Can get members, but not count of NSMutableArray
- by Curyous
I'm filling an NSMutableArray from a CoreData call. I can get the first object, but when I try to get the count, the app crashes with Program received signal: “EXC_BAD_ACCESS”. How can I get the count?
Here's the relevant code - I've put a comment on the line where it crashes.
- (void)viewDidLoad {
[super viewDidLoad];
managedObjectContext = [[MySingleton sharedInstance] managedObjectContext];
if (managedObjectContext != nil) {
charactersRequest = [[NSFetchRequest alloc] init];
charactersEntity = [NSEntityDescription entityForName:@"Character" inManagedObjectContext:managedObjectContext];
[charactersEntity retain];
[charactersRequest setEntity:charactersEntity];
[charactersRequest retain];
NSError *error;
characters = [[managedObjectContext executeFetchRequest:charactersRequest error:&error] mutableCopy];
if (characters == nil) {
NSLog(@"Did not get results for characters: %@", error.localizedDescription);
}
else {
[characters retain];
NSLog(@"Found some character(s).");
Character* character = (Character *)[characters objectAtIndex:0];
NSLog(@"Name of first one: %@", character.name);
NSLog(@"Found %@ character(s).", characters.count); // Crashes on this line with - Program received signal: “EXC_BAD_ACCESS”.
}
}
}
And previous declarations from the header file:
@interface CrowdViewController : UITableViewController {
NSManagedObjectContext *managedObjectContext;
NSFetchRequest *charactersRequest;
NSEntityDescription *charactersEntity;
NSMutableArray *characters;
}
I'm a bit perplexed and would really appreciate finding out what is going on.
