Answer 1

请参阅类中的以下方法NSFileManager：

- (BOOL)createDirectoryAtPath:(NSString *)path attributes:(NSDictionary *)attributes
- (BOOL)createDirectoryAtPath:(NSString *)path withIntermediateDirectories:(BOOL)createIntermediates attributes:(NSDictionary *)attributes error:(NSError **)error

另请注意，您不能将任何内容写入 application bundle。然而，应用程序沙箱包含几个您可以编写的文件夹（它们之间的选择取决于您的需要）。有关详细信息，请参阅“常用目录”。
