How would I set each individual row in cellForRowAtIndexPath to the results of an array populated by a Fetch Request? (Fetch Request made when button is pressed.)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
// ... set up cell code here ...
cell.textLabel.text = [results objectAtIndex:indexPath valueForKey:@"name"];
}
warning: 'NSArray' may not respond to '-objectAtIndexPath:'
Edit:
- (NSArray *)SearchDatabaseForText:(NSString *)passdTextToSearchFor{
NSManagedObject *searchObj;
XYZAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
NSManagedObjectContext *managedObjectContext = appDelegate.managedObjectContext;
NSFetchRequest *request = [[NSFetchRequest alloc] init];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"name contains [cd] %@", passdTextToSearchFor];
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Entry" inManagedObjectContext:managedObjectContext];
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:NO];
NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil];
[request setSortDescriptors:sortDescriptors];
[request setEntity: entity];
[request setPredicate: predicate];
NSError *error;
results = [managedObjectContext executeFetchRequest:request error:&error];
// NSLog(@"results %@", results);
if([results count] == 0){
NSLog(@"No results found");
searchObj = nil;
self.tempString = @"No results found.";
}else{
if ([[[results objectAtIndex:0] name] caseInsensitiveCompare:passdTextToSearchFor] == 0) {
NSLog(@"results %@", [[results objectAtIndex:0] name]);
searchObj = [results objectAtIndex:0];
}else{
NSLog(@"No results found");
self.tempString = @"No results found.";
searchObj = nil;
}
}
[tableView reloadData];
[request release];
[sortDescriptors release];
return results;
}
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{
textToSearchFor = mySearchBar.text;
results = [self SearchDatabaseForText:textToSearchFor];
self.tempString = [myGlobalSearchObject valueForKey:@"name"];
NSLog(@"results count: %d", [results count]);
NSLog(@"results 0: %@", [[results objectAtIndex:0] name]);
NSLog(@"results 1: %@", [[results objectAtIndex:1] name]);
}
@end
Console prints:
