Sign Message and Verify

Sign message​

Use UniPass Wallet to sign the specified message, which can be done by calling signMessage. There are two message signature methods, PersonalSign and SignTypedData

Definition of signature function​

public enum UniPassSignType: String {
    case PersonalSign
    case SignTypedData
}

public class UniPassSignInput: NSObject {
    public var from: String = ""
    public var type: UniPassSignType = .PersonalSign
    public var msg: String = ""
}

Code sample​

// Ensure that the user is authorized to log in
if let userInfo = unipassSdk?.getUserInfo() {
    let signInput = UniPassSignInput()
    signInput.from = userInfo.address
    signInput.type = UniPassSignType.PersonalSign
    signInput.msg = signTextField?.text ?? "Test Sign Message"
        
    unipassSdk?.signMessage(signInput, SuccessBlock: { signature in
        print("unipassSdk: sign message successfully ✅", signature)
        self.signatureLabel?.text = signature
    }, ErrorBlock: { error in
        print("unipassSdk: sign message failed ❎", error)
    })
} else {
    print("unipassSdk: user not login ❎")
}
