Ios 是否将文件添加到MFMailComposeViewController中的传出邮件？

如何使用smtp发件人向邮件添加文件示例如下：

您可以使用此SKSMTPMessage分支：

有一个演示项目可以发送包含文件的电子邮件，请查看此源文件：

您需要这些行：

NSDictionary *plainPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/plain",kSKPSMTPPartContentTypeKey,
                               @"This is a tést messåge.",kSKPSMTPPartMessageKey,@"8bit",kSKPSMTPPartContentTransferEncodingKey,nil];

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];

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

其中testMsg是

SKPSMTPMessage

class

的一个实例，如果我这样做，它会将pdf文件和PNG文件附加到信函中

NSDictionary*plainPart=[NSDictionary Dictionary WithObjectsAndKeys:@“text/plain”，kSKPSMTPPartContentTypeKey， @“这真是一团糟。”，kSKPSMTPPartMessageKey，@“8位”，kskpsmtppartcontenttransferencodkey，nil]

NSString *vcfPath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"];
NSData *vcfData = [NSData dataWithContentsOfFile:vcfPath];

NSDictionary *vcfPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/directory;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.pdf\"",kSKPSMTPPartContentTypeKey,
                         @"attachment;\r\n\tfilename=\"test.pdf\"",kSKPSMTPPartContentDispositionKey,[vcfData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];
NSString *vcfPath1 = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"png"];
NSData *vcfData1 = [NSData dataWithContentsOfFile:vcfPath1];

NSDictionary *vcfPart1 = [NSDictionary dictionaryWithObjectsAndKeys:@"text/directory;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.png\"",kSKPSMTPPartContentTypeKey,
                         @"attachment;\r\n\tfilename=\"test.png\"",kSKPSMTPPartContentDispositionKey,[vcfData1 encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];
testMsg.parts = [NSArray arrayWithObjects:plainPart,vcfPart,vcfPart1,nil];

我刚刚找到另一个用于在iOS上发送电子邮件的库：

有一个专门为电子邮件添加附件的课程：

非常感谢，这就是我需要的！
