Programmatically access image assets

Question

My image assets catalog has a folder named \"Nature\" with hundreds of image files inside.

I would like to get an array of image file names under the \"Nature\" dire

Answer 1

this may be late but this might helps others

you can not directly access all the file from assets as its compiled to .car

alternative to access the all files from the assets is to create the .plist file with the all images that assets contains and plist file can be easily accessible. following are the steps to achieve this

Step 1: add script in Build Phases -> Run Script

echo "


" >  ${SRCROOT}/${PROJECT_NAME}/files.plist;
## Chnage Assets.xcassets if not using default one
find ${SRCROOT}/${PROJECT_NAME}/Assets.xcassets -type f -not -iname "*@*" -name "*.png"  -exec basename {} \; | while read line; do echo \$line\\$line\; done >> ${SRCROOT}/${PROJECT_NAME}/files.plist;
echo "" >>  ${SRCROOT}/${PROJECT_NAME}/files.plist;

this script generate files.plist in project directory with all images in assets file add this file to project

Step2: Accessing plist file

NSURL *filepath = [[NSBundle mainBundle] URLForResource:@"files" withExtension:@"plist"];
NSMutableDictionary *allXCAssetsImages = [NSMutableDictionary dictionaryWithContentsOfFile:filepath.path];
