B4i (iOS) - Updates thread

[Erel]

will it be possible to publish apps that was made via b4i also to Mac App Store?

No. B4i will create iOS applications. Not Mac applications.

i know that we can make apps for Mac via b4j but can we also publish them on the Mac App Store too?

It should be possible to upload a B4J app to mac store. See this Oracle tutorial: http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/packagingAppsForMac.html

Now we have a Canvas object:

Supeeeer
now only a few objects and the first versione is ready.

 

[sorex]

nice job there Erel.

how much of the core libs are (partly) working already?

 

[Beja]

Great achievement.. congratulations with the first object..
I am camping right here!

 

[Erel]

A large part of the core library is already implemented.

If you like to see the core library progress you can check the attached xml file. It is the same format as B4A / B4J libraries so you should be able to browse it with one of the libraries browsers.
Note that it is not documented (and is of course not final).

Erel,
Do you think it is a good idea to open a forum for wishes to be included in the first version.

 

[Erel]

It is too early now for feature requests. Also remember that the first version is just the first version

As I see it the most important thing is to create a working version with the core features (in the world of iOS it is not a simple task at all) and release it. Many new versions will follow the first version and will add the requested features.

But IOS7 is a must?

 

[Erel]

Yes.

 

[migrec]

Now we finally can design some beautiful apps
thank you for this Erel

@wimpie3 :

90% of iOS users are on iOS 7, don't know how many of those are forced. ("Forced", meaning the FaceTime stuff.)

Is there going to be a way for us to create wrappers for libraries?
If the answer is yes, is it going to be neccesary to have a Mac to create the wrapper?

 

[Erel]

Is there going to be a way for us to create wrappers for libraries?

Yes. All the APIs are implemented as libraries.

If the answer is yes, is it going to be neccesary to have a Mac to create the wrapper?

Yes. Libraries are written in Objective C and must be compiled on a Mac.

 

[Beja]

One question
To install B4i, do we need to go through all the steps like b4a? installing SDKs of everybody and configure? or just
the b4i IDE is enough?

 

[Erel]

You cannot install iOS SDK on windows so its one less step. Java JDK is still required for the debugger.

You will need to follow several steps before you can run your first app related to the developer signatures.

Smiley example
Make sure to see it in HD.
The device in the right side is a real device mirrored with a nice tool named reflector. The app is first run in "no compilation" debug mode. In this mode remote compilation is not required (it is similar to the rapid debugger that was available in B4A before v3.50). The second time it is run in Release mode. In this mode you need to first install it through the device browser. I'm using a bookmark to make it easier. This is called over the air installation.


The code is simple:

Sub Process_Globals
   Public NavControl As NavigationController
   Private Page1 As Page
   Private panel1 As Panel
   Private cvs As Canvas
   Private timer1 As Timer
   Private bmp As Bitmap
   Private currentX, currentY, vx = 10, vy = 10 As Float
   Private smileySize As Float = 50
End Sub

Private Sub Application_Start (Nav As NavigationController)
   NavControl = Nav
   Page1.Initialize("Page1")
   Page1.Title = "Smiley Example"
   NavControl.ShowPage(Page1)
   panel1.Initialize("panel1")
   Page1.RootPanel.AddView(panel1, 0, 0, 100%x, 100%y)
   bmp.Initialize(File.DirAssets, "smiley.png")
   timer1.Initialize("timer1", 30)
   timer1.Enabled = True
End Sub

Private Sub Page1_Resize(Width As Int, Height As Int)
   CreateBackground
   panel1.SetLayoutAnimated(0, 0, 0, 100%x, 100%y)
   cvs.Release
   cvs.Initialize(panel1)
   cvs.DrawColor(Colors.Transparent)
   cvs.Refresh
End Sub

Sub CreateBackground
   'create the gradient background
   Dim c As Canvas
   c.Initialize(Page1.RootPanel)
   c.FillGradient(0, 0, 100%x, 100%y, Array(Colors.LightGray, Colors.DarkGray))
   c.Refresh
   c.Release
End Sub

Sub Panel1_Touch(Action As Int, X As Float, Y As Float)
   If Action = panel1.ACTION_DOWN Then
     cvs.DrawCircle(X, Y, 10, 0xAFFF0000, True, 0)
     If X >= currentX AND X <= currentX + smileySize AND Y >= currentY AND Y <= currentY + smileySize Then
       vx = -vx
       vy = -vy
     End If
     cvs.Refresh
   End If
End Sub

Sub Timer1_Tick
   Dim r As Rect
   r.Initialize(currentX, currentY, currentX + smileySize, currentY + smileySize)
   cvs.DrawRect(r, Colors.Transparent, True, 0)
   If currentX + smileySize > cvs.View.Width Then
     vx = -Abs(vx)
   Else If currentX < 0 Then
     vx = Abs(vx)
   End If
   If currentY + smileySize > cvs.View.Height Then
     vy = -Abs(vy)
   Else If currentY < 0 Then
     vy = Abs(vy)
   End If
   currentX = currentX + vx
   currentY = currentY + vy
   r.Initialize(currentX, currentY, currentX + smileySize, currentY + smileySize)
   cvs.DrawBitmap(bmp, r)
   cvs.Refresh
End Sub

great !! release a beta version so we can play with it a little bit..

 

[Peter Simpson]

Nice one @Erel,
Goodness knows where you find the time to do all this stuff. Keep up the great work...

Hi Erel

This is great news. What serial services will be available in the first/beta release. We have a product www.ursosbutton.com that we have developed and the device has a bluetooth chip to provide the serial i/o, will it be possible to communicate with b4i apps ?

Also will there some support for SQLlite ?

Regards

John.
