Boleh diubah suai, dan ini boleh dicapai melalui carian kvc atau rekursif untuk subview.

@interface UIView (FindView)

- (UIView *)findViewWithClassName:(NSString *)aName;

@end


@implementation UIView (FindView)

- (UIView *)findViewWithClassName:(NSString *)aName {
    NSLog(@"%@", self);
    if([[[self class] description] isEqualToString:aName])
        return self;

    for(UIView *subview in self.subviews) {
        UIView *huntedSubview = [subview findViewWithClassName:aName];

        if(huntedSubview != nil)
            return huntedSubview;
    }
    return nil;
}

@end

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *prefix    = @"UITableViewCell";
    NSString *suffix    = @"EditControl";
    NSString *className = [prefix stringByAppendingString:suffix];
    UIView *view = [cell findViewWithClassName:className];
    view.backgroundColor = [UIColor redColor];
    NSLog(@"%@", view);
