UIView Анимации

Question

Почему этот код ничего не делает?

[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
[UIView setAnimationTransition:UIViewAnimationCurveEaseIn forView:self.view cache:YES];

[self.view removeFromSuperview];

[UIView commitAnimations];

Кроме того, где я могу увидеть весь список возможных аргументов для beginAnimations:?

Answer 1

Вы должны установить анимационный переход в представлении, содержащем изменение, например.

[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
                       forView:self.view.superview cache:YES];

Кроме того, переход должен быть константой типа UIViewAnimationTransition .

Метод +beginAnimations:context: может принимать любую строку в качестве 1-го аргумента и любой указатель в качестве 2-го аргумента.

Answer 2

Использование QuartzCore.framework С этими анимациями.

-(void)viewSlideInFromRightToLeft:(UIView *)views
{
    CATransition *transition = nil;
    transition = [CATransition animation];
    transition.duration = 0.5;//kAnimationDuration
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype =kCATransitionFromRight;
    transition.delegate = self;
    [views.layer addAnimation:transition forKey:nil];
}

-(void)viewSlideInFromLeftToRight:(UIView *)views
{
    CATransition *transition = nil;
    transition = [CATransition animation];
    transition.duration = 0.5;//kAnimationDuration
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype =kCATransitionFromLeft;
    transition.delegate = self;
    [views.layer addAnimation:transition forKey:nil];
}

-(void)viewSlideInFromTopToBottom:(UIView *)views
{
    CATransition *transition = nil;
    transition = [CATransition animation];
    transition.duration = 0.5;//kAnimationDuration
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype =kCATransitionFromBottom ;
    transition.delegate = self;
    [views.layer addAnimation:transition forKey:nil];
}

-(void)viewSlideInFromBottomToTop:(UIView *)views
{
    CATransition *transition = nil;
    transition = [CATransition animation];
    transition.duration = 0.5;//kAnimationDuration
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype =kCATransitionFromTop ;
    transition.delegate = self;
    [views.layer addAnimation:transition forKey:nil];
}

Для AnimationType можно использовать следующие параметры: kCATransitionMoveIn, kCATransitionPush, kCATransitionReveal, kCATransitionFade.

Для AnimationSubType можно использовать следующие параметры: kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom.
