As well as the name of the product that the user has clicked on. How can I do this? ViewModel public class ProductViewModel { public ProductViewModel() { products = new List

问题 I'm trying to understand the implementation of the MVC-Pattern in iOS Apps with Objective-C. Right now I have a DataProvider object which holds and provides my data to other objects in my application (Model). Furthermore I have a View (.xib) with an additional class ( UIView ; lets call it "ViewClass"). I told my view to be a subclass of my ViewClass so that I'm able to create IBOutlet s to my subviews like labels and IBAction s to my buttons. So this is obviously my View in the MVC-Pattern.

问题 I have a text label on view 1 and a button. If I click the button, I am brought to view 2 through a modal connection. In this view, I enter a number and press a button. The button saves the number to NSUserDefaults, as well as tries to update the text label on view 1 to reflect this number. Button's code: - (IBAction)returnToView1:(UIButton *)sender { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; defaults setObject:@"myNumber" forKey:@"myKey"]; [defaults synchronize];

问题 I am writing a piece of software where my user should be able to add data to a table-like editing widget, which I managed to render by using a GtkTreeView . I was able to render my cell editable by setting its editable property via this call g_object_set(content_renderer, "editable", TRUE, NULL); However, my GtkTreeView not only doesn't retain values entered as it's not even showing the data I've added before rendering. I saw a few examples in the web where the developer manually set the user

问题 I have a question regarding Visual Studio 2010 publish feature which is used after you create a website (MVC framework) to push your dev changes to the live site. I've never worked with MVC until a few weeks ago and I've noticed that before pushing the website code I have to change everywhere where I have localhost in the code and replace it with the domain name I'm pushing to. Then if I want to debug anything on my local machine I have to revert everything back to localhost from domain name.

问题 Basically there is two options as I know. The first is view expose notifications events which a presenter should be subscribed to. When user clicks on some button on the view, view just triggers some event, notifies that something is changed. The second is just use an observer pattern and let the presenter interfere some contract. Let it be an interface with methods like events I told you above. An presenter-observer should be attached to the view. As Jeremy Miller in his legendary "Build
