custom UISearchBar

直接添加：

UISearchBar *mySearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 45)];
         mySearchBar.delegate = self;
         mySearchBar.showsCancelButton = NO;
         mySearchBar.barStyle=UIBarStyleDefault;
         mySearchBar.placeholder=@"Enter Name or Categary";
         mySearchBar.tintColor = [UIColor colorWithRed:(247.0/255.0) green:(126.0/255) blue:(33.0/255) alpha:1.0];
         mySearchBar.keyboardType=UIKeyboardTypeNamePhonePad;
         [self.view addSubview:mySearchBar];
         [mySearchBar release];

在tableview上添加：

//add Table
        UITableView *myBeaconsTableView = [[UITableView alloc] 
                                           initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height-40) 
                                           style:UITableViewStylePlain];
        
        myBeaconsTableView.backgroundColor = [UIColor whiteColor];
        myBeaconsTableView.delegate=self;
        myBeaconsTableView.dataSource=self;
        [myBeaconsTableView setRowHeight:40];
        
        // Add searchbar 
        searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, 40)];
        searchBar.placeholder=@"Enter Name";
        searchBar.delegate = self;
        myBeaconsTableView.tableHeaderView = searchBar;
        searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
        searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
        [searchBar release];
        
        [self.view addSubview:myBeaconsTableView];
        [myBeaconsTableView release];
