ios - 如何在 Swift 4 中将比特币从一个钱包发送到另一个钱包

Question

我正在开发一个自定义比特币钱包，我可以使用 Yenom/BitcoinKit 生成公钥/私钥。我需要将 BTC 发送到我尝试使用的另一个钱包 BitcoinKit .但是我无法发送 Btc。我该怎么做呢？我们可以使用 BitcoinKit 以外的另一个库将 Btc 从一个钱包发送到另一个钱包吗？

So how do I transfer BTC from one wallet to another in Swift, please advise.

有一个函数叫做sendToSomeAddress

private func sendToSomeAddress(_ amount: Int64) {
        let toAddress: Address = try! AddressFactory.create("bchtest:qpytf7xczxf2mxa3gd6s30rthpts0tmtgyw8ud2sy3")
        let changeAddress: Address = try! AppController.shared.wallet!.changeAddress()

        var utxos: [UnspentTransaction] = []
        for p in payments {
            let value = p.amount
            let lockScript = Script.buildPublicKeyHashOut(pubKeyHash: p.to.data)
            let txHash = Data(p.txid.reversed())
            let txIndex = UInt32(p.index)
            print(p.txid.hex, txIndex, lockScript.hex, value)

            let unspentOutput = TransactionOutput(value: value, lockingScript: lockScript)
            let unspentOutpoint = TransactionOutPoint(hash: txHash, index: txIndex)
            let utxo = UnspentTransaction(output: unspentOutput, outpoint: unspentOutpoint)
            utxos.append(utxo)
        }

        let unsignedTx = createUnsignedTx(toAddress: toAddress, amount: amount, changeAddress: changeAddress, utxos: utxos)
        let signedTx = signTx(unsignedTx: unsignedTx, keys: usedKeys())

        peerGroup?.sendTransaction(transaction: signedTx)
    }
