I am updating the icons in my app. After I heard Apple released an icon font named SF Symbols with iOS 13, I was wondering if I can only use them in iOS 13 or if it is possible to use them in lower versions of iOS too.
If I want to use them, do I have to implement a fallback for older versions?
You can not use SFSymbols natively in iOS versions older than iOS 13 (see Apple's Human Interface Guidelines for SF Symbols).
However, if you are interested in using the graphics you can use the SF Symbols app to export SVG versions of the icon. Then use some graphics tool to convert them to PNG icons you can import into your asset catalog.
You can open .svg use Figma. Then select the Regular-M and export as PDF or PNG.
Update for more details:
You can use the PDF vector assets in Xcode. So that the icon should fit any size you want. Please check this blog: https://useyourloaf.com/blog/xcode-9-vector-images/
The new Xcode has a different UI but basically the same. In the Assets Catalog:
Drag your PDF vector file in.
Check "Preserve Vector Data"
Choose "Single Scale"
Work around in progress
I did not manage to find the solution, I gave up, but actually I went pretty far in investigating. Maybe someone luckier than me will be able to figure out hpw to continue the work I started:
In Apple documentation, it is said that, in order to easily browse all the new iOS 13 SF Symbols, you can dowmload the SF Symbols app : https://developer.apple.com/design/human-interface-guidelines/sf-symbols/overview/
Once instaled you can go in Application > SF Symbols > showPackage content
From there, under content > Resources we can find an interesting file named SFSymbolsFallback.ttf
And if you try to open this file on https://fontdrop.info/ you can see that it contains all the font glyphs that are released in iOS 13 as SF Font, with associated unicodes
Bingo? not so fast...
From there I tried to import this .ttf into my project in iOS 12, on XCode 10.2.1, but it seems that it is never properly imported. It is not retrievable in the list of available fonts when calling UIFont.familyNames
More interesting, if I try to import this font in Font Book app, I receive a warning that says that it contains duplication, some kind of conflict with an existing font
From there?
My guess is that there is another font that prevent SF Symbols to be installed, in Font Book and on Xcode.
One of the solution could be to find the one that is in conflict in XCode package and delete it ( this may be Symbols font or San Francisco that are causing problems idk)
I also tried to open the font file with a font editor and change its Name and family Name without success.
If anyone want to continue investigating..
Hope this can help someone !
This icon set is based on SF Symbols https://framework7.io/icons/
You can upload the new ios 13 sf-pro-rounded font to your project. Then enable that font in your label.
Open sf symbols, click on the smbol you want, cmd+c, go to your project, click on a label cmd+v. Run the project, and there should be the icon
cheers,
In SF Symbols 3.1, Edit > Copy Image as...
You can choose PNG/point size/pixel scale and paste into Preview etc.
SF Symbols is a system only supported on iOS 13 or later - it's not possible to use them on iOS 12 or below. You'll need to use fallbacks for those older operating systems.
See Human Interface Guidelines
1. Import the font:
Open the Fonts app, search for the SF Pro Rounded font, right-click on the variant you want (e.g. Light) and click Show in Finder. Drag that file (e.g. SF-Pro-Rounded-Light.otf) into your XCode project and tick "Copy if necessary".
2. Select the font:
Select your UILabel or UIButton, set the Title to Attributed (this is important) and select the font you just copied (e.g. SF Pro Rounded Light).
3. Set the symbol:
Find the icon you want in SF Symbols, select it, press CMD+C to copy, switch back to XCode and click in the text part of the UILabel or UIButton Title and press CMD+V to paste.
A huge thank you to Dave van Wijk for the solution!
I am using Delphi 10.3 Community Edition and I'm on Windows 7.
By default the buttons generated by Delphi are (of course) Win7 style.
How can I have "old-style" Win98 buttons (see attached picture).
Thanks.
Uncheck the enable runtime themes option.
I Upgraded from C++ Builder XE7 to C++ Builder Berlin and I have a project with about 100 images in 6 ImageList controls.
In XE7 the transparency worked fine, but after the upgrade all images now have a black solid background instead of transparency.
I double checked that the ImageList's ColorDepth still was cd32bit, and it is. Everything looks file in the IDE, images are transparent, but as soon I run my application, all images have a black background instead of transparency.
I tried to drop a new TImageList, cd32bit depth and added some transparent PNG:s that worked fine in XE7. Still they show up with a black background in Runtime, but not in the IDE.
Finally figured it out!
I noted that all controls had the old Win XP style so I suspected that the wrong version of Comctl32.dll was loaded, the question was only how to change it?
The project is very old and was created before C++ Builder supported manifests. But in the project options, under Application you will find a section named "Manifest File".
Set it to "Auto Generate" and tick the checkbox "Enable Runtime Themes" and it will use the correct version of Comctl32.dll
I see from an online search how to change the font size for the environment, but when I run programs, the font size for the program is still tiny. How do I change that font size? Thanks!
Right click on the top of the window and choose 'Defaults', edit the size settings, save and load the command window again

In my app I need to support iOS since iOS 7. As you know iOS 9 uses new system font "San-Francisco".
Is it possible some how to use system font (to make native font for operation system) with setting size and attributes like Light, Medium, Bold, Italic, etc?
I found only one solution to hard code font name as for iOS 9 use "San-Francisco" and for less use "HelveticaNueue".
Maybe some one know a better solution.
