Comment supporter les orientations ?

Project

UIViewController

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation{

return UIInterfaceOrientationIsLandscape(orientation);}

Comment gérer la rotation ?

enum {UIViewAutoresizingNone,UIViewAutoresizingFlexibleLeftMargin,UIViewAutoresizingFlexibleWidth,UIViewAutoresizingFlexibleRightMargin,UIViewAutoresizingFlexibleTopMargin,UIViewAutoresizingFlexibleHeight,UIViewAutoresizingFlexibleBottomMargin

};

UIView

@property (nonatomic) UIViewAutoresizing autoresizingMask

[myView setAutoresizingMask:(UIViewAutoresizingFlexibleLeftMargin| UIViewAutoresizingFlexibleTopMargin|

UIViewAutoresizingFlexibleRightMargin| UIViewAutoresizingFlexibleBottomMargin)];

UIViewAutoresizing

[myView setAutoresizingMask:(UIViewAutoresizingFlexibleLeftMargin| UIViewAutoresizingFlexibleBottomMargin)];

UIViewAutoresizing

[myView setAutoresizingMask:(UIViewAutoresizingFlexibleWidth| UIViewAutoresizingFlexibleTopMargin|

UIViewAutoresizingFlexibleBottomMargin)];

UIViewController

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)orientation duration:(NSTimeInterval)duration

- (void)didRotateToInterfaceOrientation:(UIInterfaceOrientation)orientation duration:(NSTimeInterval)duration

Comment être prévenu des rotations ?

} UIInterfaceOrientation;

typedef enum {UIDeviceOrientationUnknown,UIDeviceOrientationPortrait,UIDeviceOrientationPortraitUpsideDown,UIDeviceOrientationLandscapeLeft,UIDeviceOrientationLandscapeRight,UIDeviceOrientationFaceUp,UIDeviceOrientationFaceDown

} UIDeviceOrientation;
