skpsmtpmessage 是ios第三方后台发送邮件库

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;\nThis 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 - %@\nerror - %@", 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。
