In my tableview I have number of rows that have disclosure detail button accessory type, and when pressing the row or the accessory, a new view is pushed to a navigation controller. I call the deselectRowAtIndexPath at the end of the didSelectRowAtIndexPath function.
If I press the accessory button, I go to a new view, but it remains highlighted when I come back to this view (pop). The row is deselected as expected but not this. Any thoughts on how to 'unhighlight' it?
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
...
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {
[tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionTop];
[self tableView:tableView didSelectRowAtIndexPath:indexPath];
}
For those who are still bothered by this and want a solution that appears to work right now, try this:
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {
[tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationNone];
[tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
}
You must reload the data FIRST and THEN select the row so that the highlight appears beneath your action sheet options.
Simply remove from your
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath;
method the statement
[tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionTop];
Since your table already allows selection, and you are correctly deselecting it in
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
you are done, because the row will be highlighted when selected pressing the disclosure button, and deselected when tableView:didSelectRowAtIndexPath: is executed.

I want to be able to select multiple rows like the default mail app shown below:
I have a button called edit that calls
[self.myTableView setEditing:YES animated:YES]
The edit button successfully shows the circles on the left of the cells like the mail app as shown above. However, when I actually select one of the rows, nothing happens. The red checkmark does not appear in the circle as I would expect. Why isn't the red checkmark appearing?

You have to explicitly set selection to be enabled during editing mode:
[self.tableView setAllowsSelectionDuringEditing:YES];
Or
[self.tableView setAllowsMultipleSelectionDuringEditing:YES];
According to the docs: these properties are set to NO by default.
If the value of this property is YES , users can select rows during
editing. The default value is NO. If you want to restrict selection of
cells regardless of mode, use allowsSelection.
Additionally, the following snippet of code may be causing problems with your selection because it immediately deselects the row as soon as it's been selected.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
I have created a custom cell that places a UITextField in each row of a UITableView. What I would like to do is enable the UITextField for a particular row (i.e. activate the cursor in that textfield), when the user presses on anywhere inside the cell.
I have the following method where I try to do this:
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[_cell.textField setUserInteractionEnabled:TRUE];
}
However, this is not working. Can anyone see what I'm doing wrong?
You're on the right track placing this inside didSelectRowAtIndexPath:. However, setting user interaction enabled on the textfield just means that the user would be allowed to interact with the object if they tried. You're looking for becomeFirstResponder.
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
[cell.textField becomeFirstResponder];
}
Try this code:
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[_cell.textField becomeFirstResponder];
}
What is this _cell iVar? Are you setting it somewhere?
I think what you are trying to accomplish is this:
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
[cell.textField becomeFirstResponder];
}
Notice that in this way you are getting the cell for the tapped indexPath.
And also, just for information, it's a pattern in objective-C to use booleans as YES or NO, instead of true or false.
What I was trying - I have a UITableView. On selecting any particular row it should show a selectionColor(Blue etc) and then it should disappear. Any property/code to do this? I am actually applying in in MyCalender view.
You can use [self.tableView deselectRowAtIndexPath:indexPath animated:YES];
in your - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
method.
You should refer the delegates and datasource in tableview for this
The datasource sets the inputs to table
The delegate gives you callbacks of actions on the tableview .
So write the delegate methods ,include it in classdef UITableViewDelegate,connect it in xib
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
This delegate method is invoked if you click on a particular row.The particular row is the row at the "indexpath"
finally include this line which deselect the code
[tableView deselectRowAtIndexPath:indexPath animated:YES];
add this to your - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
`
UIView *violetColor = [[[UIView alloc] init] autorelease];
//violetColor.backgroundColor = [UIColor colorWithRed:0.824 green:0.749 blue:0.553 alpha:0.70];
violetColor.backgroundColor = [UIColor colorWithRed:0.724 green:0.749 blue:0.953 alpha:0.70];
cell.selectedBackgroundView = violetColor;
`
and then add this to your didselect `
if (indexPath != nil) {
[mTableView deselectRowAtIndexPath:indexPath animated:YES];
}
`.i hope this will do the trick.
In delegate method didSelectRowAtndexPath use this code
[tableView deselectRowAtIndexPath:indexPath animated:YES];
If you are using UITableView and want to remove selection of the UITableViewCell. Then you have to use the below code to deselect tableview cell.
[tableView deselectRowAtIndexPath:[tableView indexPathForSelectedRow] animated:YES];
The code below seems to have no effect. I want it to be highlighed in the same way it highlights when you tap on a row
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
...
[cell.textLabel setHighlighted:YES];
return cell;
}
This line will handle repainting the cell, label and accessory for you:
[tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
As others have noted, you can programmatically select a cell using this method:
[tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
However, you should be careful not to call this method too soon.
The first time that the view controller containing said tableView is initialized, the earliest that you should call this method is within viewDidAppear:.
So, you should do something like this:
- (void)viewDidAppear:(BOOL)animated
{
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; // set to whatever you want to be selected first
[tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
}
If you try putting this call into viewDidLoad, viewWillAppear:, or any other early view lifecycle calls, it will likely not work or have odd results (such as scrolling to the correct position but not selecting the cell).
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:1 inSection: 0];
[tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
usually works
If you are using interface builder to build your interface, one thing to check is that you specified the view of the table view controller. If you don't actually specify the view, this selection message may go nowhere.
(you specify the view by selecting the table view controller in the interface builder inspector window and dragging the outlet for "view" to the table view you want to do the selection in).
- (BOOL)tableView:(UITableView *)tableView shouldHighlightRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
- (void)tableView:(UITableView *)tableView didHighlightRowAtIndexPath:(NSIndexPath *)indexPath {
// do something here
}
Try this :)
You can use
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
...
[cell.textLabel setHighlighted:YES];
return cell;
}
You have two choices. Either use the selection of the table view:
[tableView selectRowAtIndexPath: indexPath animated: YES scrollPosition: UITableViewScrollPositionNone];
Or change the background color of the table cell in the table view delegate:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
cell.backgroundColor = ...
}
I've put in this code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell * tableCell = [self.tableView cellForRowAtIndexPath:indexPath];
tableCell.accessoryType = UITableViewCellAccessoryCheckmark;
[tableView deselectRowAtIndexPath:(NSIndexPath *)indexPath animated:YES];
}
But for some reason, the checkmark doesn't appear. Could someone help?
Actaully, I figured it out, that's the right way to do it, its just it had a black bg so it was hard to see.
