Use cases

Transfer

[[GXConnectionManager sharedInstance] connectWithFallback:@[@"wss://testnet.gxchain.org"] callback:^(BOOL connected, NSString *url) {
        GXTransferOperation* transferOp=[[GXTransferOperation alloc] init];
        transferOp.from=@"1.2.850";
        transferOp.to=@"1.2.254";
        transferOp.amount=[[GXAssetAmount alloc] initWithAsset:@"1.3.1" amount:1000000];
        transferOp.fee=[[GXAssetAmount alloc] initWithAsset:@"1.3.1" amount:0];
        transferOp.memo=[GXMemoData memoWithPrivate:@"5JNFf2y7JN75HMytcTJVANPVXAzv5iQbxdVDrtJNWfcSsyWUrXU" public:@"GXC7xSR83xcXECGCtyxboNbuhQwnyjVksgtMLX422nDhSM9d2TPRF" message:@"屌不屌，来自GXS Native的转账"];
        GXTransactionBuilder* tx = [[GXTransactionBuilder alloc] initWithOperations:@[transferOp]];
        [tx add_signer:[GXPrivateKey fromWif:@"5JNFf2y7JN75HMytcTJVANPVXAzv5iQbxdVDrtJNWfcSsyWUrXU"]];
        [tx processTransaction:^(NSError* err,NSDictionary *transaction) {
            NSLog(@"%@",transaction.json);
            [expectation fulfill];
        } broadcast:YES];
    }];

CallContract

[[GXConnectionManager sharedInstance] connectWithFallback:@[@"wss://testnet.gxchain.org"] callback:^(BOOL connected, NSString *url) {
        GXCallContractOperation* callOp = [[GXCallContractOperation alloc] init];
        callOp.fee=[[GXAssetAmount alloc] initWithAsset:@"1.3.1" amount:0];
        callOp.account = @"1.2.850";
        callOp.contract_id=@"1.2.282";
        callOp.method_name=@"hi";
        callOp.data=[NSData data];
        GXTransactionBuilder* tx = [[GXTransactionBuilder alloc] initWithOperations:@[callOp]];
        [tx add_signer:[GXPrivateKey fromWif:@"5JNFf2y7JN75HMytcTJVANPVXAzv5iQbxdVDrtJNWfcSsyWUrXU"]];
        [tx processTransaction:^(NSError* err,NSDictionary *transaction) {
            NSLog(@"%@",transaction.json);
            [expectation fulfill];
        } broadcast:YES];
    }];
