Description :

A lightweight cross-process communication tool for sending and receiving messages on iOS 15 & 16 for rootless jailbreaks

What does it do ?

• Send Messages : Send a message with a value to another process .
• Send Messages With Reply : Send a message with a value to other processes and get an instant reply from those processes .

How does it work ?

This tool relies on the CFNotificationCenterGetDistributedCenter() function from macOS. It is also compatible with iOS. The primary functionality of this func is to send cross-process notifications.

Given the restrictions on CPDistributedMessagingCenter, I have implemented its methods using the CFNotificationCenterGetDistributedCenter() function. This approach ensures that cross-process communication is possible even under the limitations imposed by the platform.

By leveraging this functionality, developers can efficiently send notifications across different processes, enhancing the IPC capabilities of their tweaks.

Header file :

typedef enum CrossOverIPCServiceType : CFIndex {

    SERVICE_TYPE_SENDER,
    SERVICE_TYPE_LISTENER

} CrossOverIPCServiceType;


@interface CrossOverIPC : NSObject 

+ (instancetype) centerNamed:(NSString *)serviceName type:(CrossOverIPCServiceType)type;
- (void) registerForMessageName:(NSString *)msgName target:(id)target selector:(SEL)sel;
- (void) sendMessageName:(NSString *)msgName userInfo:(NSDictionary *)userInfo;
- (NSDictionary *) sendMessageAndReceiveReplyName:(NSString *)msgName userInfo:(NSDictionary *)userInfo;

@end 

How to use it ?

For example ~ Getting UDID from SpringBoard to App ..

• Add CrossOverIPC.h to your project .

#import "CrossOverIPC.h"

~ SpringBoard :

  #define _serviceName @"com.cm90.crossOverIPC"

  CrossOverIPC *crossOver = [objc_getClass("CrossOverIPC") centerNamed:_serviceName type:SERVICE_TYPE_LISTENER];
  [crossOver registerForMessageName:@"UDID_Getter" target:self selector:@selector(handleMSG:userInfo:)];

Target method :

-(NSDictionary *) handleMSG:(NSString *)msgId userInfo:(NSDictionary *)userInfo {

	if ([(NSString *)userInfo[@"action"] isEqual:@"getUDID"])
	  return @{@"UDID":[UIDevice.currentDevice sf_udidString] ?: @"No udid"};
	
	return @{};
}

~ App :

    #define _serviceName @"com.cm90.crossOverIPC"

    CrossOverIPC *crossOver = [objc_getClass("CrossOverIPC") centerNamed:_serviceName type:SERVICE_TYPE_SENDER];
    NSDictionary *dict = [crossOver sendMessageAndReceiveReplyName:@"UDID_Getter" userInfo:@{@"action":@"getUDID"}];
    CLog(@"[+] UDID : %@",dict[@"UDID"]);

Important :

• ServiceName must be the same in [Poster] and [Client] .
