对嵌入 applescript 的 Objective-C 应用程序进行沙箱处理

Question

我想对一个应用程序进行沙箱处理，该应用程序使用 applescript 联系 safari 以获取选项卡列表。然后我通过 NSAppleEventDescriptor 在目标 c 中取回这些数据。 我已经将 com.apple.security.temporary-exception.apple-events 密钥和 com.apple.safari 添加到我的权利中。 当我的应用程序没有沙箱化时，我没有问题，但是当我尝试沙箱化它时，我只是得到“null”作为数据。

applescript 列出选项卡并将其作为 xml 返回。

tell application "Safari"
set listeSite to {{"http://www.deezer.com", "deezer"}}
set resp to "<?xml version=\"1.0\" encoding=\"iso-8859-1\"?>"
repeat with aWindow in windows
repeat with aTab in tabs of aWindow
set URLTab to URL of aTab
repeat with aSite in listeSite          
if URLTab starts with item 1 of aSite then
set oktabURL to URL of aTab
set oktabWindowID to id of aWindow
set resp to resp & "<site><url>" & oktabURL & "</url><windowID>" & oktabWindowID & "</windowID><type>" & item 2 of aSite & "</type></site>"
end if
end repeat
end repeat
end repeat

return resp

end tell

将数据返回到目标 c

NSString *path = [[NSBundle mainBundle] pathForResource:@"hello" ofType:@"scpt"];    
NSAppleScript *script = [[NSAppleScript alloc] initWithContentsOfURL:[NSURLfileURLWithPath:path] error:nil];
NSAppleEventDescriptor *result = [script executeAndReturnError:nil];
NSLog(@"result == %@", result);
DescType descriptorType = [result descriptorType];
NSLog(@"descriptorType == %@", NSFileTypeForHFSTypeCode(descriptorType));
NSString *responseValue = [result stringValue];
NSLog(@"value == %@", responseValue);
[label setStringValue:responseValue];
NSData *data = [result data];
NSXMLDocument *xmlResponse = [[NSXMLDocument alloc] initWithData:data options:(NSXMLNodePreserveWhitespace|NSXMLNodePreserveCDATA) error:nil];
NSLog(@"xml == %@", xmlResponse);
