如何Impliment搜索栏表视图在IOS

Question

我已经在viewDidLoad中下面的代码

totalstring=[[NSMutableArray alloc]initWithObjects:@"a",@"b",@"c",@"d",@"e",@"f",@"g",@"h",@"i",@"j",@"k",@"l",@"m",@"n",@"n",@"o",@"p",@"q",@"r",@"s",@"s",@"t",@"u",@"v",@"w",@"x",@"y",@"z", nil]; 





indid=indidvalue1; 

NSLog(@"the ind id value is %@",indid); 

serviceCall=[[Services alloc]init]; 

NSString *contactsDisplay1=@"ContactDetails"; 

NSDictionary *contactsDisplayDetails1 =@{@"IND_ID":indid}; 

[serviceCall ContactsDisplayUrl:contactsDisplay1 ContactsDisplayDetails:contactsDisplayDetails1]; 
[serviceCall setDelegate:self]; 

代码implimenting搜索栏

{ 


    filteredstring =[[NSMutableArray alloc]init]; 

    for (NSString *str in totalstring) 
    { 

    NSRange stringrange =[str rangeOfString:searchText options:NSCaseInsensitiveSearch]; 

     if(stringrange.location!= NSNotFound) 
     { 
      [filteredstring addObject:str]; 
     } 
    } 
} 
[tableView reloadData]; 

码表视图联系

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]; 

if (cell == nil) 
{ 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleTableIdentifier]; 
} 
if (tableView == self.searchDisplayController.searchResultsTableView) 
{ 
    cell.textLabel.text = [searchResultsArray objectAtIndex:indexPath.row]; 
} else 
{ 
    UIFont *myfont=[UIFont fontWithName:@"Arial" size:35]; 
    cell.textLabel.text = [contactNameSplitDisplayArray objectAtIndex:indexPath.row]; 
    cell.detailTextLabel.text=[relationTypeSplitDisplayArray objectAtIndex:indexPath.row]; 
    cell.textLabel.font=myfont; 
} 
return cell; 

如何在故事板中的联系人的表视图中实现搜索栏？我是iOS 的新手？ 以及如何在表视图中实现加按钮和点按钮？

德维我的完整answer.It工作perfectly.I使用搜索bar.Also使用该委托的方法。

ViewController.h

#import <UIKit/UIKit.h>
