[Solved] count NSArray from another class

by


Not the best naming convention but take a look at the following example. You declare a public property in the Questions object and access it from the controller after you initialised a new object there. You may consider declaring it readonly and set it to readwrite in the private interface extension.

Questions.h

#import <Foundation/Foundation.h>
@interface Questions : NSObject
@property NSMutableArray *questions;

@end

Questions.m

#import "Questions.h"
@implementation Questions
-(id) init { 
  if (self = [super init]) {
    _questions = @[4,5,6];
  }
  return self;
}
@end

ViewController.m

#import "Questions.h"
-(void)generateRandomQuestionOrder {
    Questions *theQuestions = [[Questions alloc] init];
    NSLog(@"%@", [theQuestions.questions description]); 
}
