這裡的實現原理是獲取到來電系統通知,然後根據本地通話的電話號碼,把對應電話的聯系人.

情況一 來電號碼未在通訊錄聯系人中, 這時候要先在通訊錄添加一個臨時的聯系人(就是新建一個聯系人,並保存對應的RecordID)

情況二 已在通訊錄的聯系人

然後 把對應本次通話的電話標簽修改成歸屬地字符

 

 

好了 ,先看看怎麼獲取系統電話通知

需要的類

 

//創建電話對象

代碼一:

 

#import

@import CoreTelephony;

 

// private API

typedef NS_ENUM(short, CTCallStatus) {

kCTCallStatusConnected = 1, //已接通

kCTCallStatusCallOut = 3, //撥出去

kCTCallStatusCallIn = 4, //打進來

kCTCallStatusHungUp = 5 //掛斷

};

 

@interface WCCall : NSObject

 

@property (nonatomic,assign) CTCallStatus callStatus;

@property (nonatomic,copy) NSString *phoneNumber;

@property (nonatomic,retain) CTCall *internalCall;

 

@end

代碼二:

#import WCCall.h

 

@implementation WCCall

 

@end

 

//監聽電話通知

代碼三:

 

#import

#import WCCall.h

 

@interface WCCallCenter : NSObject

 

// 監聽來電事件

@property (nonatomic,strong) void (^callEventHandler)(WCCall *call);

 

// 掛斷電話

- (void)disconnectCall:(WCCall *)call;

 

@end

 

代碼四:

 

#import WCCallCenter.h

#import WCUtil.h

 

// encrypted string's

#define ENCSTR_kCTCallStatusChangeNotification [@n0AHD2SfoSA0LKE1p0AbLJ5aMH5iqTyznJAuqTyiot== wcDecryptString]

#define ENCSTR_kCTCall [@n0AHD2SfoN== wcDecryptString]

#define ENCSTR_kCTCallStatus [@n0AHD2SfoSA0LKE1pj== wcDecryptString]

#define ENCSTR_CTTelephonyCenterGetDefault [@D1EHMJkypTuioayQMJ50MKWUMKERMJMuqJk0 wcDecryptString]

#define ENCSTR_CTTelephonyCenterAddObserver [@D1EHMJkypTuioayQMJ50MKWOMTECLaAypaMypt== wcDecryptString]

#define ENCSTR_CTTelephonyCenterRemoveObserver [@D1EHMJkypTuioayQMJ50MKWFMJ1iqzICLaAypaMypt== wcDecryptString]

#define ENCSTR_CTCallCopyAddress [@D1EQLJkfD29jrHSxMUWyp3Z= wcDecryptString]

#define ENCSTR_CTCallDisconnect [@D1EQLJkfETymL29hozIwqN== wcDecryptString]

 

//這裡需要對字符串 NSString 進行拓展方法

//#import 引用 這個框架

程序啟動的情況下 來電/去電/接通/掛斷 都可以獲到了, 文章到此結束了, 敬請期待 對聯系人添加歸屬地, 修改聯系人操作博客.....
