如何让一个UIViewController实现自定义转场效果

Step 1

vc.modalPresentationStyle = UIModalPresentationCustom

Step 2

vc.transitioningDelegate = HWModalTransition object

Step 3

实例化HWModalTransition object

// present转场对象
present = [HWTransitionAnimator animatorWithDuration:0.15 animate:^(HWModalTransitioningContext *context, HWCompleteBlock complete) {

  // 可根据需求对某些view添加手势
  [context.containerView addGestureRecognizer:[UITapGestureRecognizer gestureRecognizerWithHandler:^(__kindof UIGestureRecognizer *ges) {
      [context.presentedVC dismissViewControllerAnimated:YES completion:nil];
      }]];


  // 自定义你的动画效果
  context.toVC.view.frame = CGRectMake(0, screenSize.height, screenSize.width, screenSize.height * 0.5f);
  [UIView animateWithDuration:0.15 delay:0.0 usingSpringWithDamping:10 initialSpringVelocity:10 options:UIViewAnimationOptionCurveEaseInOut animations:^{
  
    context.toVC.view.top = screenSize.height * 0.5f;
    
    } completion:^(BOOL finished) {
      complete(); // 动画结束一定要调用这个block块，否则转场未完成下一次无法继续转场
    }];
}];

// dismiss转场对象
dismiss = [HWTransitionAnimator animatorWithDuration:0.15 animate:^(HWModalTransitioningContext *context, HWCompleteBlock complete) {

  // 自定义你的动画效果
  [UIView animateWithDuration:0.15 delay:0.0 usingSpringWithDamping:10 initialSpringVelocity:10 options:UIViewAnimationOptionCurveEaseInOut animations:^{
  
      context.fromVC.view.top = screenSize.height;
      
    } completion:^(BOOL finished) {
      complete(); // 动画结束一定要调用这个block块，否则转场未完成下一次无法继续转场
    }];
}];

HWModalTransition object = [HWModalTransition transitionWithPresentAnimator:present dismissAnimator:dismiss];

如何支持手势交互？

在适合的view上添加手势， 手势处理方法中调用以下方法更新转场动画进度

- (void)updateTransitionWithPercentComplete:(CGFloat)percent forOperation:(HWModalTransitionOperation)operation
 status:(HWTransitionStatus)status;

注意： 1、对于一个已经处于percent状态的vc，手势交互时以上方法operation参数应该传HWModalTransitionOperationDismiss，因为你不可以再一次percent这个vc； dismiss 状态也一样 2、以上方法如果status状态传 HWTransitionStatusFinish 或 HWTransitionStatusCancel 时，percent参数是会被忽略的
