NSString *str_NS=[[url absoluteString] stringByReplacingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
NSLog(@"%@",str_NS);

NSLog(@"%@",str_NS);
string fullPath=[str_NS cStringUsingEncoding:NSASCIIStringEncoding];
directoryPathList.push_back(fullPath);
}
}
}
注意：要用
NSString *str_NS=[[url absoluteString] stringByReplacingPercentEscapesUsingEncoding: NSUTF8StringEncoding]; (见参考[2])
不能像 参考[1] 中那样写成
NSString *str_NS=[url absoluteString];
否则如果路径中带有空格，则会变成%20。
