iOS 12之前：

id info = nil;
    NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();
    for (NSString *ifnam in ifs) {
        info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
        NSString *str = info[@"SSID"];//name
        
    }

iOS 12之后以上方法獲取不到，需要在Xcode中TARGET-->Capabilities打開Access WiFi Information選項

iOS 13之后以上方法獲取Wi-Fi名返回的都是固定值"WLAN"，這里可能是因為蘋果保護用戶隱私而產(chǎn)生的問題，因為通過wifi信息可以定位到用戶地理位置。所以iOS13以后如果想要繼續(xù)獲取WiFi名稱，需要在調(diào)用接口前判斷用戶是否同意App使用地理位置信息?？梢栽诔绦蛞粏訒r請求用戶權(quán)限，調(diào)用的方法如下：

#import <CoreLocation/CoreLocation.h>

@property (strong, nonatomic) CLLocationManager *locationManager;

NSString* phoneVersion = [[UIDevice currentDevice] systemVersion];
CGFloat version = [phoneVersion floatValue];
// 如果是iOS13 未開啟地理位置權(quán)限 需要提示一下
if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined && version >= 13) {
    self.locationManager = [[CLLocationManager alloc] init];
    [self.locationManager requestWhenInUseAuthorization];
}

如果用戶拒絕了授權(quán)，在需要獲取Wi-Fi名的界面加上提示：

    NSString* phoneVersion = [[UIDevice currentDevice] systemVersion];
    CGFloat version = [phoneVersion floatValue];
    //如果開啟地理位置權(quán)限未開啟 需要提示一下
    if (([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusRestricted || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied  )&& version >= 13) {
        [PracticalTools showAlertViewWithTitle:@"提示" message:@"您的位置權(quán)限尚未授權(quán)，將無法獲取當前Wi-Fi進行配置網(wǎng)絡(luò)，請前往“設(shè)置”-“Photoegg”-“位置”進行授權(quán)！" doneText:@"確定" cancelText:nil doneHandle:nil cancelHandle:nil vc:self];
