Question

I’m using the HSImageSidebarView and in the example included in the open source project, this is how to load the images in the sidebar :

-(UIImage *)sidebar:(HSImageSidebarView *)sidebar imageForIndex:(NSUInteger)anIndex {
    int color = [[colors objectAtIndex:anIndex] intValue];
    switch (color % 3) {
        case 0:
            return [UIImage imageNamed:@"Blue"];
            break;
        case 1:
            return [UIImage imageNamed:@"Red"];
            break;
        default:
            return [UIImage imageNamed:@"Green"];

    }
}

What my problem is how to add my own images from the NSDocumentDirectory. Here is my array :

self.images = [NSMutableArray new];  
for(int i = 0; i <= 100; i++) 
{ 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDir = [paths objectAtIndex:0];

    NSString *savedImagePath = [documentsDir stringByAppendingPathComponent:[NSString stringWithFormat:@"Images%d.png", i]]; 
    NSLog(@"savedImagePath=%@",savedImagePath);

    if([[NSFileManager defaultManager] fileExistsAtPath:savedImagePath]){ 
        [images addObject:[UIImage imageWithContentsOfFile:savedImagePath]]; 
        NSLog(@"file exists");
    } 
    NSLog(@"file does not exist");
} 

Thanks for the help!

Would do something like this.

-(UIImage *)sidebar:(HSImageSidebarView *)sidebar imageForIndex:(NSUInteger)anIndex {

    return (UIImage*)[self.images objectAtIndex:anIndex];

}

You’re storing UIImage‘s into your images array already. So there is no need to use the -imageNamed: method like the example. Instead what you do is return the image at said index from your images array with the objectAtIndex: method.

Hope this helps.
