Swipeable table view cell with default action - ios

iOS8 now provides a way to create swipeable table view cell with actions. In Apple's own Mail app, you can also commit to a default action if you drag the cell all the way (Mail app shows More | Flag | Trash and defaults to Trash if you drag all the way and release). Is there a way to do this in iOS 8?

If your are referring to the swipe to delete on TableViews you can use this code:
//Enable multiple selections during editing
self.tableView.allowsMultipleSelectionDuringEditing = NO;
//Enable editing row
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
// Return YES if you want the specified item to be editable.
return YES;
}
//Do something on delete
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
//add code here for when you hit delete
}
}

What you're looking for is not in a public API yet. Luckily, someone has already done the legwork :)

Swipe to delete and XLPagerTabStrip

I am using XLPagerTabStrip to swipe between pages. One of those pages has a tableview. I am trying to implement swipe to delete on this tableview, but the DELET button only shows from time to time when swiping.
This is the code I have:
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
if ([storiesArray count] >= 1) {
// code to delete row
}
}
}
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"I am allowing a swipe");
// Return YES if you want the specified item to be editable.
return YES;
}
I can see the NSLog I am allowing to swipe so I know the swipe has been detected, but I can only see the DELETE button occasionally. I can't find the reason why it does not show the delete button. I have searched every post on this, and have asked xmartlabs if implementing their code would affect swipe to delete, but it doesn't make sense that it does work occasionally.
Would anyone have any idea what else I can do to understand why the delete button doesn't show ALWAYS?
Thanks.
You can disable scrolling on XLPagerTabStrip's containerView, so the scrolls will be handled by inner views.

Detect cell click in cell edit showing reordering control + disclosure control as Safari bookmarks editing

I am trying to reproduce behaviour of editing bookmarks in iOS Safari like shown here:
I managed to reproduce the look but I am struggling to detect cell click in editing mode when showing both reordering control and disclosure editing accessory type setting:
cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator;
Basically only the reordering and delete controls seem active, but the delegate method
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
does not get called ever, how is this achieved then?
Please note I am using UITableViewController, I have implemented also:
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
// avoid moving "add new" row
if (indexPath.row > 0) {
return YES;
}
return NO;
}
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
return indexPath.row > 0 ? UITableViewCellEditingStyleDelete : UITableViewCellEditingStyleInsert;
}
You need to set the allowsSelectionDuringEditing to YES.
From Documentation:
A Boolean value that determines whether users can select cells while
the table view is in editing mode.
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.

iOS UITableView - Show delete button upon both swipe left and click cell

I have a UITableView and also implemented the logic to swipe to show the delete button, as such:
-(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
-(void)tableView:(UITableView *)tableViefw commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete {
//logic to delete...
}
}
However, I need a way for the delete button to also show up when the user clicks on a table cell. Is that possible?
I've seen other answers that suggest using [tableView setEditing: true], but that also shows the red icon on the left and I don't want that.
Thanks.
If you subclass UITabeViewCell, then you can use the didSelectRowAtIndexPath: method to get the clicked cell, you can then show a delete button (whatever design you want), and when that is clicked the cell gets deleted front the datasource and the tableView gets updated, whether there is a framework way of doing it, I do not know.
But good luck anyway :)
Try this method..
When deleting a row you must remove that data form your array. After that you need to reload tableview again to show the updated tableview
- (void)viewDidLoad
{
Your_tableview.editing=YES;
[super viewDidLoad];
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if(editingStyle == UITableViewCellEditingStyleDelete)
{
NSLog(#"Delete Success");
[Your_Array removeObjectAtIndex:indexPath.row];
[self.Your_tableView reloadData]
}
else
{
NSLog(#"Delete Canceled");
}
}

how to enable editing mode on UITableViewCell programmatically?

I am developing an app which has a PageViewController and two view controllers as children of it. One of the Child View controllers has a UITableView.
The problem occurs when I swipe the child view controller. I want to have two functionalities like there should be a swipe for delete on tableView.
When I swipe the child view controller it sends swipe to pageViewController. So it does not show the delete button when we swipe a table view cell.
I want to have two functionalities on swipe event so that there would be both:
Swapping of view
Show red delete button on row
Try this,
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
//delete your data here
}
}
You should return YES to this method of the UITableViewDataSource protocol to tell the tableView your cell can respond to the swipe to let appear the delete button:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
// Return NO if you do not want the specified item to be editable.
return YES;
}
and then delete your data in this method, called when the user taps the delete button:
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Remove here your data
...
// This line manages to delete the cell in a nice way
[tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
}

Swipe to Delete for a table already in edit mode

I have a tableview that loads with isEditing = YES. This is a bit of a hack (but a reasonable one I think) because I want one of my cells to always display the 'add' icon. I don't want the other cells to include the 'delete' icon so I am returning UITableViewCellEditingStyleNone for these.
However, I would still like to provide swipe to delete functionality on those cells. Since the tableview is already in edit mode, is this going to be possible?
If not, I will probably achieve the 'add' icon using the cells imageView, but this seems hacky too.
Edit: Similar question found here:
swipe to delete when already in edit mode
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{
return YES;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
if (editingStyle == UITableViewCellEditingStyleDelete) {
[myArray removeObjectFromindex];
}
[mytableview reloadData];
}
