Too many arguments to method call, expected 1, have 2?(Xcode)

Question

There are many other similar questions to this one, but there is a lack of answers and they vary for each project. I have this error 'Too many arguments to method call, expected 1, have 2?' But on the previous arrays that I used this error did not occur? it could be a problem with the code but i am unsure? I have went through searching for other errors that may influence it, but have had no luck. Below is my coding,

#import "MenuViewController.h"
#import "ECSlidingViewController.h"

@interface MenuViewController ()

@property (strong, nonatomic) NSArray *menu;
@property (strong, nonatomic) NSArray *section1;
@property (strong, nonatomic) NSArray *section2;
@property (strong, nonatomic) NSArray *section3;


@end

@implementation MenuViewController

@synthesize menu, section1, section2, section3;

}

    [super viewDidLoad];

    // self.navigationItem.rightBarButtonItem = self.editButtonItem;

    self.section1 = [NSArray arrayWithObjects:@"News Feed", @"Buy Shares", @"Sell Shares", nil];

Any help would be much appreciated. Thanks. The error appears where i have placed '***'

Answer 1

[[NSArray alloc] initWithObjects:@"Leaderboard", nil];

Answer 2

It would have been nice if you had indicated which line was causing problems, but I think I found it anyway:

[NSArray arrayWithObject:@"Leaderboard", nil];

arrayWithObject only expects an object, not a comma-separated array of objects. Use the following instead:

[NSArray arrayWithObject: @"Leaderboard"];

Or, to be more consistent with the surrounding code, use

[NSArray arrayWithObjects: @"Leaderboard", nil];
