Swift - Displaying Actionsheet for Ipad and Iphone

Swift - Displaying Actionsheet for Ipad and Iphone

A simple tutorial on making an alert view of type action sheet that works for iphone and ipad.

1.) First you'll need a button where you can attach your pop over when you're using iPad (in iPhone it not necessary). Then you'll have to create an outlet for the button (in my example i named it "btn_button") so we can determine the pop over location based on where the button is placed inside the viewcontroller.

2.) Inside the button's action, paste the following lines of code:

 let optionMenu = UIAlertController(title: "Choose Your Option", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
        let option1 = UIAlertAction(title: "Option 1", style: .Default, handler: {
            (alert: UIAlertAction!) -> Void in
            println("Option 1")
        let option2 = UIAlertAction(title: "Option ", style: .Default, handler: {
            (alert: UIAlertAction!) -> Void in
            println("Option 2")
        let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: {
            (alert: UIAlertAction!) -> Void in
        if ( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.Pad )
            if let currentPopoverpresentioncontroller = optionMenu.popoverPresentationController{
                currentPopoverpresentioncontroller.sourceView = btn_button
                currentPopoverpresentioncontroller.sourceRect = btn_button.bounds;
                currentPopoverpresentioncontroller.permittedArrowDirections = UIPopoverArrowDirection.Up;
                self.presentViewController(optionMenu, animated: true, completion: nil)
            self.presentViewController(optionMenu, animated: true, completion: nil)
The code is pretty straight forward:
-First we declare a UIAlertController where we can put our buttons.
-Second we created the buttons (Option1, Option2, and Cancel) and then we add the buttons inside the alert controller.
-Last we use the UI_USER_INTERFACE_IDIOM to determine if the device/emulator is an ipad or an iphone and do the necessary presentation for each particular device.

How to migrate your Godaddy web hosting to DigitalOcean

Lately I've been reading some good articles about DigitalOcean as a cheap VPS option in online hosting and so I decided to try and subscribe to one.

Since my wordpress website hosting is already expiring I decided to moved the hosting to DigitalOcean and renew the domain name in Godaddy.

Here's how I point my Godaddy domain to DigitalOcean VPS hosting and migrate my wordpress website:

*You must already have a DigitalOcean account with linked payment method (can be either a credit card or paypal).
*Copy all your wordpress files from Godaddy.
*Make a backup of your wordpress database.

  1. Create a droplet in digital ocean.
    1. Distribution = 15.04 x64
    2. Applications = Wordpress 14.04
    3. I chose $5 / month
  2. Follow this article to configure your server:
  3. Migrating your wordpress website:
    1. Using winscp, upload your files in your server's /var/www folder.
    2. Make sure that www-data user can write to the folders where it needed to, for example uploads. Note: use chmod. Note by default the uploaded files are owned by root, use chown and change the ownership to www-data.
      1. >chown www-data:www-data /var/www -R, change the owner and group of /var/www folder from root to www-data. This is done recursively.
      2. >chmod 774, means owner and group (read, write, execute) while others (read-only).
    3. Following the tutorial in #2, you should now have phpmyadmin installed. Restore your wordpress backup.
  4. We then need to point your domain name to the new ip address in digital ocean.
    1. To get your droplet's ip address, go to your digital ocean's droplet's page 
  5. Now that you have your ip address, go to DNS, and add a domain record like this: 
  6. We are done with digital ocean and we will now point godaddy's domain to digital ocean's server.
  7. In Godaddy expand Domains tab.
  8. Chose your domain then click Manage.
  9. In Settings tab, under Nameservers click Manage.
  10. Setup Type=Custom, then add the 3 nameservers below
  11. After adding hit SAVE.
  12. You should now see the 3 name servers in the next screen.
Wait for 5minutes, then try logging-in in your linux hosting, and in the terminal run:

The command above should give you your digital ocean's ip address and name servers.

And that's it! Your wordpress website must now be running in digital ocean. That's in less than 30mins :-)

Common problems I've encountered:

  1. 2 widget were broken, need to set the content again
  2. some folders are not writeable when I uploaded need to execute chmod.

What you should know before getting your own website

So you want to get your own website? Do you know what you should take into account before agreeing to have your website created by the experts? You will be tempted by the many offers that website developers have. It is all too easy to get overwhelmed by the stuff of things to do and to put into your website that you may forget to look at the prerequisites. So what should you look into before letting the website masters do their work? Here they are:


Fees. There is an expected amount of money that you will pay when you have your website created and designed. Usually, the package is meant for a year or so with specifications like web hosting and other services tied up with getting a domain name or website. However, there are also fees that you should know, like transfer fees. Transfer fees are fees that you pay when you opted to transfer your domain. Some website designers will charge you 2 to 3 percent more than your registration fees. So make sure that you ask about all the fees, including hidden ones. (Image at text: Fees)

Pay what you consume

Pay only for the year that you consume. When you are about to pay for registering your domain, make sure you check the expiration of the website or domain that you are buying. There are tools over the Internet that you can use to check it. You can readily Google the term “how to determine expiration of a domain or website” and you’ll get numerous helpful results. On the other hand, the webmaster should show what you paid for. If you paid for one year, then it should reflect that it is registered as such. If you paid 5 years, then it should show, too. (Image at text: Pay what you consume)

Keep record private and locked

Keep your records private. Be careful with your domain or website purchase. Make sure that you learn from the experts how to hide or modify your records so that database hackers do not get a hold of your personal data. If you don’t, soon you will receive a lot of spam emails. Make sure that when you do buy a domain, it is you who own the domain and not them representing you. (Image at text: Keep record private and locked)

Keep it locked. After purchasing your domain and have it designed accordingly by the web designers, make sure that you also have it locked. This ensures that your domain is not transferred and you don’t get any surprises of another person claiming your website.

Get your domain auth code

Get the domain or website authorization code. Some websites or domain requires an authorization code, especially when they get transferred. In essence, you should also have it so that you can readily transfer it, should you want to sell the website or domain in later years. (Image at text: Get your domain auth code)

One of the best ways to avoid any problems is to take time in reading the Terms and Conditions before you purchase a website. Ensure that you read everything, even the fine print so you won’t miss anything. Ask as many questions as you can. List down questions that you have and clarify it with the domain registrar before sealing the deal.

Setup wordpress in a sub-domain in Godaddy's windows hosting

This configuration is for windows only.

For example you have domain that is powered by wordpress, you set up permalinks to use postname so post will be accessible at

The problem is when you create a sub-domain, for example and set permalinks like that of the main domain so that you can do SEO. Obviously this will not work as the main domain permalinks will interfere, so you have to set a redirect rule.

Taken into account that it's a windows hosting, therefore we need to configure Web.config rather than .htaccess.
<?xml version="1.0" encoding="UTF-8"?>

        <rule name="wordpress" stopProcessing="true">
          <match url=".*" />
          <conditions logicalGrouping="MatchAll">
            <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
            <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
          <action type="Rewrite" url="index.php" />

Why You Should Create Your Own Website

When you start a business, you would naturally want it to have the opportunity to grow and thrive. Well, one way to open a lot of opportunities for your business is building your own website. In the Internet age, almost everyone can create their own website, whether free or hosted. Why? Why is this the trend? Here are the advantages of having your own website:
communication and professionalism
Communication and professionalism. How can you tell your clients that you are serious with your business? The best way is to get a website for your own. By having a website, you can easily show the professional products and services that your company offers. In addition, you get to communicate with your target audience even when you’re asleep.
increase your coverage area
Advertise anytime, anywhere. When you need to promote a certain discount or service package, you don’t have to print a lot of leaflets and brochures. You just have to design it and post it on your website. Advertising via social media and email is easier since you can easily get the link from your website.

Increase your coverage area. When you print leaflets and brochures or hang an advertisement in your office, how many people do you think will come and inquire about your products and services? With a website of your own, you don’t just get potential clients from your local area, you also get potential clients in and outside your geographical location.

hire people
Start small but grand. A website has a way of showing your company offering a grand scale service even if you are just on the start-up part of your business. With a small capital and good service and product line, you can get potential clients to help your small business grow to your big business dream.

Hire people. One of the best means to hire people for your company is through your website. You can virtually research about the applicants that have applied through your website as well as create a pool of people that you can tap whenever you needed additional people to do a job.
share company news in and around the globe
Share company news in and around the globe. A website usually has a page that provides visitors the latest news about the company. You can share relevant company news, events as well as launch new products and services.
process transactions online
Process transactions online. There are a couple of payment methods available when you already have a website. This makes the payment method for clients easier. In turn, you also don’t have to send people to the client’s area for collection, instead get it immediately in exchange for the products you provide. Instant, hassle-free and paperless transactions. You get to save the environment, too! 
online presence
Online presence. One of the most important aspect of creating your website is having an online presence. This is like having an office or a store that is open for everybody who can surf the Internet. You get to show your products while you are away or doing something more important. It is also a medium for possible partnerships and expansion of your business.

Build your website’s authority and rankings. A website’s authority is dependent on many factors, but mostly this means that your website shows relevant content. It is also affected by the age of your website. A website that stays active for a long time with related and up-to-date content can contribute to your page authority. This page authority contributes to a website’s reliability. When search engines find you relevant and has fresh and up-to-date content, your ranking in search results also improve, thus giving you more advantage. You appear on the first page of search results and you get more visits. More visits mean more potential clients coming to see your website with its products and services.

Therefore, it is vital that you get a website for your business. Contact a good website developer and inquire about website development package. The earlier you decide to get a hosted website, the better are your chances of getting the above mentioned benefits.
