Question

I am getting the “Subscripted value is neither array nor pointer” error on a boolean made from another class that gets allocated in another. After looking up lots of reasons for getting this error, I’m not sure how I can relate it to mine. I’m using the Cocos2D library, but I don’t think it has to do with that.

In another class this is my interface with a property. Just calling it ClassA for this example:

#import <Foundation/Foundation.h>
@interface ClassA : NSObject {
@public

    @public
        BOOL _deactivateLabelToggle;

}

@property(nonatomic, assign) BOOL deactivateLabelToggle;

.m

#import "ClassA.h"

@implementation ClassA
@synthesize deactivateLabelToggle = _deactivateLabelToggle;

BOOL _deactivateLabelToggle[100];

-(id) init{
    self = [super init];
    if (!self) {
        return nil;
    }

    return self;
}

- (void) dealloc{

    [super dealloc];

}   


@end

My main class header

#import "ClassA.h"
@class ClassA;

@interface MainClass : CCLayer {

    ClassA *classA;
}


@property(nonatomic, retain) ClassA *classA;

@end

MainClass.m

#import "MainClass.h"

@implementation MainClass

@synthesize classA;

-(id) init {

    if( (self=[super init] )) {

          classA = [[ClassA alloc] init];

          classA.deactivateLabelToggle[i] = 0; // <---- Error here

    }
    return self;
}

Answer 1

Your deactivateLabelToggle property with this declaration in ClassA:

@property(nonatomic, assign) BOOL deactivateLabelToggle;

that you access on the // <---- Error here line is indeed neither array nor pointer. Simple BOOL variables can’t be subscripted.

If you meant to reference the file-global BOOL array in your ClassA.m file, you can’t do it with a synthesized property (and the type needs to be BOOL* instead of BOOL).
