    text
    copied!<p>I am having trouble accessing an int property from another class. I know this question has been asked quite a few times however none of the solutions posted in previous questions seem to work. My knowledge in xcode is basic, and I am using this project to develop my skills.</p> <p>The two classes I have are: HelloWorldLayer and ClassOne. Where ClassOne states the value of int. Both are Cocos2d CCLayer classes (probably not the best class to practice inter-class value access).</p> <p><strong>ClassOne.h</strong></p> <pre><code>@interface ClassOne : CCLayer { int ageClass; } @property (nonatomic, readwrite)int ageClass; @end </code></pre> <p><strong>ClassOne.m</strong></p> <pre><code>@implementation ClassOne @synthesize ageClass = _ageClass; -(id)init{ if((self=[super init])){ _ageClass = 10; } return self; } @end </code></pre> <p><strong>HelloWorldLayer.h</strong></p> <pre><code>#import "ClassOne.h" @interface HelloWorldLayer : CCLayer &lt;...&gt; { ClassOne *agePointer; } @property (nonatomic,assign)ClassOne *agePointer; +(CCScene*)scene; @end </code></pre> <p><strong>HelloWorldLayer.m</strong></p> <pre><code>#import "HelloWorldLayer.h" #import "AppDelegate.h" #import "ClassOne.h" @implementation HelloWorldLayer @synthesize agePointer = _agePointer; +(CCScene*)scene... -(id)init{ if((self=[super init])){ _agePointer.ageClass = self; NSLog(@"ClassOne int = %@",_agePointer); } return self; } ... @end </code></pre> <p><strong>Output Result:</strong></p> <pre><code>"ClassOne int = (null)" or "0" if i use "%d" token and "int = x", where the line "int x =_agePointer.ageClass;" is used. </code></pre> <p>The result I am after is for the HelloWorldLayer NSLog to display "10", the int value defined in ClassOne.</p> <p>Any wisdom and corrections on my use of language is greatly appreciated.</p>
