With these it helps Use WindowManager.LayoutParams.TYPE_SYSTEM_ERROR instead of WindowManager.LayoutParams.TYPE_PHONE that will solve the issue. This will make the view able to listen to touch events,. However you can use WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY also but it wont listen to touch events

it should still fix some issue CFUserNotificationCreate is your friend.
Not in the official iPhone SDK? Too bad, I remember that a year ago on the big presentation of the yet-to-come SDK, an Apple evangelist/chief saying that the SDK would include exactly the same API as used internally by Apple... Pfff...

like below fixes the issue This was a silly question. I wasn't fully understanding delegates.
I'm providing the answer for people that happen to stumble upon this.
code :
@interface SampleAppAppDelegate : NSObject <UIApplicationDelegate, CPLockControllerDelegate> {
- (void)applicationDidFinishLaunching:(UIApplication *)application {    
    // Override point for customization after app launch    
    [window addSubview:viewController.view];

    CPLockController *lockController = [[CPLockController alloc]initWithStyle:CPLockControllerTypeAuth];
    lockController.passcode = @"1234";
    lockController.delegate = self;
    lockController.title = @"Passcode is 1234";
    lockController.modalPresentationStyle = UIModalPresentationFormSheet;
    [viewController presentModalViewController:lockController animated:NO];

    [window makeKeyAndVisible];
}

To fix the issue you can do I'm having the following issue - I'm having a view that I'm putting inside the WindowManager and I would like it to come in translate animation from out of the screen and toward the middle of the screen. , I just faced the same issue and the actual flag is:
code :
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        300, 400, WindowManager.LayoutParams.TYPE_PHONE,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
        PixelFormat.TRANSLUCENT);

To fix this issue My main goal is to show UI (With EditText, so IME support) Over the lock screen (No matter if there's PIN/Code or simple lock screen). , Add this in onCreate() of your Activity:
code :
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
}
