imageView= [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"KK_Map-02.jpg"]];
//self.imageView = imageView;
//[tempImageView release];

[super viewDidLoad];
//aWw.delegate = self;
//[scrollView setUserInteractionEnabled:YES];
scrollView.contentSize = CGSizeMake(imageView.frame.size.width, imageView.frame.size.height);//imageView.frame.size.width*9.6, imageView.frame.size.height*0.9

//scrollView.contentOffset = CGPointMake(imageView.frame.size.width/4,
// imageView.frame.size.height/4);


//CGRect rect = CGRectMake(119, 42, 208, 166);

scrollView.maximumZoomScale = 4.0;
scrollView.minimumZoomScale = 0.33;
scrollView.clipsToBounds = YES;
scrollView.delegate = self;
scrollView.bouncesZoom=FALSE;




[scrollView addSubview:imageView];


float minimumScale = [scrollView frame].size.width / [imageView frame].size.width;
[scrollView setMinimumZoomScale:minimumScale];
[scrollView setZoomScale:minimumScale];

JS to Obj-c and Objc to JS

search for text which you can to test against

- (BOOL)webView:(UIWebView *)localwebView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {

NSURL *url = [request URL];

NSString *path = [[request URL] path];

NSString *pathTrimmed = [path lastPathComponent];

NSLog(@"sfdf %@",url);

NSLog(@"path f %@",pathTrimmed);

if ([pathTrimmed isEqualToString:@"Reset"]) {

// Display alert
UIAlertView *alertb = [[UIAlertView alloc] initWithTitle:@"You want to Reset Data??" message:@"" delegate:self cancelButtonTitle:@"No" otherButtonTitles: @"YES",nil];
alertb.tag=3;
[alertb show];

[alertb release];
return NO;
}
return YES;


}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {


if(buttonIndex == 1) {

//NSLog(@" its done now uplaod data");
[localwebView stringByEvaluatingJavaScriptFromString:@"confirmation()"];
