I'm looking to create a grid of icons from which one can be selected (see the Daytum app for an example of this).
Are there any existing form entry frameworks for iOS that already support this (eg QuickDialog is excellent, but doesn't support this)
What would be the best way to implement this? Assuming selecting an icon brings the user back to a form field with the icon populated in the field.
Are there any other apps apart from Daytum that use this 'model?
Three20 has a grid view controller, that makes it pretty easy to add icons in a grid.
I'm a huge fan of AQGridView. Used it in a couple of projects and i think its really really built well and easy to implement.

I have a screen with 1 button. When clicking that button, a list of items should be shown (in which the user can select multiple items).
On android, i would like to do this using a dialog. I create a "DialogService" that does this, no problem.
On iOS, however, it seems that the best practice is to display a fullscreen tableview, for example as a modalView. Is it possible to do this without using a custom viewpresenter (e.g. modalViewPresenter)? I would very much prefer to have identical navigation on both platforms and just have different implementations of "DialogService"
I think trying to make one platform look and act like another is generally not a great idea as things start to look weird for the users.
But if you want to do it anyway I would start by trying to do something like this https://stackoverflow.com/a/29910246/1107580 (it is in objective-c) then trying to bind to the tableview that is in the alertcontroller.
I am going to implement Alert feature in my application.
When user taps an alert button my application is about to change all orange (default) colors to red (Navigation bar, switches, Tab bar, Buttons, views and other stuff).
I want to implement it using "css" files also known as stylesheets.
I've found two libraries: Motif and NUI.
The most important problem is to dynamically change theme inside application. Motif can do this but I want to do it more simple.
Also I learned that NUI can change the app theme too but I can't to change it dynamically.
P.S. I am using storyboard and XIB-files. I need to add runtime attribute for object's key-path. This attribute will go to my stylesheet file and apply styles. It's the most simple way I think.
Can I do it simply and without any libraries?
P.S.S. NUI is more simple for me. Maybe you know how to change styles when application runs.
There are ways of making this work, but not very simply. So your options are either to construct your own solution, or use a library.
If you are looking for something that feels easier and more native than NUI or Motif, and which also lets you assign styles and see them rendered live inside your storyboards, take a look at my library for this: https://github.com/daniel-hall/Stylish
Here is a demonstration of changing the "stylesheet" (which can be created either in code, or in an external JSON file) at runtime:
I am using Picker for displaying the items,I want to select multiple rows in picker, is there any way to achieve this in Xamarin Forms shared code or through rendering? any suggestion or idea would be much appreciated.
Thanks.
I don't would use Picker for multilselection.
You can do this with a ListView (100% XF-Code).
I have posted some code some time ago in the XF-forum:
http://forums.xamarin.com/discussion/17885/multiselect-listviews
If you have to show the "Multiselect-ListView" from a ScrollView, you may also be interested to use the PopUp-Control (XLabs):
https://forums.xamarin.com/discussion/33587/how-to-use-a-listview-in-a-scrollview-with-xlabs-popup-control#latest
And finally, if you want to install the XLabs-NuGet, a further posting to XLabs may help you (search for "How to install, setup and use XLabs" in the XF-forum).
As i don't have more than 10 rep-points here, I am not able to post more then two links :-)
Hope this helps...
No there isn't.
The Picker Class, has SelectedIndex property, but no SelectedItems collection. Also, the native control under the hood on iOS doesn't support selecting multiple rows and I don't think the Android or Windows one do either.
You could create use a Custom Renderer if there was a native control you wanted to use. But, it would probably be easier to use a ListView control and add some events and style it to look and behave like you want.
How do I create a tab bar like WhatsApp on BlackBerry in my BlackBerry app? I want that feature in BlackBerry OS 7.0. I have used managers -- HorizontalFieldManager and VerticalFieldManager -- to achieve it. But it doesn't look as attractive as WhatsApp. Can FieldTabController help me do this?
It's not going to look attractive if you are just making tweaks to the code, and then seeing what that looks like. You need to start with a design you find attractive. Once you have that goal put together as an image, you start writing code to make the UI look like the design image.
The WhatsApp tab bar is not a straightforward combination of built-in UI managers from RIM. It has a fair amount of customization - each tab has three visual states, and there is a tooltip that follows the focus, as well as a context tab on the right that changes depending on the currently selected main tab. This means there are several interacting UI components here, not just a single magic manager.
Essentially, you will probably want to start building your own custom Field objects.
Basically, subclass the Field class (or one of the other subclasses), and learn to love the paint(..) method and the Graphics API.
I'm in the process of developing an iPad-only survey-app using MonoTouch. With monotouch.dialog (mt.d) I found that building these interfaces can come quickly, which is awesome.
However... I also found that mt.d only does about 80% of what I want. Makes me wonder: should I invest in extending mt.d to my needs or should I choose something differently over mt.d?
Some of my requirements:
Radiogroups without transitions: I like the options to be
presented right away (there's more than enough space on the iPad
screen)
A rating UI control, such as
http://www.cocoacontrols.com/platforms/ios/controls/dyrateview
Mixed radiogroups: like 3 predefined elements and a fourth which
allows for manually added content
What are your thoughts on this? Can this be done easily (I'm a trained programmer, but quite new to both C# and iOS development)? Do you guys know of any online repositories of custom UI components with C#/MonoTouch bindings?
Thanks a lot!
This is of course a subjective opinion, but my take on it is that if you believe you can do your UI in UITableView (which MonoTouch.Dialog is based on), then you should go for MonoTouch.Dialog. If UITableView will not fit your needs, you should look for a different approach. MonoTouch.Dialog is quite flexible, and open-source, so if you need anything to be different you can just use the source code and modify it at will.
