Array not being passed from tableview to view controller through Delegate - ios

Question

I am trying to copy the array from tableview controller to view controller. I have checked the code multiple times and it seems to be okay.
//Delegate class
#import <UIKit/UIKit.h>
#protocol Category <NSObject>
#required
-(void) delegateMethodForCategory : (NSMutableArray *) arrayOfCategory;
#end
#interface Categories : UIViewController <UITableViewDelegate,UITableViewDataSource>
#property (nonatomic) id<Category> delegate;
#property (nonatomic,strong) NSArray *sports;
#property (strong, nonatomic) IBOutlet UITableView *tableview;
#property (nonatomic,strong) NSMutableArray *selectedIndexes;
#end
//Delegate methods
#import "Categories.h"
#interface Categories ()
{
NSMutableArray *array ;
}
#end
#implementation Categories
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
_sports= [[NSArray alloc] initWithObjects: #"Baseball", #"Soccer", #"Hockey",
#"Other",nil];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return _sports.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
array = [[NSMutableArray alloc]init];
// Configure the cell...
cell.textLabel.text=[self.sports objectAtIndex:indexPath.row];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
NSString *cellText = selectedCell.textLabel.text;
if([tableView cellForRowAtIndexPath:indexPath].accessoryType==UITableViewCellAccessoryNone)
{ [tableView cellForRowAtIndexPath:indexPath].accessoryType=UITableViewCellAccessoryCheckmark;
[array addObject:cellText];
}else if([tableView cellForRowAtIndexPath:indexPath].accessoryType==UITableViewCellAccessoryCheckmark){
[tableView cellForRowAtIndexPath:indexPath].accessoryType=UITableViewCellAccessoryNone;
[array removeObject:cellText];
}
}
- (IBAction)doneButton:(id)sender {
[self.delegate delegateMethodForCategory:array];
[self dismissViewControllerAnimated:YES completion:nil];
}
#end
#import <UIKit/UIKit.h>
#import "Categories.h"
#interface ActivityCreator : UIViewController <UIPopoverPresentationControllerDelegate, Category>
#property (nonatomic) Categories *requestClass;
#property (nonatomic,strong) NSMutableArray *arrayOfSports;
#end
//This class implements delegate
import "ActivityCreator.h"
#interface ActivityCreator ()
#end
#implementation ActivityCreator
- (void)viewDidLoad {
[super viewDidLoad];
[self settingUp];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller{
return UIModalPresentationNone;
}
-(void)settingUp{
_requestClass = [[Categories alloc]init];
self.requestClass.delegate = self;
}
#pragma mark - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if([segue.identifier isEqualToString:#"hubabuba"]){
Categories *pop = (Categories *)segue.destinationViewController;
pop.modalPresentationStyle = UIModalPresentationPopover;
pop.popoverPresentationController.delegate = self;
}
}
-(void) delegateMethodForCategory : (NSMutableArray *) arrayOfCategory {
_arrayOfSports = arrayOfCategory;
NSLog(#"%#",_arrayOfSports);
}
Any guidance where I am doing wrong will be of great help. Have been stuck on this for a while.
The delegate method is not being called at all.
Thanks

Set the delegate of Categories class in prepareForSegue method instead of setting in settingUp method.
Write
pop.delegate = self;
In prepareForSegue method.
