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

通过NSAppleScript运行脚本，快速脏示例(没有错误处理等):

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);

或者使用 osascript 通过 NSTask 运行脚本。

循环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
