次のコードのようなものを使用する必要があります。
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(rotationChanged:)
name:@"UIDeviceOrientationDidChangeNotification"
object:nil];
次に、方向に応じてビューを変更します。
-(void)rotationChanged:(NSNotification *)notification{
NSInteger orientation = [[UIDevice currentDevice] orientation];
UIWindow *_window = [[[UIApplication sharedApplication] delegate] window];
switch (orientation) {
case 1:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.4];
[_window setTransform:CGAffineTransformMakeRotation (0)];
[_window setFrame:CGRectMake(0, 0, 320, 480)];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES];
[UIView commitAnimations];
break;
case 2:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.4];
[_window setTransform:CGAffineTransformMakeRotation (M_PI)];
[_window setFrame:CGRectMake(0, 0, 320, 480)];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES];
[UIView commitAnimations];
break;
case 3:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.4];
[_window setTransform:CGAffineTransformMakeRotation (M_PI / 2)];
[_window setFrame:CGRectMake(0, 0, 320, 480)];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:YES];
[UIView commitAnimations];
break;
case 4:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.4];
[_window setTransform:CGAffineTransformMakeRotation (- M_PI / 2)];
[_window setFrame:CGRectMake(0, 0, 320, 480)];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:YES];
[UIView commitAnimations];
break;
default:
break;
}
}
それが役立つことを願っています:P
