一般在做自定義彈框時或者點選展示大圖時用的較多。不說了上程式碼https://github.com/YST521/DEMOLIST.git

//第一步A頁面跳轉到B頁面

           MOdalPopController * popVC = [MOdalPopController new];

            popVC.view.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.3];

            popVC.modalPresentationStyle = UIModalPresentationOverCurrentContext;

            self.modalPresentationStyle = UIModalPresentationCurrentContext;

[self presentAnimal]; //跳轉動畫

[self.navigationController presentViewController:popVC animated:NO completion:nil];

//

-(void)presentAnimal{

    CATransition *animation = [CATransition animation];

    animation.duration = 0.3;

    animation.type = kCATransitionFade;

    animation.subtype = kCATransitionFromTop;

    [self.view.window.layer addAnimation:animation forKey:nil];

    [self dismissViewControllerAnimated:NO completion:0];

}

//如果[self.navigationController presentViewController:popVC animated:NO completion:nil];裡面動畫為YES則是模態的那幾種動畫效果

B頁面。dismiss 同樣去掉了動畫效果 重新添加了動畫

-(void)dismiss{

    CATransition *animation = [CATransition animation];

    animation.duration = 0.3;

    animation.type = kCATransitionFade;

    animation.subtype = kCATransitionFromTop;

    [self.view.window.layer addAnimation:animation forKey:nil];

    [self dismissViewControllerAnimated:NO completion:0];

}
