• How to check in which position (landscape or portrait) os the iPhone now?

  - by Knodel

  I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation. If I write just - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) if (interfaceOrientation == UIInterfaceOrientationPortrait|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { //Code } else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) { //Code } } The view just goes crazy if user rotated the device before shaking. Is there a method to get iPhones current orientation?

  The first one below works, but, just wanted to see if there's a better way... If I'm trying to find all records that start with 'C' with either a flag of 2 or a status of 9, do I need to incorporate the 'C' criteria twice? i.e., "SELECT * FROM mytable WHERE name like 'C%' AND flag = 2 OR name like 'C%' AND status = 9" Or, is there a way quicker way to write it so that I only need to set 'C%' once?
