在使用应用程序时阻止Iphone iOS中的呼叫和短信，同时运行应用程序

Question

我想阻止所有来电和短信。我怎样才能做到这一点？我知道例子链接http://tech.ruimaninfo.com/?p=83。但是在代码中存在错误。它应该至少在越狱iphone上工作。

下面是一些代码，我已经适应从该网站，并为我工作我的非越狱的设备上：

首先添加“CoreTelephony.framework”到您的项目，然后将其导入到你的视图控制器，像这样：

#import <CoreTelephony/CoreTelephonyDefines.h> 

接下来，添加以下代码：

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); 

} 

而在viewDidLoad中或一些其它合适的方法中，添加以下：

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(); 

现在这个代码仅仅是一个概念证明和将会对错误处理和诸如此类的东西进行扩展，但你应该明白我的意思。
