如何在表视图中为ios中的联系人实施search栏
我在viewdidload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]; 代码实施search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];
表视图的代码
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;
我怎样才能在故事板的联系人的表视图中实现search栏？我是新来的iOS？ 以及如何在表视图内实现加button和点button？
Devi我完整的答案。它完美的作品。我使用search栏。也使用委托方法。

打印结果对于联系人
The contactsArray are - ( "John Appleseed", "Kate Bell", "Anna Haro", "Daniel Higgins", "David Taylor", "Hank Zakroff" )
请参阅下面的链接，我可以使用这个在表格视图中实现search栏。
