iOS AssistiveTouch slow animation when using custom keyboard

由 邮差的信 提交于 2019-12-10 13:11:58
问题 I'm building an custom keyboard, everything is fine now, except when i'm using AssistiveTouch during my custom keyboard is enabled, the animation of AssistiveTouch is little bit laggy (slow zoom in , zoom out) when tap to open it. I tested on iPhone 4s and iPhone 6 , same trouble, so i think is not about device hardware or resource consume. Anyone having same trouble or know reason? and how to solve it ? 回答1: I found reason by myself. that because of shadow. i added shadow for each button,

Updating D3 streamgraph with new data

由 流过昼夜 提交于 2019-12-10 11:08:20
问题 I have a streamgraph and I would like to update it by changing its data. I have a line graph which transitions between data sets perfectly and I am trying to adapt the same code for my streamgraph but with little success. I can change the color of each stream but not the data. Here is my update line function function UpdateData() { // Get new data d3.csv("data2.csv", function(data) { data.forEach(function(d) { d.date = parseDate(d.date); d.age = +d.age; }); // Rescale range x.domain(d3.extent

对transition,transform,animation的疑惑

由 和自甴很熟 提交于 2019-12-10 03:07:57
名词解释 好吧,如果仅仅是按照百度字典的解释,我根本分辨不出,变换,变化,转换/化的意义 我们先来看一下百度翻译 transition: 过渡，转变，变迁; [语] 转换; [乐] 变调; transform: 变换; 改变; 改观; translate: 翻译; 转化; 解释; animation: 生气，活泼; 动画片制作，动画片摄制;动画片 最后一个animation可以理解,就是动画的意思,类似flash里面的祯动画(你没听过的话就当我没说). 恩恩,颤抖吧!!!英语渣的程序员们.其余三个果然是傻傻分不清楚. 我来举个例子,说明一下这些 变 的区别. animation就像 动画片 的制作一样,你需要先把每一页(@keyframes)提前画出来,然后他们先后展示,就组成了动画.注重的是场景的变化,你可以让页面中元素的多个属性进行变化,想改变什么,就改变什么. transform倾向于变换,比如自己变大变小,扭曲,旋转等,它指定了几种 常见的 . 简单的 动画.你拿过来就可以用,不用再自己绘制每个场景了,但是同样的,改变是有限的,你只能按照它给的那几个属性来操作. translate是transform中 常见的 . 简单的 动画中的一种,就是简单的改变元素的 宽高 transition是过渡,倾向于描述 变化过程 ,是的以上所有的变化都是需要一个时间来完成的

Shared Element Transition (Foreground/Background) Issue

由 左心房为你撑大大i 提交于 2019-12-10 02:48:43
问题 I would like to know whether it is possible to change the z-order of a shared element transition? Look: I have a layout with an image, that fills the whole screen. In front of the image is a textbox which shows the title of the image. If I klick on the textbox, the transition to the detail activity starts. Therefore I implemented a shared element transition, in which the fullscreen image animates to a smaller version of itself in the detail view. The picture below illustrates this behaviour.

CSS3 transition实现超酷动画效果

由 旧巷老猫 提交于 2019-12-10 02:36:21
一、前面的感慨 以前也陆陆续续试过CSS3的一些特性，文字投影，多边框等。但都是试试而已，知道有这么回事。今天，见到了一个新玩意，transition，认认真真的试了一下，经过，我懵了，我呆了，我傻了，半天说不出话来，这…这…unbelievable，amazing，太神奇了，太不可思议了，几行简单的CSS，如此炫酷的动画效果，flash都不及的动画效果，我真是难以表达我的心情。 下面由浅入深，使用纯CSS，一步一步实现图片墙动画效果。这里，必须要先说明一下：对于对于此transition效果，IE6,IE7,IE8浏览器可以回家过元旦节了，这里没有它们的事情，Firefox3虽然平时表现不错，这里也没有它的事情。这个效果最拿手的是chrome2浏览器，Safari4，也就是webkit家族，这里Firefox3.5勉强凑合，有盒阴影和旋转效果，但是没有动画。所以，下文陆续提供的demo页面仅适用于chrome浏览器和Safari浏览器，部分适用于Firefox3.5+，IE纯粹的观众。 二、基础练习 – 实现旋转与盒投影效果 在CSS3中，实现旋转效果需要用到transform属性中的rotate属性；实现盒阴影效果需要使用box-shadow属性。具体参见下面的示例代码。 -webkit-transform:rotate(10deg); -moz-transform
