   NSURL *url = [NSURL URLWithString:urlString];
   NSLog(@"************url:%@",url);

    NSURLRequest *theRequest=[NSURLRequest requestWithURL:url
                                   cachePolicy:NSURLRequestUseProtocolCachePolicy
                                timeoutInterval:60.0];
   NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
   if (theConnection) {
      webData = [[NSMutableData data] retain];
      NSLog(@"%@",webData);
   } else {

   }   

}

make your url properly like this:-

NSURL *url = [NSURL URLWithString:[*yourstring* stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

Harish this will help u to in creating the url check this our http://wiki.akosma.com/IPhone_URL_Schemes like this

 NSString *template = @"appigotodo://com.example.xyzapp/import?name=%@&note=%@&due-date=%@&priority=%@&repeat=%@";
NSString *name = @"Buy%20some%20milk";
NSString *note = @"Stop%20on%20the%20way%20home%20from%20work.";
NSString *dueDate = @"2009-07-16";
NSString *priority = @"1";
NSString *repeat = @"101";
NSString *stringURL = [NSString stringWithFormat:template, name, note, dueDate, priority, repeat];
NSURL *url = [NSURL URLWithString:stringURL];

[[UIApplication sharedApplication] openURL:url];

Two things:

1. The URL has many % symbols that are not being used as placeholders. The % symbols that are not between '**' in your code need to be escaped like so: %%. In other words, SearchInputFRSearchView%24Button should be SearchInputFRSearchView%%24Button.

2. You are using %i to put integers into your string. You should be using %d instead.
