• Display different iphone views depending on logged in status

  - by user330936

  I want to display a login view to my users if they are not logged in and the main view if they are. In my header file I define a variable to hold the logged in status #define loggedIn 0 I figure I should then reference this in the initWithNibName method and then decide which nib to load.

• UIView viewWithTag 0 problem

  - by leon

  Hi, On view in IB I have numerous items (including view itself). ONLY one item has tag 0, yet following line works for ANY UITextBox other then the one with tag 0. Note that only ONE UITextBox has tag 0, why: (UITextField *) [self.view viewWithTag:0]).text = @"foo"; Interesting that when triggered event received for the element with tag 0, I can get value of Tag 0 with no problem. Is there a limitation to look for tag 0 elements?

• How to override 'where' in rails 3

  - by Zakwan Alhajjar

  I have upgraded my application from rails 2.3.8 to 3.0.3 . But I'm facing a problem. I was using 'find' but the overriding doesn't work in rails 3: # override activerecord's find to allow us to find by name or id transparently def self.find(*args) if args.is_a?(Array) and args.first.is_a?(String) and (args.first.index(/[a-zA-Z\-_]+/) or args.first.to_i.eql?(0) ) find_by_login_slug(args) else super end end I'm wondering if there is a way to make this work in rails 3 or even by using where instead. thanks

• What hash/map based programming language exist?

  - by Davorak

  Much like lisp is often considered a list based programming language what languages are considered map based? I remember reading about one a few years back, but can not longer find a reference to it. It looked something like: [if:test then:<code> else:<more code>] edit: and more where quoted code blocks which would be conditional evaluated. In this fashion if/cond and others would not be special form as they are in lisp/scheme.

• referencing desired objects in namespaced functions

  - by RyOnLife

  I'm having trouble referencing the desired object when I've namespaced functions. No problems here: obj.test = function() { // this == obj } But I'm getting tripped up when I namespace: obj.namespace.test = function() { // this == namespace } In the latter example, I know this references namespace, but I want to reference obj. How can I do it?

• closure not working

  - by dorelal

  var Dog = function() { var _instance = 'hello world'; return function() { console.log(this._instance); } } (); //note that it is self invoking function var l = new Dog(); //#> undefined In the above case I was expecting output of 'hello world'. Why this._instance is not accessing the the varible which should be accessible by virtue of closure. I tested this in FF and am getting undefined.
