Tapping on image i m getting EXC_BAD_ACCESS - iphone

Question

Guys, i thought i found the solution but no.... i making app cont. from past 16 hrs, may be that's y my empty mind is not making any good sound... plz help me..
I am setting Tag to my dynamically generated imageviews and setting tapgestureReconizers on that,tags are given to UITapGestureRecognizer, i want to perform different actions on click on different images, but when ever click on any image it says very silently... :| EXC_BAD_ACCESS.
Code: -
#import <UIKit/UIKit.h>
#class AppDelegate_iPhone,Litofinter,ParsingViewController;
#interface FirstViewController : UIViewController<UIGestureRecognizerDelegate>{
NSMutableArray *array;
NSString *logoString;
AppDelegate_iPhone *appDelegate;
ParsingViewController *obj;
UIScrollView *scrollView;
NSMutableArray *idArray;
}
#property (nonatomic,retain)UIScrollView *scrollView;
-(void)onTapImage:(UITapGestureRecognizer *)recognizer;
#end
#import "FirstViewController.h"
#import "AppDelegate_iPhone.h"
#import "Litofinter.h"

#synthesize scrollView;

if(self == [super init]){
obj = [[ParsingViewController alloc] init];
array = [[NSArray alloc] initWithArray: obj.LogoMutableArray];
}
return self;

This could be due to you trying to log an int as a string in your -(void)onTapImage:(UITapGestureRecognizer *)recognizer selector:
NSLog(#"Tapped Image tag: %#", recognizer.view.tag);
instead, replace %# with %i:
NSLog(#"Tapped Image tag: %i", recognizer.view.tag);
