推荐答案

MFMailComposeViewController 协议定义了所需的方法.使用方法

The MFMailComposeViewController protocol defines the method you need. Using the method

- (void)addAttachmentData:(NSData *)attachment mimeType:(NSString *)mimeType fileName:(NSString *)filename __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);

您可以轻松地将任何类型的文件添加为邮件的附件.最简单的方法是合并您存储在CSV字符串中的记录，并将数据存储在ass附件中.参见以下示例:

you can easily add any kind of file as an attachment to the mail. The easiest way would be to combine the records you stored in an CSV string and store data inside ass attachment. See below for an example:

MFMailComposeViewController *picker = [[[MFMailComposeViewController alloc] init] autorelease];
[picker setSubject:@"New Contacts"];
NSMutableString *body = [[NSMutableString alloc] init];
[body appendString:@"Hi, see attachment\n\n"];


NSMutableString *csv = [[NSMutableString alloc] init];
// Add data to csv
// ...

[picker addAttachmentData:[csv dataUsingEncoding:NSStringEncodingConversionExternalRepresentation allowLossyConversion:NO]
                 mimeType:@"text/csv"
                 fileName: @"contacts.csv"];
