1.联网权限
引入头文件@import CoreTelephony
应用启动后，检测应用中是否有联网权限

CTCellularData * cellularData = [[CTCellularData alloc] init];
cellularData.cellularDataRestrictionDidUpdateNotifier =  ^(CTCellularDataRestrictedState state){
  //获取联网状态
  switch (state) {
      case kCTCellularDataRestricted:
          NSLog(@"Restricrted");
          break;
      case kCTCellularDataNotRestricted:
          NSLog(@"Not Restricted");
          break;
      case kCTCellularDataRestrictedStateUnknown:
          NSLog(@"Unknown");
          break;
      default:
          break;
  };
};

查询应用是否有联网功能

CTCellularData *cellularData = [[CTCellularData alloc]init];
CTCellularDataRestrictedState state = cellularData.restrictedState;
 switch (state) {
  case kCTCellularDataRestricted:
      NSLog(@"Restricrted");
      break;
  case kCTCellularDataNotRestricted:
      NSLog(@"Not Restricted");

      NSLog(@"Authorized");
  }else{
      NSLog(@"Denied or Restricted");
  }
  }];

3.相机和麦克风权限
导入头文件@import AVFoundation；

获取定位权限

CLLocationManager *manager = [[CLLocationManager alloc] init];
[manager requestAlwaysAuthorization];//一直获取定位信息
[manager requestWhenInUseAuthorization];//使用的时候获取定位信息

在代理方法中查看权限是否改变

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{
 switch (status) {
  case kCLAuthorizationStatusAuthorizedAlways:
      NSLog(@"Always Authorized");
      break;

           NSLog(@"Authorized");
        }else{
 
           NSLog(@"Denied or Restricted");
        }
    }];

7、日历、备忘录权限
检查是否有日历或者备忘录权限
