Question

我使用首选项包控制器类保存了一些数据。我想与它的 tweak文件分享它，即我希望跳板能够传递首选项包以便从中获取一些数据，反之亦然。我试图使用Libobjcipc - 正如其文档中所述：

libobjcipc是一个开发人员库，为越狱iOS提供进程间通信（在app和SpringBoard之间）。它处理SpringBoard和app进程之间的套接字连接......

我曾尝试从tweak发送消息，但无法弄清楚如何在我的首选项捆绑控制器中接收传入消息。我知道方法[OBJCIPC registerIncomingMessageFromSpringBoardHandlerForMessageName:handler:]将用于此目的。但是我在哪里使用它？希望得到一些积极的回应...谢谢..

修改

我在@creker建议后尝试使用CFNotificationCenter。我可以发送通知，但我的调整无法接收，因此不会执行回调方法callBackNotification。这是更改的代码：

Tweak.xm

//at the end of tweak file

static void callBackNotification(CFNotificationCenterRef center,void *observer,CFStringRef name,const void *object,CFDictionaryRef userInfo)
{
NSLog(@"Notification received!");
}

%ctor
{

    NSLog(@"Init cqlled!"); //this piece of code called successfully
    //Register for the change notification
    CFNotificationCenterRef r = CFNotificationCenterGetDarwinNotifyCenter();
    CFNotificationCenterAddObserver(r, NULL, reloadPrefsNotification, CFSTR("ccom.identifier.message"), NULL, CFNotificationSuspensionBehaviorDeliverImmediately);
}

偏好捆绑控制器

@interface SettingsListController: PSListController {
}
@end

@implementation SettingsListController
- (id)specifiers {
    if(_specifiers == nil) {
        _specifiers = [[self loadSpecifiersFromPlistName:@"JRLockerSettings" target:self] retain];
    }

    return _specifiers;
}

-(void) postNotification()
{
CFNotificationCenterRef center = CFNotificationCenterGetLocalCenter();

// post a notification
CFDictionaryKeyCallBacks keyCallbacks = {0, NULL, NULL, CFCopyDescription, CFEqual, NULL}; 
CFDictionaryValueCallBacks valueCallbacks  = {0, NULL, NULL, CFCopyDescription, CFEqual};
CFMutableDictionaryRef dictionary = CFDictionaryCreateMutable(kCFAllocatorDefault, 1, 
                                                              &keyCallbacks, &valueCallbacks);
CFDictionaryAddValue(dictionary, CFSTR("identifier"), CFSTR("value"));
CFNotificationCenterPostNotification(center, CFSTR("com.identifier.message"), NULL, dictionary, TRUE);
CFRelease(dictionary);
}

@end
