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

联网权限

• 引入头文件 @import CoreTelephoney
• 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 kCellularDataRestricted;
      break;  //Retricrted
      case kCTCellularDataNotRestricted;
      break;  //Not Restricted
      case kCTCellularDataRestrictedStateUnknown;
      break;  //Unknow
    default;
    break;
   }
}

• 查询应用是否有联网功能

CTCellularData *cellularData = [CTCellularData alloc]init];
CTCellularDataRestrictedState state = cellularDate.restrictedState;
switch(state){
    case kCTCellularDataRestriccted; //Restricrted
    break;
    case kCTCekkularDateNotResrricted ; //Not Restricted
    break;
    case cCTCellularDataRestrictedStateUnknow;  //Unknow
    break;
  default;
break;
}

相册权限 （ios9.0 之前）

• 导入头文件 @import AssetsLibrary;
• 检测是否有相册权限

ALAuthorizationStatus status = [ALAssetsLibrary authorizationStatus];
 switch(state)
  case ALAuthorizationStatusAuthorized //Authorized;
  break
  case ALAuthorizationStatusNotDetermined; //DEnied
  break
  case ALAuthorizationStatusNotDetermined; //Determined
  break
  case ALAuthorizationStatusTestricted;
  break;
default
break
}

相机和麦克风权限

• 导入头文件 @import AVFoundation;
• 检查是否有相机或麦克风权限

AVAuthorizationStatus AVstatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];//相机权限
AVAuthorizationStatus AVstatus = [AVCaotureDevice authorizationStatusForMediaType:AVMediaTypeAudio];//麦克风权限
  switch(ACstatus){
  case AVAuthorizationStatusAuthorized; //Authorized
  break
  case AVAuthorizationStatusDenied; //Denied
  break
  case AVAuthorizationStatusNotDetermined
  break
  case AVAuthorizationStatusTrstricted; //Restricted
  break
datault 
  break
}

定位权限

• 导入头文件 @import CoreLocation;
• 由于iOS80之后定位方法的改变 需要在info.plost 中进行配置

  NSLocationWhenUseUsageDescription String  在使用时获取定位信息
  NSLocationAlwaysUsageDescription    String 一直获取定位信息

• 检查是否有定位权限

 BOOL isLocation = [CLLocationManager locationServicesEnabled];
  if(!isLocation){ // not turn on the loaction
}
CLAuthorizationStatus CLstatus = [CLLocationManager authorizationStatus];
  switch(CLstatus){
        case kClAuthorizationStatusAuthorizedALways;  //always Authorized
        break;
        case kClAuthorizationStatusAuthorizedWhenInUse; //AuthotizationStatusAuthorizedWhenInUse
      break;
.......
default
break
}       

• 获取定位权限

CLLocation *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

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。所有的权限都可以同下面的方法打开；

[[UIApplication sharedApplication]openURL URLWithString:UIApplicationOpenSettingsURLString]];
