Searching a custom tableviewCell - objective-c

Question

I want to do a search in a tableview. But in this table view I work with a custom tableview Cell. So for the data part. I select in a view a categorie. Then in the next view I get all the products within this categorie.
I followed a tutorial and implemented all the methods.
This is my function for getting the products.
-(void) fillArrayProducts:(NSString *)cat{
NSMutableString *postString = [NSMutableString stringWithString:kGETProducts];
[postString appendString:[NSString stringWithFormat:#"?%#=%#",#"Pro_cat",cat]];
[postString setString:[postString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSMutableURLRequest *request= [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:postString]];
[request setHTTPMethod:#"POST"];
postConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:postString]];
NSError *error;
json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
arrayProducts = [[NSMutableArray alloc] init];
copyArrayProducts = [[NSMutableArray alloc] init];
arrayProductNaam = [[NSMutableArray alloc] init];
for (int i=0; i<[json count]; i++) {
arrayProduct = [[NSMutableArray alloc] init];
[arrayProduct addObject:[json objectAtIndex:i]];
[arrayProducts addObject:arrayProduct];
[arrayProductNaam addObject:[[[arrayProducts valueForKey:#"Pro_naam"] objectAtIndex:i]objectAtIndex:0]];
[copyArrayProducts addObject:arrayProduct];
}
NSDictionary *productsDict = [NSDictionary dictionaryWithObject:arrayProductNaam forKey:#"Products"];
NSLog(#"%#",arrayProductNaam);
}
No what I'm doing. I have an array 'arrayProducts' in this array I put arrays from 'arrayProduct'. In arrayProduct you can find Pro_id,Pro_naam,Pro_prijs. But I only want to search on Pro_naam. So I fill also an array (arrayProductNaam) with only the products names.
So here is the part were I do my search.
- (void) searchTableView {
NSString *searchText = searchbar.text;
NSMutableArray *searchArray = [[NSMutableArray alloc] init];
for (NSDictionary *dictionary in arrayProductNaam)
{
NSArray *array = [dictionary objectForKey:#"Pro_naam"];
[searchArray addObjectsFromArray:array];
}
for (NSString *sTemp in searchArray)
{
NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch];
if (titleResultsRange.length > 0)
[copyArrayProducts addObject:sTemp];
}
}
I think that it's here were I getting this error.

Answer 1

You are not filling arrayProductNaam with Dictionary. Its filled by NSString. Now, in the searchTableView function you are handling these string members as Dictionaries and hence the problem.

Answer 2

try to NSLog your String Array. so you can get the idea it exist or not

Answer 3

you are trying to get a keyValue from a string not from a dictionary.
