objective c - Is this combination of inheritance and protocols correct? -


In this scenario, I want a class whose purpose is to direct some subclases, keeping in mind the need for implementation of the original class Base behavior I thought:

Protocol 

  @protocol TheProtocol @required - (NSString *) Some properties; - (zero) Some method: (NSString *) parameter;

Base view controller 

  @interface BaseViewController: UIViewController @end @implementation BaseViewController - (zero) viewDidLoad { Super Viewedload]; NSSart ([Self Conflict Protocol: @ Protocol (The Protocol)], @ "This view controller has to be compatible with TheProtocol."); } - (Zero) ViewVillagePower: (BOOL) Animated {[Super Viewer: Animated]; BaseViewController & LT; TheProtocol & gt; * CastedController = (BaseViewController & lt; theProtocol & gt; *) itself; NSString * Some Properties = [Some Developers Property]; NSLog (@ "% @", some properties); [Caste Communicator Some Method: @ "Hello Subclasses!"]; }
TheProtocol & gt; @end @ Implementation Subclass 1View Controller # Prima Mark - The Protocol - (nssting *) Some Properties {Return @ "Subclass 1"; } - (zero) Some method: (NSString *) parameter {NSLog (@ "% @", parameter); } @end

Is this pattern correct? I have many concerns ... the other option is to create a safe category rather than a protocol.

Your pattern is correct.

Here's a similar solution to your idea, but personally I will do this in my project for the same purpose - so I do not have to put an example of this in. BaseClass < / Code>, because in my opinion the base class corresponds to essentially DemandedProtocol , but throws a runtime exception in every required method does not override in the subset but they To apply I tried it

Note: This is not worse or better than you, but differently, someone can use it for educational purposes in the future.

The requested protocol. 

  @protocolprogram requested & lt; NSObject & gt; @required - (NSString *) someString; - (zero) set something: (id) something; @optional - (ntiiittaar) some integer; @end

BaseClass.h 

  #import "Demand Protocol" #define ThrowOverrideIsMissingException @throw [NSException with Exceptionname: NSInternalInconsistencyException Reason: [NSString stringWithFormat: @ "% S is to be overridden in subsets.", __func__] userInfo: zero] @ interface base class: NSObject & lt; DemandedProtocol & gt; {} @end

base class.m 

  #import "BaseClass.h" @ Implementation Base Class # Pragya Mark - & lt; Demanded prototol & gt; - (NSString *) Some strings {ThrowOverrideIsMissingException; } - Set something (zero): (id) some {ThrowOverrideIsMissingException; } @end

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title '). CSS (' font-size ')) + 1 + "pixels"); } While (parasont ($ ('# text'). Css ('font-size')) & lt; = 100) {sleep (1000); IncreaseSize (); Using CSS: Use of jQuery (sample):
