Answer 1

Declare in .h file:
BOOL isFiltered;
NSMutableArray *arrsearchresult ,*arrsearchname;
NSMutableArray *arrfullname;
#property (strong, nonatomic) IBOutlet UITableView *tblAppoinment;
Declare in .m file:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
/*if (tableView == self.searchDisplayController.searchResultsTableView) {
return [arrsearchresult count];
} else {
return [arrfullname count];
}*/
if(isFiltered)
{
return [arrsearchresult count];
}
return [arrfullname count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableCell";
AppoinmentTableViewCell *cell = (AppoinmentTableViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"AppoinmentTableViewCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
if(isFiltered)
{
cell.lblFullname.text = [arrsearchresult objectAtIndex:indexPath.row];
}
}
if(isFiltered)
{
cell.lblFullname.text = [arrsearchname objectAtIndex:indexPath.row];
}
}
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {
isFiltered = YES;
}
- (void) searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
if(searchText.length==0)
{
isFiltered=NO;
}
else
{
isFiltered=YES;
arrsearchresult=[[NSMutableArray alloc]init];
arrsearchdate=[[NSMutableArray alloc]init];
arrsearchname=[[NSMutableArray alloc]init];
for ( NSString * str in arrfullname)
{
NSRange stringRange = [str rangeOfString:searchText options:NSCaseInsensitiveSearch];
NSInteger index;
if(stringRange.location != NSNotFound)
{
[arrsearchresult addObject:str];
index = [arrfullname indexOfObject:str];
[arrsearchdate addObject:[arrleadCreatedDate objectAtIndex:index]];
[arrsearchname addObject:str];
}
}
}
[self.tblAppoinment reloadData];
}
-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{
[self.tblAppoinment resignFirstResponder];
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
isFiltered=NO;
[self.tblAppoinment reloadData];
}

Answer 2

Though you are talking about search bar. but according to your requirement, it's better to use Search Controller than search bar standalone. Because there are many delegates method you will find along with these.So you don't have to take headache for extra effort.

Answer 3

This code is for filter array.
- (BOOL)searchBar:(UISearchBar *)searchBar shouldChangeTextInRange:
(NSRange)range replacementText:(NSString *)text
{
NSArray *resultarray;
NSString *strSearch = [NSString stringWithFormat:#"%#",searchB.text];
if ([strSearch isEqualToString:#""])
{
[self showAllData];
return;
}
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"self CONTAINS[cd] %#",strSearch];
resultarray = [self.arrayALLData filteredArrayUsingPredicate:predicate];
[self.arrayPeopleList removeAllObjects];
[self.arrayPeopleList addObjectsFromArray:resultarray];
[_tblView reloadData];
return YES;
}
