Hi
I m IOS developer and I m working on bitcoin wallet.
for Private key generate I am using core bitcoin lib, and I successfully generate that key
here is code to generate key

Code:

  NSUInteger length = 32;
    NSMutableData *secret = [NSMutableData dataWithLength:length];
    OSStatus sanityCheck = noErr;

    sanityCheck = SecRandomCopyBytes(kSecRandomDefault, length, secret.mutableBytes);
    if (sanityCheck != noErr) {
        NSLog(@"Issue generating a private key.");
    }
    
    NSAssert(secret.length == 32, @"secret must be 32 bytes long");
    BTCKey *key = [[BTCKey alloc] initWithPrivateKey:secret];
    
    NSLog(@"%@",key.WIF);

now I need to use that private key using JSONrpc command importprivkey
here is code to import private key is

Code:

 {
	"jsonrpc":"2.0",
    "params":{
    	"privkey":"5K1PvchJcWx1fay7PQ2DGGXoZLDfZw7htVdbFrEjjDVS8MCag8h",
    	 "rescan":true
    	},
     "method":"importprivkey"
 }

but after run that command I got error of

Code:

{
    "result": null,
    "error": {
        "code": -5,
        "message": "Invalid private key encoding"
    },
    "id": null
}

Please help me, I read lots of code but didn't find solution.
thanks in advance
