This app demonstrates how to use the SLPWallet iOS SDK in a wallet. With it, you can:
- Receive SLP tokens.
- Send SLP tokens.
- Receive BCH to fund your SLP transfers.
- View your token balances.
- View your BCH balance.
- View your mnemonic to backup your wallet.
- Restore your wallet from a mnemonic.
You can create an SLP wallet in a few lines only. This code comes from WalletManager.swift. All other files are UI related code and don't concern the SDK.
//
// ...
//
import SLPWallet
//
// ...
//
class WalletManager {
static let shared = WalletManager()
var wallet: SLPWallet
var observedToken: BehaviorRelay<SLPToken>?
var observedTokens: PublishSubject<SLPToken>?
init() {
do {
wallet = try SLPWallet(.mainnet)
setup()
} catch {
fatalError("It should be able to construct a wallet")
}
}
//
// ...
//
}
extension WalletManager: SLPWalletDelegate {
// Call with SLPWalletDelegate ❗️💥🚀
func onUpdatedToken(_ token: SLPToken) {
// Notify
if let observedToken = self.observedToken
, observedToken.value.tokenId == token.tokenId {
observedToken.accept(token)
}
// Notify
if let observedTokens = self.observedTokens {
observedTokens.onNext(token)
}
}
}After creating your wallet, you can start sending tokens. This file describes how to send tokens: SendTokenInteractor.swift. Below you can see a preview of the file.
//
// ...
//
class SendTokenInteractor {
fileprivate let bag = DisposeBag()
func sendToken(_ tokenId: String, amount: Double, toAddress: String) -> Single<String> {
return Single<String>.create { single in
WalletManager.shared.wallet
.sendToken(tokenId, amount: amount, toAddress: toAddress) // That's it 💥🚀
.subscribe(onSuccess: { txid in
single(.success(txid))
}, onError: { error in
single(.error(error))
})
.disposed(by: self.bag)
return Disposables.create()
}
}
}
