Answer 1

Try this code

[self.view bringSubviewToFront:yoursubview];
CATransition *animation = [CATransition animation];
[animation setType:kCATransitionFade];
[animation setDuration:1.00];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                              kCAMediaTimingFunctionEaseIn]];
[yoursubview.layer addAnimation:animation forKey:@"fadeTransition"];

Answer 2

Change the frame of the subview insite the UIView Animation, like as follows,

initially set the

subView.frame=CGRectMake(0,self.view.frame.size.height,your_width,your_height);

then set the required frame position inside the animation

[UIView animateWithDuration:0.25 delay:0 options: UIViewAnimationCurveEaseOut animations:^ {

        // set subView's frame

    } completion:^(BOOL finished) {

    }
     ];

Answer 3

Try to use UIView animation block:

yourView.frame = CGRectMake(0, yourSuperView.frame.size.height, yourView.frame.size.width, yourView.frame.size.height);
[yourSuperView addSubview:yourView];
[UIView animateWithDuration:1.0 animations:^{
    yourView.frame = CGRectMake(0, 0, yourView.frame.size.width, yourView.frame.size.height);
} completion:^(BOOL finished) {
    //Task to do on Animation completion.
}];

You change the animation duration according to your convince. Also you can use following:

[UIView animateWithDuration:1.0 animations: {
      //your Implemntation
}];

or

[UIView animateWithDuration:1.0 delay:0 options:UIViewAnimationCurveEaseIn animations:^{
    
} completion:^(BOOL finished) {
    
}];

Please check the UIView class reference for animation option in UIViewAnimationOptions section and detail of methods.

If you only want to use CATransition

CATransition *animation = [CATransition animation];
[animation setType:kCATransitionMoveIn];
[animation setSubtype:kCATransitionFromTop];
[animation setDuration:0.6f];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                              kCAMediaTimingFunctionEaseInEaseOut]];
[subview.layer addAnimation:animation forKey:@"someTransition"];
