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
Code:
@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
Code:
#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
Code:
#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.m
Code:
#import "mapViewController.h"
#import "mapkitDemoAppDelegate.h"
#import <CoreLocation/CoreLocation.h>
@implementation GPSAnnotation
@synthesize coordinate;
@synthesize mTitle;
@synthesize mSubTitle;
@synthesize currentPoint;
- (NSString *)subtitle{
return mSubTitle;
}
- (NSString *)title{
return mTitle;
}
-(id)initWithCoordinate:(CLLocationCoordinate2D) c{
coordinate=c;
NSLog(@"%f,%f",c.latitude,c.longitude);
return self;
}
@end

Please help fix my problem and just to remind you, I am new at iPhone developing so I'm a little slow. Thank you.
Custom annotation/callout button no action
Linear Mode
