1.联网权限

1. 引入头文件 @import CoreTelephony;
2. 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;
  };
};

3. 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");      
         break;  
   case kCTCellularDataRestrictedStateUnknown:
         NSLog(@"Unknown");      
         break;
   default:
         break;
}

2.相册权限--iOS 9.0之前

1. 导入头文件@import AssetsLibrary;
2. 检查是否有相册权限

PHAuthorizationStatus photoAuthorStatus = [PHPhotoLibrary authorizationStatus];
switch (photoAuthorStatus) {
  case PHAuthorizationStatusAuthorized:
        NSLog(@"Authorized");      
        break;
  case PHAuthorizationStatusDenied:
        NSLog(@"Denied");      
        break;
  case PHAuthorizationStatusNotDetermined:
        NSLog(@"not Determined");      
        break;  
  case PHAuthorizationStatusRestricted:
        NSLog(@"Restricted");      
        break;  
  default:      
        break;
}

3. 获取权限

[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
  if (status == PHAuthorizationStatusAuthorized) {
        NSLog(@"Authorized");
  }else{
        NSLog(@"Denied or Restricted");
  }
  }];

3.相机和麦克风权限

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

AVAuthorizationStatus AVstatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];//相机权限
AVAuthorizationStatus AVstatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];//麦克风权限
switch (AVstatus) {
  case AVAuthorizationStatusAuthorized:
        NSLog(@"Authorized");      
        break;  
  case AVAuthorizationStatusDenied:
        NSLog(@"Denied");      
        break;  
  case AVAuthorizationStatusNotDetermined:
        NSLog(@"not Determined");      
        break; 
  case AVAuthorizationStatusRestricted:
        NSLog(@"Restricted");      
        break;  
  default:      
        break;
}

3. 获取相机或麦克风权限

[AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {//相机权限
  if (granted) {
      NSLog(@"Authorized");
  }else{
      NSLog(@"Denied or Restricted");
  }
}];
[AVCaptureDevice requestAccessForMediaType:AVMediaTypeAudio completionHandler:^(BOOL granted) {//麦克风权限
  if (granted) {
      NSLog(@"Authorized");
  }else{
      NSLog(@"Denied or Restricted");
  }
}];

4.定位权限

1. 导入头文件@import CoreLocation;
2. 由于iOS8.0之后定位方法的改变，需要在info.plist中进行配置；
3. 检查是否有定位权限

BOOL isLocation = [CLLocationManager locationServicesEnabled];
if (!isLocation) {
  NSLog(@"not turn on the location");}
CLAuthorizationStatus CLstatus = [CLLocationManager authorizationStatus];
switch (CLstatus) {
  case kCLAuthorizationStatusAuthorizedAlways:
        NSLog(@"Always Authorized");      
        break;
  case kCLAuthorizationStatusAuthorizedWhenInUse:
        NSLog(@"AuthorizedWhenInUse");      
        break;
  case kCLAuthorizationStatusDenied:
        NSLog(@"Denied");      
        break;  
  case kCLAuthorizationStatusNotDetermined:
        NSLog(@"not Determined");      
        break;  
  case kCLAuthorizationStatusRestricted:
        NSLog(@"Restricted");      
        break;  
  default:      
        break;
}

4. 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

5.推送权限

1. 检查是否有通讯权限

UIUserNotificationSettings *settings = [[UIApplication sharedApplication] currentUserNotificationSettings];switch (settings.types) {
  case UIUserNotificationTypeNone:
        NSLog(@"None");      
        break;  
  case UIUserNotificationTypeAlert:
        NSLog(@"Alert Notification");      
        break; 
  case UIUserNotificationTypeBadge:
        NSLog(@"Badge Notification");      
        break;  
  case UIUserNotificationTypeSound:
        NSLog(@"sound Notification'");      
        break;  
  default:      
        break;
}

2. 获取推送权限

UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:setting];

6.通讯录权限

1. 导入头文件 @import AddressBook;
2. 检查是否有通讯录权限

 ABAuthorizationStatus ABstatus = ABAddressBookGetAuthorizationStatus();switch (ABstatus) {
   case kABAuthorizationStatusAuthorized:      
         NSLog(@"Authorized");      
         break;  
   case kABAuthorizationStatusDenied:
         NSLog(@"Denied'");      
         break;  
   case kABAuthorizationStatusNotDetermined:
         NSLog(@"not Determined");      
         break;  
   case kABAuthorizationStatusRestricted:
         NSLog(@"Restricted");      
         break;  
   default:      
         break;
}

3. 获取通讯录权限

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
  if (granted) {
        NSLog(@"Authorized");
        CFRelease(addressBook);
  }else{
        NSLog(@"Denied or Restricted");
  }
});

7.日历、备忘录权限

1. 检查是否有日历或者备忘录权限

typedef NS_ENUM(NSUInteger, EKEntityType) {
  EKEntityTypeEvent,//日历
  EKEntityTypeReminder //备忘
 };
EKAuthorizationStatus EKstatus = [EKEventStore  authorizationStatusForEntityType:EKEntityTypeEvent];switch (EKstatus) {
  case EKAuthorizationStatusAuthorized:
        NSLog(@"Authorized");      
        break;  
  case EKAuthorizationStatusDenied:
        NSLog(@"Denied'");      
        break;  
  case EKAuthorizationStatusNotDetermined:
        NSLog(@"not Determined");      
        break;  
  case EKAuthorizationStatusRestricted:
        NSLog(@"Restricted");      
        break; 
  default:
        break;
}

2. 获取日历或备忘录权限

EKEventStore *store = [[EKEventStore alloc]init];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError * _Nullable error) {
  if (granted) {
        NSLog(@"Authorized");
  }else{
        NSLog(@"Denied or Restricted");
  }
}];
