Extend your iOS Toolbox

Published November 16, 2018 by Xojo

Developing for iOS with Xojo can be quick and easy, but if you need more power for your app’s controls, your options are:

  • study the Apple documentation, which can take time and building the right declares from scratch is not trivial; or
  • use one of the many open source projects, though you may end up having to import things that you don’t want or need;

If you don’t have the time or inclination for these options, Falco Software’s extensions could be what you are looking for. The extensions work similarly to Xojo, just drag the control and start developing. No alien objects to create, no extra code to maintain. Here are some examples of where Falco Software’s extensions can simplify and speed up your iOS development.

#JustCode Challenge Week 14 – Marching Band ScoreKeeper

#JustCode Challenge Week 14 – Marching Band ScoreKeeper

Published September 21, 2018 by Paul Lefebvre

For the final week of the #JustCode Challenge I’ve made an iOS app that keeps the score for high school marching band shows. The ScoreKeeper app lets you add a show or event and then set the scores when they are announced at the end of the show. Though this is for marching band, it can easily be adjusted to keep track of a set of scores for any sort of competition or game.

#JustCode Challenge Week 13 – Xojo Speed

#JustCode Challenge Week 13 – Xojo Speed

Published September 14, 2018 by Paul Lefebvre

When Geoff and I were driving around Germany with Christian Schmitz of MBS Software before the MBS Xojo Conference started, the topic of speed limits on the autobahn came up. Christian mentioned than many cars in Germany have the speedometer set to display a speed that is a little higher than what you are actually doing. I have noticed that my Toyota Tacoma shows 70mph on the speedometer when it is really going more like 67.

Geoff wondered if there was a way to determine how accurate your car’s speedometer was and it made me think of a Xojo iOS app I had made a while ago: Xojo Speed.

Run Xojo Speed on your iPhone while you’re driving and it uses the iOSLocation class to calculate the miles per hour or kilometers per hour in a large, easy-to-read display.

#JustCode Challenge Week 12 – MultiTemp

#JustCode Challenge Week 12 – MultiTemp

Published September 7, 2018 by Paul Lefebvre

It’s week 12 of #JustCode and I’m in in Munich, Germany at the MBS Xojo Developer Conference! I’ve never been to Germany and had no idea what the temperature would be, so instead of using the Weather Channel, I found a web API called OpenWeatherMap and built an iOS app to fetch the weather for display in a table. I even implemented the new table refresh feature added to Xojo 2018r2.

#JustCode Challenge Week 4 – Mini Golf ScoreKeeper

#JustCode Challenge Week 4 – Mini Golf ScoreKeeper

Published July 13, 2018 by Paul Lefebvre

Sometimes the idea for a great little app comes down to solving a silly little problem.

Last month, the family went mini-golfing for my son’s birthday. It was a lovely course called Pirate’s Cove Adventure Golf right next to the ocean. But they didn’t have scoring stands and we had to use a tiny pencil on a little cardboard scorecard to keep score. So this week’s app is a simple iOS app track of mini-golf scores!

The iOS app has two screens. The main screen has a giant Table that lists all the 18 holes. You tab on the detail button for a row (it’s the “I” icon) to go to the scoring screen.

5 Questions to Ask When Choosing a Development Tool

These days everyone has a great idea for an app. Maybe you have an idea that would save you time at work, or maybe you’ve been thinking of an app that would automate something you do at home. Not sure where to start? One of your first steps is choosing a development tool that is right for you and for your project.

Here are five questions to guide your decision:

Set Focus to a Field Using an iOS Declare

Published April 12, 2018 by Paul Lefebvre

You can call into Cocoa Touch APIs to use methods and properties that are not built into the framework by using the Declare command. To create a Declare statement you first need to track down the API you want to use in Apple’s documentation: Apple Developer Documentation. Most of the time you will reference the Foundation and UIKit libraries, but there are many other libraries as well. Xojo Declares use the Objective-C names so be sure to refer to those in the documentation rather than the Swift naming.

10 Print

Published November 10, 2017 by Paul Lefebvre

The other day I saw this article on Dev.To: A Universe in One Line of Code with 10 PRINT

It talks about how you could make a maze-like structure on a Commodore 64 with just this one line of code:

10 PRINT CHR$(205.5+RND(1)); : GOTO 10

The author then goes on to show you how you might do something similar using Python and pygame.

I love all things retro and this seemed like fun, so I thought I would whip up the same thing in Xojo.
