Can I set document or excel file in mailcomposer in iphone application.

If anyone know please help me.

Thanks alot.

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);

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"];
