After several tries, I found the next to work the best :
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
if((toInterfaceOrientation == UIDeviceOrientationLandscapeLeft) || (toInterfaceOrientation == UIDeviceOrientationLandscapeRight)) {
NSLog(@”didRotateFromInterfaceOrientation Landscape”);
isPortrait = NO; //Global variable
}
else {
NSLog(@”didRotateFromInterfaceOrientation Potrait”);
isPortrait = YES;
}

I tried to compile my code against 3.2 (in order to test in ipad simulator), but I got the following error:
“can not find protocol NSXMLParserDelegate”
I added the following line for the first warning, and all the 22 warnings were gone (and even the code worked :) )
#if __IPHONE_OS_VERSION_MIN_REQUIRED >= __IPHONE_4_0
@protocol NSXMLParserDelegate
@end
#endif
@interface MGTwitterXMLParser : NSObject <NSXMLParserDelegate> {
In case of application crash :
1) Get the log file : http://aplus.rs/apple/how-to-find-crash-logs-for-iphone-applications-on-mac-vista-and-xp/
2) Open the Organizer in xCode
3) Drag the log into the ‘Device Logs’ on the right side
Good luck…
When adding a shape (non standard) to your box2d project, you need to define the vertices of the shape.
Remember that the (0,0) is in the middle of the Sprite.
Or you can use this great tool to help you :

If you get compilation errors after adding:
#import “Box2D.h”
Change the file ext to .mm => This should tell the compiler to use C++, and solve the problem
