A simpler way to add all images from directory to MWPhotoBrowser?

Question

My knowledge about objective c is limited, I have found a way to do what I need. I just don't think it's efficient at all.

I'm trying to add all images from a directory outside the application bundle to the MWPhotoBrowser. Problem is, they wont have specific names for ex. 2f5h3h5y.png.

NSMutableArray *photos = [[NSMutableArray alloc] init];

NSMutableArray *myArray = [[NSMutableArray alloc] init];
NSString *filePath = @"/Library/Application Support/Testing/Testing";
NSString *absolutePath;



MWPhoto *photo;
switch (indexPath.row) {
    case 0:

        myArray = [[[NSFileManager defaultManager] contentsOfDirectoryAtPath:filePath error:NULL] mutableCopy];

        NSLog(@"~~~~~~~~~~~~MY ARRAY COUNT: %d", [myArray count]);

        if ([myArray count] == 1){

            absolutePath = [NSString stringWithFormat:@"%@/%@", filePath, [myArray objectAtIndex:0]];

            photo = [MWPhoto photoWithFilePath:absolutePath];
            [photos addObject:photo];

        } else if ([myArray count] == 2){

            absolutePath = [NSString stringWithFormat:@"%@/%@", filePath, [myArray objectAtIndex:0]];

            photo = [MWPhoto photoWithFilePath:absolutePath]; 
            [photos addObject:photo];

            absolutePath = [NSString stringWithFormat:@"%@/%@", filePath, [myArray objectAtIndex:1]];

            photo = [MWPhoto photoWithFilePath:absolutePath];
            [photos addObject:photo];

        } else if ([myArray count] == 3){

            absolutePath = [NSString stringWithFormat:@"%@/%@", filePath, [myArray objectAtIndex:0]];

            photo = [MWPhoto photoWithFilePath:absolutePath];
            [photos addObject:photo];

            absolutePath = [NSString stringWithFormat:@"%@/%@", filePath, [myArray objectAtIndex:1]];

            photo = [MWPhoto photoWithFilePath:absolutePath];
            [photos addObject:photo];

            absolutePath = [NSString stringWithFormat:@"%@/%@", filePath, [myArray objectAtIndex:1]];

            photo = [MWPhoto photoWithFilePath:absolutePath];
            [photos addObject:photo];

        }

I know this method will not work because I can't set up a 1000 of "if statements." A crash would result if they were out of bounds. Can anyone provide a working example for what I need. An explanation would be appreciated. Thanks

You need to learn about loops.

NSMutableArray *photos = [[NSMutableArray alloc] init];
NSString *filePath = @"/Library/Application Support/Testing/Testing";
NSArray *myArray = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:filePath error:nil];
for (NSString *filename in myArray) {
    NSString *fullPath = [filePath stringByAppendingPathComponent:filename];
    MWPhoto *photo = [MWPhoto photoWithFilePath:fullPath];
    [photos addObject:photo];
}

BTW - this code will only work in the simulator since you are hard coding the library path.

This code also assumes that the only files in the directory are image files.
