iphone - 在 UITableView 单元格中编辑时自定义删除按钮

Question

我已经浏览过this question显示以下代码:

-(NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath{
    return @"Sagar";
}

如果我想要自定义图像而不是默认的红色按钮怎么办？

Answer 1

在自定义单元格中实现此方法

- (void)willTransitionToState:(UITableViewCellStateMask)state{
    [super willTransitionToState:state];
    if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask) {
        for (UIView *subview in self.subviews) {
            if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"]) {
                UIImageView *deleteBtn = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 64, 33)];
                [deleteBtn setImage:[UIImage imageNamed:@"delete.png"]];
                [[subview.subviews objectAtIndex:0] addSubview:deleteBtn];
                [deleteBtn release];
            }
        }
    }
}
