I am working on iPhone game, i was curious to know if there is a call back function tht gets called when the device forces auto rotation on the game, so that i can change the HUD elements.
Or shd i run infinite loop that checks if the app has rotated in a different thread? problem is i dont think this is an effective way. Does anyone have any good solution for this.
Yes there is, as long as the device is not orientation locked you can register to listen to
which can be seen here http://developer.apple.com/library/ios/#documentation/uikit/reference/UIDevice_Class/Reference/UIDevice.html
If you want to overcome the possibility of the device being orientation locked, then you have to manually monitor the accelerometer of the device.
In a game where orientation is essential, manually monitoring is recommended, since the first method has a little delay.
