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 0:  
                NSLog(@"No wifi or cellular");  
                infoLabel.text=@"无服务";  
                break;  
                  
            case 1:  
                NSLog(@"2G");  
                infoLabel.text=@"2G";  
                break;  
                  
            case 2:  
                NSLog(@"3G");  
                infoLabel.text=@"3G";  
                break;  
                  
            case 3:  
                NSLog(@"4G");  
                infoLabel.text=@"4G";  
                break;  
                  
            case 4:  
                NSLog(@"LTE");  
                infoLabel.text=@"LTE";  
                break;  
                  
            case 5:  
                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:@"460"]) {
        return YES;
    }else{
        return NO;
    }
    
}
