iPhone:如何从左到右执行presentModalViewController动画

Question

我正在展示带动画的模型视图.默认情况下,它来自自下而上.如何让动画从左到右？我知道我可以使用导航控制器.但实际上,呈现视图不需要导航栏,并且模态呈现的视图也不需要导航栏.我仍然希望从左到右过渡.

Answer 1

您可以使用以下代码在呈现视图控制器的同时从右向左进行动画处理

CATransition *transition = [CATransition animation];
            transition.duration = 0.4;
            transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
            transition.type = kCATransitionPush;
            transition.subtype = kCATransitionFromRight;
            [self.view.window.layer addAnimation:transition forKey:nil];
            [self presentViewController:localitiesView animated:NO completion:nil];

Answer 2

只有四个UIModalTransitionStyle:

UIModalTransitionStyleCoverVertical
UIModalTransitionStyleFlipHorizontal
UIModalTransitionStyleCrossDissolve
UIModalTransitionStylePartialCurl

就像你说的那样,导航控制器将推动这种方式.如果您不想使用它,则必须自己为视图设置动画.
