ios开发获取SIM卡信息

.加入一个Framework(CoreTelephony.framework)..引入头文件#import<CoreTelephony/CoreTelephonyDefines.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 ://供应商名称（中国联通 中国移动）            cell.textLabel.text = @"carrierName";            cell.detailTextLabel.text = carrier.carrierName;            break;        case ://所在国家编号            cell.textLabel.text = @"mobileCountryCode";            cell.detailTextLabel.text = carrier.mobileCountryCode;            break;        case ://供应商网络编号            cell.textLabel.text = @"mobileNetworkCode";            cell.detailTextLabel.text = carrier.mobileNetworkCode;            break;        case :            cell.textLabel.text = @"isoCountryCode";            cell.detailTextLabel.text = carrier.isoCountryCode;            break;        case ://是否允许voip            cell.textLabel.text = @"allowsVOIP";            cell.detailTextLabel.text = carrier.allowsVOIP?@"YES":@"NO";            break;        default:            break;    }    return cell;}
