iOS开发中，有时需要检测设备运营商类型，如移动、联通或者电信，本文以检测联通为例。
系统代码

- (BOOL)checkIsUnicom { CTTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init]; CTCarrier *carrier = info.subscriberCellularProvider; NSString *carrierName = carrier.carrierName; NSString *mobileCountryCode = carrier.mobileCountryCode; NSString *mobileNetworkCode = carrier.mobileNetworkCode; [info release]; if (!mobileNetworkCode) { return NO; } if ([mobileCountryCode intValue]==460) { //国内 return [carrierName rangeOfString:@"联通"].length>0 || [mobileNetworkCode isEqualToString:@"01"] || [mobileNetworkCode isEqualToString:@"06"]; } return [self statusBarCheckIsUnicom]; } |
运行商对应的NetworkCode
正常情况下，以上代码可满足正常需求，但是对于美版或者日版卡贴iPhone，检测到的CTCarrier并非sim卡信息，此时就需要通过StatusBar实时检测当前网络运行商

- (BOOL)statusBarCheckIsUnicom { NSArray *subviews = [[[[UIApplication sharedApplication] valueForKey:@"statusBar"] valueForKey:@"foregroundView"] subviews]; UIView *serviceView = nil; Class serviceClass = NSClassFromString([NSString stringWithFormat:@"UIStat%@Serv%@%@", @"usBar", @"ice", @"ItemView"]); for (UIView *subview in subviews) { if([subview isKindOfClass:[serviceClass class]]) { serviceView = subview; break; } } if (serviceView) { NSString *carrierName = [serviceView valueForKey:[@"service" stringByAppendingString:@"String"]]; return [carrierName rangeOfString:@"联通"].length>0; } else { return NO; } } |
