Ho creato uno script Python per identificare le immagini inutilizzate: 'unused_assets.py' @ gist . Può essere usato in questo modo:
python3 unused_assets.py '/Users/DevK/MyProject' '/Users/DevK/MyProject/MyProject/Assets/Assets.xcassets'
Ecco alcune regole per utilizzare lo script:
- È importante passare il percorso della cartella del progetto come primo argomento, il percorso della cartella delle risorse come secondo argomento
- Si presume che tutte le immagini siano conservate nella cartella Assets.xcassets e siano utilizzate all'interno di file swift o all'interno di storyboard
Limitazioni nella prima versione:
- Non funziona per i file c oggettivi
Cercherò di migliorarlo nel tempo, in base al feedback, tuttavia la prima versione dovrebbe essere buona per la maggior parte.
Di seguito trovi il codice. Il codice dovrebbe essere autoesplicativo poiché ho aggiunto commenti appropriati a ogni passaggio importante .
# 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
