POSet value of property in main view controller from dynamically instantiated class (objective-c)

Body
copied!<p>I am totally out of ideas on this... I've tried so many variations that I am dizzy...</p> <p>I have a main UIViewController which, at the touch of a button, adds another UIViewController to one of its subviews. When the dynamic UIVC gets added, a property in the main UIVC is updated to hold a reference to it (called currentObject). This is working fine.</p> <p>The problem I am having is that if I add another dynamic UIVC, the property holding the reference is initially updated correctly, but no matter what I try, I can't get the property to update when I touch the first dynamic UIVC. Everything I try to set "currentObject" from a dynamic UIVC gives me an "unrecognized selector sent to class" error and then bails.</p> <p>I'm holding off from putting code into this post at first. Not sure what I would post that would be helpful.</p> <p>Thanks in advance!</p> <p>Updated:</p> <p>in DynamicModuleViewController.h:</p> <pre><code>@interface DynamicModuleViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIPopoverControllerDelegate, UIGestureRecognizerDelegate, UITextViewDelegate, UIApplicationDelegate, MFMailComposeViewControllerDelegate>{ DynamicModule *currentObject; } @property(nonatomic, retain) DynamicModule *currentObject; </code></pre> <p>in DynamicModuleViewController.m:</p> <pre><code>@implementation DynamicModuleViewController @synthesize currentObject; -(void)addObject:(id)sender { DynamicModule *dm = [[DynamicModule alloc]init]; // positioning and PanGesture recognition code to allow dragging of module currentObject = dm; [mainView addSubview:currentObject.view]; } @end </code></pre> <p>when added this way, from a button tap, it works fine. </p> <p>Once more DynamicModules are instantiated, I need to update currentObject with the DynamicModule that was tapped last.</p>
