Pre-loading string into search bar & searching from segue

Question

Question is similar to this one: Setting searchBar.text in view did load

I have my keyword from V1 passing to V2 without issues; I'm trying to set it as search bar text & search from previous segue.

String is called searchText.

I've tried

    self.searchBar.text = self.searchText;

in viewWillAppear & viewDidLoad of V2 but nothing is showing up in my search bar.

How can I get my searchText into the search bar and filtering my table after segue from V1 to V2?

Are you sure the string is not empty before setting it as searchbar text?

The following code works perfectly for me.

@interface ViewController (){
    NSString *searchText;
}

@property (weak, nonatomic) IBOutlet UISearchBar *searchBar;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    searchText = @"I love ice cream!";
}

-(void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    self.searchBar.text = searchText;
}

This is a method how you can check if the string is empty:

self.searchBar.text = (searchText == nil || searchText == (id)[NSNull null] || searchText.length == 0) ? @"To bad, an empty string" : searchText;
