TokenCore -- iOS上的区块链私钥管理库

TokenCore是一个区块链库。TokenCore提供了相对一致的API，允许您同时管理钱包并在BTC，ETH和EOS链中签署交易。此外，TokenCore引入了“身份”的概念，您可以使用相同的助记符来管理三个链上的钱包。

安装

要安装TokenCore，请使用CocoaPods并将其添加到您的Podfile：

pod "TokenCore", git: "https://github.com/consenlabs/token-core-ios.git", branch: "master"

Try the API

创建新身份并派生eth，btc钱包

// 在创建其他钱包之前，您应首先创建或恢复身份
do {
  var metadata = WalletMeta(source: .newIdentity)
  metadata.network = Network.mainnet
  metadata.segWit = .p2wpkh //// .p2wpkh意味着派生的btc钱包是SegWit钱包
  metadata.name = "MyFirstIdentity"
  let (mnemonic, identity) = try Identity.createIdentity(password: TestData.password, metadata: metadata)
  let ethereumWallet = identity.wallets[0]
  let bitcoinWalelt = identity.wallets[1]
} catch {
  print("createIdentity failed, error:\(error)")
}

输出钱包（Export Wallet）

let prvKey = try WalletManager.exportPrivateKey(walletID: ethereumWallet.walletID, password: TestData.password)
print("PrivateKey: \(prvKey)")
let mnemonics = try WalletManager.exportMnemonic(walletID: ethereumWallet.walletID, password: TestData.password)
print("Mnemonic: \(mnemonics)")
let keystore = try WalletManager.exportKeystore(walletID: ethereumWallet.walletID, password: TestData.password)
print("Keystore: \(keystore)")

// output:
// PrivateKey: f653be3f639f45ea1ed3eb152829b6d881ce62257aa873891e06fa9569a8d9aa
// Mnemonic: tide inmate cloud around wise bargain celery cement jungle melody galaxy grocery
// Keystore: {"id":"c7575eba-3ae3-4cc3-86ba-2eb9c6839cad","version":3,"crypto":{"ciphertext":"7083ba3dd5470ba4be4237604625e05fa6b668954d270beb848365cbf6933ec5","mac":"f4f9ea8d42ff348b11fc146c396da446cc975309b3538e08a58c0b218bddd15d","cipher":"aes-128-ctr","cipherparams":{"iv":"db3f523faf4da4f1c6edcd7bc1386879"},"kdf":"pbkdf2","kdfparams":{"dklen":32,"c":10240,"prf":"hmac-sha256","salt":"0ce830e9f888dfe33c31e6cfc444d6f588161c9d4128d4066ee5dfdcbc5d0079"}},"address":"4a1c2072ac67b616e5c578fd9e2a4d30e0158471"}

签署交易（SignTransaction）

let signResult = WalletManager.ethSignTransaction(
        walletID: String,
        nonce: String,
        gasPrice: String,
        gasLimit: String,
        to: String,
        value: String,
        data: String,
        password: String,
        chainID: Int
      )
let signedTx = signResult.signedTx //这是您需要广播的签名结果。
let txHahs = signResult.txHash //这是txHash，您可以使用它来查找您的交易记录

故障排除 （Troubleshooting）

For macOS 10.14 Mojave and Xcode 10, install /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg since Xcode command line tools don't install to /usr/include anymore.
