How to delete the contents of the Documents directory (and not the Documents directory itself)?

Question

I want to delete all the files and directories contained in the Documents directory.

I believe using [fileManager removeItemAtPath:documentsDirectoryPath error:nil] method would remove the documents directory as well.

Is there any method that lets you delete the contents of a directory only and leaving the empty directory there?

Answer 1

Try this:

NSString *folderPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 
NSError *error = nil;
for (NSString *file in [[NSFileManager defaultManager] contentsOfDirectoryAtPath:folderPath error:&error]) {
    [[NSFileManager defaultManager] removeItemAtPath:[folderPath stringByAppendingPathComponent:file] error:&error];
}

Answer 2

Swift 3.x

let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
guard let items = try? FileManager.default.contentsOfDirectory(atPath: path) else { return }

for item in items {
    // This can be made better by using pathComponent
    let completePath = path.appending("/").appending(item)
    try? FileManager.default.removeItem(atPath: completePath)
}
