Swipe to delete option in UITableView issues

问题:

I want to use "swipe to delete" option in my project.

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath 
{

    if (editingStyle == UITableViewCellEditingStyleDelete)
    {
        NSDictionary *userData = [_contactsArray objectAtIndex:indexPath.row];
        NSLog(@"delete row %@",userData);
    }
}

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{

    return YES;
}

I am using this code but it gives following output which I don't want.

I don't want that left side minus sign on cell. I just want swipe and show delete button. The same code I have used in my previous project and it works fine (i.e only swipe to show delete button, no minus sign on left side)

Please help me to solve this.

回答1:

You are overriding the correct delegate methods for 'swipe to delete' functionality. Regarding the minus signs:

Hide minus sign like this:

self.yourTableView.editing = NO;
//or simply remove this line of code altogether because this property is NO by default

Show minus sign like this:

self.yourTableView.editing = YES;

First create your table view and set delegate and datasource method to that.

 self.contacts=[[UITable alloc]init];
    self.contacts.dataSource=self;
    self.contacts.delegate=self;
    self.contacts.userInteractionEnabled=YES;
    //self.contacts.editing = YES;
    [self.view addSubview:self.contacts];

And then Override the Delegate and data source methods, for delete override the following methods.

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
        // Return YES if you 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) {
            //add code here for when you hit delete
        }    
    }

For minus sign on left side use self.contacts.editing = YES; In my case I don't want this minus sign so simply don't use that property or set self.contacts.editing = NO;

Thank you hw731 for reminding me this property, I have wasted my half day on this.

Try this:

 - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
        // Return YES if you 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) {
            //add code here for when you hit delete
        }    
    }

Sounds like you are turning the tableView.editing flag on so the rows show up with the minus sign. try searching for self.tableView.editing = YES; and make it NO or simply comment that line out.
