I have a tableView with custom table cells which displays a list of sayings. While selecting a cell (say "saying1") from the tableView, the cell will get selected and will moves to next view controller for showing an explanation of selected saying. In that view controller two buttons "Previous" and "Next" are there for navigating to previous and next saying. So user may select next button for seeing next saying (say "saying2"). But the problem here is, In this stage when i navigate back to my tableview, the cell selected will be "saying1" not "saying2".
In order to solve this problem, i collected the currently selected sayings ("saying2's") index from array (ie,index will be 1) and passed it to the previous tableView through segue and converted that value into NSIndexpath. After this step i don't know what to do. Please help me in solving this.
You can specifically select a cell by calling following method present in UITableView class :
selectRowAtIndexPath:animated:scrollPosition:

I have a UITableView. It pulls information from the address book where needed. I also have the bottom cell programatically made to be a button that loads up the address book.
My problem is when I allow the user to delete a row by swiping right, it shows it for the last cell I have made as a button. Is there a way to not allow a delete function showing on just 1 cell?
Implement tableView:canEditRowAtIndexPath: in the table view's dataSource and return NO for the row you don't want to be deletable.
You have to implement [UITableViewDelegate tableView:editingStyleForRowAtIndexPath:] and return UITableViewCellEditingStyleDelete only for the cells that can be deleted. Return UITableViewCellEditingStyleNone for the cells that can't be deleted.
I am using a custom tableviewcell in one of my view's. I have decided to add a UISwitch to this cell to enable the user to delete multiple row's at once.
Normally when the user selects a row and taps my delete button I have a UIAlert pop up for confirmation and after that the alert clickedButtonAtIndex method handles the outcome. In that method I get the indexpath ( [self.myTableView indexPathForSelectedRow] ) and delete (or not) accordingly.
So basically as the title states instead of using the indexPath to fall into my delete statement, I need to check to see if self.myTableView.myCell.mySwitch.on is TRUE. Can anyone point me in the right direction for doing this? I will need to iterate through all rows in the tableview and for each row where the state is on it needs to be removed.
Thanks.
you should iterate through your cells using a nested loop ( or a single loop if you have only one section) and cellForRowAtIndexPath:.if you see a cell's switch.on = TRUE save it's indexPath in an array by calling indexPathForCell:. after you're done iterating through your cells, call deleteRowsAtIndexPaths:withRowAnimation: with the array previously created.
Is there a way to move the highlighted tableviewcell programatically. If I wanted to highlight cell number 3 and then highlight cell number 4 instead, based on something the user did in the detail view of my split view controller, can I do this?
Is there a way I can get the indexpath for the row two below one that I have?
Thanks!
You can do this via the UITableView selectRowAtIndexPath:animated:scrollPosition: method.
In terms of getting the "next" row from the indexPath, you can simply use the indexPath.row property (as supplied from your UITableViewDelegate's tableView:didDeselectRowAtIndexPath: method) as the basis for the selected row.
I'm trying to set up a UISearchBarDelegate
My first attempt was to clear the search results when searchBarShouldEndEditing: was called, but I discovered that this gets called when scrolling through the search results, which is not a time to be getting rid of the array of them.
My next attempt is searchBarCancelButtonClicked: - but this doesn't get called if the search bar is empty and they tap the space below (where a greyed out view of the table view is showing).
So how do you know when to switch from returning search results cells to returning regular table view cells?
Thanks for any help with this.
You can check which table view is requesting the cells. searchDisplayController.resultsTableView is what requests your search results cells. Just check for this in cellForRowAtIndexPath
I have a NSTableView that contains a NSButtonCell in one of the columns. I can set up the action that is called when the button is clicked in Interface Builder fine, but I can't find anyway to determine which row in the table that the button exists in. Is there any way to do this?
Thanks. :)
The cell for a particular column is reused throughout the whole table so there isn't one cell per row by default. You can get the the row that was clicked on though in your action method by sending the clickedRow message to the cell's table view.
NSInteger clickedRowIndex = [tableView clickedRow];
