NSFileManager delete contents of directory

Question

How do you delete all the contents of a directory without deleting the directory itself? I want to basically empty a folder yet leave it (and the permissions) intact.

Try this:

NSFileManager *manager = [NSFileManager defaultManager];
NSString *dirToEmpty = ... //directory to empty
NSError *error = nil;
NSArray *files = [manager contentsOfDirectoryAtPath:dirToEmpty 
                                              error:&error];

if(error) {
  //deal with error and bail.
}

for(NSString *file in files) {
    [manager removeItemAtPath:[dirToEmpty stringByAppendingPathComponent:file]
                        error:&error];
    if(error) {
       //an error occurred...
    }
}
