iOS获取运营商的相关信息

1.导入：CoreTelephony.framework

2.添加头文件

#import <CoreTelephony/CTTelephonyNetworkInfo.h>
#import <CoreTelephony/CTCarrier.h>  

3.获取网络环境

    -(void)networktype{
        NSArray *subviews = [[[[UIApplication sharedApplication] valueForKey:@"statusBar"] valueForKey:@"foregroundView"]subviews];
        NSNumber *dataNetworkItemView = nil;  

        for (id subview in subviews) {
            if([subview isKindOfClass:[NSClassFromString(@"UIStatusBarDataNetworkItemView") class]]) {
                dataNetworkItemView = subview;
                break;
            }
        }  

        switch ([[dataNetworkItemView valueForKey:@"dataNetworkType"]integerValue]) {
            case :
                NSLog(@"No wifi or cellular");
                infoLabel.text=@"无服务";
                break;  

            case :
                NSLog(@"2G");
                infoLabel.text=@"2G";
                break;  

            case :
                NSLog(@"3G");
                infoLabel.text=@"3G";
                break;  

            case :
                NSLog(@"4G");
                infoLabel.text=@"4G";
                break;  

            case :
                NSLog(@"LTE");
                infoLabel.text=@"LTE";
                break;  

            case :
                NSLog(@"Wifi");
                infoLabel.text=@"Wifi";
                break;  

            default:
                break;
        }}  

4.获取运营商信息

+ (BOOL)isInChina{

    CTTelephonyNetworkInfo *telephonyInfo = [[CTTelephonyNetworkInfo alloc] init];
    CTCarrier *carrier = [telephonyInfo subscriberCellularProvider];
    //NSString *currentCountry = [carrier carrierName];
    NSLog(@"[carrier carrierName]==%@,[carrier mobileCountryCode]==%@,[carrier mobileNetworkCode]==%@,[carrier isoCountryCode]==%@,[carrier allowsVOIP]==%d",[carrier carrierName],[carrier mobileCountryCode],[carrier mobileNetworkCode],[carrier isoCountryCode],[carrier allowsVOIP]);

    if ([[carrier mobileCountryCode] isEqualToString:@""]) {
        return YES;
    }else{
        return NO;
    }

}
