我正在沙盒化一个使用脚本桥来访问iTunes的osx应用程序。
for(iTunesFileTrack* track in fileTracks)
{
//url is nill in sandbox mode but good value in non sandbox mode
NSURL* url = [track location];
NSString* sourceFile = [[track location] path];
if(sourceFile == nil)
{
NSLog(@"Sourcefile for the track %@ was nil", track);
continue;
}
}
返回nil，我正在使用以下权利

控制台显示以下违规行为
iTunes[1592]: AppleEvents/sandbox: Returning errAEPrivilegeError/-10004 and denying dispatch of event core/getd from process 'TestiTunesAccess'/0x0-0x4d04d, pid=1789, because it is not entitled to send an AppleEvent to this process.
它在10.7中运行正常并且位置返回OK，但在10.8和10.9中因为脚本目标权利是活动的，我可以迭代库但轨道的位置是零，为什么会这样？如果我只是使用临时异常并删除部分：在10.8之前就可以了。
但是，由于Apple建议我们在10.8+中使用脚本目标而不是临时例外权利，我使用的是推荐的。任何帮助都将受到高度赞赏。
