自定义 UITableViewRowAction 按钮

我想为 uitableviewrowaction 按钮设置顶部和底部约束

这是我的代码

- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath {
        UITableViewRowAction *deleteAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@"Delete"  handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){

       }];
        deleteAction.backgroundColor = [UIColor redColor];

       return @[deleteAction];
  }

像这样我添加了删除按钮。在tableviewCell我已经添加了一个UIView它有顶部和底部约束。我希望删除按钮与我的视图相匹配UITableviewCell.

你可以设置删除按钮自定义 uitableviewcell 类中的框架

像这样

 -(void)didTransitionToState:(UITableViewCellStateMask)state
{
    [super didTransitionToState:state];
    if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask)
    {

        UIView *deleteButton = [self deleteButtonSubview:self];
        if (deleteButton)
        {
            CGRect frame = deleteButton.frame;
            frame.origin.y = 4;
            frame.size.height = frame.size.height-8;
            /*
            if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
            {

                frame.size.height = 62; //vikram singh 2/1/2015
                frame.size.width = 80;

            }
            else
            {
                frame.size.height = 52; //vikram singh 2/1/2015
                frame.size.width = 80;

            }
             */
            deleteButton.frame = frame;

        }
    }
}

- (UIView *)deleteButtonSubview:(UIView *)view
{
    if ([NSStringFromClass([view class]) rangeOfString:@"Delete"].location != NSNotFound) {
        return view;
    }
    for (UIView *subview in view.subviews) {
        UIView *deleteButton = [self deleteButtonSubview:subview];
        [deleteButton setBackgroundColor:[UIColor whiteColor]];
        if (deleteButton) {

            return deleteButton;
        }
    }
    return nil;
}

use didTransitionToState方法 ：）
