I'm trying to get the caller number (for jailbroken devices) with this code:
extern CFTypeRef CTCallCopyName(void*, CTCall* call);
NSLog(#"%#", CTCallCopyName(NULL, (CTCall*)call));
I receive the error:
"CTCallCopyName(void*, CTCall*)", referenced from:
ld: symbol(s) not found for architecture armv6
I have Core Telephony linked with my project.
Maybe my prototype is wrong... i don't know. Any ideas?
Xcode 3, sdk 4
If you're calling this API in a .mm file, you have to declare it like extern "C" void foo(void); As far as I know, on iOS 5 ~ 7, you should use CTCallCopyAddress instead, the prototype is:
extern "C" CFStringRef CTCallCopyAddress(CFAllocatorRef, CTCallRef);
Notice that the second arg is a CTCallRef rather than a CTCall, which means you can't send it CTCall class methods (although some of them work). Besides linking CoreTelephony.framework, you can also load this symbol dynamically, as shown below:
static CFStringRef (*CTCallCopyAddress)(CFAllocatorRef, CTCallRef);
void Foo(CTCallRef call)
{
void *libHandle = dlopen("/System/Library/Frameworks/CoreTelephony.framework/CoreTelephony", RTLD_LAZY);
CTCallCopyAddress = (CFStringRef (*)(CFAllocatorRef, CTCallRef))dlsym(libHandle, "CTCallCopyAddress");
NSString *address = (NSString *)CTCallCopyAddress(kCFAllocatorDefault, call);
NSLog(#"The caller's address is %#", address);
[address release];
dlclose(libHandle);
}
BTW, I can't get CTCallCopyName to work in SpringBoard on iOS 5, haven't figured it out or tried on other systems yet. Hope this information helps!
EDIT: Just give it another try on iOS 5, CTCallGetID is the right function to get the caller ID in the addressbook, whose prototype is ABRecordID CTCallGetID(CTCallRef). iOS 6 and 7 are possibly the same.

I have tried the accepted answer of
How to get IMEI on iPhone?
but I got an empty string.
I saw somebody suggested to use CoreTelephony framework,
but I am not sure how to use it to obtain the IMEI.
Any suggestion on how to use this private API?
NOTE: this does not work anymore!
Haven't tested on any new iOS.
You have to add CoreTelephony.h to your project.
Make sure the header has
int * _CTServerConnectionCopyMobileEquipmentInfo (
struct CTResult * Status,
struct __CTServerConnection * Connection,
CFMutableDictionaryRef * Dictionary
);
Then you can try this code:
#import "CoreTelephony.h"
void getImei() {
struct CTResult it;
CFMutableDictionaryRef kCTDict;
conn = _CTServerConnectionCreate(kCFAllocatorDefault, ConnectionCallback,NULL);
_CTServerConnectionCopyMobileEquipmentInfo(&it, conn, &kCTDict);
NSLog (# "kCTDict is %#", kCTDict);
CFStringRef meid = CFDictionaryGetValue(kCTDict, CFSTR("kCTMobileEquipmentInfoMEID"));
NSLog (# "kCTMobileEquipmentInfoMEID is %#", meid);
CFStringRef mobileId = CFDictionaryGetValue(kCTDict, CFSTR("kCTMobileEquipmentInfoCurrentMobileId"));
NSLog (# "kCTMobileEquipmentInfoCurrentMobileId is %#", mobileId);
}
Here's the CoreTelephony.h
You can check my example project.
Note: I don't think the code works on the simulator and your app might get rejected.
I'm trying to write a password encryption function into my app, following this article.
I wrote a function that runs the CCCalibratePBKDF function and outputs the number of rounds.
const uint32_t oneSecond = 1000;
uint rounds = CCCalibratePBKDF(kCCPBKDF2,
predictedPasswordLength,
predictedSaltLength,
kCCPRFHmacAlgSHA256,
kCCKeySizeAES128,
oneSecond);
This works perfectly, but when I try to implement the next part it all goes wrong.
I can start writing the CCKeyDerivationPBKDF function call and it auto-completes the function and all the parameters. As I go through filling it in all the parameters are also auto-completed.
- (NSData *)authenticationDataForPassword: (NSString *)password salt: (NSData *)salt rounds: (uint) rounds
{
const NSString *plainData = #"Fuzzy Aliens";
uint8_t key[kCCKeySizeAES128] = {0};
int keyDerivationResult = CCKeyDerivationPBKDF(kCCPBKDF2,
[password UTF8String],
[password lengthOfBytesUsingEncoding: NSUTF8StringEncoding],
[salt bytes],
[salt length],
kCCPRFHmacAlgSHA256,
rounds,
key,
kCCKeySizeAES128);
if (keyDerivationResult == kCCParamError) {
//you shouldn't get here with the parameters as above
return nil;
}
uint8_t hmac[CC_SHA256_DIGEST_LENGTH] = {0};
CCHmac(kCCHmacAlgSHA256,
key,
kCCKeySizeAES128,
[plainData UTF8String],
[plainData lengthOfBytesUsingEncoding: NSUTF8StringEncoding],
hmac);
NSData *hmacData = [NSData dataWithBytes: hmac length: CC_SHA256_DIGEST_LENGTH];
return hmacData;
}
But as soon as I hit ; it marks an error saying "No matching function for call to 'CCKeyDerivationPBKDF'" and it won't build or anything.
I've imported CommonCrypto/CommonKeyDerivation.h and CommonCrypto/CommonCryptor.h as both of these were necessary for the enum names.
First, make sure that you haven't done anything funny with your include path (in particular, I do not recommend #HachiEthan's solution, which just confuses things). In general, leave this alone, and specifically don't add things like /usr/include to it. Make sure you've added Security.framework to your link step. This is the usual cause of problems.
The biggest thing you want to be sure of is that you're getting the iOS 5 Security.framework (rather than some other version like the OS X 10.6 or iOS 4 versions). But my suspicion is that you have a problem with your build settings.
If you want to see a framework that does all of this for reference, take a look at RNCryptor.
Right, I've found the problem (and solution).
Because I was using ZXing I had to rename the .m file to .mm so it could run the C++ stuff in the ZXing library.
I don't know why but renaming the file this way broke the CCKeyDerivationPBKDF function.
I've now moved the crypto code into it's own class and left it as .m and all I need now is to include the two imports as I did in the original post.
I didn't have to include any frameworks or anything.
I'm following the suggestion in the answer here for redirecting NSLog output on an iOS device to a file, which works great. The problem is that it no longer shows up in the console on the device. What I'd really like is a way to tee the stderr stream to both the console and the file. Does anyone have an idea how to do that?
I found an acceptable answer on another thread (NSLog() to both console and file).
The solution provided there is to only redirect to a file if a debugger is not detected, like this:
if (!isatty(STDERR_FILENO))
{
// Redirection code
}
Thanks to Sailesh for that answer.
Once you freopen() the file descriptor, you can read from it and do as you please with the data. Some ideas from this will be useful to you.
You could either write it back out to stdout, or try to write directly to /dev/console. I've never tried to open /dev/console on an iPhone, but I'm guessing it's possible despite being outside of the sandbox. I'm not sure how the app review process will treat it.
Or you can redirect to a TCP socket and view on a remote telnet client. No need for XCode this way!
Basically:
Create a standard C function which calls an Obj-C static method:
void tcpLogg_log(NSString* fmt, ...)
{
va_list args;
va_start(args, fmt);
[TCPLogger tcpLog:fmt :args];
va_end(args);
}
The static Obj-C method:
(void)tcpLog:(NSString*)fmt :(va_list)args
{
NSLogv(fmt, args);
if(sharedSingleton != nil && sharedSingleton.socket != nil)
{
NSString *time = [sharedSingleton.dateFormat stringFromDate:[NSDate date]];
NSString *msg = [[NSString alloc] initWithFormat:fmt arguments:args];
mach_port_t tid = pthread_mach_thread_np(pthread_self());
NSString *str = [NSString stringWithFormat:#"%#[%X]: %#\r\n", time, tid, msg];
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
[sharedSingleton.socket writeData:data
withTimeout:NETWORK_CLIENT_TIMEOUT_PERIOD
tag:0];
}
}
Then in your .pch file, add the following lines to override NSLog()
define NSLog(...) tcpLogg_log(__VA_ARGS__);
void tcpLogg_log(NSString* fmt, ...);
Of course more details are required to handle the TCP Socket. Working source code is available here:

Everything I see about iPhone localization is, unsurprisingly, in Objective-C. The project I'm working on is already written and working on iPhone using almost entirely C++, and we have a few complete translations already. All we need now, is a way to find out the locale/language code. On the computer, this is done using getenv, checking "LANG", or if that's not set "LC_ALL". This doesn't seem to work on the iPhone (neither is set to anything), so I need some other method.
As far as I can tell, the best way to do it with Objective-C is:
NSString* languageCode = [[NSLocale preferredLanguages] objectAtIndex:0];
But then I'd have to convert from NSString* to char*/std::string (which can be done, but it's generally annoying/messy). So I'm wondering, is there an easier way to get the locale from C++ directly?
Here's what I ended up doing:
#if TARGET_OS_IPHONE || TARGET_IPHONE_SIMULATOR
#include <CoreFoundation/CoreFoundation.h>
#endif
/* ... */
#if TARGET_OS_IPHONE || TARGET_IPHONE_SIMULATOR
CFArrayRef localeIDs = CFLocaleCopyPreferredLanguages();
if (localeIDs)
{
CFStringRef localeID = (CFStringRef)CFArrayGetValueAtIndex(localeIDs, 0);
char tmp[16];
if (CFStringGetCString(localeID, tmp, 16, kCFStringEncodingUTF8))
locale = std::string(tmp); //this is the std::string
CFRelease(localeIDs);
}
#endif
Probably you want to use CFLocaleGetValue()
I want to know the serial number of my iPhone using my application. I have writen code below.
- (NSString*)getSerialNumber
{
CFTypeRef serialNumberAsCFString;
io_service_t platformExpert = IOServiceGetMatchingService(kIOMasterPortDefault, IOServiceMatching("IOPlatformExpertDevice"));
if (platformExpert)
{
serialNumberAsCFString = IORegistryEntryCreateCFProperty(platformExpert, CFSTR(kIOPlatformUUIDKey), kCFAllocatorDefault, 0);
}
IOObjectRelease(platformExpert);
NSString *serial = [[NSString alloc] initWithFormat:#"%#",serialNumberAsCFString];
NSLog(#"serail no==>%#",serialNumberAsCFString);
NSLog(#"serail no==>%#",serial);
}
Why am I still getting wrong serial number?
You should change the argument 2 of IORegistryEntryCreateCFProperty from CFSTR (kIOPlatformUUIDKey) to CFSTR (kIOPlatformSerialNumberKey). Then you will get the correct serial number(with length of 11 characters).
Are you linking the IOKit framework?
Try the
id getValue(NSString *iosearch);
function, available at
http://blogs.oreilly.com/iphone/2008/08/retrieving-device-information.html
You can also use the UIDevice class to retrieve other useful information
For instance, you can do:
NSString *id = [[UIDevice currentDevice] uniqueIdentifier];
Other useful properties are the following ones:
name
systemName
systemVersion
model
localizedModel
Ready to use category on UIDevice: UIDevice+serialNumber. Not sure this would be accepted on the App Store.
