未声明的标识符“MSHookIvar”

Question

在导入substrate.h之后，我继续在一个钩子类的函数中使用MSHookIvar。顺便说一句，我正在尝试从Cygwin编译。我无法编译，出现以下错误：

Tweak.xm:20:16: error: use of undeclared identifier 'MSHookIvar'
    hookedLabel = MSHookIvar<UILabel *>(self, "_textLabel");
                  ^
Tweak.xm:20:27: error: unexpected interface name 'UILabel': expected expression
    hookedLabel = MSHookIvar<UILabel *>(self, "_textLabel");
                             ^
Tweak.xm:20:36: error: expected expression
    hookedLabel = MSHookIvar<UILabel *>(self, "_textLabel");
                                      ^
Tweak.xm:20:38: error: expression result unused [-Werror,-Wunused-value]
    hookedLabel = MSHookIvar<UILabel *>(self, "_textLabel");

这是我的代码：

#import <UIKit/UIKit.h>
#import "substrate.h"
#import "logos/logos.h"

%hook DataView

UILabel *hookedLabel;

-(void)layoutSubviews {
    UILongPressGestureRecognizer *lpg = [[UILongPressGestureRecognizer alloc] initWithTarget: self action:@selector(handleLongPress)];
    [lpg setDelegate:self];
    [lpg setMinimumPressDuration:1];
    [self addGestureRecognizer:lpg];

    hookedLabel = MSHookIvar<UILabel *>(self, "_textLabel");
}

%end

我尝试导入logos.h，但仍然没有任何帮助。

编辑:我意识到我的substrate.h没有MSHookIvar的定义，我该怎么办？

请帮帮忙

我发现了来自googlecode用户networkpx Link的substrate.h

我用我现在的版本替换了它，它似乎可以很好地编译和工作。
