I have a tableview with a search display controller. It has been working fine in the past, but recently has started crashing for certain search results. Here my code searches a Golfer based on their Name, Age and Handicap. The data is correctly loaded into the table, I can access and drill down to receive further information. However when I type in a search query for either Name or Age, the app crashes, while the Golfers Handicap is returned fine.
Note: dataSouceArray is the data source for the tableview, dataSourceArrayCopy is the mutable copy of the data used to add and remove objects in the search filter.
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
/*
Update the filtered array based on the search text and scope.
*/
[self.dataSourceArrayCopy removeAllObjects]; // First clear the filtered array.
/*
Search the main list for products whose type matches the scope (if selected) and whose name matches searchText; add items that match to the filtered array.
*/
for (Golfer *golfer in dataSourceArray)
{
if ([scope isEqualToString:@"Name"] || [golfer.golferName isEqualToString:scope])
{
NSComparisonResult result = [golfer.golferName compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])];
if (result == NSOrderedSame)
{
[self.customerListCopy addObject:golfer];
}
}
if ([scope isEqualToString:@"Age"] || [golfer.golferAge isEqualToString:scope])
{
NSComparisonResult result = [golfer.golferAge compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])];
if (result == NSOrderedSame)
{
[self.dataSourceArrayCopy addObject:golfer];
}
}
if ([scope isEqualToString:@"Handicap"] || [golfer.golferHandicap isEqualToString:scope])
{
NSComparisonResult result = [golfer.golferHandicap compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])];
if (result == NSOrderedSame)
{
[self.dataSourceArrayCopy addObject:golfer];
}
}
}
}
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString scope:
[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];
// Return YES to cause the search result table view to be reloaded.
return YES;
}
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption
{
[self filterContentForSearchText:[self.searchDisplayController.searchBar text] scope:
[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:searchOption]];
// Return YES to cause the search result table view to be reloaded.
return YES;
}
Any help would be appreciated, thank you for taking the time to read this.
