XCode: No visibile @interface for (xxx) declares the selector (xxx)

Question

I'm trying to add functionality to add an attachment to an sms message. The following

if([MFMessageComposeViewController canSendAttachments]) {
    if(args[@"attachments"]) {
        NSString *attachmentData = [RCTConvert NSString:args[@"attachment"][@"data"]];
        NSString *typeIdentifier = @"kUTTypeJPEG";
        NSString *attchmentName = [RCTConvert NSString:args[@"attachment"][@"name"]];

        [mcvc addAttachmentData:attachmentData typeIdentifier:typeIdentifier fileName:attachmentName]
    }
}

throws this error:

No Visible @interface for 'MFMessageComposeViewController' declares the selector 'addAttachmentData:attachmentData typeIdentifier:typeIdentifier fileName:attachmentName'

This is why you always want to use Xcode's autocomplete. It avoid typos like this. — rmaddy, May 18 '16 at 15:46
I'm very new to all of this, so that tip is very much appreciated. — duwerq, May 18 '16 at 17:19

The correct name of the method is addAttachmentData:typeIdentifier:filename:.

See the lower case "n" in the last parameter label.

You have to use addAttachmentData:typeIdentifier:filename:
You have spelled your method wrong.
