目标 C 中的全局变量 [英] Global Variables in Objective C

问题描述

我有一个计数器，我用它来获取该计数器索引处的对象，我需要在另一个类中访问它.

Objective C 中是如何声明静态变量的?

解决方案

嗨 alJaree，
您在您的类的实现中声明了一个静态变量，并通过静态访问器启用对它的访问:<代码><预>some_class.h:@interface SomeClass {...}+ (int) 计数器；@结尾some_class.m:@implementation SomeClass静态整数计数器；+ (int)counter { 返回计数器；}@end

I have a counter which I use to get an object at that counters index and I need to access it in another class.

How are static variables declared in Objective C?

解决方案

Hi alJaree,
You declare a static variable in the implementation of Your class and enable access to it through static accessors:

some_class.h:
@interface SomeClass {...}
+ (int)counter;
@end

some_class.m: 
@implementation SomeClass
static int counter;
+ (int)counter { return counter; }
@end
