获取资源文件夹路径的方法如下：

NSString *path = [[NSBundle mainBundle] resourcePath];

然而，在运行时您将无法在那里编写任何内容。新文件应保存到以下目录之一（取决于它们的用途）：

Documents directory - persists between app launches and backuped by iTunes

NSString* docPath = [NSSearchPathForDirectoriesInDomains
               (NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

Caches directory - persists between app launches but not backuped by iTunes - you should place there files that can be easily restored by your program to improve device backup time
```
NSString* cachesPath = [NSSearchPathForDirectoriesInDomains
               (NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0];
```
Temporary directory - may not persist between app launches
```
NSString* tempPath = NSTemporaryDirectory();
```
