- My solution works on iOS 7
- Your bundle id is wrong, it should be
com.apple.imservice.sms
. I've posted SMS service directory path (/System/Library/Messages/PlugIns/SMS.imservice/
). In there you can findInfo.plist
which contains bundle id of the plugin -com.apple.imservice.sms
. - You are hooking the wrong method. It's
IMDService -(void)loadServiceBundle
, without arguments. Then you can use[[self bundle] bundleIdentifier]
to get bundle id. Also, don't forget to call original implementation ofloadServiceBundle
before you hook_processReceivedMessage:
or even check for bundle id. Original implementation actually loads the plugin, so calling it should be the first thing you do.
Blocking incoming sms in iOS 7

Вопрос
I want to write a tweak for jailbroken devices that blocks messages from a phone number(in iOS 7). First I used the second answer of creker in this link for writing the tweak. Here is my code:
#import <substrate.h>
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <libkern/OSAtomic.h>
#import "CTMessage.h"
#import "CTMessageCenter.h"
id(*_processReceivedMessage_orig)(id, SEL, CTMessage*) = NULL;
id _processReceivedMessage_hooked(id self, SEL _cmd, CTMessage* msg);
%hook IMDService
-(void)loadServiceBundle:(NSBundle*)bundle
{
if ([[bundle bundleIdentifier] isEqualToString:@"com.apple.SMSPlugin"] && [bundle isLoaded]) // not sure if the bundle identifier is correct!
{
MSHookMessageEx(objc_getClass("SMSServiceSession"),
@selector(_processReceivedMessage:),
(IMP)_processReceivedMessage_hooked,
(IMP*)&_processReceivedMessage_orig);
}
}
%end
id _processReceivedMessage_hooked(id self, SEL _cmd, CTMessage* msg)
{
NSObject<CTMessageAddress>* phonenumber = [msg sender];
NSString *senderNumber = (NSString*) [phonenumber canonicalFormat]; // sender number
if ([senderNumber isEqualToString:@"+012345678910"])
[[CTMessageCenter sharedMessageCenter] acknowledgeIncomingMessageWithId:[msg messageId]];
else
return _processReceivedMessage_orig(self, _cmd, msg);
}
and my plist file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Filter</key>
<dict>
<key>Bundles</key>
<array>
<string>com.apple.imagent</string>
</array>
</dict>
</dict>
</plist>
The main problem is that loadServiceBundle
never gets hooked and my function never gets called! If I install the tweak on the iPhone, nothing happens when mobile has incoming sms and message alert comes. I myself think that the problem is I’m writing for iOS 7 but the question is for iOS 6. If the problem is this, could you tell what should I have to do?
Another question that I have is in the loadServiceBundle
method. As you can see in the written code, I don’t exactly know which bundle identifier should I filter. Please tell me if I’ve chosen the right bundle identifier.
I would be glad to tell me if I have any other problems in my code.
