Xcode UISearchBar Code Implementation - ios

Question

I'm currently working on a project where I have to filter through a NSArray (displayed in an UITableView). Problem is, there is neither a XIB file nor a storyboard.
My question is (I already got the predicate and search method et.c set up), how do I get the SearchBar to show up in my program only using code - and ofc I need to be able to work with it.
I'd be really glad about some help with this issue, because every tutorial I found either uses storyboards or xibs :(
Thank you very much up front!
Btw those are the two methods I got so far concerning the search bar, the TableView is also set up already.
-(void) filterContentForSearchText:(NSString *)searchText scope:(NSString *)scope {
NSPredicate *predicate = [NSPredicate predicateWithFormat:#"SELF contains[c] %#", searchText];
self.searchResults = [self.array filteredArrayUsingPredicate:predicate];
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {
[self filterContentForSearchText:searchString scope:[[self.searchDisplayController.searchBar scopeButtonTitles]objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];
return YES;
}

Answer 1

You can do something like this:
In your .h add this:
#property (nonatomic,strong) UISearchBar *searchBar;
Add this in your viewDidLoad method
self.searchBar = [[UISearchBar alloc]init];
self.searchBar.frame = CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height);
self.searchBar.delegate = self;
//Customize the searchBar
[self.view addSubview:self.searchBar];
And whenever you want to search, press the search button within the keyboard. A delegate will be called when you do this. Like so,
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{
[searchBar resignFirstResponder];
//Do some search
}
You can access the entered the text using the searchBar.text property. I am assuming that you have implemented the relevant protocols.

If there is no XIB file and no Storyboard, it is initiated somewhere in the code (probably in the viewDidload) looking something like this.
UISearchBar *searchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 0, 100, 20)];
searchBar.delegate = self;
//etc..
Now first add a property in the interface
#property (nonatomic, strong)UISearchBar *searchBar;
And change this line in the viewDidLoad:
self.searchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 0, 100, 20)];
Now you can us self.searchBar anywhere in your code.
Edit:
And don't forget to add this to the interface if it wasn't already:
#interface ViewController () <UISearchBarDelegate, UISearchDisplayDelegate>
