How to access child views and their attributes?

Question

I am developing an iOS app using Rubymotion. I need to access a child label of a view to change it´s text.

How can I access child views (and their attributes) to modify them?

Thanks!

If you are using Xcode (Interface Builder) to design your views, then you'll want to use tagging to access your subviews. There are no properties in RubyMotion. It is possible to use attr_accessor to define the setter/getter for a property, but then there is no way to tell Interface Builder how to associate the control with the property name since Xcode doesn't understand the Ruby code. I have had success taking a project that was first written in Objective-C and using the .xib and .storyboard files in a RubyMotion project. In that case, if you create ivars with the same names as the properties in Objective-C, then everything will work.

If you are creating your UIViews programmatically, then you can store each subview in an ivar before adding the subview to the view.
