Interactive Delegate Methods Never Called

阅读更多关于 Interactive Delegate Methods Never Called

I want to make an interactive transition between a ViewController (1) and a NavigationViewController (2). The NavigationController is called by a button, so there's no interactive transition when presenting. It can be dismissed by a button or a UIPanGestureRecognizer, so it can be dismissed interactively or not. I have an object named TransitionManager for the transition, subclass of UIPercentDrivenInteractiveTransition. The problem with the code below is that the two delegate methods interactionControllerFor... are never called. Moreover, when I press the buttons or swip

问题 Hi I’m trying to use D3 to pause and resume a transition of a marker along a path like this example D3 tween - pause and resume controls plus stop the marker's transition on a particular data point like this D3 transition along segments of path and pause at coordinate values.

过渡：通过过渡transition，我们可以在不使用flash动画或JavaScript的情况下，当元素从一种样式变换为另外一种样式时为元素添加效果，要实现这一点，必须规定两项内容： 1.规定希望把效果添加到哪个CSS属性上 2.规定效果的时长 transition-property:添加过渡效果的样式属性名称 transition-duration:过渡效果的耗时:以秒作为单位 transition-timing-function:设置时间函数--控制运动的速度（linear匀速） transition-delay:过渡效果的延迟简写：transition:属性名称过渡时间时间函数延迟如果给多个属性添加过渡：transition:属性名称过渡时间时间函数延迟,属性名称过渡时间时间函数延迟; /*使用建议：因为transition最早是由webkit内核浏览器提出来的，而一些老版本的浏览器不支持，IE浏览器在十以上的版本才支持transition。所以在应用transition时需要添加上各自的前缀*/ 例如： -moz-transition:left 2s linear 0s; -webkit-transition:left 2s linear 0s; -o-transition:left 2s linear 0s; 手风琴菜单：添加过渡效果
