Im trying to make a UITableView with a View with Details but I get two errors. After the following code I got two times the same errors: 'Internal compiler error: Bus error' and I have no idea why? Can someone help me? You can find a image of the code under here.

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

NSInteger row = [indexPath row];
if (self.verwaltungDetailViewController == nil){
    verwaltungDetailViewController *aVerwaltungDetail = [[verwaltungDetailViewController alloc] initWithNibName:@"VerwaltungDetailView" bundle:nil];
    self.verwaltungDetailViewController = aVerwaltungDetail;
    [aVerwaltungDetail release];

}
verwaltungDetailViewController.title =  [NSString stringWithFormat:@"%@", [verwaltungsArray objectAtIndex:row]];



NatersAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
[delegate.VerwaltungNavController pushViewController:verwaltungDetailViewController animated:YES];

}

为您的帮助！

推荐答案

看起来像我有一个类 code> VerwaltungDetailViewController （注意大写的V），你将它与一个实例变量& verwaltungDetailViewController （请注意小写的v）。在 if 块的第一行，当您尝试创建前者的实例时，您正在尝试创建后者的实例。您的代码应该看起来像这样：

It looks to me like you've got a class somewhere called VerwaltungDetailViewController (note the uppercase 'V') and you are mixing it up with an instance variable & property called verwaltungDetailViewController (note the lowercase 'v'). In the first line of the if block, you are attempting to create an instance of the latter, when you should be attempting to create an instance of the former. Your code should look something like this:

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

NSInteger row = [indexPath row];
if (self.verwaltungDetailViewController == nil){
    VerwaltungDetailViewController *aVerwaltungDetail = [[verwaltungDetailViewController alloc] initWithNibName:@"VerwaltungDetailView" bundle:nil];
    self.verwaltungDetailViewController = aVerwaltungDetail;
    [aVerwaltungDetail release];

}
verwaltungDetailViewController.title =  [NSString stringWithFormat:@"%@", [verwaltungsArray objectAtIndex:row]];



NatersAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
[delegate.verwaltungNavController pushViewController:verwaltungDetailViewController animated:YES];

编辑：您也在最后一行代码中犯了错误，除非相反。

You also make the mistake in the last line of code, except in reverse.
