DisclosureIndicator不检测触摸 [英] DisclosureIndicator does not detect touches
问题描述
我使用 UITableViewCellAccessoryDisclosureIndicator 作为 accessoryType 我的 UITableViewCell 。根据Apple的文档，数据源方法
I am using UITableViewCellAccessoryDisclosureIndicator as accessoryType of my UITableViewCell. According to Apple's documentation, the data source method
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
应自动调用。
如果启用单元格并且附件类型为UITableViewCellAccessoryDetailDisclosureButton，则附件视图会跟踪触摸，并在点击时向数据源对象发送tableView：accessoryButtonTappedForRowWithIndexPath：message。
If the cell is enabled and the accessory type is UITableViewCellAccessoryDetailDisclosureButton, the accessory view tracks touches and, when tapped, sends the data-source object a tableView:accessoryButtonTappedForRowWithIndexPath: message.
这里是我的代码：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
[cell.textLabel setText:[datasource objectAtIndex:indexPath.row]];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
数据源方法只是一个 NSLog 但没有打印...
The data source method is just a NSLog but nothing is printed...
我错过了什么？ （当然，数据源和代理设置正确）
Am I missing something? (of course, data source and delegate are set properly)
推荐答案
答案在你的问题。您说
我使用UITableViewCellAccessoryDisclosureIndicator作为
accessoryType ...
I am using UITableViewCellAccessoryDisclosureIndicator as accessoryType ...
您在部分
如果启用单元格， UITableViewCellAccessoryDetailDisclosureButton ...
If the cell is enabled and the accessory type is UITableViewCellAccessoryDetailDisclosureButton ...
只有当您使用 UITableViewCellAccessoryDetailDisclosureButton 。区别当然是，这是一个按钮， UITableViewCellAccesssoryDisclosureIndicator 不是。当你使用后者，点击它就像点击单元格本身。您可以创建一个自定义单元格并实现 hitTest：来确定轻敲是否接近公开指示符，但似乎比必要的更多的工作（除非您<真的不想使用详细信息按钮）。
Only when you use UITableViewCellAccessoryDetailDisclosureButton is the delegate method called. The difference, of course, is that this is a button, where UITableViewCellAccesssoryDisclosureIndicator is not. When you use the latter, tapping it is like tapping the cell itself. You could create a custom cell and implement hitTest: to determine if the tap was "near" the disclosure indicator, but that seems like more work than necessary (unless you really don't want to use a detail disclosure button).
