目前presentingVC的动画没有可配置参数,其动画时间依赖- (NSTimeInterval)transitionDuration;
你的需求是什么,因为目前动画分2段,暴露参数的话需要2个可配置参数来处理。

请原谅我的钻牛角尖 (~ ̄▽ ̄)~
仔细观察了下京东的加购, 发现动画的细节是有一定差异的
if ([presentable shouldAnimatePresentingVC]) {
[UIView animateWithDuration:duration * 0.4 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
CATransform3D tran = CATransform3DIdentity;
tran.m34 = -1 / 1000.0f;
tran = CATransform3DRotate(tran, M_PI / 16, 1, 0, 0);
tran = CATransform3DTranslate(tran, 0, 0, -100);
fromVC.view.layer.transform = tran;
} completion:^(BOOL finished) {
[UIView animateWithDuration:duration * 0.6 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
fromVC.view.layer.transform = CATransform3DMakeScale(0.93, 0.93, 1);
} completion:^(BOOL finished) {
}];
}];
}
[UIView animateWithDuration:[presentable transitionDuration] * 0.6 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
toVC.view.layer.transform = CATransform3DIdentity;
} completion:^(BOOL finished) {
}];
您动画的核心代码是上述, present时设置了CATransform3D, dismiss时是直接恢复初始值。目前api是无法修改这个动画的参数的。
之后应该可以加些可控的参数来自定义动画吧? 比如使用个配置个block

你是想要高度自定义该动画还是只是修改参数?

高度自定义 自己来操控 fromVc和toVc的transform
from hwpanmodal.
hi, 完全高度自定义fromVC & toVC不现实,该框架原始初衷是从底部弹出视图,手势拖拽dismiss视图。
针对present动画的配置项很多,无须使用者再去手写代码高度自定义toVC的动画。
如果你有需求,后面考虑针对presenting VC动画提供接口。
