1.加入一个Framework(CoreTelephony.framework). 2.引入头文件 #import <CoreTelephony/CTTelephonyNetworkInfo.h> #import <CoreTelephony/CTCarrier.h> 3.初始化 # import <UIKit/UIKit.h> # import <CoreTelephony/CTTelephonyNetworkInfo.h> # import <CoreTelephony/CTCarrier.h> RootViewController : UITableViewController { //声明变量 CTTelephonyNetworkInfo *networkInfo; } @implementation RootViewController - ( void )viewDidLoad { [ super viewDidLoad]; self.navigationItem.prompt = @ "CTTelephonyNetworkInfo" ; self.navigationItem.title = @ "CTCarrier" ; //初始化 networkInfo = [[CTTelephonyNetworkInfo alloc] init]; //当sim卡更换时弹出此窗口 networkInfo.subscriberCellularProviderDidUpdateNotifier = ^(CTCarrier *carrier){ UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@ "Sim card changed" delegate:nil cancelButtonTitle:@ "Dismiss" otherButtonTitles:nil]; [alert show]; }; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { //获取sim卡信息 CTCarrier *carrier = networkInfo.subscriberCellularProvider; static NSString *CellIdentifier = @ "Cell" ; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; } switch (indexPath.row) { case 0 : //供应商名称（中国联通 中国移动） cell.textLabel.text = @ "carrierName" ; cell.detailTextLabel.text = carrier.carrierName; break ; case 1 : //所在国家编号 cell.textLabel.text = @ "mobileCountryCode" ; cell.detailTextLabel.text = carrier.mobileCountryCode; break ; case 2 : //供应商网络编号 cell.textLabel.text = @ "mobileNetworkCode" ; cell.detailTextLabel.text = carrier.mobileNetworkCode; break ; case 3 : cell.textLabel.text = @ "isoCountryCode" ; cell.detailTextLabel.text = carrier.isoCountryCode; break ; case 4 : //是否允许voip cell.textLabel.text = @ "allowsVOIP" ; cell.detailTextLabel.text = carrier.allowsVOIP?@ "YES" :@ "NO" ; break ; default : break ; } return cell; } 获取手机号码
1.NSString *number = [[NSUserDefaults standardUserDefaults] stringForKey:@"SBFormattedPhoneNumber"]; 只能获取的是机主设置的本机号码，不能读取sim卡上的电话号码
2. CTSettingCopyMyPhoneNumber(); 毕竟私有API
