iOS来电显示检索 [英] iOS Caller ID Retrieve

问题描述

我试图用下面的代码获取调用者号码（用于越狱设备）：
extern CFTypeRef CTCallCopyName（void *，CTCall * call）;

< （CTCallCopyName（NULL，（CTCall *）call））;

我收到错误：
CTCallCopyName（void *，CTCall *），引用自：
ld：符号（s）未找到架构armv6

我的Core Telephony与我的项目链接。
也许我的原型是错的......我不知道。有任何想法吗？
Xcode 3，sdk 4

解决方案

如果您在.mm文件中调用此API，则必须声明它像extern C void foo（void）;据我所知，在iOS 5〜7上，应该使用CTCallCopyAddress，原型是：

  externC CFStringRef CTCallCopyAddress（CFAllocatorRef，CTCallRef）; 
  

注意，第二个参数是 CTCallRef ，而不是 CTCall ，这意味着你不能发送它CTCall类的方法（尽管其中一些工作）。除了链接CoreTelephony.framework，您还可以动态加载此符号，如下所示：

  static CFStringRef（* CTCallCopyAddress）（CFAllocatorRef ，CTCallRef）; 
 
 void Foo（CTCallRef调用）
 {
 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（@调用者的地址是％@，地址）; 
 [地址发布]; 
 dlclose（libHandle）; 
} 
  

顺便说一下，我无法让CTCallCopyName在iOS 5的SpringBoard上工作，还没有弄清楚或试用过其他系统。希望这些信息对您有所帮助！编辑：在iOS 5上再次尝试一下，CTCallGetID是在地址簿中获取调用者ID的正确函数，其原型是ABRecordID CTCallGetID （CTCallRef）。 iOS 6和7可能是相同的。

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

解决方案

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.
