iphone中彈齣動畫的實現

問題描述：使用了下面的代碼：[plain]  FirstView * fir=[[FirstView alloc]init];  [self.navigationController pushViewController:fir animated:NO];   能否實現一個彈齣動畫？謝謝解決方案：[plain]  -(void)ButtonAction:(id)sender{    [self SwipeRight:self.navigationController.view];  // <--calling method    //[self.navigationController pushViewController:viewcontrollerobject animated:NO];    // or pop //   }        -(void)SwipeRight:(UIView *)view{            CATransition* transition = [CATransition animation];          [transition setDuration:0.3];          transition.type = kCATransitionPush;          transition.subtype = kCATransitionFromRight;          [transition setFillMode:kCAFillModeBoth];          [transition setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];          [view.layer addAnimation:transition forKey:kCATransition];       }        -(void)SwipeLeft:(UIView *)view{          CATransition* transition = [CATransition animation];          [transition setDuration:0.3];          transition.type = kCATransitionPush;          transition.subtype = kCATransitionFromLeft;          [transition setFillMode:kCAFillModeBoth];          [transition setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];          [view.layer addAnimation:transition forKey:kCATransition];       }
