Delete All Files in Documents Directory

The first approach I took was to loop through all the files, building a path to each, one by one:

1. // Path to the Documents directory
2. NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
3. if ([paths count] > 0)
4. {
5.   NSError *error = nil;  
6.   NSFileManager *fileManager = [NSFileManager defaultManager];
7.  
8.   // Print out the path to verify we are in the right place
9.   NSString *directory = [paths objectAtIndex:0];
10.   NSLog(@"Directory: %@", directory);
11.  
12.   // For each file in the directory, create full path and delete the file
13.   for (NSString *file in [fileManager contentsOfDirectoryAtPath:directory error:&error])
14.   {    
15.     NSString *filePath = [directory stringByAppendingPathComponent:file];
16.     NSLog(@"File : %@", filePath);
17.  
18.     BOOL fileDeleted = [fileManager removeItemAtPath:filePath error:&error];
19.  
20.     if (fileDeleted != YES || error != nil)
21.     {
22.       // Deal with the error...
23.     }
24.   }
25.  
26. }

 The code above works fine, however, I was interested in something that didn’t build each path separately – the code below deletes all the files in one fell swoop:

1. NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
2. if ([paths count] > 0)
3. {
4.   NSLog(@"Path: %@", [paths objectAtIndex:0]);
5.  
6.   NSError *error = nil;  
7.   NSFileManager *fileManager = [NSFileManager defaultManager];
8.  
9.   // Remove Documents directory and all the files
10.   BOOL deleted = [fileManager removeItemAtPath:[paths objectAtIndex:0] error:&error];
11.  
12.   if (deleted != YES || error != nil)
13.   {
14.     // Deal with the error...
15.   }
16.  

Given the requested item to remove was a directory, as you’d expect, not only were the files deleted, so was the Documents directory. Problem is, I ran into errors when I attempted to drag/drop new files into the file sharing areas iTunes.
To get things working again, I changed up the code above to create the Documents directory:

1. NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
2. if ([paths count] > 0)
3. {
4.   NSLog(@"Path: %@", [paths objectAtIndex:0]);
5.  
6.   NSError *error = nil;  
7.   NSFileManager *fileManager = [NSFileManager defaultManager];
8.  
9.   // Remove all files in the documents directory
10.   BOOL deleted = [fileManager removeItemAtPath:[paths objectAtIndex:0] error:&error];
11.  
12.   if (deleted != YES || error != nil)
13.   {
14.     // Deal with the error...
15.   }
16.   else
17.     // Recreate the Documents directory
18.     [fileManager createDirectoryAtPath:[paths objectAtIndex:0] withIntermediateDirectories:NO attributes:nil error:&error];
19.  
20. }

 Although there is less code to delete the Documents directory, something tells me it may simply be a better (and more robust) solution to loop and delete each file in sequence.
