• UIView转场动画

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    self.imageIndex++;
    if (self.imageIndex > 43) return;

    NSString *imageName = [NSString stringWithFormat:@"a%ld",self.imageIndex];

    //添加转场动画
    [UIView transitionWithView:self.imageView duration:1 options:UIViewAnimationOptionTransitionCurlUp animations:^{
        self.imageView.image = [UIImage imageNamed:imageName];
    } completion:nil];

}

界面跳转动画

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    MyViewController *myVC = [[MyViewController alloc]init];
    /*
    UIModalTransitionStyleCoverVertical
    UIModalTransitionStyleFlipHorizontal
    UIModalTransitionStyleCrossDissolve
    UIModalTransitionStylePartialCurl
     */
    //设置跳转动画的类型
    myVC.modalTransitionStyle = UIModalTransitionStylePartialCurl;

    [self presentViewController:myVC animated:YES completion:nil];
