ios5旋转银屏

ios5旋转屏幕

ios5旋转屏幕：（以下为关健代码，附件中有实例）

竖屏和横屏是两个不同的ViewController，在实现时需建两个viewController

?

//屏幕旋转
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
???
??? if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) {
??????? //场景跳转方式一
??????? [self performSegueWithIdentifier:@"LandscapeID" sender:self];
??????? //场景跳转方式二(编程方式实现)
//??????? UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
//??????? LandscapeViewController *land = [mainStoryboard instantiateViewControllerWithIdentifier:@"myLandscape"];
//??????? land.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
//??????? [self presentViewController:land animated:YES completion:nil];
??????? return YES;
??? }else if(toInterfaceOrientation == UIInterfaceOrientationPortrait) {
???????
??????? return YES;
??? }else {
??????? return NO;
??? }
}

//相关旋转方法可以测试下

//旋转方向发生改变时 -(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation?duration:(NSTimeInterval)duration?{??}?

//视图旋转动画前一半发生之前自动调用??-(void)willAnimateFirstHalfOfRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation?duration:(NSTimeInterval)duration?{??}?

//视图旋转动画后一半发生之前自动调用??-(void)willAnimateSecondHalfOfRotationFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation?duration:(NSTimeInterval)duration?{??}?

//视图旋转之前自动调用??-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation?duration:(NSTimeInterval)duration?{??}?

//视图旋转完成之后自动调用??-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation?{??}?

//视图旋转动画前一半发生之后自动调用?
-(void)didAnimateFirstHalfOfRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation?{
