ios - 在iOS 8.3中获取CellID，MCC，MNC，LAC，信号强度，质量和网络

Question

如何使用ios 8.3中的专用api获取单元ID，因为以前的核心电话专用api在最新的ios sdk 8.3中不起作用。

Answer 1

您仍然可以使用它。它适用于iOS 8.3。我不知道如何获得信号强度。苹果最近改变了Core Telephony的许多功能。 :(

CTTelephonyNetworkInfo *telephonyInfo = [CTTelephonyNetworkInfo new];
NSString *carrierNetwork = telephonyInfo.currentRadioAccessTechnology;
NSLog(@"Mobile Network): %@", carrierNetwork);

CTCarrier *carrier = [telephonyInfo subscriberCellularProvider];

NSString *mobileCountryCode = [carrier mobileCountryCode];
NSLog(@"Mobile Country Code (MCC): %@", mobileCountryCode);

NSString *mobileNetworkCode = [carrier mobileNetworkCode];
NSLog(@"Mobile Network Code (MNC): %@", mobileNetworkCode);

NSString *carrierName = [carrier carrierName];
NSLog(@"Mobile Network name: %@", carrierName);

NSString *isoCountryCode = [carrier isoCountryCode];
NSLog(@"Mobile Network isoCode: %@", isoCountryCode);

编辑:我找到了解决方案如何获得信号强度。
*!请注意，以下解决方案使用 private API，因此当提交给App Store时，Apple将拒绝该解决方案。

UIApplication *app = [UIApplication sharedApplication];
NSArray *subviews = [[[app valueForKey:@"statusBar"] valueForKey:@"foregroundView"] subviews];
NSString *dataNetworkItemView = nil;

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

int signalStrength = [[dataNetworkItemView valueForKey:@"signalStrengthRaw"] intValue];

NSLog(@"signal %d", signalStrength);
