向Progress Dialog添加延迟

private void showProgressDialogWithDelay(long delayMillis) {
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            // 显示Progress Dialog
        }
    }, delayMillis);
}

func showProgressDialogWithDelay(delay: TimeInterval) {
    DispatchQueue.main.asyncAfter(deadline: .now() + delay) {
        // 显示Progress Dialog
    }
}

function showProgressDialogWithDelay(delayMillis) {
    setTimeout(function() {
        // 显示Progress Dialog
    }, delayMillis);
}
