I have an UITableView which loads data from three NSMutableArrays:
And when loading a little number of items it works ok, but when loading items (twitter followers) it crash saying me:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSMutableArray insertObject:atIndex:]: attempt to insert nil object at 2'
*** Call stack at first throw:
Then I went where it adds objects and removed the code, now the weird part is that the error is still there: I don't know where to find now:( thanks in advance! Code where I add data to the array ( on MGTwitterEngine method):
- (void)userInfoReceived:(NSArray *)userInfo forRequest:(NSString *)connectionIdentifier {
followers = [[NSMutableArray alloc] init];
followersname = [[NSMutableArray alloc] init];
followerspic = [[NSMutableArray alloc] init];
for(NSDictionary *d in userInfo) {
NSLog(@"See dictionary: %@", d);
NSString *user = [d objectForKey:@"screen_name"];
NSString *realname = [d objectForKey:@"name"];
NSString *pic = [d objectForKey:@"profile_image_url"];
[followers addObject:user];
[followersname addObject:user];
[followerspic addObject:user];
NSLog(@"%@", followers);
NSLog(@"%@", followersname);
NSLog(@"%@", followerspic);
}
[DSBezelActivityView removeViewAnimated:YES];
[self.tableView reloadData];
}
But removing it still gives error:(
And when the arrays are like this:

You haven't posted the code in question, but the exception simply says that in your call to insertObject:atIndex:
, you have passed nil
as object which is not allowed. If you want to add a value denoting no value , you have to insert [NSNull null]
instead.
