类方法错误中访问实例变量“变量" [英] Instance variable 'variable' accessed in class method error

问题描述

我在头文件中声明了一个变量:

I have a variable declared in the header file :

@interface

@interface

int _nPerfectSlides;

和

@property (nonatomic, readwrite) int _nPerfectSlides;

，我有一个在标头中声明的方法:

and I have a method that I declared in the header :

+ (void) hit;

该方法中包含以下代码:

The method has the following code in it :

+ (void) hit {
    NSLog(@"hit");
    _nPerfectSlides = 0;
    [_game showHit];
}

现在由于某种原因，我收到错误在类方法中访问实例变量'_nPerfectSlides'"错误，看来我无法访问该方法内部的任何变量.我在做什么错了?

now for some reason I get the error "Instance variable '_nPerfectSlides' accessed in class method" error and it seems like I cant access any variables inside the method. What am I doing wrong?

推荐答案

如果您打算将此方法作为实例方法，请将+更改为-.

If you meant to make this an instance method, change that + to -.
