FluentLayout v2.5 Released

It's been a little over a year since the last FluentLayout update, so it seemed like a good time to get some little improvements in. I also definitely want to give a shout out to Diego Ponce de León for prompting some of these changes and helping brainstorm some things! If you're using FluentLayout, I'd definitely love to hear your input on improvements you'd like to see, shortcomings, etc. There's a lot more we can do…

Lambda Expressions, Weak Subscriptions, and MvvmCross...Oh My!

Earlier this week we found ourselves looking into a strange databinding problem, where things were working as expected on devices but not in the simulator. Differences between simulators and devices is certainly not uncommon, but I'm not sure I can recall a time where it was on the device that things were binding correctly, and the simulator that was showing problems. The usual suspect of being a linker issue was off the table, so we had…

Presenters in MvvmCross: Nested Modal Navigation in iOS

When navigating to a new view controller in iOS there are two primary ways to do so: pushing it to the navigation stack (the standard way), or "presenting" it which results in a modal-like experience where the new view comes up from the bottom of the screen. This interaction can be useful to convey context to the user, since it feels like a modal interaction that will return them to the current screen afterwards, rather than…

Presenters in MvvmCross: Navigating Android with Fragments

In my last couple posts on this subject I've mentioned using fragments on Android for navigation. By default MvvmCross will use activities on Android, but as I hope you've learned by now, you can use presenters to customize this sort of thing as much as you'd like. I've found it very difficult (or impossible) to properly achieve the types of fine-grained navigation control I want in my apps by using activities for all my views, which…

Presenters in MvvmCross: Controlling the Back Stack

In my last presenter post I showed how you can use presentation hints to tell the presenter to clear the view stack prior to showing the next view. That is probably the most common custom navigation pattern I've seen used in MvvmCross apps, but I also wanted to note another similar pattern I've used as well. When I'm mapping out the navigation paths through my apps, I try to be very conscious of the state of…
