What I'm trying to do is to sort a list of MyClass objects depending on my Datatype object different search functions should be used. I've had something like this in mind for the class Da...
Hi, I'm having a problem with a checkbox. I want to set it to 0 (unchecked) on app launch, but the checkbox is controlled by another class "myClass" for example. Here's what I did: I opened Interface Builder and put a checkbox (NSButton) in my window, dragged NSObject in my MainMenu.xib window, renamed it to say "myClass". Added an o...
Hi all, I'm puzzling over how multithreading can work with delegates. The main thread has an object "A", which has created an object "B". Object "A" is the delegate for object "B". Object "B" uses a thread to run the code. When object "B" wants to notify the delegate, it does: [[self delegate] performSelectorOnMainThread:@selector(di...
This is more of a C# syntax question rather than an actual problem that needs solving. Say I have a method that takes a delegate as parameter. Let's say I have the following methods defined: void TakeSomeDelegates(Action<int> action, Func<float, Foo, Bar, string> func) { // Do something exciting } void FirstAction(int arg) { /* som...
Like many people, I have a splash screen that animates off to reveal the first view of my app. I've been reworking this for the iPad and if you are holding the device in portrait or landscape modes, everything works as intended, the correct default image is used, the correct image that is used to animate this off is used, all orientation...

Hi all, I've been using the jQuery templates code (jquery.tmpl.js on github) and it's been working very well for me. However, I'm trying to attach events to the content using delegate and it's not working. Here is my simplified HTML structure after the templates are inserted: <!-- static in the html file --> <div id="container"> <!--...
I have three textfields in interface builder being used to accept input. When a button is pushed the data in the 3 fields are processed. Currently, when one of the textfields sends out a textFieldShouldReturn (or similar) message to its delegate, I assign the "sender" parameter (using the tag property) to the delegate's respective UIText...
I'm working with a bit of code that is structured thusly: Form A has user controls B and G within it. User control B has User control D within it, and user control D has a "refresh" method. User control G has user control F within it, and user control F needs to call the "refresh" method in D. 1) Short of restructuring the code (It's l...

We have the following hierarchy: UIViewController -> UIScrollView (custom subclass) -> UIView (custom subclass) We are presenting a grid of buttons that are dynamically generated. When a user taps one of the UIViews that belong to the custom scroll view we fire a method that looks lik...
In using .NET asynchronous delegates for the first time, I was surprised to empirically discover that when changing an instance member value (e.g. an int) in the asynch method (running in the new thread), the value of the instance member running in the original thread was also changed. I thought that when a new thread is created, instan...
I have a simple project to present a modal view controller and transfer back a string based on which button in the modal VC that gets pressed. I based it all on watching the Stanford class on iTunes U. It looks like I have everything correct, but I get a couple of compiler warnings. First I get one called passing argument 1 of 'setDel...
Hi everyone, We'd like to track who's on our website and what pages they're looking at. The plan is to create a delegate (which will log visits to a database table) and call it asynchronously. We're using .Net 3.5 and I don't know if the delegate idea, along with BeginInvoke and EndInvoke, is the way to go these days or if there are...
I created an object that has specific method to process different kind of events and will lived until my application is running. I also created individual delegates pointing to each methods and are referenced to x number of threads. Given y and z thread will invoke method1 by using a delegate pointing to it, will z thread wait for y thr...

The UI will have to start a separate thread for the routine in the class library that will be polling The class library will then need to trigger a callback function in the UI to update ...
