Locking the Fields in MFMailComposeViewController

Answer 1

您可以使用此叉SKSMTPMessage的：https://github.com/jetseven/skpsmtpmessage

存在與文件發送電子郵件示範項目，查看本源文件：https://github.com/jetseven/skpsmtpmessage/blob/master/Demo/Classes/SMTPSenderAppDelegate.m

你需要這些行：

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]; 

哪裏testMsg是SKPSMTPMessage類

如果我這樣做，它會附上PDF文件和PNG文件，以信的實例？

的NSDictionary * plainPart = [NSDictionary的dictionaryWithObjectsAndKeys：@ 「文本/純」，kSKPSMTPPartContentTypeKey， @ 「這是一個測試消息。」，kSKPSMTPPartMessageKey，@ 「8位」，kSKPSMTPPartContentTransferEncodingKey，零]。

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];

我剛剛發現了另一個庫發送iOS上的電子郵件：MailCore

有添加附件的電子郵件的特殊類：CTCoreAttachment
