在iOS 8.1中，当我在UITableView处于编辑模式时单击行的删除按钮时，该行及其上方的行显示不正确

Question

I have a UITableView showing cells under different sections. The cells within each section can be deleted. Ie, when the UITableView is in edit mode, the cells' styles are set to UITableViewCellEditingStyleDelete. When the user clicks the delete button within a cell with this style, the Delete confirmation button shows to the right as expected. Since updating to iOS version 8.1, the row's contents and the contents of the section header cells above it are skewed to the left.

In Delete Mode, before clicking on delete button on the left hand side

After clicking on delete button on the left hand side

This was working fine up until I updated to iOS version 8.1. Has anyone else run into this?

Edit: Relevant snippets of code

{
   return [[_store getGroceryAisles] itemCount];

Answer 1

in the method:

-(UITableViewCell*)tableView:(UITableView*)tableView viewForHeaderInSection:(NSInteger)section
{
    ...
    return cell;
}

Instead of return the cell object, try to return the contentView.

-(UITableViewCell*)tableView:(UITableView*)tableView viewForHeaderInSection:(NSInteger)section
{
    ...
    return cell.contentView;
}

I have solved my problem in that way. I am using Swift, but it seems the same way in Objective-C.

Answer 2

My problem was that I as returning a UITableViewCell from "viewForHeaderInSection". The behavior was corrected by returning the contentView of the cell instead.

Interesting that the original code worked fine in iOS 7. I don't know if it was working by design or by accident. Ie, since UITableCellView inherits from UIView, I am not certain that returning a UITableViewCell is really incorrect. As an fyi (in case it helps someone else looking to implement custom headers and footers), I got the idea of returning the contentView property from How to Implement Custom Table View Section Headers and Footers with Storyboard .

Answer 3

Try this

First Edit button add to NavigationBar in Top of ViewControl

 -(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if(editingStyle == UITableViewCellEditingStyleDelete)
{
    [imagearray removeObjectAtIndex:indexPath.row];
    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];


}
    else if(editingStyle == UITableViewCellEditingStyleInsert)
    {

    }
}

I hope it's Work for you
