Question

我有这个问题，当我点击我的手机时，我的应用程序崩溃......

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
   DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
   detailViewController.title = [[colleges objectAtIndex:indexPath.row] objectForKey:@"name"];
   detailViewController.college = [colleges objectAtIndex:indexPath.row];
   [self.navigationController pushViewController:detailViewController animated:YES]; 
}

Answer 1

如果您使用的是storyboard，请使用nib名称删除init

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

[self performSegueWithIdentifier:@"YourSegueID" sender:self.view];

}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{

 if ([segue.identifier isEqualToString:@"YourSegueID"])
 {
    DetailViewController *detailViewController= segue.destinationViewController;
    detailViewController.title = [[colleges objectAtIndex:indexPath.row] objectForKey:@"name"];
    detailViewController.college = [colleges objectAtIndex:indexPath.row];

 }
}

如果你正在使用xib，那么交叉检查DetailViewController的xib。可能是你的xib名称有一些拼写错误。

Answer 2

//If you are using xib files then use this code

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
   DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
   detailViewController.title = [[colleges objectAtIndex:indexPath.row] objectForKey:@"name"];
   detailViewController.college = [colleges objectAtIndex:indexPath.row];
   [self.navigationController pushViewController:detailViewController animated:YES]; 
}

确保DetailViewController.xib在您的应用包中

//If you are using storyboards then use this code

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
   DetailViewController *detailViewController=[self.storyboard instantiateViewControllerWithIdentifier:@"detailViewController"];
   detailViewController.title = [[colleges objectAtIndex:indexPath.row] objectForKey:@"name"];
   detailViewController.college = [colleges objectAtIndex:indexPath.row];
   [self.navigationController pushViewController:detailViewController animated:YES]; 
}
