I want to set up a UISearchDisplayController such that after a cell is selected from the search results, the search display controller is dismissed and the table view scrolls to the selected cell. Here's my code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView == self.searchDisplayController.searchResultsTableView)
{
[self.searchDisplayController setActive:NO];
// scroll to selected cell in table view here
}
}
I know the method I need to use is:
scrollToRowAtIndexPath:atScrollPosition:animated:
However, this method needs an index path from the main table view, not the search results table view. How can I get this index path?
What does your datasource look like? Perhaps you can query the datasource based on what was selected in the search results to get the cell's index.
Sounds like a strange user interaction not knowing what you're doing though. Normally searching and then selecting will take you to that record's details or select it as an option or something.

In my app there is a table view with custom cell.in that cell there are (image view, views and labels).data loads succuessfully to the table.
Then what I wanted to display another view(detail view) when user tap on the cell.
I did it by (ctrl+drag) cell and connect it with the detail(second) view.
and selected the segue kind as Show.so then,when I click on a cell first time it correcly and and then I have to tap twice to load the detail view. I tried with changing kind to show Detail, present Modally, etc.but the no successful result. Then I tried with using navigation controller within these views.but didn't get any successful result.no idea what to do.I added some code and if you guys want more code I can provide.hope your help.thanx
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
FlightRoundtripDetails *setDetails = [RoundItineraryArray objectAtIndex:indexPath.row];
resultCell.firstdepatairiportCodeLabel.text = setDetails.FirstDepartureAirport;
resultCell.firstarriairportCodeLabel.text = setDetails.FirstArrivalAirport;
resultCell.firststopoverLabel.text = setDetails.Outbound;
}
data display correcly.only the issue is when tap a cell.hope your help.thanx.
I think u have set the tableview selection as Multiple. So goto Attributes Inspector and change the selection to Single.
At my experiment I need to have reference to first UITableViewCell in tableView. By some action I need to set image and some other cell properties and to keep this state of this only cell even if the tableView will be scrolled. All of this properties can be potentially nulled via scrolling (and they actually are) because of reusing. For set this properties every time cell appears on screen, inside of `-cellForRowAtIndexpath' I tried to catch first cell using:
UITableViewCell *firstCell = (UITableViewCell *)[atableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];
but looks like this way I can only catch every next first cell on next scrollable "screen".
So, how can I get ref to first UITableView cell?
If I understand you correctly, you are trying to do something special if the cell at (0, 0) is about to be displayed, right? If that's the case, you can easily implement UITableViewDelegate's tableView:willDisplayCell:forRowAtIndexPath: method as follows:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath) {
// Do something special
}
}
There is also a corresponding tableView:didEndDisplayingCell:forRowAtIndexPath: method if you need to undo things.
Hope it helps!
There is no "first" table view cell. The entire table view typically uses a single cell to improve performance.
You can change that, by implementing your own cell reuse system (search for reuse in the documentation). But generally the cell is the wrong place to store any data related to a specific index in the table view.
I want to implement the Tab View like Apple has in their Apple Maps when you select a location and tap on the more details to reviews additional information about that location.
What would be the best way to implement this or how do you think Apple has implemented it. I know each tab view has a Table View inside each. Also for the Photos tab how do you think they implemented the content inside that tab. Was it using UICollectionView or a table view with a custom cell that has 4 photos in each cell row?
It looks like they're using one UITableView and on UISegmentedControl. With this combination every time the user selects and index on the segmented control, it changes a condition in the table's datasource and reloads the data. Here's an example of what something like that could look like to conditionally change the number of rows in the table
- (IBAction)segmentValueDidChange:(UISegmentedControl *)sender
{
NSLog(#"%d",sender.selectedSegmentIndex);
[self.tableView reloadData];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (self.segment.selectedSegmentIndex == 0) {
return 5;
}
return 10;
}
It's My first time to post a question, thank you for you all in advanced.
Now, i want to implement a default style grouped UITableView contains multiple group of data. for each row, there will be a detail Disclosure button as accessoryType icon. when people click on the disclosure button, i want the Cell expand with detail info for the selected row.
i was trying to fulfill this task by add a customized cell to selected row, however, it was very complex. So currently, i am trying to finish this task by reload a specific row with Customized cell xib. i knew there is a delegate method for reloadRowsAtIndexPaths. but can i use this to reload a specific cell? Thanks
please suggest!
Great Thanks
Have you tried something like this:
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(indexPath.row == mySpecialSelectedCell)
{
//Load all your custom stuff here
}
else
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier];
}
if (cell == nil)
{
}
return cell;
}
You would have to get the cell's indexPath when you click the expand button.
Or you could look at this answer. And then, like the code above, just load that one cell that you have specified with that NIB and load the rest the way you would normally.
You can implement the tableview delegate methods to set the height for the cell which needs to expand. Add some condition check in heightForRow method and when user taps on button, change the condition to increase the height. When table is reloading it will call this method and will reload cell with bigger height.
I'd like to launch my "add item" form in response to touching an empty cell (the next blank cell), sort of like the stock "Reminders" app. didSelectRowAtIndexPath doesn't work for this and I don't have a clue what does.
Thanks
add a button to the tableFooterView
https://developer.apple.com/library/IOs/#documentation/UIKit/Reference/UITableView_Class/Reference/Reference.html
You could add a tap gesture recognizer to the table view, but be sure to test if the user tapped a table view cell or not.
If you wanna the last cell of your table view to be an add button so that you can add a cell directly without putting the table view in edit mode, then here is what you can do:
For the array you use to populate the table view, always make sure the last cell is a dummy object you use to add a row only.
in your -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath, make sure check whether indexPath.row is equal to [array count], if that's the same, then
insert whatever the object you create to your array at index = [array count]-1.
Call your [tableview reload] method. Then you will see the cell append to the table view.
Hope this helps.
