iOS开发中的权限

权限分类

  • 联网权限

  • 相册权限

  • 相机、麦克风权限

  • 定位权限

  • 推送权限

  • 通讯录权限

  • 日历、备忘录权限

  //获取联网状态
  switch (state) {
      case kCTCellularDataRestricted:
          NSLog(@"Restricrted");
          break;

定位权限

导入头文件@import CoreLocation;

由于iOS8.0之后定位方法的改变，需要在info.plist中进行配置；

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

最后一点

素有获取权限的方法，多用于用户第一次操作应用，iOS 8.0之后，将这些设置都整合在一起，并且可以开启或关闭相应的权限。所有的权限都可以通过下面的方法打开：
