macos - cocoa：从 Mail.app 读取邮件

Question

我想制作一个从 Mail.app 读取电子邮件并显示它们的 Mac 应用程序，但我找不到有关如何从 Mail.app 读取邮件的任何信息。我的问题是：

1. 如何从 Mail.app 阅读电子邮件？任何建议将不胜感激。

Answer 1

Applescript 可能是最简单的方法，例如：

tell application "Mail"
    set theMessage to message 1 of inbox
    set theBody to content of theMessage as rich text
end tell

运行脚本NSAppleScript，快速脏示例（无错误处理等）：

NSString *theSource = @"tell application \"Mail\"\n"
"set theMessage to message 4 of inbox\n"
"set theBody to content of theMessage as rich text\n"
"end tell\n"
"return theBody";
NSAppleScript* theScript = [[NSAppleScript alloc] initWithSource:theSource];
NSAppleEventDescriptor* theDescriptor = [theScript executeAndReturnError:NULL];
NSLog(@"%@", theDescriptor);

替代使用osascriptthroughNSTask来运行脚本。

遍历所有消息并将其正文添加到theMessages列表中。

set theMessages to {}
tell application "Mail"
    set theCount to get the count of messages of inbox
    repeat with theIncrementValue from 1 to theCount by 1
        set TheMessage to message 1 of inbox
        set theBody to content of TheMessage as rich text
        set end of theMessages to theBody
    end repeat
end tell
return theMessages
