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.
E.g. by using a directory enumerator:
NSFileManager *fileManager = [[NSFileManager alloc] init];
NSDirectoryEnumerator *enumerator = [fileManager enumeratorAtPath:path];
NSString *file;
while (file = [enumerator nextObject]) {
NSError *error = nil;
BOOL result = [fileManager removeItemAtPath:[path stringByAppendingPathComponent:file] error:&error];
if (!result && error) {
NSLog(@"Error: %@", error);
}
}
Swift
let fileManager = NSFileManager.defaultManager()
let enumerator = fileManager.enumeratorAtURL(cacheURL, includingPropertiesForKeys: nil, options: nil, errorHandler: nil)
while let file = enumerator?.nextObject() as? String {
fileManager.removeItemAtURL(cacheURL.URLByAppendingPathComponent(file), error: nil)
}
