ios - 访问转储 header 的实例变量(iOS)

Question

我想知道类的实例变量“_lastNotificationReceivedBundleIdentifier”的值。 header 是从 iOS 跳板应用程序中转储的。

@interface SBRemoteNotificationServer : NSObject <APSConnectionDelegate> {
    NSMutableDictionary* _bundleIdentifiersToClients;
    NSMutableDictionary* _environmentsToConnections;
    unsigned _lastPlayedAlertSound;
    NSString* _lastNotificationReceivedBundleIdentifier;
}

但是下面的代码不起作用:

%hook SBRemoteNotificationServer
-(void)noteApplicationFinishedLaunching:(id)launching{
    NSLog(@"identifier=%@",_lastNotificationReceivedBundleIdentifier);
    %orig;
}
%end

编译器错误是:

error: ‘_lastNotificationReceivedBundleIdentifier’ was not declared in this scope

如何访问和记录这个 NSString？

Answer 1

您可能会使用 objective-c 运行时功能并查看方法 object_getInstanceVariable(the_object, "_lastNotificationReceivedBundleIdentifier", (void**)&yourPointer);
