Parse DB Tips

Include multiple pointer in a query.

query.include([’pointer1′, ‘pointer2′]);

Chain equalTo

query.equalTo(’table1′, pointer1).equalTo(’table2′, pointer2)

Parse has its own Promises

return Parse.Promise.error(”Error Message”);

Take note of queries results, even if the length of the result is 1, it is still in an array.

Paypal express checkout setup

A good walkthrough for payment process can be found here.

https://devtools-paypal.com/guide/expresscheckout/php

Setting up paypal express with nodejs (server side)

var request = require('request'); var querystring = require('querystring');

var data = { USER: "", // user id PWD: "", // password SIGNATURE: "", // signature VERSION: 95,  METHOD: "SetExpressCheckout", PAYMENTREQUEST_0_AMT: 123, // payment amount PAYMENTREQUEST_0_PAYMENTACTION: "SALE", // type of transaction PAYMENTREQUEST_0_CURRENCYCODE: "USD", // payment currency code returnUrl: "", // after payment cancelUrl: "" // cancel  }

request.post({url:'https://api-3t.sandbox.paypal.com/nvp', form: data}, function(err,httpResponse,body){ var redirectUrl = "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=" + querystring.parse(body).TOKEN; });

After payment is completed, paypal will redirect the user to ‘returnUrl’ with TOKEN and PAYERID. From there you can check the details of the payment.

var checkPayment = { USER: "", // user id PWD: "", // password SIGNATURE: "", // signature VERSION: 95, METHOD: "GetExpressCheckoutDetails", TOKEN: "" // the token you received }

request.post({url:'https://api-3t.sandbox.paypal.com/nvp', form: checkPayment}, function(err,httpResponse,body){ console.log(querystring.parse(body)); });

Integrating Unity3d Into iOS UITabBarController / UINavigationController

Assuming you integrated unity with your project and there is no compiling errors. There are 3 files you have to modify in order to get this to work. I’m using Unity v5.0.0f4 and XCode 6.3.1. There are quite some changes in Unity’s v5 and v4. One main change is the createHierarchy is deprecated and you will have to use willStartWithViewController.

[main.mm]

In the main function inside main.mm file, edit with the extended “UnityAppController” class.  

  UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String:AppControllerClassName]);

[YourUnityAppController.mm] 

This is the file where you create in unity under Plugin/iOS/YourUnityAppController.mm 

This initializes the rootController and rootView used by Unity. We will not do anything else here.

- (void)willStartWithViewController:(UIViewController*)controller {

   _rootController = [[UIViewController alloc] init];

   _rootView       = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

}

In your didFinishLaunchingWithOptions method create an observer. We will need to use this to listen when Unity is being created completely and then set our windows rootView with anything we want.

The process is as follow

- didFinishLaunchingWithOptions will call its super class which will invoke “willStartWithViewController”. Which means anything below the super class constructor will be invoked after “willStartWithViewController” is finished. 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

   [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleUnityReady) name:@"UnityReady" object:self];

   [super application:application didFinishLaunchingWithOptions:launchOptions]

}

And our method to handle the observer.

- (void)handleUnityReady {

   _window.rootViewController = yourTabBarController;

}

This prevents Unity from overriding your view with its view when the app launches.

[UnityAppController.mm]

Inside this file locate startUnity function. We will need to add our callback in there. Make sure it is added after [self showGameUI]

   [[NSNotificationCenter defaultCenter] postNotificationName:@"UnityReady" object:self];

That is it! The Unity view is being created but not on top of your application. You can then grab the Unity view using GetAppController().unityView and assign it to any view you want.
