如何在另一个ViewController之上显示一个ViewController？

Question

Let's say I have a class that is a subclass of UIViewController named FullSizeViewController . I also have another class that is a subclass of UIViewController called TQHViewController (TQH: Three Quarter Height). How would I

1. be able to display TQHViewController over FullSizeViewController , with the only one quarter of FullSizeViewController visible?

2. animate this action?

I'm basically attempting to make something like a UIPopover , but animate it so it slides in from the bottom of the screen.

Answer 1

@property(nonatomic,retain) TQHViewController   *template;

template = [[TQHViewController alloc]init];
template.view.frame = CGRectMake(20, 1000, 280, 450);

And you can also set the frame for the subView and decide the size of the subview. if you want animation from the bottom use UIViewwithanimation.

 [UIView animateWithDuration:0.9f
                      delay:0.1f
     usingSpringWithDamping:0.65f
      initialSpringVelocity:0.1f
                    options:UIViewAnimationOptionCurveEaseOut animations:^{
                template.view.frame = CGRectMake(20, 63, 280, 450);
                [self.view addSubview:overlayWindow];

               }

                 completion:^(BOOL finished) {
                     //Completion Block
  }];

Use like this so your functionalities will not be lost and make nill after the usage.
