ios获取sim卡信息以及手机号码

 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>

@interface RootViewController : UITableViewController

{

    //声明变量

    CTTelephonyNetworkInfo *networkInfo;

}

@end

@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
