I would like to do some stuff when a user swipes to the right of a UITableViewCell, so I use
- (void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath
However I tried to slide to the right and this didn't get invoked, why is this? All of my UITableView delegates are invoked.
I also have this in my code:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
}
All I want to do is to add a subview when a swipe happens
Do you have a tableView:commitEditingStyle:forRowAtIndexPath: method?
To quote Apple:
Note: A swipe motion across a cell does not cause the display of a Delete button
unless the table view's data source implements the
tableView:commitEditingStyle:forRowAtIndexPath: method.
And, deleting that method in my project also causes the willBeginEditing not to be called.
// You missed this?
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)theTableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
return UITableViewCellEditingStyleDelete;
}
- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath {
return #"Remove";
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:YES];
}
}
Hope that helps.
Try adding this method to your tableView delegate methods:
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Delete the row from the data source.
[self.listTableView beginUpdates];
...
I assume because your other delegate methods are being called that you included in your .h file #interface line? If using IB did you right click on the tableview and wire up delegate and dataSource?
Set the property of table view
tableView.editing = YES;

All,
I am using UITableview and trying to implement an edit/delete function.
When I call this line .
[tblStoreAvail setEditing:TRUE animated:TRUE];
The cell's content goes out of screen.
These functions are never called.
- (void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath
- (void)tableView:(UITableView *)tableView didEndEditingRowAtIndexPath:(NSIndexPath *)indexPath
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
If you are using custuomTableViewCell implement the following method with your required frame for the label:
- (void)willTransitionToState:(UITableViewCellStateMask)state
{
[super willTransitionToState:state];
if(state == UITableViewCellStateDefaultMask)
{
[self.lblLocation setFrame:CGRectMake(13,22,302,21)];
}
else if(state == UITableViewCellStateShowingDeleteConfirmationMask)
{
[self.lblLocation setFrame:CGRectMake(13,22,245,21)];
}
else if(state == UITableViewCellStateShowingEditControlMask)
{
[self.lblLocation setFrame:CGRectMake(13,22,245,21)];
}
else
{
[self.lblLocation setFrame:CGRectMake(13,22,210,21)];
}
}
if you are using default TableViewCell then make sure to set delegate for tableView and do like below :
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
yourCustomCell *cell = (yourCustomCell *)[tableView cellForRowAtIndexPath:indexPath];
[cell.lblLocation setFrame:CGRectMake(13,22,302,21)];
return YES;
}
You've got two problems going on, Taimur.
1) you need to set the "delegate" of your table to whatever object (presumably your view controller) that holds those delegate methods. You can do this programmatically or via a connection in the XIB / storyboard.
2) if you're using a custom cell, you need to adjust the font sizes down to hold all the data you want to display.
If you're not using custom UITableViewCell objects to display the data in your table, then start to use them so you can get the formatting you really want to see.
I have a UITableView put in edited mode.
self.tableView.editing = YES;
In this table view, I have some lines displayed in a custom cell, and I'd like to add one at the end that would allow the user to add an item (using another view).
So I wrote some lines :
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return "number of lines" + 1;
}
- (BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
if(indexPath.row+1 != [tableView numberOfRowsInSection:0]) {
return UITableViewCellEditingStyleDelete;
}
else {
return UITableViewCellEditingStyleInsert;
}
}
- (void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row + 1 == [tableView numberOfRowsInSection:0]) {
cell.textLabel.text = #"Add a line...";
}
else {
do the stuff in the custom cell
}
}
Doing this way, the UITableView allows to rearrange any line. I can move the first line after the "add line", and move the "add line" in first position.
How may I remove the arrange button on the "add line" cell and prevent other lines to go under this one ?
Or is there a better way to code this ?
Implement
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
return ([indexPath row] != INDEX_OF_SPECIAL_ROW)
}
and
- (NSIndexPath *)tableView:(UITableView *)tableView
targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath
toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath
{
if ([proposedDestinationIndexPath row] < NUMBER_OF_ROWS)
{
return proposedDestinationIndexPath;
}
NSIndexPath *otherPath = [NSIndexPath indexPathForRow:NUMBER_OF_ROWS-1 inSection:0];
return otherPath;
}
The much easier way would be to set a tableFooterView. You can place any UIView in there, so not only are you allowed to add a UITableViewCell but also a completely custom subclass. Doing it this way you will avoid all the unnecessary checks.
return UITableViewCellEditingStyleNone
For that row in - (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
And check out – tableView:moveRowAtIndexPath:toIndexPath:
Here is my previous thread: Need Help Adding User's Text To NSArray.
I want to enable the edit, delete, and move buttons for my array in the UIViewTable.
The ViewController has the following methods commented out by default but I'm not sure which ones and how to use them.
// Override to support conditional editing of the table view.
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
// Return NO if you do not want the specified item to be editable.
return YES;
}
// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Delete the row from the data source
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
else if (editingStyle == UITableViewCellEditingStyleInsert) {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
}
}
// Override to support rearranging the table view.
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
}
// Override to support conditional rearranging of the table view.
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
// Return NO if you do not want the item to be re-orderable.
return YES;
}

hey look out that link
i think it will help
I am basically getting no response after i had gone into edit mode using :
[self.tableView setEditing:NO animated:YES];
I set commitEdittingstyle:
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath;
To see that I would get a response, but i am not getting any sort of response after i had touch on the delete button.
any help?
Check This
[self.tableView setEditing:YES animated:YES];
(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete){
// Delete your data
// Update your table view
}
}
I am looking to allow reordering of UITableViewCells and deleting via swipe to delete, but not via the red delete circle.
- (void)loadView
{
[super loadView];
[table setEditing:YES animated:NO];
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Perform delete here
}
}
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
// Perform move here
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
return UITableViewCellEditingStyleDelete;
}
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
Additionally, I've tried disabling the edit mode and calling -[UITableViewCell setShowsReorderControl:YES] with no luck.
(source: booleanmagic.com)
I think you'll have to do some custom touch event interception.
In english:
if finger moved, x distance, horizontally across cell, in that cell only, then show delete control.
Not sure how to turn off the circles to the left, but I do think it's a property like "shows reorder control"
