IBM Domino Designer Tip: Change measurement for notes-based designs

This is a quick tip for those who want to change the unit of measure in IBM Domino Designer from inches to centimeters.

Inches are a default for IBM Domino Designer when setting up table designs and the like in Notes, but I prefer to use centimeters. To modify the measurement, do the following:

  1. Open Domino Designer
  2. Click on “File\Preferences”
  3. Select “Regional Settings”
  4. Select which Unit of Measurement you want to use
  5. Click on “Ok”
  6. Restart Domino Designer

Webstorm Tip: Use Key Promoter to help you find Keyboard shortcuts

For me, there are too many keyboard shortcuts to memorise in Webstorm IDE? Thanks to a nifty plugin, these shortcuts can be learnt on the fly.

Overview

What Key Promoter does is monitor your mouse clicks on Menus and Toolbars inside Webstorm. If a shortcut exists for where you mouse-clicked, Key Promoter will show you the Keyboard Shortcut command that you can use for that same action.

Firstly, where to find references to Keyboard Shortcuts

Note: The below instructions are for Mac, but Windows will be very similar.

  • Top Menu > Help > Default Keymap Reference
  • Top Menu > Preferences > Keymap
  • Keyboard: CMD + SHIFT + A (For Mac)
  • Keyboartd: CTRL + SHIFT + A (For Windows)

To install Key Promoter

Note: The below instructions are for Mac, but Windows will be very similar.

  • Go to the Webstorm Preferences: Top Menu > Preferences
  • Search for “Plugins”
  • Click on “Browse Repositories”
  • Search for “Key Promoter”
  • Click on Install Plugin
  • Restart Webstorm

Webstorm

Test Key Promoter

After restarting Webstorm, you can test Key Promoter by performing the following mouse actions below:

  • Clicking on the Changes Tab at the bottom of the Webstorm IDE

Webstorm2

  • Clicking on the Git Update Project icon on the top right of the Webstorm IDE

Webstorm3

Closing

I trust this tip will help you be more productive when developing? Stay tuned for more.

Cheers for now

Appcelerator fix for Ti.Map on iOS after upgrading to Titanium 3.4.0

This is a quick tip on how to get Ti.Map working again on your iOS7 builds after upgrading Titanium to SDK 3.4.0.

Quick Note

For the sake of those who just want to know how to fix the problem and not why it occurred, I will commence this post with the fix and then after that explain what I assumed happened.

Also, thanks to Tim Poulsen and Boydlee, please see below Option 1 on how to resolve this issue best. I’ve kept my option as Option 2

How to fix the issue – Option 1 (Thanks to Tim and Boydlee)

  • In Titanium Studio, open the tiapp.xml file in your mobile project
  • Under the Modules section, double click on the entry “ti.map”
  • Change the version to 2.0.2 (Which seems to be the version that will work with SDK 3.2.0 and up)

TiMap5

How to fix the issue – Option 2

  • In Finder, navigate to “Library > Application Support > Titanium > modules > iphone > ti.map
  • Starting with the latest version of Ti.Map, open the relevant folder (e.g. 2.0.5)

TiMap

  • Open the manifest file using TextEdit
  • Check the mindsdk property. If it says 3.4.0, then it will only work for iOS 8 Builds

TiMap2

  • If you want to still develop for iOS7 and use Ti.Map globally for all your apps, then you will need to delete the version of Ti.Map relevant to the above-mentioned
  • In my case, I needed to delete the 2.0.4 and 2.0.5 folders. Now, my latest version of Ti.Map is 2.0.2

The error I was getting

I mentioned in a previous post of mine, that the reason I upgraded Titanium Studio to version 3.4.0, was because Xcode 6 silently installed itself on my machine. When I upgraded Titanium to 3.4.0, I got the following error message when trying to run a build for an iOS7 app that makes use of the Ti.MAP module:

TiMap3

 

My assumption of what happened

So, here’s a shot in the dark of what happened. When upgrading to Titanium Studio 3.4.0, Appcelerator saw that I had the Ti.Map module (which Appcelerator developed) and immediately downloaded the latest version (2.0.4 or 2.0.5), which I assume is required for iOS 8 development.

The truth is, I can’t remember what version of Ti.Map I installed last, but I do know that it was working. When I opened the modules folder on my Mac, the latest version was 2.0.4.

At this time I thought that maybe I downloaded 2.0.4 a while ago, and during the update of Titanium Studio this module was modified accidentally by the update.

My first attempt to fix the problem

First thing I did was check on Github what the latest version of Ti.Map was. I noticed 2.0.5 was released and downloaded that to my modules folder.

Sadly this did not fix the problem. I still received the same error as before.

My second attempt to fix the problem

I got a bit clever and opened the manifest file for version 2.0.5. I noticed that the minsdk parameter had a value of 3.4.0. I changed this to 3.2.3.

The good news is that my app was successfully running again. The bad news is that when launching any window that made use of the Ti.Map module I got the following error:

TiMap4

It was here that I finally made the assumption that Ti.Map 2.0.4 was automatically downloaded, as it contains code that only works in XCode 6.

My third attempt which finally fix the problem

What I did next was started from the latest version of Ti.Map, and checking backwards which version had a minsdk lower or equal to 3.2.3. In my case, it was version 2.0.2 of Ti.Map. So I deleted the 2.0.4 and 2.0.5 folders, reran my iOS7 build and Boom. Everything is working again.

I hope this helps everyone. I welcome any input that would assist in understanding what happened here.

Cheers for now

Appcelerator Tip: Switch between iOS SDKs for mobile app development

Thanks to Apple forcing my hand by auto installing Xcode 6, I had to quickly manage multiple versions of Xcode on my mac for Appcelerator mobile development.

Why multiple versions?

Xcode 6 has the iOS 8 SDK and Simulator by default. For some reason, I couldn’t get it to include the iOS7 SDK, which is what I require for my current development projects. This meant that I needed Xcode 5 back on my machine. I was quite nervous to delete Xcode 6 and replace it with Xcode 5 again, so I decided to install multiple versions of Xcode instead.

My first attempt failed

My first attempt was to do the following (Note: Here’s my blog post on how to achieve the below-mentioned):

  • Download Xcode 5.1.1 from the Apple Developer Center
  • Extract the 7.1 SDK and Simulator from Xcode 5.1.1 and paste it into Xcode 6
  • Restart Titanium Studio

This used to work in the past, but not this time. I kept getting random errors that I  haven’t seen before.

My second attempt succeeded

Thankfully, there’s more than 1 way to skin a cat. The following worked for me:

  • Download Xcode 5.1.1 from the Apple Developer Center Website (I named the file “xcode_5.1.1.dmg“)
  • Double click the DMG file and drag the “XCode.app” icon on to the “Applications” icon.
  • When prompted if you want to “Replace” or “Keep Both” files, choose “Keep Both“.

Apple1

 

  • Once the copy is complete, navigate to the Applications Folder and rename the new Xcode2.app to “Xcode511.app”

Apple2

Now, what we need to do is tell Titanium which Xcode to point to. By default, Titanium looks at the default “Xcode.app” file in the Applications folder. In this scenario, we want Titanium to point to the “Xcode511.app”.

To achieve this, do the following:

  • Open Terminal
  • Type in “sudo xcode-select -switch /Applications/Xcode511.app/Contents/Developer”
  • Restart Titanium Studio
  • In the Top Menu, navigate to “Titanium Studio > Preferences > Studio > Platforms > iOS”
  • Next to iOS SDK Home, click on the “Refresh” button.

And that’s it. Hopefully this will do the trick for you as well.

Till next time
