Instance variable 'variable' accessed in class method error

Question

I have a variable declared in the header file :

@interface

int _nPerfectSlides;

and

@property (nonatomic, readwri         


        

Answer 1

1. For + (void)hit:Only have access to the self object.

--Step 1: Remove follwing line from header file

@property (nonatomic, readwrite) int _nPerfectSlides;

--Step 2:

• Add int _nPerfectSlides in your class file globally..
• That means declare before @implementation

Eg: In .m File

#import "Controller.h"
int _nPerfectSlides // Add like this before @implementation

@implementation Controller

2. For - (void)hit:Only have access to the instance methods
