How to solve the problem that iOS13 can't get WiFi name
This article will explain in detail how to solve the problem that iOS13 can not get WiFi names. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
After upgrading to iOS13, it is found that the interface that previously obtained the WiFi name has failed, and the fixed value "WLAN" is returned. This may be because Apple protects the privacy of users, because the user's geographic location can be located through wifi information. Therefore, if iOS13 wants to continue to obtain the WiFi name in the future, you need to determine whether the user agrees to use the geographic location information of app before calling the API.
I will only use the hint here for the first time:
NSString* phoneVersion = [[UIDevice currentDevice] systemVersion]; CGFloat version = [phoneVersion floatValue]; / / if iOS13 does not have geolocation permission enabled, you need to prompt if ([CLLocationManager authorizationStatus] = = kCLAuthorizationStatusNotDetermined & & version > = 13) {self.locationManager = [[CLLocationManager alloc] init]; [self.locationManager requestWhenInUseAuthorization];}
Knowledge point expansion:
IOS gets the current Wifi name
1. Project header file import
# import
two。 Implement the following code to return the network name of the current connection
-(NSString *) currentWifiSSID {NSString * ssid = nil; NSArray * ifs = (_ _ bridge id) CNCopySupportedInterfaces (); for (NSString * ifname in ifs) {NSDictionary * info = (_ _ bridge id) CNCopyCurrentNetworkInfo ((_ _ bridge CFStringRef) ifname); if (info [@ "SSIDD"]) {ssid = info [@ "SSID"];}} return ssid;}
