CoboSDK帮助开发者通过Cobo钱包进行ethereum交易的签名和发送。 DApp开发者可以使用CoboSDK获取用户的ethereum账户地址，完成消息的签名和校验，发起交易、调用智能合约以及广播签名后的交易数据。从而省去了开发者自行实现用户私钥管理和钱包功能的工作。

接入CoboSDK需要如下几个步骤：
- Cocoapods
在你的Podfile中添加：
pod 'CoboSDK'然后在终端中执行$ pod install
- Carthage
TODO
在Xcode中，选择工程设置项，选中TARGETS，打开Info标签页，点击URL Types中的+按钮添加新的URL Type。在URL Schemes 中填入应用的URL Scheme。URL Scheme应当尽可能唯一，建议使用<Bundle ID>.cobo。
注册URL Scheme到CoboSDK中，这里的URL Scheme应当与URL Type中添加的URL Scheme相同。
CoboSDK.shared.setup(callbackScheme: <replace with your url scheme>)在应用的Info.plist文件中，添加如下内容：
<key>LSApplicationQueriesSchemes</key>
<array>
<string>cobo-wallet</string>
</array>
实现AppDelegate中的func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool方法来接收返回的结果数据：
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
return CoboSDK.shared.application(app, open: url, options: options)
}let message = "Hello Cobo!"
CoboSDK.shared.signMessage(message: message) { result in
switch result {
case .success(let value):
guard let address = value.address, let signature = value.signature else { break }
print(address)
let match = CoboSDK.shared.verifyMessage(address: address, signature: signature, message: message)
print("\(match)")
case .failure(let error):
print(error.localizedDescription)
}
}let gasPrice = BigUInt(stringLiteral: "1000000000") // 1 Gwei
let gasLimit = BigUInt(21000)
let value = BigUInt(stringLiteral: "1000000000000000000") // 1 ETH
let from = <replace with address in sign message result>
let to = <replace with address to transfer to>
let tx = EthereumTransaction(gasPrice: gasPrice, gasLimit: gasLimit, to: to, value: value, data: Data())
CoboSDK.shared.sendTransaction(transaction: tx, from: from) { result in
switch result {
case .success(let value):
guard let hash = value.hash, let tx = value.rawTransaction else { break }
print("hash: \(hash)")
case .failure(let error):
print(error.localizedDescription)
}
