I am facing strange issue with UITableViewController. I display search result in UISearchDisplayController. If I have some data in search result then it is fine, but when I have empty result it will show section of UITableView which resides behind this SearchDC. I have same delegate and source for both Search and normal table view. Refere images attached with post(one is at beginning and one at end).I have colde like below:
- (NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
NSString *pstrHeader = [[NSString alloc] init];
if(self.isSearchActivated)
{
NSInteger count = [self.parrSearchDataSourceKeys count];
if(count > 0)
pstrHeader = [pstrHeader stringByAppendingString:[self.parrSearchDataSourceKeys objectAtIndex:section]];
else
{
pstrHeader = nil;
[[[UIAlertView alloc]initWithTitle:@"header of section" message:@"Count is zero" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil] show];
}
}
else
{
NSInteger count = [self.parrDataSourceKeys count];
if(count > 0)
pstrHeader = [pstrHeader stringByAppendingString:[self.parrDataSourceKeys objectAtIndex:section]];
else
pstrHeader = nil;
}
return pstrHeader;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
//#warning Potentially incomplete method implementation.
// Return the number of sections.
NSInteger count = 0;
if(self.isSearchActivated)
{
count = [self.parrSearchDataSourceKeys count];
if(count <= 0)
{
[[[UIAlertView alloc]initWithTitle:@"number of section" message:@"Count is zero" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil] show];
}
}
else
count = [self.parrDataSourceKeys count];
return count;
}
I have same class for delegate and source but internally it will handle different maps and arrays for normal table view and search result table view.
Also I display search result like below:
-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
NSString *selectedTitle = [searchBar.scopeButtonTitles objectAtIndex: searchBar.selectedScopeButtonIndex];
selectedTitle = [self convertStringToEnglish:selectedTitle];
self.isSearchActivated = YES;
FolderInfo* searchFolder = [[FolderInfo alloc] init];
if(self.pmdSearchDataSource != nil)
{
[self.pmdSearchDataSource removeAllObjects];
}
if(self.parrSearchDataSourceKeys != nil)
{
[self.parrSearchDataSourceKeys removeAllObjects];
}
NSString* pstrSearchText = [searchBar text];
NSString* pstrSearchIn = @"Folder";
if([self.pstrWorkspaceId isEqualToString:@"-1"])
{
pstrSearchIn = @"Application";
}
else if([self.pstrFolderId isEqualToString:@"-1"])
{
pstrSearchIn = @"Project";
}
self.pmdSearchDataSource = [[NSMutableDictionary alloc] initWithDictionary:[searchFolder GetSearchListForSubElementFor:pstrSearchText InWorkspaceId:self.pstrWorkspaceId
InFolderId:self.pstrFolderId forSearchField:selectedTitle In:pstrSearchIn] copyItems:NO ];
NSArray *keys = [[self.pmdSearchDataSource allKeys] sortedArrayUsingSelector:@selector(compare:)];
self.parrSearchDataSourceKeys = [[NSMutableArray alloc] initWithArray:keys];
self.pSearchDC.searchResultsTableView.delegate = self;
self.pSearchDC.searchResultsTableView.dataSource = self;
[self.view bringSubviewToFront:self.pSearchDC.searchResultsTableView];
[self.pSearchDC.searchResultsTableView reloadData];
}
If intially normal table view have two sections visible on screen and then i move to searchResultDC it will first show blank table but after search clicked when I have no result and reload searchResultDC tableview it will show section of normal table view which is behnind this searchResultDC
I have refered post: Reloading UITableView behind UISearchDisplayController
But note that I need section in search result also and solution in above post is for case where we dont have section in search result.
Let me know if you need more information.
