推荐答案

您只能写入应用程序的沙箱目录.下面是一个函数，它将为您的应用返回文档文件夹的路径.

You can only write to your application's sandbox directory. Below is a function that will return the path to the Documents folder for you app.

- (NSString *)applicationDocumentsDirectory
{
    return [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
}
