Today's N+1 is all about whether or not your ViewModel is Visible - and about how to kill it when it gets removed from the screen.
This is a fairly FAQ topic - see questions like http://stackoverflow.com/questions/15961664/viewmodel-lifecycle-when-does-it-get-disposed and http://stackoverflow.com/questions/19816819/how-are-views-and-viewmodels-freed-up-in-mvvmcross
MvvmCross doesn't provide any built-in event notification - but it is easy to add it for your app.
In this video, I show how to add and invoke interfaces like these to some view models which are shown by a standard MvvmCross presenter:
If you have custom presentation, then you'll need to adapt this technique to suit your needs - but, since it is your custom presentation, then you should hopefully be in the best place to do this.

N=41 - More Android maps - more advanced - N+1
Today we carry on to a finalé in our trip through data-bound maps on Android.
This maps tutorial follows on from:
For demos in the video, I use a real device - sorry for the bad camera work!
I also mess up a few times - sorry :)
I also try some really advanced stuff with making a bindable fragment - for which I make no apologies :)
For really working out how to use Google Maps - see https://developers.google.com/maps/documentation/android/views - it's actually very good documentation!

N=40 First Part of Maps on Android - N+1
Today we move on to maps on Android.
This maps tutorial follows on from:
To get maps working we use the Google Play Services component - see https://components.xamarin.com/gettingstarted/googleplayservices for how get started on this.
For demos in the video, I use a real device - sorry for the bad camera work!
If you want to try to get maps working on an emulator, then I recommend you take a look at http://www.genymotion.com/ - although I don't think this plays nicely with the WP8 emulator or with the Intel HAXM driver either :(

N=39 - CrossLight on Xamarin.iOS/MonoTouch (aka Project Chimp)
This video is a follow on from http://slodge.blogspot.co.uk/2013/06/n30-crosslight-aka-project-chimp-n1.html where I showed how to use the MvvmCross binding layer in Android without using the higher layers (the navigation service, the plugin loader, the thread dispatcher, etc).
In this video I quickly do the same thing for Xamarin.iOS.
The process is pretty simple:
1. Add references to the CrossCore and Binding assemblies for MvvmCross (in the video I use nuget CrossCore package - https://www.nuget.org/packages/MvvmCross.HotTuna.CrossCore/)
2. Add a small setup class and call it from your appdelegate start code
3. Add you ViewModel - and INotifyPropertyChanged will do
4. Adjust your ViewController so that it can do data-binding to an instance of your ViewModel
5. Run :)

N=37 - Maps and Zombies part 1 - N+1 Days of MvvmCross
After a slightly longer than planned summer break, I'm finally returning to these recordings. Sorry about the elongated break, but I'm back now, and hoping to cover some more advanced topics :)
To start with, I thought I'd try some mapping. This is going to take a few videos to get completed.... just easing back into this process.
First up:

N=36 - A Rio Binding Carnival :)
Today's N+1 follows on from the previous Tibet video - N=35 - which was all about Views and multibinding.
Rio Binding today is all about ViewModels.
Rio is an attempt to experiment with different types of ViewModel. In particular to:
Using the FieldBinding and MethodBinding plugins from Rio, a view model can look like:
instead of an old-skool-INotifyPropertyChanged ViewModel like:
Rio is an attempt to start a conversation.:
Please note that no-one is saying that Rio field- and method-binding is better than the established property and command binding. All it does for now is to offer some new alternatives. Always think about your code and always choose the tools and techniques which suit you, your team and your app best - the app is king!

N=35 - MultiBinding with Tibet - N+1 Videos of MvvmCross
Fresh from the heat and Summer-sunshine of London, today's N+1 introduces the new 'Tibet' binding engine.
This binding engine is built on top of the old 'Swiss' engine - so should be fully backwards compatible.
In addition to all the awesome syntax you had in Swiss, you can now take advantage of:
There's some good documentation on Tibet binding being authored over on https://github.com/slodge/MvvmCross/wiki/Databinding#tibet
This includes examples like:

In addition to all the awesome syntax you had in Swiss, you can now take advantage of:
- Multi-binding
- Simple combination operators
- The `Format` combination operator
- The `If` combination operator
- Recursive nesting of combinations and of value conversions
- Function-style invocation of value converters
There's some good documentation on Tibet binding being authored over on https://github.com/slodge/MvvmCross/wiki/Databinding#tibet

N=32 - The Truth about ViewModels... starring MvxView on the iPad - N+1 days of MvvmCross
Triggered by a stackoverflow question I thought I'd try to explain that a ViewModel is just a Model for a View.
I'm not sure if I succeeded or not... but at least I got a chance to demo an iPad app - and I got a chance to talk about the very lovely but underused MvxView

N=31 - Injection of Platform Specific Services - N+1 Days of MvvmCross
One of the common questions I get asked is how to consume non-portable functionality into portable class library functionality.
My answer to this is to use dependency injection where possible.
This N+1 covers two ways of doing that:
In my 'real-world' projects I generally:
The video for today is at:
At one point, you see that I have an assembly version mismatch - sorry about this - it's due to me talking from a development rather than production setup, and it was easily solved using the nuget `Update-Package` command to update all my projects to the same MvvmCross NuGet version.

For more on N+1, see:
My answer to this is to use dependency injection where possible.
This N+1 covers two ways of doing that:
- firstly by defining interfaces in the core project, and manually registering implementations in each UI project
- secondly by using testable, reusable plugins
In my 'real-world' projects I generally:
- start with the first approach - it's quick and very easy to do
- migrate to plugins where I find I have functionality I need to test, or if I think that I might want to reuse that functionality across projects
- sometimes, rarely, I do also switch back to non-portable code (to file-linking) for cases where the native API which needs consuming is too large to wrap with an interface - but I try to avoid this wherever possible.

N=30 - CrossLight (aka Project Chimp) - N+1 Days of MvvmCross
This is a very technical topic today.
It's aimed mainly at people who want to use the MvvmCross plugins or the MvvmCross binding layer in non-MvvmCross applications. This may sound isn't something MvvmCross should want... but I would personally love to see lots of small cross-platform application frameworks pushing away at different ideas/areas. Innovation breeds off of invention, and innovation is fun and profitable :)

N=28 - Custom Bindings - N+1 Days of MvvmCross
Today, I thought I'd try something Deeply Technical
Actually it's not that technical... but it's a topic that people might feel a bit nervous about.
There's no need to worry - custom bindings are actually pretty simple.
For most UI controls/widgets in Android and iOS, MvvmCross binding "just works"
It does this using Reflection.
This works brilliantly well for many (most!) controls.
Problems only arise when whoever has written the control hasn't followed this convention - e.g.
In these cases, you can work around the challenge by using a Custom Binding.

Custom Bindings
Actually it's not that technical... but it's a topic that people might feel a bit nervous about.
There's no need to worry - custom bindings are actually pretty simple.
For most UI controls/widgets in Android and iOS, MvvmCross binding "just works"
It does this using Reflection.
- Wherever Mvx sees a property - e.g. public int Count {get;set;} - then it knows it can do one-way binding to it using Reflection.
- Further, when it sees that there is also an event with a name ~Changed - e.g. public event EventHandler CountChanged; - then it also guesses that the event can be used for TwoWay binding too.
This works brilliantly well for many (most!) controls.
Problems only arise when whoever has written the control hasn't followed this convention - e.g.
- if they've just provided arbitrary get/set methods instead of a public C# property
- or if they've decided to signal their changes using a delegate or watcher pattern instead of a C# event.
In these cases, you can work around the challenge by using a Custom Binding.

N=25 - Tabs - N+1 Days of MvvmCross
Following on from splitview presenters, this talk gives an introduction into using tabs on Xamarin.Android, Xamarin.iOS and WindowsPhone.
For WindowsPhone, we use a Panorama as the local equivalent of Tabs - and we also mention Pivots.
For iOS, we show how to use a custom presenter to perform navigation within a tab child.
For Android, we hint at a future discussion of Fragments, but for now we discuss only Activities.

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....
