ios – CoreTelephony因原因崩溃：收到没有通知名称的通知

2023年1月28日 209次阅读

我每天收到大约5,000个报告的问题,原因是“收到了没有通知名称的通知”.

Application Specific Information:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException'  reason: 'Received a notification with no notification name'

我发现所有CoreTelephony通知并尝试重现该问题但失败了.

    /* For use with the CoreTelephony notification system. */
    extern CFStringRef kCTRegistrationStatusChangedNotification;
    extern CFStringRef kCTRegistrationStateDurationReportNotification;
    extern CFStringRef kCTRegistrationServiceProviderNameChangedNotification;
    extern CFStringRef kCTRegistrationOperatorNameChangedNotification;

    extern CFStringRef kCTRegistrationCustomerServiceProfileUpdateNotification;
    extern CFStringRef kCTRegistrationCellChangedNotification;
    extern CFStringRef kCTRegistrationCauseCodeNotification;

为什么我会这次崩溃？
我怎样才能更改我的代码,以便我不再遇到这个问题？
任何帮助都非常感谢.

编辑：

我正在使用Reachability类(https://github.com/tonymillion/Reachability)来检测网络类型.

+ (NSString *)networkName
 {    
    Reachability *reach = [Reachability reachabilityForInternetConnection];
    [reach startNotifier];

    NetworkStatus networkStatus = [reach currentReachabilityStatus];
    CTTelephonyNetworkInfo *telephonyInfo = [[CTTelephonyNetworkInfo alloc] init];

    if (networkStatus == ReachableViaWiFi) {
        return @"WIFI";
    } else if (networkStatus == ReachableViaWWAN) {
        if ([telephonyInfo respondsToSelector:@selector(currentRadioAccessTechnology)]) { 
            if ([[telephonyInfo currentRadioAccessTechnology] isEqualToString:CTRadioAccessTechnologyGPRS]) {
                return @"GPRS";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyEdge]) {
                return @"EDGE";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyWCDMA]) {
                return @"WCDMA";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyHSDPA]) {
                return @"HSDPA";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyHSUPA]) {
                return @"HSUPA";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyCDMA1x]) {
                return @"CDMA1X";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyCDMAEVDORev0]) {
                return @"CDMAEVDOREV0";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyCDMAEVDORevA]) {
                return @"CDMAEVDOREVA";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyCDMAEVDORevB]) {
                return @"CDMAEVDOREVB";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyeHRPD]) {
                return @"HRPD";
            } else if ([[telephonyInfo currentRadioAccessTechnology]  isEqualToString:CTRadioAccessTechnologyLTE]) {
                return @"LTE";
            }
            return @"UNKNOWN";
        } else {
            return @"WWAN";
        }
    } else {
        return @"NotReachable";
    }
}

最佳答案 我想知道这是否与旧版TestFlight的
this similar issue有关：

There is an iOS bug that causes instances of the CTTelephonyNetworkInfo class to sometimes get notifications after they have been deallocated. Instead of instantiating, using, and releasing instances you must instead retain and never release them to work around the bug.

从你的回溯看起来就像一个僵尸.为什么不尝试使用CTTelephonyNetworkInfo的静态实例,这个实例从未按链接问题的建议发布？

@import CoreTelephony;

// ...

static CTTelephonyNetworkInfo *netInfo;
static dispatch_once_t dispatchToken;
if (!netInfo) {
    dispatch_once(&dispatchToken, ^{
        netInfo = [[CTTelephonyNetworkInfo alloc] init];
    });
}
