  • Effect of 'myObj = [[[[MyClass alloc] init] autorelease] retain];'?

    - by filipe
    I've just downloaded the Facebook iOS SDK and I noticed that in the sample code that comes with the SDK whenever it creates an instance of the Facebook class it does it like this: _facebook = [[[[Facebook alloc] init] autorelease] retain]; where _facebook is a member variable of the calling object (i.e. not a local variable). Can anyone explain exactly what's the point of autoreleasing and then retaining it?

  • Injection of class with multiple constructors

    - by Jax
    Resolving a class that has multiple constructors with NInject doesn't seem to work. public class Class1 : IClass { public Class1(int param) {...} public Class1(int param2, string param3) { .. } } the following doesn’t seem to work: IClass1 instance = IocContainer.Get<IClass>(With.Parameters.ConstructorArgument(“param”, 1)); The hook in the module is simple, and worked before I added the extra constructor: Bind().To(); Thanks in advance...

  • Alternative for assigns() in Cucumber with Capybara?

    - by thillerson
    I'm trying out capybara with cucumber to get some better javascript test coverage. I have a lot of steps that check or use things from the Rails integration test helpers, for instance: assigns(:current_user).should_not be_nil No matter how I call assigns, even if I say something like p assigns it errors with: undefined method `template' for nil:NilClass (NoMethodError) So, it seems that I can't do that anymore. Is there an alternative to introspecting what's going on in the controller, or maybe some way of at least running those steps in such a way that I have the integration test stuff back?

  • Add rel="xx" to jQuery a.link elements

    - by Xavier
    I use a little jQuery script to run a simple music player, but I'd like to add a rel="player" to the links in this jQuery script (the play/stop button for instance). This way I can exclude these rel="player" links from another jQuery script I use, because I don't want it to take the rel="player" elements into account. I reckon this is fair simple but i don't really know how to to it. Here is the jQuery script of the player, if it's ever necessary: http://hyker.be/cv/js/jquery.simpleplayer.min.js

  • Find Rank in Microsoft Report

    - by Alex Essilfie
    Is there any way I can find the rank of a set of values in Microsoft Reports? For instance, in order to produce a table like the one below, what function/formula do I enter in the Rank column? +------+-----+ |Value | Rank| +------+-----+ | 12 | 3 | | 30 | 5 | | 5 | 1 | | 10 | 2 | | 24 | 4 | +------+-----+ Update Values in the value column are produced from calculations on the report-side so I cannot find the rank using a query.

  • Different ways of accessing configuration parameters from a JAX-WS service

    - by ecerulm
    As far as I know I can access the web.xml <context-param>s by making my class implement ServletContextListener and use the ServletContext.getInitParam(String) to read them, but it´s cumbersome as only one instance of the class will receive the contextInitialized(ServletContextEvent sce) call, so I need to make the ServletContext an static member of the class. What other ways exist of setting conf params at deployment time and what are the recommended ones?

  • android Convert phone number in International Format

    - by Arutha
    I'd like to know whether it's possible to have phone numbers converted into international format when a call is outgoing. For instance, if a french user (sorry it's the only format i know i won't make a mistake :-) try to call with the national format : 01.47.12.34.56 then a method will convert it into international format like this : +33.1.47.12.34.56 I've looked into the doc of the PhoneNumberUtils but i don't know if there is a method doing what i want.

    - by Jared
    I've created a custom control that subclasses TreeView. Right now it's completely empty, doesn't override anything. However when I place an instance in the designer the 'Auto' value for the Width and Height fields is no longer available as it is with the default TreeView. What am I missing?

  • Add subview to another view

    - by Martol1ni
    With two ViewControllers, MyView 1 and MyView 2, is there possible to add a subview to MyView2 from MyView1.m? I have tried: MyView2 * screen = [[MyView2 alloc]initWithNibName:nil bundle:nil]; [screen.view addSubView:mySubView]; But my new instance of MyView 2 has no connection to the 'visible' ViewController on MyView2, right? To clarify, the ViewController that is showing, is MyView1. I want MyView1 to be able to add a subview to the MyView2 view. Thanks
