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

Jam*_*May 5 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.它们也在intel-xdk emulate选项卡中工作.

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,按钮出现但触摸事件无法正常工作.

为什么触摸事件不会在iPhone上触发?

它可以在 iPhone 上运行,但您没有看到任何事情发生,因为您有初始按钮图像textureButtontextureButtonDown相同的 ( button.png)。因此,当您触摸屏幕时,您不会在屏幕上看到任何差异。在 iPhone 上没有hover触摸事件的事件,因此textureButtonOver不应用

但是当您在模拟器上测试时,您正在使用鼠标,因此当您将鼠标移动到按钮上时textureButtonOver,您会在屏幕上看到变化。

因此,将 更改textureButtonDown为不同的图像 ( button3.png),您将看到它在 iPhone 上运行
