回调方法

Question

我想从void发送回叫响应

RCT_EXPORT_METHOD(checkOut:(RCTResponseSenderBlock) callback){

}


- (void)paymentViewController:(PaymentViewController *)viewController paymentSuccess:(TransactionResult *)result {
NSLog(@"success: %@", result);
}

- (void)paymentViewController:(PaymentViewController *)viewController paymentFailed:(NSError *)error {
[self showAlertError:error];
}

- (void)paymentViewController:(PaymentViewController *)viewController paymentPending:(TransactionResult *)result {
NSLog(@"pending: %@", result);
}

- (void)paymentViewController_paymentCanceled:(PaymentViewController *)viewController {
 NSLog(@"canceled");
}

当我运行react-native run-ios时 NSLog不再显示为日志。

关于本机代码

const callback = (result) => {
        console.log(result)
    };

Payment.checkOut(callback);

但是我需要回调响应， 所以我可以通过条件 喜欢

if(result === "canceled")
