UITableViewCell.showingDeleteConfirmation gives NO when the delete-confirmation button is shown - ios

Question

I swipe on a table view cell to reveal the delete-confirmation button. But once I lift my finger, showingDeleteConfirmation gives NO even if the button is still there. (It does give YES when the button is showing up, I mean, before I lift my finger.) Am I missing something, or it's a real bug in iOS?
Following is my test code. (Copy&paste it into ViewController.m of a single-view project and run it in the simulator, and shift+command+M to trigger the NSLog.)
#import "ViewController.h"
#interface ViewController () <UITableViewDataSource, UITableViewDelegate>
#end
#implementation ViewController {
UITableViewCell *_myCell;
}
- (void)viewDidLoad
{
[super viewDidLoad];
UITableView *myTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 100, 320, 200)];
myTableView.dataSource = self;
myTableView.delegate = self;
[self.view addSubview:myTableView];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
_myCell = [[UITableViewCell alloc] init];
_myCell.contentView.backgroundColor = [UIColor greenColor];
return _myCell;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
NSLog(#"_myCell.showingDeleteConfirmation = %#", _myCell.showingDeleteConfirmation ? #"YES" : #"NO");
}
#end

Answer 1

According to documentation:
Returns whether the cell is currently showing the delete-confirmation button. (read-only)
...
When users tap the deletion control (the red circle to the left of the cell), the cell displays a "Delete" button on the right side of the cell
So first you need to make grid editable
[myTableView setEditing:YES];
then user taps circle to delete (they not able to swipe left in this mode), and voilà:
_myCell.showingDeleteConfirmation = YES
While you can expect to use it as you described in your question, they don't promise it.
