You also cannot put a "C" array as a property. When you declare your "C" arry, you are creating a pointer to integer and setting aside some area of memory.</p> <p>Have you looked into the Objective C array classes: NSArray and NSMutableArray? You can put a pointer to an NSArray (or NSMutableArray) as an instance variable and create and initialize an array object in your init method for example.</p> <p>Here is some stuff to help:</p> <p><a href="http://www.gnustep.it/nicola/Tutorials/BasicClasses/node8.html" rel="nofollow">http://www.gnustep.it/nicola/Tutorials/BasicClasses/node8.html</a><br /> <a href="http://icodeblog.com/2009/08/26/objective-c-tutorial-nsarray/" rel="nofollow">http://icodeblog.com/2009/08/26/objective-c-tutorial-nsarray/</a></p> <p>Also, a google search on NSArray will help.</p> <p>Now I know that you want a 2X2 array, but remember, this is really stored in flat memory anyway, keep this in mind. </p> http://www.cocos2d-iphone.org/forum/topic/9377#post-54121 Tue, 07 Sep 2010 19:53:29 +0000 Benihana 54121@http://www.cocos2d-iphone.org/forum/ <p><a href="http://stackoverflow.com/questions/912016/declaring-properties-synthesizing-and-implementing-int-array-in-objective-c" rel="nofollow">http://stackoverflow.com/questions/912016/declaring-properties-synthesizing-and-implementing-int-array-in-objective-c</a><br /> <a href="http://www.iphonedevsdk.com/forum/iphone-sdk-development/10042-possible-have-array-property.html" rel="nofollow">http://www.iphonedevsdk.com/forum/iphone-sdk-development/10042-possible-have-array-property.html</a> </p> http://www.cocos2d-iphone.org/forum/topic/9377#post-54108 Tue, 07 Sep 2010 17:54:42 +0000 code206 54108@http://www.cocos2d-iphone.org/forum/ <p>I'm trying to create a drag and drop feature in my app and I need to have a way to tell the drag and drop object where the snap points and default locations are for it so I can reuse it. </p> <p>In order to do this I need to be able to set the values of an array in the object.

Here's my test code I just dropped into a project to make sure it worked as anticipated:</p> <pre><code>NSString *reqSysVer = @&quot;4.0.2&quot;; NSString *currSysVer = [[UIDevice currentDevice] systemVersion]; if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending) { NSLog(@&quot;Struck on the if statement.&quot;); } else { NSLog(@&quot;Struck on the else statement.&quot;); }</code></pre> <p>I'm running on OS 4.0.2. The above code will pass into the if statement when I run it. If I put a lower reqSysVer version number (3.0, 2.1, etc), it will also pass into the if statement, since it will meet the minimum requirement. If I put a higher number than the OS I'm running (like 4.1), the routine will drop into the else statement, since my OS failed to meet the minimum requirements. </p> <p>So in place of the NSLogs, you can set your BOOL value based on your requirements. (if = PASS, else = FAIL) </p> http://www.cocos2d-iphone.org/forum/topic/9331#post-53839 Mon, 06 Sep 2010 03:22:48 +0000 finder39 53839@http://www.cocos2d-iphone.org/forum/ <p>will that work for just 4.1 or 4.1 and above?? </p> http://www.cocos2d-iphone.org/forum/topic/9331#post-53836 Mon, 06 Sep 2010 02:38:39 +0000 Dragyn 53836@http://www.cocos2d-iphone.org/forum/ <p>In the code posted in the StackOverflow thread (copied here for clarity):</p> <pre><code>NSString *reqSysVer = @&quot;3.1&quot;; NSString *currSysVer = [[UIDevice currentDevice] systemVersion]; if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending) { //Do some clever stuff }</code></pre> <p>you would replace the @"3.1" in the reqSysVer with your requirement @"4.1". Then, inside the if statement (in place of the "Do Some Clever Stuff" comment, you would either perform your code that requires a minimum of iOS 4.1, OR you could use this spot to set a global BOOL for your app (isVersionOK), and use that to be evaluated later.</p> <p>From your code sample (assuming the use of the BOOL isVersionOK), it would look like:</p> <pre><code>if ([[UIScreen mainScreen] scale] == 2.0 &amp;&amp; isVersionOK) { bg.scale = 0.5; }</code></pre> <p>As a side note, are you serious that you can't do scaling without iOS 4.1?

I'm assuming that you're not doing anything funky like that (at least not directly). This is defiinitely NOT a typical error you see in XCode.</p> <p>What version of XCode are you using?

They only happen randomly from time to time and the only way it seems to fix them is to go to an old version of the project that I take off my Time Machine and retyping all my changes. I retype all the new stuff exactly the same and then the errors are not there.</p> <p>a couple notes.<br /> 1. it is only on ad-hoc build, not on debug build<br /> 2. if I retype the same code again from a time machine backup of it, it works as long as i don't copy/paste.<br /> 3. I am generally pissed off about it since it is so much work to fix.<br /> 4. It makes it impossible for me to work in debug mode since when i switch back to ad-hoc to send to my beta testers i have to RECODE EVERYTHING<br /> 5.
