Trying to see xamarin.Forms and ReactiveUI playing nicely together and I run into the following error when trying to bind to a xamarin.form button
Couldn't find a Command Binder for Xamarin.Forms.Button
using this code:
this.BindCommand (ViewModel, vm => vm.Register, v => v.register);
Am I missing something or do I need to do some special binding for these new xamarin.forms controls?
It works, but support is brand new - you need to build ReactiveUI from source at the moment and include the new ReactiveUI.XamForms.dll assembly.

basically I have some Objective-c class already existing and I want to use them in my NativeScript projet. Currently I have added those files to the Xcode project target and I want to be able to call my objective-c code from nativeScript js. I've read the doc but I don't understand it. It seems so complicated. basically currently all I want to do is be able to present my custom view controller by calling probably something along
const vc = MyCustomViewController.alloc.initWithNibName("xib file")
page.frame.ios.controller.present(vc,true, nil)
Am I obligated to create a plugin for that? Am I obligated to use my objective-c class to build a framework in Xcode and then import the framework?
So I found out.
Actually what you need to do is first to compile your native iOS code into a framework. As per the documentation all your classes must inherit NSObject and all your function must be marked with #objc to be exposed to the objective-c Nativescript side if you write in swift. You will notice as well that in a framework your bundle is not the main bundle. In this example you can see how you can retrieve the bundle from the framework and load a xib from it.
Then you need to add your framework file to a Nativescript plugin. For that, you want to add the framework to the plugin's iOS folder yourPlugin/platform/iOS/yourFramework.framework.
then, you need to add your plugin to your app. You can add your local plugin by using the next command line. Notice the path end with the /src folder.
tns plugin add /path/to/yourplugin/src
Now, you can then call your native functions and classes without even importing them. Of course this works only on iOS. If you run your app on android, calling those methods will crash.
To show this viewController on your Nativescript side you will need to call the following code. By the way You can find documentation elsewhere to get a reference to the current page or frame object.
const controller = page.frame.ios.controller
const vc = IOMediaViewController.create()
vc.modalPresentationStyle = UIModalPresentationFullScreen
controller.presentViewControllerAnimatedCompletion(vc,true,null)
I am currently developing a Xamarin.Forms application. I am using IconizePlugin. The app is tabbedPage based and on toolbar I'm trying to include icons for some actions.
This is whay I'm getting:
Icons are showing well and in Xamarin.iOS gets the click event, while it is not working in Xamarin.Droid.
I included the corresponding nugets and followed every steps told in documentation and can't archive this. Other iconize controls in Droid are working fine except the IconToolbarItem.
Please help!
The workaround I found was to declare de IconToolbarItem in the c# code instead of xaml. Although I don't know why it wasn't working while on xaml.
Declaring the item li
ToolbarItems.Add(new IconToolbarItem
{
Icon = "fa-plus",
IconColor = Color.White,
Command = new Command(this.addBono)
});
I am writing a Xamarin Forms PCL application (both iOS and Android)
I have to pick an image from phone gallery.
I have read some documentation about this plugin:
Labs.Platform.Services.Media.MediaPicker
In my Common project, i have to put this code:
var device = Resolver.Resolve<IDevice>();
picker = DependencyService.Get<IMediaPicker>() ?? device.MediaPicker;
But I have an error on the first line: IDevice and Resolver Objects are not know. I think I am missing a reference or a using clause.
Thanks
You need to install the following Nuget package in all of your projects in the solution (i.e. PCL core project, iOS project, and the Android Project, and UWP project if using it):
https://www.nuget.org/packages/XLabs.Forms/
And you will need to add the following using statements:
using XLabs.Ioc;
using XLabs.Platform.Device;
using XLabs.Platform.Services.Media;
Hello Everyone I want to share the Text on Xamarin Form using Library plugin.share.

CrossShare.Current.Share("Hii alll", "Share");
please help me to get out of this,thanks in advance
You want to take a look at UIActivityViewController, you can find the documentation here https://developer.xamarin.com/api/type/MonoTouch.UIKit.UIActivityViewController/
And Xamarin.Forms specific example http://devcenter.wintellect.com/jwood/implementing-sharing-in-xamarin-forms
This is a bit old, but I was having a similar issue and was able to resolve it.
First of all, you need to add the plugin Plugin.Share to ALL Xamarin.Forms projects (Portable, iOS, Android, UWP).
In the class that references the share code, add...
using Plugin.Share;
using Plugin.Share.Abstractions;
CrossShare.Share() doesn't work with strings, directly. You need to new up a ShareMessage.
var title = "Title For The Share";
var message = "Text to share.";
await CrossShare.Current.Share(new ShareMessage { Text = message, Title = title });
I can't say specifically to iOS, as I don't have a Mac and can't test that project, but Android and Windows 10 is working.
I was trying to do Xamarin UI Test on existing application. When i added following AutomationId i can't run the application and it throws following error
Xamarin.Forms.Xaml.XamlParseException: Position 36:14. No Property of name AutomationId found
and i can't run the test either
Your Help will be really appreciated
AutomationId is supported since Xamarin.Forms 2.2.0 and replaces StyleId for UI testing purposes. So you have to update your package.
