Hey, I'm having issues setting up the slider with swift.

     let listSlider = CategorySliderView.init(frame: CGRectMake(0 , 0, 60, self.view.frame.width),
            andCategoryViews: List.getAll(),
            sliderDirection: SliderDirection.Horizontal,
            categorySelectionBlock: { (categoryView: UIView!, index: Int) -> Void in
                print("index: \(index)")
        })

or

        let listSlider = CategorySliderView(sliderHeight: 60.0,
            andCategoryViews: List.getAll()) { (categoryView: UIView!, index: Int) -> Void in
                print("index: \(index)")
        }

Either way, I'm getting the error I'm getting below:

How would you recommend to set up the slider in swift?

Hi, I've been trying to translate this tiny part of code into Swift.. can someone help?

CategorySliderView *sliderView = [[CategorySliderView alloc] initWithSliderHeight:60 andCategoryViews:@[category1, category2, category3] categorySelectionBlock:^(UIView *categoryView, NSInteger categoryIndex) { UILabel *selectedView = (UILabel *)categoryView; NSLog(@""%@" cateogry selected at index %d", selectedView.text, categoryIndex); }];

Hi,

I'm unable to set the backgroundColor of an initialized CategorySliderView. This code doesn't work and the view still has a yellow background, is there a trick to setting the background color or am I missing something?

[self.sliderView setBackgroundColor:[UIColor redColor]];

I found where this is hardcoded to yellow in the .m file, would you take a pull request to add setting the bgColor to the initWithFrame.... initializer like:

- (instancetype)initWithFrame:(CGRect)frame andCategoryViews:(NSArray *)categoryViews sliderDirection:(SliderDirection)direction categorySelectionBlock:(categorySelected)block withBackgroudColor:(UIColor *)bgColor;

EDIT:
I discovered that if I remove line 53: https://github.com/cemolcay/CategorySliderView/blob/master/CategorySliderView/CategorySliderView.m#L53 I'm able to set the backgroundColor in my instantiated CategorySlider. I'm happy to create a pull request to remove the [self.scrollView setBackgroundColor:[UIColor yellowColor]]; line and/or create an initializer. Let me know if you have a preference

If the user needs updated buttons showing x followers each time the user enters his/hers profile and that x value is fetched async from the web in viewWillAppear, how can you then update the button with the value x when the callback comes in? In other words, how can you update the buttons after they first have been laid out?

Thank you for your time Alexander
