UISearchBar with separate delegate - ios

Question

I'm new to iOS programming and I need your help.
I am using UIsearchbar in our app but i want to separate the delegate of it.
I want to see the Nslog that i declare everytime I typed but it's returning an error :(
Heres my code.
//HomeController.h
#import <UIKit/UIKit.h>
#import "AsyncImageView.h"
#define kBgQueue dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)
#interface HomeController : UIViewController< UIScrollViewDelegate>
#end
//HomeController.m
SearchBarDelegate *searchDelegate = [[SearchBarDelegate alloc]init];
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 20, 320, 44)];
searchBar.placeholder = #"Search here";
searchBar.layer.zPosition = 1000;
[self.view addSubview:searchBar];
searchBar setDelegate:searchDelegate];
//SearchBarDelegate.h
#import <UIKit/UIKit.h>
#interface SearchBarDelegate : UISearchBar<UISearchBarDelegate>
#end
//SearchBarDelegate.m
#import "SearchBarDelegate.h"
#implementation SearchBarDelegate
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
return self;
}
/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
// Drawing code
}
*/
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBars //Clicked the box
{
searchBars.showsCancelButton = YES;
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBars //hides searchBar and keyboard
{
searchBars.showsCancelButton = NO;
[searchBars resignFirstResponder];
}
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBars //search button in keyboard
{
[searchBars resignFirstResponder];
}
- (void) searchBar:(UISearchBar*)searchBars textDidChange:(NSString*)searchText //while typing
{
NSLog(#"Typing... -> %#",searchBars.text);
}
#end
