iOS開發之iOS13推送deviceToken處理

iOS13新出之后會有收不到推送的問題

因為iOS13的處理方法變了，代碼如下

//獲取DeviceToken成功
- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    //Xcode11打的包，iOS13獲取Token有變化
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 13) {
        if (![deviceToken isKindOfClass:[NSData class]]) {
            //記錄獲取token失敗的描述
            return;
        }
        const unsigned *tokenBytes = (const unsigned *)[deviceToken bytes];
        NSString *strToken = [NSString stringWithFormat:@"%08x%08x%08x%08x%08x%08x%08x%08x",
                              ntohl(tokenBytes[0]), ntohl(tokenBytes[1]), ntohl(tokenBytes[2]),
                              ntohl(tokenBytes[3]), ntohl(tokenBytes[4]), ntohl(tokenBytes[5]),
                              ntohl(tokenBytes[6]), ntohl(tokenBytes[7])];
        NSLog(@"deviceToken1:%@", strToken);
        return;
    } else {
        NSString *token = [NSString
                       stringWithFormat:@"%@",deviceToken];
        token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
        token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
        token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
        NSLog(@"deviceToken2 is: %@", token);
    }
}
