Xcode Search Bar - Can't search through NSObjects containing NSStrings - xcode

Question

So I'm adding a search bar to my custom tableview with custom cells, and it's giving an error.
-[Game rangeOfString:options:]: unrecognized selector sent to instance 0x170244e60
2016-10-15 15:41:49.557956 CustomCellApp[25930:7889617]
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Game rangeOfString:options:]: unrecognized selector sent to instance 0x170244e60
I'm populating my tableview by an array containing NSObjects which contain strings (gamesArray)and those strings I'm getting it from a JSON array (jsonArray), all from a php file connecting to a MYSQL server which have all the strings.
Here is the code for the search bar:
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
if (searchText.length == 0) {
isFiltered = NO;
} else {
isFiltered = YES;
filteredGamesArray = [[NSMutableArray alloc] init];
// ----- Problem Method ----- //
for (NSString *str in gamesArray) {
// ----- Crashes Here ----- //
NSRange stringRange = [str rangeOfString:searchText options:NSCaseInsensitiveSearch];
if (stringRange.location != NSNotFound) {
[filteredGamesArray addObject:str];
}
}
// ------------------------------------ //
}
[myTableView reloadData];
}
Here is the code for the tableView:
// Configuring the cell
Game * gameObject;
// Showing either Normal List or Filtered List
if (!isFiltered) {
gameObject = [gamesArray objectAtIndex:indexPath.row];
}
else {
gameObject = [filteredGamesArray objectAtIndex:indexPath.row];
}
Here is the code from server
It adds the strings from the server to a jsonarray which is then added to an NSObject to an array called gamesArray
NSString * gID = [[jsonArray objectAtIndex:i] objectForKey:#"id"];
NSString * gName = [[jsonArray objectAtIndex:i] objectForKey:#"gameName"];
NSString * gLabel1 = [[jsonArray objectAtIndex:i] objectForKey:#"gameLabel1"];
NSString * gLabel2 = [[jsonArray objectAtIndex:i] objectForKey:#"gameLabel2"];
NSString * gLabel3 = [[jsonArray objectAtIndex:i] objectForKey:#"gameLabel3"];
Any help would be greatly appreciated!
How can I fix this? Any ideas? Thank you
I think the problem is that when searching, the program is seeing that it has an array to search through, gamesArray, but when going inside it has 5 NSObjects, each containing strings, so it's not working because it doesn't know what to do.
As a solution, how can I make it that the search bar searches through the gamesArray, directly at 1 NSObject, the gameName , reading all the strings in that NSObject which is called gName
For example, this piece of code targets a specific NSObject inside the gamesArray
[[gamesArray objectAtIndex:indexPath.row] valueForKey:#"gameName"];

My first guess is: objects in games array are not strings, they are Game objects.
for (Game *game in gamesArray) {
NSString *str = game.fieldOfInterest;
// ----- Crashes Here ----- //
NSRange stringRange = [str rangeOfString:searchText options:NSCaseInsensitiveSearch];
if (stringRange.location != NSNotFound) {
[filteredGamesArray addObject:game];
}
}
This should address the issue of your crash. If the search behavior is not correct, please ask a new question related to your new issue. As a best guess, I would suggest you inspect your table delegate methods for how they behave when filtered is true.
