Receiver'ClassName'是一个前向类，相应的@interface可能不存在 [英] Receiver 'ClassName' is a forward class and corresponding @interface may not exist

问题描述

我目前正试图在UIPickerView.subviews中找到 UIPickerTable ...所以我循环执行 isKindOfClass：[UIPickerTable class] ....哪个有效......但是由于UIPickerTable的标题没有公开，我得到一个警告，接收者'UIPickerTable'是一个正向类，相应的@interface可能不存在'

Im currently trying to find a UIPickerTable within the UIPickerView.subviews ... so i loop through and do isKindOfClass:[UIPickerTable class] .... which works.. but because the header of UIPickerTable isn't exposed i get a warning that "receiver 'UIPickerTable' is a forward class and corresponding @interface may not exist'

为了能够编译我做@class UIPickerTable，显然它想让我#include它。

In order to even be able to compile I do @class UIPickerTable, and obviously it want's me to #include it.

我想知道是否有办法绕过这个警告。

I'm wondering if there's a way to get around seeing this warning.

TIA！

推荐答案

我认为你不能用编译器选项来抑制那个警告。你可以通过简单地为类创建自己的头文件来消除它，包含：

I don't think that you can suppress that warning with a compiler option. You could make it go away by simply creating your own header file for the class, containing:

@interface FacesViewController : NSObject {
}

我认为不用说你的申请表了结束UIKit类的内部结构可能不是最好的策略。据推测，你有充分的理由在UIPicker里面捣乱......

I suppose it goes without saying that having your application depend on the internal structure of a UIKit class is probably not the best strategy. Presumably you have a good reason for mucking about inside the UIPicker...
