POuitableview reloadRowsAtIndexPaths not working
text
Body
copied!<p>I have a <code>tableviewcell</code> in the <code>RegisterViewController</code>, when i click on it, it push to the <code>SelectCityViewController</code> where i can pick a city from a <code>uipickerview</code>. and I have defined a delegate in the <code>SelectCityViewController</code>. But when i implement the delegate method, i got the city back from the <code>pickerview</code> and the selected <code>indexpath</code> from <code>didSelectRowAtIndexPath</code> in <code>RegisterViewController</code>. When i check the log, i get the city, and the selected <code>indexpath</code>. but when i call <code>reloadRowsAtIndexPaths</code>, the cell still got the old titlelabel text. the code:</p> <pre><code>SelectCityViewController.h @protocol SelectCityDelegate <NSObject> - (void)didGetCity:(City *)city; @end SelectCityViewController.m - (void)finished:(UIBarButtonItem *)buttonItem { if ([self.delegate respondsToSelector:@selector(didGetCity:)]) { [self.delegate didGetCity:self.city]; } NSLog(@"%@", self.city.city); [self.navigationController popViewControllerAnimated:YES]; } RegisterViewController.m - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.section == 2) { self.selectedIndexPath = indexPath; UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil]; SelectCityViewController *signUp = [storyBoard instantiateViewControllerWithIdentifier:@"SignVC"]; signUp.delegate = self; [self.navigationController pushViewController:signUp animated:YES]; } } - (void)didGetCity:(City *)city { NSLog(@"%@", city.city); NSLog(@"%@", selectedIndexPath); UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:selectedIndexPath]; cell.textLabel.text = city.city; [self.tableView reloadRowsAtIndexPaths:@[selectedIndexPath] withRowAnimation:UITableViewRowAnimationFade]; } </code></pre>
