使用iOS开源库SKPSMTPMessage实现邮件发送

iOS下发邮件目前有两种方式，利用openURL打开iOS email app和利用MFMailComposeViewController在app内弹出email界面实现邮件发送。这两种方式搜索一下都有很多介绍，具体就不细说了。下面介绍第三种方式，利用开源库SKPSMTPMessage实现邮件发送。其实这种方式也有不少文章介绍了，只是看了一些文章，写得都差不多，都是贴demo里面的代码，没有我需要的发送图片和视频附件的功能。研究和查阅了一些资料，将代码综合一下，粘贴出来方便自己和有需要的人查阅。

发送邮件，包含附件代码如下：

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

SKPSMTPMessage *testMsg = [[SKPSMTPMessage alloc] init];
testMsg.fromEmail = [defaults objectForKey:@"fromEmail"];

testMsg.toEmail = [defaults objectForKey:@"toEmail"];
testMsg.bccEmail = [defaults objectForKey:@"bccEmal"];
testMsg.relayHost = [defaults objectForKey:@"relayHost"];

testMsg.requiresAuth = [[defaults objectForKey:@"requiresAuth"] boolValue];

if (testMsg.requiresAuth) {
testMsg.login = [defaults objectForKey:@"login"];

testMsg.pass = [defaults objectForKey:@"pass"];

}

testMsg.wantsSecure = [[defaults objectForKey:@"wantsSecure"] boolValue]; // smtp.gmail.com doesn't work without TLS!

testMsg.subject = @"SMTPMessage Test Message";
//testMsg.bccEmail = @"testbcc@test.com";

// Only do this for self-signed certs!
// testMsg.validateSSLChain = NO;
testMsg.delegate = self;

//文字信息
NSDictionary *plainPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/plain",kSKPSMTPPartContentTypeKey,
@"This is a tést messåge.",kSKPSMTPPartMessageKey,@"8bit",kSKPSMTPPartContentTransferEncodingKey,nil];
//联系人信息
NSString *vcfPath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"vcf"];
NSData *vcfData = [NSData dataWithContentsOfFile:vcfPath];

NSDictionary *vcfPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/directory;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.vcf\"",kSKPSMTPPartContentTypeKey,
@"attachment;\r\n\tfilename=\"test.vcf\"",kSKPSMTPPartContentDispositionKey,[vcfData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];
//图片和视频附件
//attach image
NSString *imgPath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"jpg"];
NSData *imgData = [NSData dataWithContentsOfFile:imgPath];
NSDictionary *imagePart = [NSDictionary dictionaryWithObjectsAndKeys:@"image/jpg;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.jpg\"",kSKPSMTPPartContentTypeKey,
@"attachment;\r\n\tfilename=\"test.jpg\"",kSKPSMTPPartContentDispositionKey,[imgData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];

//attach video
NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"video" ofType:@"mov"];
NSData *videoData = [NSData dataWithContentsOfFile: videoPath];
NSDictionary *videoPart = [NSDictionary dictionaryWithObjectsAndKeys:@"video/quicktime;\r\n\tx-unix-mode=0644;\r\n\tname=\"video.mov\"",kSKPSMTPPartContentTypeKey,
@"attachment;\r\n\tfilename=\"video.mov\"",kSKPSMTPPartContentDispositionKey,[videoData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];

testMsg.parts = [NSArray arrayWithObjects:plainPart,vcfPart, imagePart, videoPart, nil];

[testMsg send];

代码是在Demo基础上修改，经过测试，可以正常发送带附件的email。
