How to control multiple arrays when using search in UITableView - ios

Question

I have four array videoName, ActorName, VideoID, ActorID. I combined videoName & ActorName to make a single array "title", and same with VideoID & ActorID to make array "IDs"
In short,
title = ActorName + videoName
IDs = ActorID + VideoID
here is my code,
Tableview Methods
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
return self.searchResults.count;
} else {
return self.title.count;
}
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellID = #"cellID";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
}
cell.backgroundColor = [UIColor clearColor];
cell.textLabel.textColor = [UIColor whiteColor];
cell.imageView.frame = CGRectMake(0,0,32,32);
if (tableView == self.searchDisplayController.searchResultsTableView) {
cell.textLabel.text = [self.searchResults objectAtIndex:indexPath.row];
cell.imageView.image = [UIImage imageNamed:[img objectAtIndex:indexPath.row]];
cell.textLabel.textColor = [UIColor blackColor];
} else {
cell.textLabel.text = [self.title objectAtIndex:indexPath.row];
cell.imageView.image = [UIImage imageNamed:[img objectAtIndex:indexPath.row]];
}
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
}
Search Methods
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"SELF beginswith[c] %#", searchText];
// NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:#"contains[c] %#", searchText];
self.searchResults = [self.title filteredArrayUsingPredicate:predicate];
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex:[self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}
Requirement
Now, first i need to get that which row was selected, actor or Video, secondly actorID or VideoID. It was easy if there was no search bar, because after the search all rows restored again with new data plus rows are populated from "title" not "IDs" so how can i get IDs when user select the row.

Answer 1

create a NSObject subclass for this Item.h and Item.m with 3 properties for name and id like,
in Item.h
typedef enum : NSInteger {
ItemTypeVideo,
ItemTypeActor,
} ItemType;
#interface Item : NSObject
#property (nonatomic, strong) NSString *name;
#property (nonatomic, strong) NSString *itemId;
#property (nonatomic, strong) NSString *imageName;
#property (nonatomic, assign) ItemType itemType;
#end
by above code we are creating a class whose object can hold values defined in properties.
since an object of Item class can hold name, id, image name and type of video/actor, we can set these values of 1 video/actor to one object.
here we have multiple vides/actor elements, so we need an array of Item objects each one holding details of one video/actor like
Item *videoItem = [[Item alloc] init];
videoItem.name = videoName;
videoItem.itemId = videoId;
videoItem.imageName = videoImageName;
videoItem.itemType = ItemTypeVideo;
create for all items in videoName array and actor array. Add both this to a common dataArray like,
[self.dataArray addObejct:videoItem];
and
Item *actorItem = [[Item alloc] init];
actorItem.name = actorName;
actorItem.itemId = actorId;
actorItem.imageName = actorImageName;
actorItem.itemType = ItemTypeActor;
similarly [self.dataArray addObejct:actorItem];
and in cellForRowAtIndexPath:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//other stuff
Item *currentItem = nil;
if (tableView == self.searchDisplayController.searchResultsTableView) {
currentItem = [self.searchResults objectAtIndex:indexPath.row];
} else {
currentItem = [self.dataArray objectAtIndex:indexPath.row];
}
cell.textLabel.text = currentItem.name;
cell.imageView.image = [UIImage imageNamed:currentItem.imageName];
//rest stuff
}
finally in search,
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"name beginswith[c] %#", searchText];
// NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:#"contains[c] %#", searchText];
self.searchResults = [self.dataArray filteredArrayUsingPredicate:predicate];
}
So in any case,
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Item *currentItem = nil;
if (tableView == self.searchDisplayController.searchResultsTableView) {
currentItem = [self.searchResults objectAtIndex:indexPath.row];
} else {
currentItem = [self.dataArray objectAtIndex:indexPath.row];
}
//all details will be in currentItem
}
