我有一个 UISearchDisplaycontroller，我必须将信息推送到文本字段，并需要将其链接到导航视图控制器。
这是我的代码 -
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"showRecipeDetail"]) {
NSIndexPath *indexPath = nil;
Recipe *recipe = nil;
if (self.searchDisplayController.active) {
indexPath = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
recipe = [searchResults objectAtIndex:indexPath.row];
} else {
indexPath = [self.tableView indexPathForSelectedRow];
recipe = [recipes objectAtIndex:indexPath.row];
}
RecipeDetailViewController *destViewController = segue.destinationViewController;
destViewController.recipe = recipe;
}
}
您的 UINavigationController 层次结构错误或放置错误。
