objective-c - 从带有附件和主题的外部应用程序打开 Mail.app

Question

我想打开 Mail.app 并指定要附加的主题和文件。我可以独立做任何一个，但不能同时做。

要设置主题，我可以形成一个 mailto: string 和 NSWorkspace openURL。

要设置我可以使用的附件

[[NSWorkspace sharedWorkspace] openFile:resolvedPath withApplication:@"Mail"];

我不知道适用于 Mac 的 iOS 的 MFMailComposeViewController 等效项。我有哪些选择？

Answer 1

NSString* subject = @"mail subject";
NSString* body = @"mail body";
NSString* to = @"recipient@example.org";

NSString *encodedSubject = [NSString stringWithFormat:@"SUBJECT=%@", [subject stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *encodedBody = [NSString stringWithFormat:@"BODY=%@", [body stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *encodedTo = [to stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *encodedURLString = [NSString stringWithFormat:@"mailto:%@?%@&%@", encodedTo, encodedSubject, encodedBody];
NSURL *mailtoURL = [NSURL URLWithString:encodedURLString];

[[NSWorkspace sharedWorkspace] openURL:mailtoURL];
