Get contents of a specific folder in documents diectory - ios

Question

Im trying to read contents of a specific folder in documents directory thats contains only png's /Documents/ApplianceImagesFolder/
Currently I can only get all my images from documents folder, how can I target contents of ApplianceImagesFolder only?
//gets all png form documents folder
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsPath error:nil];
fileList=[[NSMutableArray alloc]init];
for (NSString *dir in dirContents) {
if ([dir hasSuffix:#".png"]) {
NSRange range = [dir rangeOfString:#"."];
NSString *name = [dir substringToIndex:range.location];
if (![name isEqualToString:#""]) {
[fileList addObject:name];
}
}
}
NSLog(#"document folder content list %# ",fileList);

Answer 1

Build the desired path:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSString *folderPath = [documentsPath stringByAppendingPathComponent:#"ApplianceImagesFolder"];
NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:folderPath error:nil];
And there's a better way to find the png files:
fileList=[[NSMutableArray alloc]init];
for (NSString *filename in dirContents) {
NSString *fileExt = [filename pathExtension];
if ([fileExt isEqualToString:#"png"]) {
[fileList addObject:filename];
}
}
NSLog(#"document folder content list %# ",fileList);
