如何/在何处释放Objective C中的全局变量？

Question

我已经完成了以下问题.

目标C - 你在哪里解除全局静态变量？

但问题与静态变量有关.它有一些不同的情况,然后我的.

我在应用程序中有以下代码.

//.h file
#import "cocos2d.h"
#import "something.h"
#import "myLayer.h"
#import "LayerData.h"

// i have taken this variables as global 
// because two different classes are simultaneously accessing it

myLayer *myCurrentLayer;
LayerData *boxLayerData[10][12];

@interface one
    // my class definition here
@end

@interface two
    // my second class definition here
@end


//------------------------------------------------
@implementation one
    // my class constructor here.
    -(id)init{
        myCurrentLayer=[[myLayer alloc] init];
        // boxLayerData is initialized with objects
    }
@end

@implementation two
    // second class constructor
    -(id)init{
        [myCurrentLayer setPosition:ccp(10,20)];
        [self schedule something for movements];
    }
@end
//------------------------------------------------

好.我的困惑是"如何释放120大小的"LayerData*boxLayerData [10] [12];"数组？"

同样的答案适用于全局,因为它适用于静态.如果您需要整个应用程序生命周期的数据,请保持原样,并在应用程序终止时由操作系统回收内存.如果需要在应用程序执行期间释放对象,则可以遍历数组并在每个对象上调用release.

像这样的东西:

for (int i = 0; i < 10; i++)
{
  for (int j = 0; j < 12; j++)
  {
     LayerData *data = boxLayerData[i][j];
     [data release], data = nil;
  }
}
