Generating pgpkey from ObjectivePGP libaray libaray

Tried with both the types but not able to get pgpKey

1)I have used the above publickKeyData in below code but it returns nil in NSArray of keys

   NSData* publickKeyData = [publickKey 
   dataUsingEncoding:NSUTF8StringEncoding];

   NSArray<PGPKey *> *keys = [ObjectivePGP readKeysFromData:publickKeyData];

2)I have used the above publickKeyData in below code but it returns nil in PGPPacket

  NSUInteger offset = 0; 
  NSUInteger nextPacketOffset = 0;

  PGPPacket * pgpPacket =   [PGPPacketFactory packetWithData:publickKeyData offset:offset nextPacketOffset:&nextPacketOffset];

 NSArray<PGPPacket*> * array = @[pgpPacket];

 PGPPartialKey *pgpPartialKey = [[PGPPartialKey alloc] initWithPackets:array ];

  PGPKey *pgpKey =   [[PGPKey alloc] initWithSecretKey:nil publicKey:pgpPartialKey];

 NSArray<PGPKey *> * pgpKeys =  @[pgpKey];

i have tried with both types but not able to get the PGPKey from ObjectivePGP libaray, i'm doing wrong this above key works in android with bouncycastle pgp but not in ObjectivePGP

How to solve this problem ?

Any help would be appreciated!
