Ich habe ein Python-Skript erstellt, um die nicht verwendeten Bilder zu identifizieren: 'unused_assets.py' @ gist . Es kann folgendermaßen verwendet werden:
python3 unused_assets.py '/Users/DevK/MyProject' '/Users/DevK/MyProject/MyProject/Assets/Assets.xcassets'
Hier sind einige Regeln für die Verwendung des Skripts:
- Es ist wichtig, den Pfad des Projektordners als erstes Argument und den Pfad des Assets-Ordners als zweites Argument zu übergeben
- Es wird davon ausgegangen, dass alle Bilder im Ordner Assets.xcassets verwaltet werden und entweder in schnellen Dateien oder in Storyboards verwendet werden
Einschränkungen in der ersten Version:
- Funktioniert nicht für objektive c-Dateien
Ich werde versuchen, es im Laufe der Zeit zu verbessern, basierend auf dem Feedback, aber die erste Version sollte für die meisten gut sein.
Nachfolgend finden Sie den Code. Der Code sollte selbsterklärend sein, da ich jedem wichtigen Schritt entsprechende Kommentare hinzugefügt habe .
# Usage e.g.: python3 unused_assets.py '/Users/DevK/MyProject' '/Users/DevK/MyProject/MyProject/Assets/Assets.xcassets'
# It is important to pass project folder path as first argument, assets folder path as second argument
# It is assumed that all the images are maintained within Assets.xcassets folder and are used either within swift files or within storyboards
