iOS support packages for MvvmCross: The .NET MVVM framework for cross-platform solutions

MvvmCross

👀 Check out mvvmcross.com to get started with MvvmCross 👀

MvvmCross is a opinionated cross-platform MVVM framework. It enables developers to create apps using the MVVM pattern in the .NET ecosystem. We support Android, iOS, MacCatalyst, TvOS, macOS, WinUI, WPF. Using MvvmCross allows for better code sharing by allowing you to share behavior and business logic between platforms.

Among the features MvvmCross provides are:

• ViewModel to View bindings using own customizable binding engine, which allows you to create own binding definitions for own custom views
• ViewModel to ViewModel navigation, helps you share behavior on how and when to navigate
• Inversion of Control through Dependency Injection and Property Injection
• Plugin framework, which lets you plug-in cool stuff like GPS Location, Localization, Sensors, Binding Extensions and a huge selection of 3rd party community plug-ins

MvvmCross is extendable by you. We strive to let as much code be configurable and overridable, to let the developer decide how they want to use the framework. However, the framework is very usable without doing anything.

MvxSidePanelsPresenter bug - IOS

I am using the latest Xamarin version and MvvmCross 4.3.0

The problems occurs when I navigate from screen to screen randomly. Let's say I have an home screen and from there I go to UIViewController A then I go back to Home, then I go to UIViewController B and then back to home again, then I go to UIViewController A again and then back to home again, after I go to B again it sometimes breaks...

As an actual behavior it somehow mixed the view models and because the outlets are not there it just breaks and crashes.

Configuration

Version: 4.3

Platform: iOS

Stacktrace:

Unable to cast object of type 'GoWorky.Mobile.iOS.Employer.ChooseManagerViewController' (Objective-C type: 'ChooseLocationViewController') to type 'GoWorky.Mobile.iOS.Employer.ChooseLocationViewController'.

The idea is that it has a confusion with the previous view controller I was besides Home - at some point it swaps UIViewController A with UIViewController B.

MvvmCross Ios Navigation bug

To help us fix your issue, please provide the information in the below template.

Note: There is often little we can do without a minimal reproducible sample of the issue, so please provide that in a standalone git repository and link it here.

https://github.com/slown1/IosNavigationBug

Please only file bugs verified on latest version of MvvmCross and stable Xamarin tools
I am on the stable channel and I am up to date.

Steps to reproduce

After you login go from the menu to the Notifications, then Shift Templates, then History and repeat these steps until it breaks.
The exception is caught in

You can run the application in the simulator with the Developer Automatic settings.
I have noticed that in the simulator it reproduces harder and it also has another crash which seems like a leek. Can you also help here?

1. http://www.screencast.com/t/3tZnZIvXDAf

Expected behavior

It should not crash

Actual behavior

It crashes with exceptions which are like this:

"Hamburger" icon disappears

Can be reproduced in current MvvmCross-iOSSupport.Samples (commit c56c97f).

Steps to reproduce

1. Run MvvmCross-iOSSupport.Samples with MvvmCross.iOS.Support.Sidebar as startup project
2. Tap on Hamburger icon, notice that sidebar opens and Hamburger icon remains visible
3. Tap on Example Menu Item in sidebar, notice that Hamburger icon disappears

Expected behavior

Hamburger icon should always be visible

Actual behavior

Hamburger icon disappears after tapping on first menu element

Configuration

Version: 4.2.3

Platform: iOS

NOTE: calling ShowMenu for every newly-opened screen does make the Hamburger icon reappear, but it isn't a viable solution because it creates a new instance of the menu

Allow user to use own hamburger icon

https://github.com/MvvmCross/MvvmCross-iOSSupport/blob/master/MvvmCross.iOS.Support.XamarinSidebar/Hints/MvxSidebarActivePanelPresentationHint.cs#L49

This needs to be configurable

Tab presentation: impossible to have dynamic tab title

710b4b5

After this commit, title and icon can only be set with the MvxTabPresentation annotation:

[MvxTabPresentation(MvxTabPresentationMode.Tab, "Tab 2", "ic_tabbar_menu", true)]

However, for annotations you can only use constant values. Hence, the possibility for a dynamic tab title (for example for localization) is impossible.

This used to be possible using the presentationBundle:

ShowViewModel<Tab2ViewModel>(presentationBundle: new MvxBundle(new Dictionary<string, string> { { "icon_name", "ic_tabbar_menu" }, { "title", "Tab 2" } }));

Fix samples for MvxTabsPresenter so they work without provisioning profiles

As mentioned in #36 (comment) something is wrong with the build settings for the sample, so it won't run on Sim without having provisioning profiles.

Needs fixing.

Create Demo Using MvxExpandableTableViewSource

Currently the sample applications do not make use of the MvxExpandableTableViewSource in order to demonstrate its use and functionality. This should be added in a future version of the library.

CSProj file errors

I downloaded the MvvmCross-iOSSupport repro to have a look at the new stuff. There are a couple of small issues with the CSPROJ

The MvvmCross.iOS.Support project has a SidePanels folder.

1. The IMvxToggleMenu.cs is in the CsProj files but not on disk. I assume it is old
2. The File IMvbxSideMenu.cs is in source download but not included in the CSPROJ

JASidePanels vs XamarinSideBar

I'm wondering which are the differences between these two components...
Becase I'm not sure about which one I should choose for a project of mine.

This is my basic understanding:

• the JASidePanels component is distribuited by Xamarin
  https://components.xamarin.com/view/jasidepanels
  which is just a binding library around the native library:
  https://github.com/gotosleep/JASidePanels
  Both the native version and the Binding Library of JASidePanels component don't get new updates since long time.
• the XamarinSideBar is a c# component and can be found here:
  https://github.com/jdehlin/Xamarin-Sidebar
  And seems to receive some contribution once in a while.

Are these statement correct?
Moreover, do exists any relevant differences in the features provided by these components?

MvxTabsPresenter: Set title and icon for tabs using MvxTabPresentationAttribute

The current implementation of MvxTabsPresenter forces the user to use hard-coded strings to set each tab's title and icon through presentationValues parameter of ShowViewModelmethod.

Both attributes should be set when defining that a view will be presented as a tab.

I'll PR this in a few seconds.

Debug file embedded in final NuGet packages

Looks like MvvmCross.iOS.Support.nuspec is embedding some temporary *.cs files in the final package currently distributed on NuGet. The package contains the lib\Xamarin.iOS10\obj with 3 TemporaryGeneratedFile_*.cs file in each Debug and Release.

The problem seems to come from this line of code but I am not filling confident to PR on this as I currently do not understand why it is there in the first place (no nuget background, sorry).

Accordion ExpandableTableView support

ExpandableTableView should support "Accordion Expand" - that means:
at same time only one item can be expanded/collapsed.

Tapping on menu items on Right side bar is not working

Steps to reproduce

1. Download sample app from https://github.com/MarcBruins/MvvmCross-Sidebar-Sample which uses the libraries
2. On Menu view make panel to Right side
3. Launch the app and swipe from right
4. Tap on menu item
5. Not able tap.

Expected behavior

Able to Tap on right side bar menu items

Actual behavior

Not able to tap on right side bar menu items

Configuration

Platform: iOS

Info on issue:
Seems be in class MvxSidebarPanelController and if interchange right and left side bar, i can able to tap.

LeftSidebarController = new SidebarController(_subRootViewController, NavigationController, initialEmptySideMenu);
RightSidebarController = new SidebarController(this, _subRootViewController, initialEmptySideMenu);

ExpandableTableView should have protected methods/events like Expanded/Collapsed

Like in title.
This is needed so some fancy animations like expand arrow rotation can be implemented.

XamarinSidebar implementation always showing 'Menu' buttons

The current (version 4.4.0) implementation of the Xamarin Sidebar component always shows a "Menu" link button on the left and right side of the navigation bar, even when no left or right menu implementations are provided.

I am currently working on a fix.

MvxExpandableTableViewSource: GetViewForHeader multiple buttons added

In the MvxExpandableTableViewSource:
link

In the GetViewForHeader method, there is a new button added to the header every time the method is called.

As the header is obtained through the GetOrCreateHeaderCellFor method, the cell may have already been created and is being reused. Therefore you will have multiple buttons added to the same header, all calling the EventHandler method with different section's.

XamarinSidebar: When no menu is defined, the right side menu can still be opened with pan gesture

As the title says, when no menu is displayed (no ShowViewModel<>() call for any of the menus) the right menu can still be opened with a pan gesture and a black view is displayed.

Maybe the presenter is intented to always display a side panel, but there are some cases (like a login screen) where no menu is required.

Steps to reproduce

1. Open iOS-Support solution and set MvvmCross.iOS.Support.XamarinSidebarSample.iOS as startup project.

2. Comment this and this lines

3. Run sample

Expected behavior

The right panel shouldn't be opened when performing a pan gesture.

Actual behavior

The right panel is opened when performing a pan gesture.
