N=24 - a SplitViewPresenter - N+1 Days of MvvmCross

As a first step in talking about custom presenters, I created N=24 - a splitview sample.


This sample shows how to create a presenter which allows the same Views and ViewModels to be used in different ways on the iPhone and iPad:

N=23 - Dialogs - N+1 Days of MvvmCross

Sorry for the lack of new videos...


Just a bit busy right now - including with some time off :)


Today's video covers the MonoDroid and MonoTouch Dialogs in the 3.0.7 nuget MvvmCross packages


I may have been a little blasé in my intoduction today - I may have assumed that everyone knows what dialogs are already....


If the mention of Dialog makes you think 'what's a Dialog?' then it might be best to start with an introduction to Dialogs... so maybe start with Nic Wise's slides at:

- http://fastchicken.co.nz/2013/04/20/xamarin-evolve-talk-fast-ui-creation-with-monotouch-dot-dialog/

(video of his talk is also coming soon on http://xamarin.com/evolve/2013)



If, however, you are already familiar with Dialogs, then here's the MvvmCross action:

N=22 - From basics on the Mac (N+1 Days of MvvmCross)

Today's screencast is in response to a question on StackOverflow - http://stackoverflow.com/questions/16703828/mvvm-cross-support-for-xamarin-studio-on-a-mac


This possibly isn't as long-term a fixture in the N+1 collection as the other videos... but it shows how you can use MvvmCross on the Mac for both iOS and Android if you want to.


The current Xamarin PCL situation is changing... so I very much hope this video will be out of date very soon indeed!

Preserving data during Xamarin.Android debugging - e.g. keeping your SQL and your settings files

Great advice from http://stackoverflow.com/questions/16695739/doesnt-create-save-database

To preserve data and cache data between application installs:

In Visual Studio:

  • Click Tools > Options...
  • In the left-hand tree, select Xamarin > Android Settings
  • In the right-hand panel, select [X] Preserve application data/cache on device between deploys.

In Xamarin Studio:

  • Click Tools > Options (Windows) or Xamarin Studio > Preferences (OS X)
  • In the left-hand tree, select Projects > Android
  • In the right-hand panel, select [X] Preserve data/cache between application deploys.

N=21 - Internationalisation - i18n - N+1 days of MvvmCross

Today I talk through an introduction about how to provide some localised text to your UI.


The code for today is at: https://github.com/slodge/NPlus1DaysOfMvvmCross/tree/master/N-21-Babel


The slides are on: https://speakerdeck.com/cirrious/internationalization-in-mvvmcross






Today I tried a slightly different style - I tried slides and a pre-built demo. Let me know what you think of this style - is it useful? Better? Worse? Different?
Coming up soon.... more on custom controls, and then time for custom presenters too - tabs, panoramas, hamburger-slideout-views, etc...

Using PP files to make nuget packages more consumable - @dsplaisted hits **4**

Over the last five months of handing out MvvmCross Badges of Awesomeness, only three have been awesome enough to hit 3 badges....

And one of them, @dsplaisted, today hits 4!

Previously in 'The evolution of Dan'


Daniel's been a great supporter of the project and he's previously contributed awesome things like:


And recently, he's made another awesome contribution - this issue which pointed out how to use .pp source code transformations in nuget in order to make MvvmCross project start even simpler.


This has had a big impact - especially when combined with @Cheesebaron's res-auto change. Thanks to these changes, starting a WindowsPhone, WindowsStore, Android or iOS is now really simple.


This is awesome.... and so Daniel...  it's an absolute pleasure to award you badge number 4

Triple Cheese - res-auto makes Android resource coding ten times easier

The awesome @CheeseBaron bags a third badge of awesomeness for helping out the project with this line of magic xml:


    xmlns:local="http://schemas.android.com/apk/res-auto"
 


This simple res-auto change has made a big difference to MvvmCross Android resource coding - it's awesome!


If you do Xamarin.Android coding and you don't already follow CheeseBaron's blog and GitHub account, then you're missing out on some fab control action...


@CheeseBaron - MvvmCross salutes and thanks you for a third time - triple-awesome-cheese:

N=20 - Custom Controls on WindowsPhone - N+1 Days of MvvmCross

Of all the platforms, WindowsPhone is the one I probably know best... However, as I found out recording N=20, there are still gaps in my knowledge here :)


This talk follows on from N=18 and N=19 - we add the same some custom label and 'custom draw' shape controls as we added for iOS and Android. "Modern Windows" seems to be a bit unusual in this area - it's less about draw onto a Graphics Context and more about using a pre-built Canvas. And I clearly am not a DependencyProperty fan :)



I may have gotten some thing wrong during this recording - for more expert Windows advice... check out http://www.geekchamp.com/

N=19 - Custom Controls on iOS - N+1 days of MvvmCross

Following on from N=18, I implemented the same 2 Custom Controls in iOS:

  • a subclassed UILabel
  • a custom drawn UIView

N=18 - Android Custom Controls (N+1 Days of MvvmCross)

Today's short video shows two techniques for implementing custom controls in Android.




  • The first is `SubClassing` - which implements a control by inheriting from an existing one.
  • The second is `Custom Draw` - inheriting from View and then overriding the Draw method.


The video is:

N=17 - From WP and Android to Touch (N+1 days of MvvmCross)

Finally... after a gap of a week we're back.


Sorry about the delay - it's mainly due to the fabulous training day we did on Monday in London, coupled with quite a lot of time that I've spent on customer projects.


Today's N+1 is about porting to iPhone:

  • Takes the Collect-A-Bull app from N=16
  • Briefly recaps over the WindowsPhone and Android functionality (apologies for some recording glitches here)
  • Adds a new iPhone project
  • Adds the plugins to it
  • Switches to the Mac where we add some views using XIBs (and we hit a 'freeze' within Mac OSX too!)
  • Switches back to the PC where we add the data-bindings for those views
  • Finishes with some debugging


I possibly rushed this step a little too much... I also possibly added some lines about ValueConverters that I didn't need to - adding some confusion - sorry!


Overall, though, I hope this is useful and I hope it brings Collect-A-Bull to a reasonable conclusion :)


Here's the video:

N=16 - Taking Collect-A-Bull from WindowsPhone to Xamarin.Android (N+1 days of MvvmCross)

Today we took the output of N=15 and ported it to Android


Before we started, we upgraded our projects to the latest MvvmCross packages - on NuGet with version 3.0.6


Once we started on Droid, it was mainly a case of converting Xaml to Axml, but we did hit a few tricky points along the way - especially around Images and Location - we'll come back to look at some of these in N=17.
