我有以下UITableViewController
+ UISearchBar
设置
@interface FeedTableView : UITableViewController <UISearchBarDelegate,UISearchDisplayDelegate>
{
NSMutableArray *ArrayDatiOriginali;
NSMutableArray *searchData;
UISearchBar *searchBar;
UISearchDisplayController *searchDisplayController;
}
在加载方法
下面- (void)viewDidLoad
{
[super viewDidLoad];
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
searchDisplayController.delegate = self;
searchDisplayController.searchResultsDataSource = self;
searchDisplayController.searchResultsDelegate=self;
self.tableView.tableHeaderView = searchBar; tableView.
}
要在出现UISeach时选择数据/行,请使用
if(tableView==self.searchDisplayController.searchResultsTableView)
{
NSLog(@"Riga corrente: %i",indexPath.row);
appo=[searchData objectAtIndex:indexPath.row];
}
并且可以过滤表视图。
但是如果:
然后
didSelectRowAtIndexPath
被解雇,但在cellForRowAtIndexPath
方法中的表达式
if(tableView == self.searchDisplayController.searchResultsTableView)返回FALSE
如果UISearchView
处于有效状态
有什么想法吗?

制作两个阵列。
dataArray
&amp; filteredDataArray
&安培;将BOOL设为已过滤。
-(void)searchBar:(UISearchBar*)searchBar textDidChange:(NSString*)text
{
if(text.length == 0)
{
isFiltered = FALSE;
}
else
{
isFiltered = true;
}
[self.tableView reloadData];
}
- (void)searchBarCancelButtonClicked:(UISearchBar *) searchBar
{
isFiltered = FALSE;
[searchBar resignFirstResponder];
[self.tableView reloadData];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(isFiltered)
{
<#YOUR_MODEL#>= [filteredDataArray objectAtIndex:indexPath.row];
}
else
{
<#YOUR_MODEL#>= [dataArray objectAtIndex:indexPath.row];
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
int rowCount;
if(isFiltered)
rowCount = [filteredDataArray count];
else
rowCount = [dataArray count];
return rowCount;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// [tableView deselectRowAtIndexPath:indexPath animated:YES];
if(isFiltered)
{
<#YOUR_MODEL#>= [filteredDataArray objectAtIndex:indexPath.row];
}
else
{
<#YOUR_MODEL#>= [dataArray objectAtIndex:indexPath.row];
}
//Pass it to any class or do what ever.
}

要添加到上一个答案,您还需要添加:
searchBar.delegate = self;
然后,searchBar可以调用
-(void)searchBar:(UISearchBar*)searchBar textDidChange:(NSString*)text
