IOS切换视图动画

主要代码

#define degreesToRadians(x) (M_PI * (x) / 180.0)  //角度和弧度之间转换
@interface ViewController ()

@end

@implementation ViewController

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
    if (toInterfaceOrientation == UIInterfaceOrientationPortrait) {
        self.view = self.portrait;
        self.view.transform = CGAffineTransformIdentity;
        self.view.transform =
        CGAffineTransformMakeRotation(degreesToRadians(0));
        self.view.bounds = CGRectMake(0.0, 0.0, 320.0, 460.0);
    }else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft){
        self.view = self.landscape;
        self.view.transform = CGAffineTransformIdentity;
        self.view.transform =
        CGAffineTransformMakeRotation(degreesToRadians(-90));
        self.view.bounds = CGRectMake(0.0, 0.0, 480.0, 300.0);
    }else if(toInterfaceOrientation == UIInterfaceOrientationLandscapeRight){
