StoryBoard launch screen - Delphi 10.4

Recommended Posts

Is anyone managing to use the storyboard launch screen? Here it is only working with the original delphi color and image. When I try to change the background color or the image in the project options, it has no effect.

I found the problem and this is not a delphi bug. The problem is with the iOS cache, the app don't update new launchscreen / icon, even you uninstall and install your app. The solution is:

 

1) Uninstall the app

2) Power down the device

3) Power up the device

4) Install the app

Renaming the app has the same effect. Certainly saves on having to restart the device 🙂

Hi Guyz

 

I'm having an issue making the storyboard work with an existing app (I haven't tried with new apps yet).

 

I've followed these steps but I keep on getting a blank screen:

 

1.) I deleted the info.plist.TemplateiOS.xml from my project directory.

2.) Added the launch images in the project options

3.) I edited the LaunchScreen.storyboard and Assets files in LaunchScreen.TemplateiOS (actually only the Contents.json file in the Assets\LaunchScreenImage.imageset folder) as needed by replacing the default FM launch icons with mine.

4.) Made sure that my launch screen images to be deployed are in the "Project | Deployment".

5.) Deleted the app on the device (as @vfbb suggested above)

6.) Powered down the device (as @vfbb suggested above)

7.) Powered up the device (as @vfbb suggested above)

8.) Installed the app (as @vfbb suggested above)

 

Any ideas

The options of the delphi 10.4 is working perfectly for this, you don't have to add it manually to the deploy project and you don't need to change the storyboard files either. You can test with a new project.

Hi @vfbb. Option 4 yes. Option 3 isn't working. The default Delphi launch screen images are added no matter what.

No, it is correct. The name in that file is not the name your image in your computer, but the name of the image in the remote device.

As I told you, just delete your app, restart your phone, open a blank project, change it by options and compile and you will see that is working.

unistalling the app and restarting the iOS device is not working for me.

 

This seems an Embarcadero bug

More news:

 

I sent an ipa file to TestFlight, and when it was available I installed it in my iPad.

 

Aafter removing previous version, rebooting , and installing from TestFlight, still with no splash screen.

 

So probably my final version will be rejected. 😞

It's not, e.g:

Another possible solution (which I have not tried):

Edit: An afterthought - this might not help you since your problem is no splash screen at all. Having said that, I still expect it is not an Embarcadero issue.

I still have a blank screen. Let me show you my resolutions, may be this is the problem:

 

Iphone 2x: 750x1134

 

Iphone 3x:  1125x2436

 

iPad 2x:  1536x2048

 

All portrait, because the App only works in portrait

I have some issues from time to time, with the LauchScreen, but not only the image.

Sine this is maybe all related, I think this could be added in the thread too

 

1. In one app I have a too small launchscreen icon.
    The base icon is same size, but it appears only 1/3 of the size on its screen.
    Have tried to reset settings, re-create project, etc., clear the storybook, change the colors, etc. but it stays the same.
    While other projects icon looks OK, stretching to fit the whole display,
    I cannot really see any difference.

    (but since this behaviour was acceptable, I haven't looked into it much deeper).

2. A newer, and not acceptable behaviour is the white background when an app goes background and foreground again,
    it starts with a white background screen, until "BecameActive", only then I can reset the screen again.
    Its not showing the LaunchScreen then, but the current display, and this is "white" instead of normal color.

    To get a better impression, on the fron page there is a TListView:

    This is how it should look (and it does when first starts)
    image.png.cf70e5330da030f5588ca5bd829de929.png

    This is how it looks when background/foreground, until "BecameActive", only after BecameActive I can reset,
    but thats a well visible flicker when starting.
    image.png.d9154f2de5d567507b656e7764e8b85f.png

 

It looks to me that the style or the listview is somewhat affected by background foreground change,
since I cannot find any other reason for setting the colors like that.
I do use the StyleManager, and setting the style once at startup, usually no need to reset again when BG/FG.

What I tried is to set the background colors in many ways, also to force a change,
but I want to put them "black" in light and dark themes, like that:
image.png.bb87ab9c2e7cd23332b39f79a7a7170f.png

 

I think this was a similar issue here.


When I change the colors, Apple seems to require the colors as float (0.0 ... 1.0),
but in the .storyboard template I can see a white background (color 1 1 1 1)

    <resources>
        <image name="LaunchScreenImage" width="96" height="96"/>
        <namedColor name="LaunchScreenBackgroundColor">
            <color red="1" green="1" blue="1" alpha="1" colorSpace="custom" customColorSpace="sRGB"/>
        </namedColor>
    </resources>

In the compiled storyboard, this is still the same
 

    <resources>
        <image name="LaunchScreenImage" width="96" height="96"/>
        <namedColor name="LaunchScreenBackgroundColor">
            <color red="1" green="1" blue="1" alpha="1" colorSpace="custom" customColorSpace="sRGB"/>
        </namedColor>
    </resources>

But additionally, there were LaunchScreenBackgroundColor.colorset definitions, looks as HEX instead of 0...1

{
  "colors" : [
    {
      "idiom" : "universal",
      "color" : {
        "color-space" : "srgb",
        "components" : {
          "alpha" : "255",  //<=========================== HEX instead of float
          "blue" : "0",
          "green" : "0",
          "red" : "0"
        }
      }
    },
    {
      "idiom" : "universal",
      "color" : {
        "color-space" : "srgb",
        "components" : {
          "alpha" : "255",    //<=========================== HEX instead of float
          "blue" : "0",
          "green" : "0",
          "red" : "0"
        }
      },
      "appearances" : [
        {
          "appearance" : "luminosity",
          "value" : "dark"
        }
      ]
    }
  ],
  "info" : {
    "version" : 1,
    "author" : "RAD Studio"
  }
}

That looks like an issue with the RadStudio conversion of those flags HEX instead of float ,
but even when I handcode the .storyboard files, I cannot really see a difference (maybe because of caching).
I try to investigate this further.

 

Maybe the launchimage,  the too small icon 1.) and this color issue 2.) were all related somehow, but I cannot really spot the root cause.

I hope you can spot the issue here, and has some useful hints.

When I try to set different colors in the IDE, this can be used to set "fake" colors, at least for black color.
This should be right to set black background color.

 

Like that:
image.png.779760886c13b82d6919aaab6fe5066b.png


results in "float-like" output:

{
  "colors" : [
    {
      "idiom" : "universal",
      "color" : {
        "color-space" : "srgb",
        "components" : {
          "alpha" : "1",
          "blue" : "0",
          "green" : "0",
          "red" : "0"
        }
      }
    },
    {
      "idiom" : "universal",
      "color" : {
        "color-space" : "srgb",
        "components" : {
          "alpha" : "1",
          "blue" : "0",
          "green" : "0",
          "red" : "0"
        }
      },
      "appearances" : [
        {
          "appearance" : "luminosity",
          "value" : "dark"
        }
      ]
    }
  ],
  "info" : {
    "version" : 1,
    "author" : "RAD Studio"
  }
}

Anyway, the issue with white background while BG/FG is still the same.

I assume it has something to do with Styles and TListView, not the storyboard colors.
