Exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 19 beyond bounds [0 .. 18]'
I haver already looked for the other similar post, but none has solved my problem. I get this error:
*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 19 beyond bounds [0 .. 18]'
I'm using a Searchbar and Display Controller getting data from a PARSE.COM database.
This is my code:
#import "busquedaViewController.h"
@interface busquedaViewController ()
@end
@implementation busquedaViewController
@synthesize totaldetalles;
@synthesize resultados;
@synthesize busquedaTableView;
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
// [self.activityIndicatorView startAnimating];
}
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
// [self.resultados removeAllObjects];
PFQuery *busqueda = [PFQuery queryWithClassName:@"icd_detalle"];
[busqueda whereKey:@"DESC_ES" containsString:[searchText uppercaseString]];
[busqueda findObjectsInBackgroundWithBlock:^(NSArray *results, NSError *error) {
if(!error){
resultados = [[NSMutableArray alloc] initWithArray:results];
NSLog(@"ACA LA DATA YA FILTRADA ...%@ ... TADA", resultados);
} else {
NSLog(@"error en la busqueda");
}
}];
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex:[self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}

// Dispose of any resources that can be recreated.

}
}

return 80;
}

} else if (tableView == self.searchDisplayController.searchResultsTableView) {

cell.busquedaCode.text = [tempDict objectForKey:@"COD_4"];
// [self.activityIndicatorView stopAnimating];
}
return cell;
}

Answer
This exception is because you update the array in findObjectsInBackgroundWithBlock but tableView is updating on the main thread callbackLoadObjectsFromParse.
tableView has 19 rows but array only has 18.
