目标C语言 是iPhone自动释放为c数组工作

将自动释放释放我的非对象c数组?我很好奇，因为也许只有对象知道它们的引用计数?下面是我的代码:

-(int *)getCombination{
    int xIndex = arc4random() % [self._num1 count] + 1;
    int yIndex = arc4random() % [self._num2 count] + 1;
    int *combination;
    combination[0] = [[self._num1 objectAtIndex:xIndex]intValue];
    combination[1] = [[self._num2 objectAtIndex:yIndex]intValue];
    return combination;
}

这是我的main()函数:

int main(int argc, char *argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([YYAAppDelegate class]));
    }
}

所以自动释放只适用于对象，还是会从getCombination释放我的c数组?

编辑:因为答案是否定的，自动释放不工作的c数组/指针，我使用以下代码使用nsarray代替:

#import <Foundation/Foundation.h>
@interface Multiplication : NSObject
@property (strong, nonatomic) NSMutableArray *_combinations;
-(id)initArrays;
-(NSArray *)getCombination;
@end
#import "Multiplication.h"
@implementation Multiplication
@synthesize _combinations;
-(void)initializeArray{
    self._combinations = [[NSMutableArray alloc]init];
    for (int i = 1; i <= 10; i++) {
        for (int j = 1; j <= 10; j++) {
            NSNumber *x = [NSNumber numberWithInt:i];
            NSNumber *y = [NSNumber numberWithInt:j];
            [self._combinations addObject:[NSArray arrayWithObjects:x, y, [NSNumber numberWithInt:([x intValue] * [y intValue])], nil]];
        }
    }
}
-(NSArray *)getCombination{
    if ([self._combinations count] == 0) {
        [self initializeArray];
    }
    int index = arc4random() % [self._combinations count];
    NSArray *arr = [self._combinations objectAtIndex:index];
    [self._combinations removeObjectAtIndex:index];
    return arr;
}
-(id)initArrays{
    self = [super init];
    if (self) {
        [self initializeArray];
    }
    return self;
}
@end

顺便说一下，这个函数应该提供一种方法来随机显示10X10乘法表中的每个组合，并在所有组合都显示并显示相同次数时重新开始。
