我已经UITableViewController
didSelectRowAtIndexPath
通过以下方式覆盖了我的方法:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
PhotoListViewController *photosViewController = [[PhotoListViewController alloc] initWithStyle:UITableViewStylePlain];
NSLog(@"Let's see what we got %d", [[fetchedResultsController fetchedObjects] count]);
Person *person = [fetchedResultsController objectAtIndexPath:indexPath];
photosViewController.person = person;
photosViewController.title = [person.name stringByAppendingString:@"'s Photos"];
[self.navigationController pushViewController:photosViewController animated:YES];
[photosViewController release];
}
每当我尝试访问时,fetchedResultsController
我都会崩溃,我在这里设置它:
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"person = %@", person];
fetchedResultsController = [[FlickrFetcher sharedInstance] fetchedResultsControllerForEntity:@"Photo" withPredicate:predicate];
}
return self;
}
而且我只在我的dealloc
方法中发布它
