如何在目标c中创建sqlite函数。 调用插入查询的函数。

import android.app.Activity;
import android.graphics.Typeface;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;


public class TimerActivity extends Activity {

    public EditText edtNumber;
    public TextView txtCounter;
    public Button   btnStart;

    public Typeface time_font;

    String          num;
    int             get_number=0;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.timer);

        txtCounter = (TextView) findViewById(R.id.txtCounter);
        edtNumber = (EditText) findViewById(R.id.edtNumber);
        btnStart = (Button) findViewById(R.id.btnStart);

        time_font = Typeface.createFromAsset(getAssets(), "time_font.ttf");
        txtCounter.setTypeface(time_font);


        btnStart.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View view) {
                num = edtNumber.getText().toString();
                final int get_number = Integer.parseInt(num);
                txtCounter.setText(get_number + "");


                ThreadTimer counter = new ThreadTimer();
                counter.setSeconds(get_number);
                counter.setTextView(txtCounter);
                counter.start();

            }
        });

        txtCounter.setText(get_number + "");
    }
}
