如何从我的应用程序在 Mail.app 中启动新消息 window

Question

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

但我想在 Mail.app 而不是整个 Mail.app 中启动新消息 window。 我该怎么做？

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];
