Answer 1

I hope you will have the file name in NSURL object, if so then you can use the following code to get just the file name and can remove the file extension from the string.

NSArray *fileName = [[fileURL lastPathComponent] componentsSeparatedByString:@"."];
NSLog(@"%@",[fileName objectAtIndex:0]);

Answer 2

This should work:) This will get all files in a directory in a NSString *parentDirectory, get its size, if image do something otherwise it assumes is a sound file

NSFileManager *fm = [NSFileManager defaultManager];
NSError *error = nil;
NSArray *filePaths = [fm contentsOfDirectoryAtPath:parentDirectory error:&error];
if (error) {
    NSLog(@"%@", [error localizedDescription]);
    error = nil;
}   
for (NSString *filePath in filePaths) {
    //filename without extension
    NSString *fileWithoutExtension = [[filePath lastPathComponent] stringByDeletingPathExtension];

    //file size
    unsigned long long s = [[fm attributesOfItemAtPath:[parentDirectory stringByAppendingPathComponent:filePath] 
                                  error:NULL] fileSize];

    UIImage *image = [UIImage imageNamed:[parentDirectory stringByAppendingPathComponent:filePath];];
    //if image...
    if(image){
        //show it here
    }
    else{
        //otherwise it should be music then, play it using AVFoundation or AudioToolBox
    }

}
