Question

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。但是代码中存在错误。至少应该使用越狱的iphone。

以下是我从该网站改编的一些代码，并且在我的非越狱设备上为我工作：

首先将“CoreTelephony.framework”添加到项目中，然后将其导入到视图控制器中，如下所示：

#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);

}

在viewDidLoad或其他一些适当的方法中，添加以下内容：

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();

现在这段代码仅仅是一个概念证明，必须扩展为错误处理等等，但你应该明白这一点。
