Deep Dive into the two Quick Start Apps

Picked up some things from the Deep Dive of the first App, Phoneword_iOS(single screen):

  • The basic structure of the whole solution: Solution > Project1, Project2, - - -
  • In a project, there are some files such as Main.cs, Main.storyboard, AppDelegates.cs ViewController.cs etc.
  • The basic architecture: Main - AppDelegate - View
  • UI keywords: View/Subview, Content View Hierarchy, ViewController etc.
  • Subviews have some properties, and they are defined in Properties Pad and Document Online Pad.
  • Segue shown as a gray arrow in storyboards represents screen transition.
  • View Life Cycle: ViewDidLoad starts the cycle. ViewWillAppear/Disappear, ViewDidAppear/Disappear are also useful in some Apps.
  • Some Events such as TouchUpInside are called in this App, and the events seem to be defined in UIKit class.
  • Some control methods for Button: how to change button name, how to enable/disable button.
  • How to dismiss keyboard on simulator after text input (ResignFirstResponder()).
  • How to set Breakpoints for debug.
  • Device Provisioning seems to enable real device test.
  • Mac's App, Sketch, seems to be helpful to create icon images.

  • The basic architecture to pass data to other screen: Model - View - Controller
  • NavigationController manages navigation between multiple screens. TabBarController and SplitViewController are also useful in some Apps.
  • It's possible to pass data between screens without Segue. The methods enable to handle more complex navigation, conditional navigation for example.

Command Prompt (1)

イメージ
I have been fighting with programming to develop an App I want to use, but this Command Prompt App will not be directory useful for the App. This is just a Xamarin.Forms programming training for me. I wanted to more learn ScrollView which behavior is a little bit confusing, and also to find a smart style to monitor some variables and App's behaviors while running App, so I came up with an idea to develop Command-Prompt-like-UI App looking like Unix or MS-DOS console. Including PCL Storage will make possible file and directory I/O, but it will be in other post. In this post, just a development of a Command-Prompt-Like-UI is explained. MainPage.xaml <? xml  version = " 1.0 "  encoding = " utf-8 "   ?> < ContentPage   xmlns = " http://xamarin.com/schemas/2014/forms "               xmlns : x = " http://schemas.microsoft.com/winfx/2009/xaml "         ...

ListView (2)

Having studied the basic function of the ListView control in the previous post,  ListView (1) , a variable "books" was declared as a list of book titles. But book information includes some attributes, author, date of issue etc., as well as title. So it seems to be good that book information is declared as a Class as below. Book Class public class Book {      public string Title { get; set; }      public string Author { get; set; } } The following sample code displays the ListView of book information declared as class type above. MainPage.xaml <? xml  version = " 1.0 "  encoding = " utf-8 "   ?> < ContentPage   xmlns = " http://xamarin.com/schemas/2014/forms "               xmlns : x = " http://schemas.microsoft.com/winfx/2009/xaml "               xmlns : local =...

ListView (1)

I have studied the overview of Xamarin.Forms through the Quick Start in Xamarin official site, so I have started to study C# and XAML more deeply with ListView control as an example. I wrote a small program referring to  ListView guides  in Xamarin official site etc. MainPage.xaml <? xml  version = " 1.0 "  encoding = " UTF-8 " ?> < ContentPage   xmlns = " http://xamarin.com/schemas/2014/forms "                xmlns : x = " http://schemas.microsoft.com/winfx/2009/xaml "                x : Class = " ListView.MainPage " >          < ContentPage.Content >          < StackLayout >              <!--  Add a new book to the b...
