• In an iPhone app, is it beneficial to tile a background image that has a pattern in it?

  - by Dr Dork

  Here's an example of the type of background image I'm talking about, the iPhone Notes app... Clearly, there's a pattern in it. My question is, if this were an iPad app and the background image was twice the size, would there be any significant benefits to taking advantage of this pattern by tiling the image? Or would it really make no difference in terms of performance and just be easier to load the entire image into a UIImageView? Thanks in advance for all your wisdom!

• What exactly are those data types int 16, int 32 and int 64 on the iPhone, in Core Data?

  The Xcode data modeler shows me those three different int data types. When I would write code, which data types do these really correspond to on the iPhone? Are they all simply NSInteger, wrapped in an NSNumber? As far as I see it, NSNumber only differentiates between int an NSInteger... so I guess those three end up beeing pretty much the same?

• Followed the official android documentations but still could not use SQLite in app

  - by user366539

  My DBHelper class public class DBHelper extends SQLiteOpenHelper { public DBHelper(Context context) { super(context,"SIMPLE_DB",null,1); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE SIMPLE_TABLE ( " + "ID INTEGER PRIMARY KEY " + "DESC TEXT);"); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { } } Activity class public class SimpleDatabase extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); DBHelper dbHelper = new DBHelper(this); SQLiteDatabase db = dbHelper.getReadableDatabase(); db.execSQL("INSERT INTO SIMPLE_TABLE VALUES (NULL, 'test');"); Cursor cursor = db.rawQuery("SELECT * FROM SIMPLE_TABLE", null); TextView text = (TextView)findViewById(R.id.textbox); text.setText(cursor.getString(0)); } } I figure it crashed (application has stopped unexpectedly!) at SQLiteDatabase db = ... because if I commented the code out from there to the end then it worked fine. But I have no idea whatsoever why it does that. Any help would be appreciated.
