使用iOS开源库SKPSMTPMessage实现邮件发送

http://blog.csdn.net/aldridge1/article/details/18766515

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：

[cpp] view plaincopy

1. NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
3. SKPSMTPMessage *testMsg = [[SKPSMTPMessage alloc] init];
4. testMsg.fromEmail = [defaults objectForKey:@"fromEmail"];
6. testMsg.toEmail = [defaults objectForKey:@"toEmail"];
7. testMsg.bccEmail = [defaults objectForKey:@"bccEmal"];
8. testMsg.relayHost = [defaults objectForKey:@"relayHost"];
10. testMsg.requiresAuth = [[defaults objectForKey:@"requiresAuth"] boolValue];
12. if (testMsg.requiresAuth) {
13. testMsg.login = [defaults objectForKey:@"login"];
15. testMsg.pass = [defaults objectForKey:@"pass"];
17. }
19. testMsg.wantsSecure = [[defaults objectForKey:@"wantsSecure"] boolValue]; // smtp.gmail.com doesn't work without TLS!
22. testMsg.subject = @"SMTPMessage Test Message";
23. //testMsg.bccEmail = @"testbcc@test.com";
25. // Only do this for self-signed certs!
26. // testMsg.validateSSLChain = NO;
27. testMsg.delegate = self;
29. //文字信息
30. NSDictionary *plainPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/plain",kSKPSMTPPartContentTypeKey,
31. @"This is a tést messåge.",kSKPSMTPPartMessageKey,@"8bit",kSKPSMTPPartContentTransferEncodingKey,nil];
32. //联系人信息
33. NSString *vcfPath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"vcf"];
34. NSData *vcfData = [NSData dataWithContentsOfFile:vcfPath];
36. NSDictionary *vcfPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/directory;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.vcf\"",kSKPSMTPPartContentTypeKey,
37. @"attachment;\r\n\tfilename=\"test.vcf\"",kSKPSMTPPartContentDispositionKey,[vcfData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];
38. //图片和视频附件
39. //attach image
40. NSString *imgPath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"jpg"];
41. NSData *imgData = [NSData dataWithContentsOfFile:imgPath];
42. NSDictionary *imagePart = [NSDictionary dictionaryWithObjectsAndKeys:@"image/jpg;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.jpg\"",kSKPSMTPPartContentTypeKey,
43. @"attachment;\r\n\tfilename=\"test.jpg\"",kSKPSMTPPartContentDispositionKey,[imgData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];
45. //attach video
46. NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"video" ofType:@"mov"];
47. NSData *videoData = [NSData dataWithContentsOfFile: videoPath];
48. NSDictionary *videoPart = [NSDictionary dictionaryWithObjectsAndKeys:@"video/quicktime;\r\n\tx-unix-mode=0644;\r\n\tname=\"video.mov\"",kSKPSMTPPartContentTypeKey,
49. @"attachment;\r\n\tfilename=\"video.mov\"",kSKPSMTPPartContentDispositionKey,[videoData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];
51. testMsg.parts = [NSArray arrayWithObjects:plainPart,vcfPart, imagePart, videoPart, nil];
53. [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。
