iphone - Random image display using rand() -


I'm just SDK and trying to learn Objesi 2, hatred around with little apps.

Im trying to display an image randomly and I find different ways to display a picture. I have uploaded the image to the SDK resource folder.

Anyway, this is my code, can someone run me in the right direction. 

  #import "randomViewController.h" @implementation randomViewController // is not sure that it really is the right way to do this is NSArray * comImage = [NSArray arrayWithObjects: [UIImage imageNamed: @ "rock .png "], [UIImage imageNamed: @" paper.png "], [UIImage imageNamed: @" scissors.png "], zero]; - (IBAction) Randton {int text = rand ()% 3; Switch (text) {case 0: textView.text = @ "rock"; break; Case 1: textView.text = @ "Paper"; break; Case 2: textView.text = @ "" Scissor "; break; default: brake;}}

I it would like: 

  NSArray * myImageNames = [NSArray arrayWithObjects: @ "rock.png", @ "paper.png", @ "scissors.png", zero ]; Int index = arc4random ()% [myImageNames count]; UIImage * myImage = [UIImage image named: [myImageNames Objektaetindaks: Index]]; MyUIImageView.image = myImage;

of course You can keep your INGJnames so that you do not have to fix it every single run.

Edit:
see it was updated code assumes that you have already UIImageView to myUIImageView is added to your scene. I believe that that is how you got UIButton on screen before.

< p> to add a UIImageView:

announce UIImageView * myUIImageView in its header. it Deedlod using you xib that you feel in your view: 

  MyUIImageView = [[UIImageView alloc] initWithFrame: CGRectMake (X, Y, width, height)]; [Self.view addSubview: myUIImageView];

Replace x, y, width, and height with appropriate values ​​They will determine where UIImageView appears and how big it is.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. 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...
