  • Interface builder UIButton custom background image not working on simulator/device

    - by xenonii
    I'm trying to do something really simple. I have an image for a button and I'm trying to set it on a custom button in interface builder. I set the background image accordingly (no case sensitivity problem here). In interface builder it shows up, but in the simulator or on the device it doesn't appear at all. Just the button's text will appear. Do I need to turn on some flag or something of the sort?

  • Interface Builder can't see classes in a static library

    - by teabot
    I have refactored some UIView sub-classes into a static library. However, when using Interface Builder to create view components for a project that uses the static library I find that it is unaware of the library classes. What do I need to do to make the class interfaces visible to Interface Builder? Update: The correct answer refers to dragging the headers into the 'XIB browser'. The '.h' files can be dragged from a finder window to the window area identified in this image:

  • Common header view on top of nib files with Interface builder

    - by Tiago
    Hi, I have a nib file that contains an header that will be used in most of my views, so that I can change it's layout just once when I need. I'd like to know if it's possible to add the header nib view with interface builder, or if I need to do that programmatically and how should it be done. I've thought about setting the subclass of the subview to a UIView subclass that automatically loads the nib file, but I'd like to do that with interface builder. Is that possible?

    - by kunjaan
    I am learning Java and just found that the Interface can have fields, which are public static and final. I haven't seen any examples of these so far. What are some of the use cases of these Interface Constants and can I see some in the Java Standard Library?

  • Trouble creating a button matrix in Interface Builder

    - by Jake
    Hi, I am trying to create a matrix of buttons in Interface Builder 3.2.1 but can not find anyway to do it.

Have I missed something? Thanks.

  • Interface in a dynamic language?

    - by Bryan
    Interface (or an abstract class with all the methods abstract) is a powerful weapon in a static language. It allows different derived types to be used in a uniformed way. However, in a dynamic language, all objects can be used in a uniformed way as long as they define certain methods. Does interface exist in dynamic languages? It seems unnecessary to me.

  • Anonymous class implementing interface

    - by Flo
    I have the following code inside a method: var list = new[] { new { Name = "Red", IsSelected = true }, new { Name = "Green", IsSelected = false }, new { Name = "Blue", IsSelected = false }, }; I would like to call a function that requires a list of elements with each element implementing an interface (ISelectable). I know how this is done with normal classes, but in this case I am only trying to fill in some demo data. Is it possible to create an anonymous class implementing an interface? like this: new { Name = "Red", IsSelected = true } : ISelectable

  • Advantages/disadvantages of browser-based interface vs. graphics

    - by Josh
    Hello everyone, I'm in the design phase for a desktop-based application. Because of the nature of this particular application, I believe it would benefit greatly from a web-based approach (i.e., allowing a user to interface with the application through a browser running in kiosk mode) in order to leverage the simplicity of HTML/CSS/JS and the availability of many great JS interface plugins. Does taking this approach (rather than coding in a native or cross-platform graphics library) come with any gotchas?

    Would be correct the next way to implement the methods attached to an interface?
