我已经解密了一些头文件，这是我想从中挂钩一些 ivars 的头文件。

#import <XXUnknownSuperclass.h> // Unknown library
#import "InAppNotificationMessageViewDelegate.h"
#import "FBMSessionClassProvidable.h"

@class InAppNotificationContainerView, ProjectGatingChecker, FBMViewProvider, InAppNotificationBadgeCounter, FBMBeeperListFetcher;
@protocol FBMNavigator, FBProvider, FBMAppProperties;

@interface InAppNotificationManager : XXUnknownSuperclass <InAppNotificationMessageViewDelegate, FBMSessionClassProvidable> {
    id<FBMNavigator> _navigator;
    FBMBeeperListFetcher* _beeperListFetcher;
    InAppNotificationBadgeCounter* _badgeCounter;
    FBMViewProvider* _notificationMessageViewProvider;
    InAppNotificationContainerView* _notificationContainerView;
    FBMViewProvider* _notificationContainerViewProvider;
    id<FBMAppProperties> _appProperties;
    ProjectGatingChecker* _gatingChecker;
    id<FBProvider> _rootNavControllerProvider;
    id<FBProvider> _threadViewControllerProvider;
}
@property(retain, nonatomic) id<FBMAppProperties> appProperties;
@property(retain, nonatomic) id<FBProvider> threadViewControllerProvider;
@property(retain, nonatomic) id<FBMNavigator> navigator;
@property(retain, nonatomic) ProjectGatingChecker* gatingChecker;

所以我想挂钩 gatingChecker ivar，我使用了 logify 并创建了这些行：

%hook InAppNotificationManager


- (void)setGatingChecker:(ProjectGatingChecker* )gatingChecker { %log; %orig; }
- (ProjectGatingChecker* )gatingChecker { %log; ProjectGatingChecker*  r = %orig; NSLog(@" = %@", r); return r; }


%end

当我尝试编译它时，我得到：

Tweak.xm:9: error: ‘ProjectGatingChecker’ has not been declared
Tweak.xm:9: error: ‘ProjectGatingChecker’ has not been declared
Tweak.xm:9: error: expected initializer before ‘*’ token

您使用 MSHookIvar 挂钩实例变量

ProjectGatingChecker *myGatingChecker = MSHookIvar<ProjectGatingChecker *>(self, "_gatingChecker");

您现在可以使用 myGatingChecker，它是一个指向挂钩变量的指针。
