推送intel-xdk文件后,Pixi.js触摸事件没有在iPhone上触发

标签: javascript intel-xdk pixi.js

我创建了一个小型测试项目来复制问题。 该项目仅包含pixi.min.js和index.html,其中包含此示例中的代码:

http://pixijs.github.io/examples/index.html?s=demos&f=interactivity.js&title=Interactivity

当我通过浏览器测试时按钮工作。 它们也适用于intel-xdk emulate标签。

但是当我转到test标签,推送文件,扫描二维码以打开iphone上创建的应用程序时,会出现按钮,但触摸事件无效。

为什么触摸事件不会在iPhone上触发?

var textureButton = PIXI.Texture.fromImage('images/button.png');
var textureButtonDown = PIXI.Texture.fromImage('images/button.png');
var textureButtonOver = PIXI.Texture.fromImage('images/button2.png');

它正在iPhone上运行,但由于您的初始按钮图像textureButtontextureButtonDown相同(button.png),因此您看不到任何事情。因此,当您触摸它时,您在屏幕上看不到任何差异。在iPhone上,触摸事件没有hover事件,因此未应用textureButtonOver

但是当你在模拟器上测试时,你正在使用鼠标,所以当你将鼠标移到按钮textureButtonOver上时,你会看到屏幕上的变化。

所以将textureButtonDown更改为其他图片(button3.png),你会看到它在iPhone上运行
