I want to build an iOS module in which I have a viewController class with its .xib file. now the problem is how to call that view from my titanium code. I know that there are vi
Check out the TiModdevguideDemoView.h/m and TiModdevguideDemoViewProxy.h/m in the mod dev guide for iOS:
https://github.com/appcelerator/titanium_modules/tree/master/moddevguide/mobile/ios/Classes
It demonstrates simply the relationship between views and view proxies. In this case, it makes a square.
You can see it being used in JavaScript here: https://github.com/appcelerator/titanium_modules/blob/master/moddevguide/mobile/ios/example/demos/viewproxyDemo.js
Once you have that in hand, and can make a simple view, you're ready to take the next step to solving your question. You need to convert your XIB to a NIB. The easiest way is to add the XIB to a native project, compile the project, and then pull out the NIB. Dump it in the assets for the module, and then reference it from your module code. I unfortunately don't have any public source that uses NIBs to link to, but I can show you a snippet. (A number of modules we maintain use this method, so I know that you can successfully get it working! Jira, Gigya, Urban Airship, and others.)
NSBundle* bndl = [NSBundle bundleWithPath:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"ti.jira/1.0/assets/JMC.bundle"]];
JMCSketchViewController *sketchViewController = [[[JMCSketchViewController alloc] initWithNibName:@"JMCSketchViewController" bundle:bndl] autorelease];
Note that we usually don't use NIBs unless we have something from a third party that forces us to. It's easier just to create the views imperatively rather than declaratively.
You can read more about views and view proxies in our iOS mod dev guide. Once you understand what I linked above in the mod dev guide (and successfully create your own), the mod dev guide will be much more useful to you. (I've got some updates to the guide in the pipeline that will make it easier to understand, by the way). http://docs.appcelerator.com/titanium/2.0/index.html#!/guide/iOS_Module_Development_Guide
Hope this helps. Let me know if there's anything I can further flesh out. There's a small hump of understanding for you to get over, but once you put some elbow grease in, you'll be running full speed with module development.
