iOS - 适配 iOS 13 之工兵连扫雷

直接上代码// 当定位授权状态改变时

_- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
switch (status)
{
case kCLAuthorizationStatusDenied: // 拒绝授权
NSLog(@"授权失败：用户拒绝授权或未开启定位服务");
break;
case kCLAuthorizationStatusAuthorizedWhenInUse: // 在使用期间使用定位
NSLog(@"授权成功：用户允许应用“使用期间”使用定位服务");
if (geteventID >= 0) {
NSDictionary *ret = @{@"returnVal":[self currentWifiSSID]};
[self sendResultEventWithCallbackId:geteventID dataDict:ret errDict:nil doDelete:YES];
}
break;
}
}
//获取wifi名称

• ( NSString*)currentWifiSSID
  {
  NSArray *interfaceNames = CFBridgingRelease(CNCopySupportedInterfaces());
  NSDictionary *SSIDInfo;
  for (NSString *interfaceName in interfaceNames) {
  SSIDInfo = CFBridgingRelease(CNCopyCurrentNetworkInfo((__bridge CFStringRef)interfaceName));
  BOOL isNotEmpty = (SSIDInfo.count > 0);
  if (isNotEmpty) {
  break;
  }
  }
  NSString * ssid = @"";
  if (![[SSIDInfo objectForKey:@"SSID"] isEqual:@""]&&[SSIDInfo objectForKey:@"SSID"]!=nil) {
  ssid = [SSIDInfo objectForKey:@"SSID"]; //包含信息SSIDInfo_

  }

  return ssid;

}

• (void)get:(NSDictionary *)paramsDict_

{
[setHostComputer launch];
if (_locationManager == nil) {
_locationManager = [CLLocationManager new];
}
geteventID = [paramsDict_ integerValueForKey:@"cbId" defaultValue:-1];
if (_locationManager != nil) {
// 请求“使用期间”使用定位服务
if (@available(iOS 13, *)) {
if (CLLocationManager.authorizationStatus == kCLAuthorizationStatusAuthorizedWhenInUse) {//开启了权限，直接搜索
if (geteventID >= 0) {
NSDictionary *ret = @{@"returnVal":[self currentWifiSSID]};
[self sendResultEventWithCallbackId:geteventID dataDict:ret errDict:nil doDelete:YES];
}

            } else if (CLLocationManager.authorizationStatus == kCLAuthorizationStatusDenied) {//如果用户没给权限，则提示  
                \[UIAlertController alertControllerWithTitle:@"定位权限关闭提示" message:@"你关闭了定位权限，导致无法使用WIFI功能" preferredStyle:UIAlertControllerStyleAlert\];  
            } else {//请求权限  
                \_locationManager.delegate = self;  
                \[\_locationManager requestWhenInUseAuthorization\];  
            }  
        } else {  
                if (geteventID >= 0) {  
                   NSDictionary \*ret = @{@"returnVal":\[self currentWifiSSID\]};  
                   \[self sendResultEventWithCallbackId:geteventID dataDict:ret errDict:nil doDelete:YES\];  
               }

        }

}
