I have table view and when I touch cell, detailTextLabel appears. I implemented search, but didSelectRowAtIndexPath doesn't work for search results array. I just copied the code from the cellForRowAtIndexPath.
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:#"name contains[c] %#", searchText];
self.searchResults = [self.cards filteredArrayUsingPredicate:resultPredicate];
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex:[self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:#"Card Cell" forIndexPath:indexPath];
if (tableView == self.searchDisplayController.searchResultsTableView) {
Card *card = [self.searchResults objectAtIndex:indexPath.row];
[cell.textLabel setText:[NSString stringWithFormat:#"%#", [card valueForKey:#"name"]]];
[cell.detailTextLabel setText:[NSString stringWithFormat:#"%#", [card valueForKey:#"otherSide"]]];
cell.detailTextLabel.hidden = YES;
} else {
Card *card = [self.cards objectAtIndex:indexPath.row];
[cell.textLabel setText:[NSString stringWithFormat:#"%#", [card valueForKey:#"name"]]];
[cell.detailTextLabel setText:[NSString stringWithFormat:#"%#", [card valueForKey:#"otherSide"]]];
cell.detailTextLabel.hidden = YES;
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.tableView beginUpdates];
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:#"Card Cell" forIndexPath:indexPath];
if (tableView == self.searchDisplayController.searchResultsTableView) {
Card *card = [self.searchResults objectAtIndex:indexPath.row];
[cell.textLabel setText:[NSString stringWithFormat:#"%#", [card valueForKey:#"name"]]];
[cell.detailTextLabel setText:[NSString stringWithFormat:#"%#", [card valueForKey:#"otherSide"]]];
cell.detailTextLabel.hidden = NO;
} else {
Card *card = [self.cards objectAtIndex:indexPath.row];
[cell.textLabel setText:[NSString stringWithFormat:#"%#", [card valueForKey:#"name"]]];
[cell.detailTextLabel setText:[NSString stringWithFormat:#"%#", [card valueForKey:#"otherSide"]]];
cell.detailTextLabel.hidden = NO;
}
[self.tableView endUpdates];
}
There are some notable differences between cellForRowAtIndexPath and didSelectRowAtIndexPath. cellForRowAtIndexPath creates a cell or gets a existing of the cell stack and you will enter the properties and return it before its displayed. In didSelectRowAtIndexPath you don't get that cell in the parameters, so you have to call the [tableview cellForRowAtIndexPath] instead of [self.tableView dequeueReusableCellWithIdentifier:#"Card Cell" forIndexPath:indexPath]; to get the cell and set the properties.
Also make sure you have set the delegate of the tableview.

I am new in ios and I am facing problem regarding to UISearchbar. I have done code like this
.h
IBOutlet UITableView *table;
NSArray *recipes;
NSArray *searchResults;
.m
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
recipes = [NSArray arrayWithObjects:#"Egg Benedict", #"Mushroom Risotto", #"Full Breakfast", #"Hamburger", #"Ham and Egg Sandwich", #"Creme Brelee", #"White Chocolate Donut", #"Starbucks Coffee", #"Vegetable Curry", #"Instant Noodle with Egg", #"Noodle with BBQ Pork", #"Japanese Noodle with Pork", #"Green Tea", #"Thai Shrimp Cake", #"Angry Birds Cake", #"Ham and Cheese Panini", nil];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
return [searchResults count];
} else {
return [recipes count];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
if (tableView == self.searchDisplayController.searchResultsTableView) {
cell.textLabel.text = [searchResults objectAtIndex:indexPath.row];
} else {
cell.textLabel.text = [recipes objectAtIndex:indexPath.row];
}
return cell;
}
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:#"SELF contains[cd] %#",
searchText];
searchResults = [recipes filteredArrayUsingPredicate:resultPredicate];
}
-(BOOL)searchDisplayController:(UISearchController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex:[self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}
But it shows me search bar on navigation bar
But I need to show it on the UItableView itself. Like this in Image

You should remove
[myTableView selectRowAtIndexPath:0 animated:YES scrollPosition:
UITableViewScrollPositionNone];
and use this to select the first row (this should be called once outside this method or you want to set this row selected everytime each cell is render)
[myTableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:YES scrollPosition:UITableViewScrollPositionNone];
And I don't know why you called this in this method
[myTableView.delegate tableView:myTableView didSelectRowAtIndexPath:0];
but if you want to call it you should change to this too
[myTableView.delegate tableView:myTableView didSelectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];
ps. You should set the cell's selectionStyle correctly to see the cell is selected.
Update::
Try to replace all codes in the method with this
Report_SelectGroupTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Report_SelectGroupTableViewCell"];
if (!cell){
cell = [[[NSBundle mainBundle] loadNibNamed:#"Report_SelectGroupTableViewCell" owner:self options:nil] objectAtIndex:0];
}
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
[tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:YES scrollPosition:UITableViewScrollPositionNone];
return cell;
Please tell me if the first row is not selected and highlighted.
For some reason NSPredicate isn't filtering my UITableView (it's supposed to be filtering my TableView by selections made in a UIPickerView). Users make their pickerview selections, press the GO button (segue is attached from Pickerview to Table View controller).

Very puzzling, your code actually seems ok to me. I'd start by NSLoging searchResults right after the searchResults = [Strains filteredArrayUsingPredicate:resultPredicate]; line is fired, just in case something funny is happening in the table view delegates.
You should also probably check out the free Sensible TableView framework, as it provides automatic searching and filtering for your data. Should save you a ton of time.
It seems your Strains array contains dictionaries. So you should decide on what key you want to filter, for example the Title key, instead of using SELF:
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:#"Title contains[cd] %#",
searchText];
From the pickerViewController, you need to go back to the tableViewController. You can use delegate. And try to make a separate function in the table view controller to filter which contains the predicate:
- (void)filterContentForPicker:(NSString*)searchText
{
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:#"Title contains[cd] %#",
searchText];
searchResults = [Strains filteredArrayUsingPredicate:resultPredicate];
[self.tableView reloadData]
}

The problem that you scroll your tableView when - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath method is called and you set
NSIndexPath* selection = [tableView indexPathForSelectedRow];
if (selection && selection.row == indexPath.row) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
} else {
cell.accessoryType = UITableViewCellAccessoryNone;
}
that means when you will scroll indexPath will be for the current row only so the checkmark at the current row will still checked but the all the other rows will enter the else condition and the checkmark will be removed.
To fix it you should make a do the following:
define the following property:
#property (nonatomic)BOOL isViewIsLoadedForTheFirstTime;
-(void)viewDidLoad
{
self.isViewIsLoadedForTheFirstTime = YES;
}
then replace these lines in the (cellForRow) method
if (selection && selection.row == indexPath.row) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
} else {
cell.accessoryType = UITableViewCellAccessoryNone;
}
to the following lines:
if (self.isViewIsLoadedForTheFirstTime) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
self.isViewIsLoadedForTheFirstTime = NO;
}
This will make you set the check mark only when the view loaded for the first time the when you will scroll it won't change.
I hope that will help you

guys, I have tableview, which is loading from my nsarray, but after managing cells, it shows elements in incorrect places.

NSString *commentText = [currentComment objectForKey:#"text"];
cell.textLabel.tag = 0xff ;
cell.textLabel.numberOfLines = 0;
cell.textLabel.font = [UIFont fontWithName:#"Verdana" size:17.0];
cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
cell.textLabel.text = commentText;

Have you any ideas?
You need to update your NSArray whenever you modify the cells in your table, otherwise your data source and view will get out of sync.
So whenever you call:
[tableView insertRowsAtIndexPaths:rows withRowAnimation:UITableViewRowAnimationAutomatic];
You should put
for (NSIndexPath *indexPath in rows)
{
[self.myDataArray insertObject:myRowModel atIndex:indexPath.row];
}
As well so that your view and model stay in sync.
Obviously the above is pseudocode (you'd have to create an instance of whatever your model objects are), and your array will have to be an NSMutableArray or it will crash when you try to insert into it.
