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才有效,而不是在我按下 Detail Disclosure Button 时。
我必须做什么?
谢谢,

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];
}
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 的回答很好。但我不知道为什么 self.sequenceTableView.indexPathForSelectedRow; 返回 nil(0x0000000),我必须使用属性将 selectedRow 保存在 accessoryButtonTappedForRowWithIndexPath 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
}
}
