Chat Calendar Message Styling

[Ilnam]

Hello,

Please add SfChatCalendarFontFamily element to set values to the in built keys of a calendar message in resource dictionary.

If I don't add the SF UI font to the app resource, the following warning keeps popping up.

"CoreText note: Client requested name ".SFUIDisplay-Medium", it will get TimesNewRomanPSMT rather than the intended font. All system UI font access should be through proper APIs such"

Thank you,

Ilnam

Hi IInam,

Thank you for your patience.

Your requirement can be achieved by setting the fontfamily for SfCalendar messages in Resources of SfChat. For more details please refer to the below Sample and code snippet.

Code snippet :

 

<ContentPage.Resources> 

        <ResourceDictionary> 

            <OnPlatform x:TypeArguments="x:String" x:Key="SfUIFont"> 

                <On Platform="Android" Value="SF-UI-Display-Medium.otf" /> 

                <On Platform="UWP" Value="/Assets/SF-UI-Display-Medium.otf#SF-UI" /> 

                <On Platform="iOS" Value="SF-UI-Display-Medium" /> 

            </OnPlatform> 

        </ResourceDictionary> 

    </ContentPage.Resources> 

     

    <ContentPage.BindingContext> 

        <local:GettingStartedViewModel x:Name="viewModel"/> 

    </ContentPage.BindingContext> 

 

     

    <ContentPage.Content> 

 

        <sfChat:SfChat x:Name="sfchat" 

                       Messages="{Binding Messages}" 

                       SendMessageCommand="{Binding SendMessage}" 

                       CurrentUser="{Binding CurrentUser}" > 

            <sfChat:SfChat.Resources> 

                <ResourceDictionary> 

                    <Style TargetType="sfcalendar:MonthViewSettings"> 

                        <Setter Property="HeaderFontFamily" Value="{StaticResource SfUIFont}"/> 

                        <Setter Property="DayCellFontFamily" Value="{StaticResource SfUIFont}"/> 

                        <Setter Property="DayHeaderFontFamily" Value="{StaticResource SfUIFont}"/> 

                    </Style> 

                </ResourceDictionary> 

            </sfChat:SfChat.Resources> 

        </sfChat:SfChat> 

    </ContentPage.Content>

The uploaded solution still seems to trigger the warning. In addition, it also causes an ArgumentNullException. 

I am having the same problem as the OP using just the SfCalendar.

My Console output from the code is as follows:

[Karthikraja Kalaimani]

HI Sam, 

 

Thank you for your patience 

 

Currently, we are checking in both SfChat and Calendar control to find root cause for the issue. We will validate both the source and update validation on January 8, 2021. We appreciate your patience until then.

Thank you - if it helps, my environment is as follows:

- Xamarin Forms 5 (although the problem occurred under previous v4.x versions too

- JetBrains Rider IDE 2020.3

- macOS 10.15.7

[Pradeep Kumar Balakrishnan]

Hi Sam, 

 

Thank you for the update. 

 

We have validated the faced issue “ArgumentNullException is raised when running the provided sample in form.ios platform” Adding ttf file name in info.Plist resolves this issue.  

 

Code Snippet: 

 

<key>UIAppFonts</key> 

       <array> 

              <string>SF-UI-Display-Medium.otf</string> 

       </array> 

 

But the following line is still written in output window with the above changes.  

 

“Client requested name ".SFUIDisplay-Medium", it will get TimesNewRomanPSMT rather than the intended font. All system UI font access should be through proper APIs such as CTFontCreateUIFontForLanguage() or +[UIFont systemFontOfSize:].”   

 

In our Sfcalendar source we have used UIFont.FromName method to define UI font value. Which is the root cause for this issue. we will update to SfCalendar team. They will update the timeline for the fix on or before January 13, 2021. We appreciate your patience until then.
