在应用程序运行时阻止Iphone iOS中的呼叫和短信 [英] Block calls and sms in Iphone iOS while application running

问题描述

使用app时我想阻止所有来电和短信。我怎样才能做到这一点？我知道示例链接 http://tech.ruimaninfo.com/?p=83 。但是代码中有错误。它应该至少在越狱的iPhone上工作。

while using app I want to block all incoming calls and sms. How can I do this? I know example link http://tech.ruimaninfo.com/?p=83. But there are errors in code.It should work at least on jailbroken iphone.

推荐答案

下面是我改编的一些代码来自该网站，并在我的非越狱设备上为我工作：

Below is some code that I've adapted from that website, and works for me on my non jailbroken device:

首先将CoreTelephony.framework添加到您的项目中，然后将其导入您的视图控制器，如下所示： / p>

Firstly add "CoreTelephony.framework" to your project then import it into your view controller like so:

#import <CoreTelephony/CoreTelephonyDefines.h>

接下来，添加以下代码：

Next, add the following code:

extern NSString const *kCTSMSMessageReceivedNotification;
extern NSString const *kCTSMSMessageReplaceReceivedNotification;
extern NSString const *kCTSIMSupportSIMStatusNotInserted;
extern NSString const *kCTSIMSupportSIMStatusReady;

typedef struct __CTCall CTCall;
extern NSString *CTCallCopyAddress(void*, CTCall *);

void * CTSMSMessageSend(id server,id msg);
typedef struct __CTSMSMessage CTSMSMessage;
NSString *CTSMSMessageCopyAddress(void *, CTSMSMessage *);
NSString *CTSMSMessageCopyText(void *, CTSMSMessage *);

int CTSMSMessageGetRecordIdentifier(void * msg);
NSString * CTSIMSupportGetSIMStatus();
NSString * CTSIMSupportCopyMobileSubscriberIdentity();

id CTSMSMessageCreate(void* unknow/*always 0*/,NSString* number,NSString* text);
void * CTSMSMessageCreateReply(void* unknow/*always 0*/,void * forwardTo,NSString *text);

id CTTelephonyCenterGetDefault(void);
void CTTelephonyCenterAddObserver(id, id, CFNotificationCallback, NSString *, void *,int);
void CTTelephonyCenterRemoveObserver(id,id,NSString*,void*);
int CTSMSMessageGetUnreadCount(void);

void * CTCallDisconnect(CTCall *call);

static void callback(CFNotificationCenterRef center, void *observer, CFStringRef name, const void *object, CFDictionaryRef userInfo) {

    NSString *notifyname = (__bridge NSString *)name;

    if ([notifyname isEqualToString:@"kCTCallIdentificationChangeNotification"]) {

        NSDictionary *info = (__bridge NSDictionary *)userInfo;

        CTCall *call = (__bridge CTCall *)[info objectForKey:@"kCTCall"];

        NSString *caller = CTCallCopyAddress(NULL, call);

        NSLog(@"RECEIVED CALL: %@", caller);

        CTCallDisconnect(call);

    }

}

static void signalHandler(int sigraised) {

    printf("\nInterrupted.\n");
    exit(0);

}

在viewDidLoad或其他一些合适的方法中，添加以下内容：

And in viewDidLoad or some other appropriate method, add the following:

id ct = CTTelephonyCenterGetDefault();
CTTelephonyCenterAddObserver(ct, NULL, callback, NULL, NULL, CFNotificationSuspensionBehaviorHold);

sig_t oldHandler = signal(SIGINT, signalHandler);
if (oldHandler == SIG_ERR) {

    printf("Could not establish new signal handler");
    exit(1);

}

printf("Starting run loop and watching for notification.\n");
CFRunLoopRun();

现在这段代码只是一个概念证明，必须扩展以进行错误处理和什么，但你应该明白这一点。

For now this code is merely a proof of concept and would have to be expanded upon for error handling and whatnot, but you should get the idea.
