How to delete all the files under my app's NSDocumentsDirectory?

Question

I tried using

NSString *DocumentsDirectoryPath = //Code to fetch the Documents Directory Path;
NSError *error;
NSFileManager *manager = [NSFileManager defaultManager];
[manager removeItemAtPath:DocumentsDirectoryPath error:&error];

The above code deletes the whole Documents directory of my app, but I just want to delete contents of the Documents directory not the Documents directory itself.

What should I do?

 NSString *docsDir = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
 NSFileManager *localFileManager=[[NSFileManager alloc] init];
 NSDirectoryEnumerator *dirEnum = [localFileManager enumeratorAtPath:docsDir];

 NSString *file;
 NSError *error;
 while ((file = [dirEnum nextObject])) 
 {
     NSString *fullPath = [NSString stringWithFormat:@"%@/%@", docsDir,file];
     // process the document
     [localFileManager removeItemAtPath: fullPath error:&error ];
 }
 [localFileManager release];

Correct me if i am wrong but it's NSError *error not NSString *error – Ahmad Kayyali Mar 31 '11 at 12:45
@Mike: This does not delete the contents of the documents directory. – Parth Bhatt Mar 31 '11 at 12:56
Try it now - I added the missing line that creates the full path. – Rayfleck Mar 31 '11 at 13:02

@Rayfleck: I am having a warning at the this code block **while (file = [dirEnum nextObject])** – Ahmad Kayyali May 20 '11 at 13:06
using iOS 4.3, to avoid this you need to change this block to `while ((file = [dirEnum nextObject]))` – Ahmad Kayyali May 20 '11 at 13:15
I added the () to the code sample above. Thanks to all of you for keeping me honest. – Rayfleck May 20 '11 at 13:30

I think it's better to use [docsDir stringByAppendingPathComponent:file]; rather than stringWithFormat – LightMan Sep 27 '13 at 18:28
