMessageDelegate协议，并实现两个协议方法

3、开始发送邮件

// 发送邮件
- (IBAction)sendEmail {
    
    SKPSMTPMessage *testSend = [[SKPSMTPMessage alloc]init];
    testSend.fromEmail = @"发送邮箱账号";
    testSend.toEmail = @"接收邮箱账号";
    testSend.relayHost = @"smtp.ym.163.com";
    testSend.requiresAuth = YES;
    testSend.login = @"发送邮箱账号";
    testSend.pass = @"发送邮箱密码";
    testSend.subject = [NSString stringWithCString:"测试" encoding:NSUTF8StringEncoding];
    // testSend.ccEmail = @"抄送人邮箱"; // 可不填
    testSend.wantsSecure = YES;
    testSend.delegate = self;
    
    NSDictionary *plainPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/plain; charset=UTF-8;
This is a test Email",kSKPSMTPPartContentTypeKey,
                               @"This is a test message.",kSKPSMTPPartMessageKey,@"8bit",kSKPSMTPPartContentTransferEncodingKey,nil];
   
    testSend.parts = [NSArray arrayWithObjects:plainPart, nil];
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        [testSend send];
    });
    
}

 // 回调方法

- (void)messageSent:(SKPSMTPMessage *)message
{
    NSLog(@"messageSuccessed-----%@", message);
}

- (void)messageFailed:(SKPSMTPMessage *)message error:(NSError *)error
{
    NSLog(@"messageFailed-----message - %@
error - %@", message, error);
}

 4、Tip：关于relayHost参数：smtp.ym.163.com（网易企业邮箱）smtp.163.com（网易邮箱）。具体其他邮箱服务器地址查看帮助中心。
