过去几个小时我一直在寻找，我无法弄清楚这一点。我正在Obj-C中为iOS创建一个钛模块。该模块编译得很好。我的测试项目可以看到模块，但是，我一直收到这个错误：
Invalid method (createView) passed to TiVolumesliderModule at app.js
我的app.js包含
var VolumeSlider = require('ti.volumeslider'); //-- this works
Titanium.API.info("module is => "+VolumeSlider); //-- this works: module is => [object TiVolumesliderModule]
var volumeSlider = VolumeSlider.createView({
width: '90%',
height: 'auto',
color: '#000',
bottom: 10,
});
我的Obj-C文件如下。我对Obj-C不太熟悉所以我为发布这些长文件而道歉。

答案 0 :(得分：2)
根据过去的经验，这可能是由一些不同的事情造成的。
您的文件名的大小写和前缀很重要。我看到与视图和视图代理有些不一致。确保所有内容都有此前缀：TiVolumeslider（小写s），然后是Module或View或ViewProxy。 Titanium可以将ViewProxies与Module以及View与ViewProxy相关联。
接下来，确保已将视图和视图代理.h和.m文件添加到Xcode项目中。在Xcode中打开TiVolumeslider.xcodeproj，然后将4个视图/视图代理.h和.m文件拖到Classes组中。它会询问您是否要将它们添加到您执行的各种目标中，因此请保留默认值，添加文件，然后重试。
