objective-c - 如何从我的应用程序中启动 Mail.app 中的新消息窗口

Question

我可以使用命令启动 Mail.app [[NSWorkspace sharedWorkspace] launchApplication:@"Mail.app"];

但我想在 Mail.app 中启动新消息窗口，而不是整个 Mail.app。我怎样才能这样做？

我得到了答案

 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];
