How to access @public instance variable from another class in Objective-C? -


I know that it is possible to define a public public word @with the public keyword, however, Objective-C syntax Does not allow access to other class' variables. @What facilities do I want from public Ivar? Or how can I use other class Ivars?

Objective-C, definitely public from outside the implementation of class as a superset of C Allows to use the frequency variable. Now, the reason for this is that you have heard that is not allowed this is very disappointing. In most cases, if you want to access any frequency variable outside the context of an implementation, then you should use the accessories and the mute (properties).

An object-class is actually a plain-old C string with a ii field (that is, it creates an object), where public areas are accessible since we Working with examples of classrooms, we are working as an indicator for an object (special structure). In this way, we have the - & gt; You can use public areas by using .

Here is an example: 

  @interferson; Induscipling a person: NSBDIDA {@public NSString * badIdea; BOOL should notDoIt; @ Protected NSString * ahThatsBetterThankGod; @PrivateNosting * MittleTenNov and MySubsCarscentTouchMe; }

Now, in some completely different contexts, we may have: 

  Any human being encasing * What is oh = [ [Any infant encryption alok] initWithDanger: kDangerLevelEpicBraceYourself]; WhatOh-> BadIdea = [@ "I'm a public area. Make sure to keep me or copy!" Copy]; NSLog (@ "Please Write Some Accessories and Mutants !:% @", Oh-> Bad Idea);

I hope your help!

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
