整理：iOS 短信与电话事件的获取

Core Telephony

iOS 4.0 的官方 API 裡頭，多了一個叫做 Core Telephony 的 framework；一直以來 Core Telephony 都是 private API，現在開放出來，但是從文件來看，裡頭根本沒有幾行，既沒有告訴你應該怎麼用，也沒有範例，你從 framework 裡頭寥寥四個 class 的 header 中，也搞不清楚，究竟可以把這個東西用在什麼用途上。

目前只知道可以拿來做兩件事情：1. 知道目前你這隻 iPhone 用的是哪個電信商的服務；2. 知道現在 iPhone 是不是在打電話。

※ 電信商資訊

用 CTTelephonyNetworkInfo 與 CTCarrier 這兩個 class，就可以取得電信商資訊，例如：

CTTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init];

CTCarrier *carrier = info.subscriberCellularProvider;

NSLog(@"carrier:%@", [carrier description]);

倒出來的結果像是：

CTCarrier (0x140dc0) {

	Carrier name: [中華電信]

	Mobile Country Code: [466]

	Mobile Network Code:[92]

	ISO Country Code:[tw]

	Allows VOIP? [YES]

}

然後，如果你對 CTTelephonyNetworkInfo 餵一個 block 進去，像是：

info.subscriberCellularProviderDidUpdateNotifier = ^(CTCarrier *carrier) {NSLog(@"carrier:%@", [carrier description]);};

如此一來，當你的 iPhone 漫遊到了其他網路的時候，就會執行你這段 block，但光是知道手機現在漫遊在哪個電信商的網路裡頭，大概能做的，就是一些跟電信商關係密切的服務之類，你或許可以決定軟體裡頭有哪些功能，一定要在某個電信商的網路才能用；電信商自己做 iPhone 軟體的時候大概會想做這種事情。

※ 通話資料

用 CTCallCenter 與 CTCall 這兩個 class，便可以知道目前 iPhone 是否在通話中。CTCallCenter 的用途是用來監控是不是有電話打進來、正在接聽、或是已經掛斷，而 CTCall 則是將每一則通話事件包裝成一個物件。我們先寫一小段程式－

CTCallCenter *center = [[CTCallCenter alloc] init];

center.callEventHandler = ^(CTCall *call) {

	NSLog(@"call:%@", [call description]);

};

然後，在實機上執行，接著打通電話到這支 iPhone 上，打通電話進去，然後馬上掛斷（人好端端的，幹嘛為了測試程式跟自己的電話費帳單過不去呢？）就可以看到 iPhone 執行了我們的 block，把 CTCall 物件倒出來：

CTCall (0x143400) {

	callState: [CTCallStateIncoming]

	Call ID: [CE5F9337-1990-4254-8797-1CCEA85B061B]

}

CTCall (0x10bac0) {

	callState: [CTCallStateDisconnected]

	Call ID: [CE5F9337-1990-4254-8797-1CCEA85B061B]

}

CTCall 物件只有兩個屬性，一是通話狀態（來電中、通話中…），二是這則通話的 unique id，除此之外沒有其他資訊，你沒辦法知道這通電話是從哪裡打來的，只能知道有電話進來而已，也沒辦法透過這個 API 打電話出去。

大抵上可以想到的用途，就是當你的程式執行到一半的時候，程式流程被電話打斷，這時候就可能要中斷原本正在做的事情，在通話結束之後恢復。

最後，CTCallCenter 與 CTTelephonyNetworkInfo，在模擬器上是沒有辦法用的，呼叫 alloc、init 之後回傳的結果只會是 nil。

/********private api********/

无庸置疑，以下的所有操作必须建立在已越狱的iPhone手机上。

首先，在建立工程之后我们要引入一个名为CoreTelephony.framework的框架，他是一个是一个有关电话、短信和邮件通讯的框架。

注：使用4.x的SDK的开发者可以清楚的看到这个框架中有关电话和运营商的各种类（/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.x.sdk/System/Library/Frameworks/CoreTelephony.framework），而其在3.x的SDK中是一个私有框架（/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.x.sdk/System/Library/PrivateFrameworks/CoreTelephony.framework），我们可以使用class-dump（目前最新版本为3.3.4）去dump去得到那些有关的类。

接着，我们要引入一些没有在文档中出现，但又确实存在的函数，由于我们的实现文件为.mm文件所以引入时最好使用extern "C"方式：

extern "C" CFNotificationCenterRef CTTelephonyCenterGetDefault(void); // 获得 TelephonyCenter (电话消息中心) 的引用
extern "C" void CTTelephonyCenterAddObserver(CFNotificationCenterRef center, const void *observer, CFNotificationCallback callBack, CFStringRef name, const void *object, CFNotificationSuspensionBehavior suspensionBehavior);
extern "C" void CTTelephonyCenterRemoveObserver(CFNotificationCenterRef center, const void *observer, CFStringRef name, const void *object);
extern "C" NSString *CTCallCopyAddress(void *, CTCall *call); //获得来电号码
extern "C" void CTCallDisconnect(CTCall *call); // 挂断电话
extern "C" void CTCallAnswer(CTCall *call); // 接电话
extern "C" void CTCallAddressBlocked(CTCall *call);
extern "C" int CTCallGetStatus(CTCall *call); // 获得电话状态　拨出电话时为３，有呼入电话时为４，挂断电话时为５
extern "C" int CTCallGetGetRowIDOfLastInsert(void); // 获得最近一条电话记录在电话记录数据库中的位置

以上这些方法都在CoreTelephony这个库中实现，这也是为什么我们要一开始就引入这个框架了。

第三步：我们就要是要在SpringBaord启动之后就将我们的回调函数注册到CTTelephonyCenter这个消息中心，注册我们就放在Hook到SpringBoard的applicationDidFinishLaunching:的那个函数中去：

CTTelephonyCenterAddObserver(CTTelephonyCenterGetDefault(), NULL, &callBack, CFSTR("kCTCallStatusChangeNotification"), NULL, CFNotificationSuspensionBehaviorHold);
　　
这里用到的CTTelephonyCenterAddObsever这个函数基本上与文档中给出的CFNotificationCenterAddObserver这个函数一样，所以我们可以参照后者对前者进行使用（经我测试用法基本相同）。

最后，就是对回调函数的实现:

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

　　if ([(NSString *)name isEqualToString:@"kCTCallStatusChangeNotification"]) {

　　　　CTCall *call = (CTCall *)[(NSDictionary *)userInfo objectForKey:@"kCTCall"];

　　　　NSString *caller = CTCallCopyAddress(NULL, call); // caller 便是来电号码

　　　　CTCallDisconnect(call); //　挂断电话

　　　　CTCallAnswer(call); // 接电话

　　　　CTCallGetStatus(CTCall *call); // 获得电话状态　拨出电话时为３，有呼入电话时为４，挂断电话时为５

　　　　CTCallGetGetRowIDOfLastInsert(void); // 获得最近一条电话记录在电话记录数据库（call_history.db)中的位置(ROWID)

　　}

以上代码经测试可以使用：

测试机型：iPhone 3GS

系统版本：iOS 4.3.3

手机状态：已越狱

测试结果：Perfect！

1.私有api获取电话号码

需要CoreTelephony.framework

extern NSString* CTSettingCopyMyPhoneNumber();
+(NSString *) phoneNumber {
NSString *phone = CTSettingCopyMyPhoneNumber();
return phone;
}
