UITableView不响应透明区域的触摸

Question

I have a UITableView with a transparent backgroundColor , and the cells inside are initialized with the following code

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
  self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
  if (self) {
    self.label = [[UILabel alloc] initWithFrame:CGRectMake(0, 10, CGRectGetWidth(self.contentView.frame), 180)];
    self.label.autoresizingMask = UIViewAutoresizingFlexibleWidth;
    self.label.text = @"test";
    [self.contentView addSubview:self.label];
  }
  return self;
}

Each row has a height of 200, and the label doesn't fill up the entire cell. There will be transparent portions in between each cell. When I try to scroll the table by touching those transparent portions, the touches are completely ignored. I am aware that as of iOS5, touches on views will be ignored. What can I do to solve this?

Things I've tried that don't work:

Setting a transparent or hidden or alpha = 0 UIView to act as a fake background of the tableView

Same deal, touches are ignored.

Creating a subclassed UIView on top of the tableView, and the subclassed UIView uses tableView as the nextResponder

Apparently UITableView doesn't use touchesBegan/cancelled/ended/moved, so this doesn't work. I don't think it's wise to implement my methods to scroll the UITableView either.

Setting the backgroundColor of the tableView to [UIColor colorWithRed:0 green:0 blue:0 alpha:0.1]

I don't want to do this, it's still visible.

In short, what can I do to scroll the table even when I start the scrolling from the transparent section?

Answer 1

First you create a label with no text(or a view) such that it completely fills the cell. Then create a new label with your text and add this as a subview of the first view.
