How I can use the Detail Disclosure Button whith Storyboard?
提问by Bernhard B
I try to use the Detail Disclosure Button with the Storyboard, but when I build a segue from Disclosure Button to a new View it works only, when I press the table cell and not, when I press the Detail Disclosure Button.
我尝试将 Detail Disclosure Button 与 Storyboard 一起使用，但是当我构建从 Disclosure Button 到新视图的 segue 时，它仅在我按下表格单元格时起作用，而不是在按下 Detail Disclosure 按钮时起作用。
What must I do?
我必须做什么？
Thanks,

I may be wrong but I have found that it needs to be implemented through UITableDelegate code:
我可能错了，但我发现它需要通过 UITableDelegate 代码来实现：
#pragma mark - Table view delegate methods
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
// do a segue based on the indexPath or do any setup later in prepareForSegue
[self performSegueWithIdentifier:@"segueName" sender:self];
}
And then in your prepareForSegue
然后在你的 prepareForSegue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:@"segueName"]){
NSIndexPath * indexPath = self.sequenceTableView.indexPathForSelectedRow;
// do some prep based on indexPath, if needed
}
}

skinnyTOD's answer is fine. But I don't know why self.sequenceTableView.indexPathForSelectedRow; returns nil(0x0000000), I have to use a property to save the selectedRow in accessoryButtonTappedForRowWithIndexPath:
skinnyTOD 的回答很好。但我不知道为什么 self.sequenceTableView.indexPathForSelectedRow; 返回 nil(0x0000000)，我必须使用一个属性将 selectedRow 保存在 AccessoriesButtonTappedForRowWithIndexPath 中：
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {
// do a segue based on the indexPath or do any setup later in prepareForSegue
self.selectedRow = indexPath.row;
[self performSegueWithIdentifier:@"segueName" sender:self];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"segueName"]) {
// use self.selectedRow here
}
}
