Animate presentModalViewController from right /left
问题 Currently I am using [self presentModalViewController :newVC animated:YES] .I want to present newViewcontroller from left/right/top/bottom with a push effect. I tried to use CATransition but it displays a black screen in between the transition. 回答1: When present: CATransition *transition = [CATransition animation]; transition.duration = 0.3; transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; transition.type = kCATransitionPush; transition
