Custom annotation/callout button no action

rhystowey · February 2011

Hey, I am new to iPhone development and am having trouble assigning a action to a custom annotation. I want to have multiple annotations/callouts with buttons to show different information in a Detail View. The pins show with the buttons but don't do anything. Here is the code I have:

mapkitDemoAppDelegate.h

@interface mapkitDemoAppDelegate : NSObject <UIApplicationDelegate> {
    
    UIWindow *window;
    UITabBarController *navigationController;	
	IBOutlet UITabBarController*  myTabBarController;
	
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController *navigationController;

@end

mapkitDemoAppDelegate.m


#import \"mapkitDemoAppDelegate.h\"



@implementation mapkitDemoAppDelegate

@synthesize window;
@synthesize navigationController;


#pragma mark -
#pragma mark Application lifecycle

- (void)applicationDidFinishLaunching:(UIApplication *)application {    
    
    // Override point for customization after app launch    
	
	[window addSubview:[myTabBarController view]];
    [window makeKeyAndVisible];
	
}


- (void)applicationWillTerminate:(UIApplication *)application {
	// Save data if appropriate
}


#pragma mark -
#pragma mark Memory management

- (void)dealloc {
	[navigationController release];
	[window release];
	[super dealloc];
}

@end

mapViewController.h


#import \"mapkitDemoAppDelegate.h\"


@implementation mapkitDemoAppDelegate

@synthesize window;
@synthesize navigationController;


#pragma mark -
#pragma mark Application lifecycle

- (void)applicationDidFinishLaunching:(UIApplication *)application {    
    
    // Override point for customization after app launch    
	
	[window addSubview:[myTabBarController view]];
    [window makeKeyAndVisible];
	
}


- (void)applicationWillTerminate:(UIApplication *)application {
	// Save data if appropriate
}


#pragma mark -
#pragma mark Memory management

- (void)dealloc {
	[navigationController release];
	[window release];
	[super dealloc];
}


@end

	return mSubTitle;
}

}


-(id)initWithCoordinate:(CLLocationCoordinate2D) c{

Please help fix my problem and just to remind you, I am new at iPhone developing so I'm a little slow. Thank you.
