Its extremely customisable, lightweight, has numerous hooks and many many predefined effects, its simply awesome! In this post, we will see how easy it is to get the iCarousel integrated into our app.
How Do They Do It!
To get this control up and running follow these simple steps
The installation is stock standard, you can install it via Cocoapods. Use the following line in your pod file
and then run
- There are two protocols that need to be implemented for the iCarousel to work correctly. iCarouselDataSource and iCarouselDelegate
- The iCarouselDataSource protocol has two mandatory methods to be implemented
- (NSInteger)numberOfItemsInCarousel: This method returns the number of items in the carousel
- (UIView *)carousel:viewForItemAtIndex:reusingView: This method returns the view that needs to be shown in the carousel.
- The iCarouselDelegate protocol has no mandatory methods but its good to implement the following method
- (CGFloat)carousel:valueForOption:withDefault: This method can return values for different options which alter the display and behaviour of the carousel.
In this snippet we are just initialising the iCarousel and setting the type of carousel to iCarouselTypeCoverFlow2, this type's behaviour closely mimics the App Cover Flow effect.
Next up are the protocol methods that we described earlier.
This snippet implements the two mandatory methods of iCarouselDataSource protocol. For the view we are showing a simple image from our assets. And we have total 4 items in our carousel.
The last and final method just customises two options of the iCarousel. It basically wraps the view so that we get an infinite view sort of a feeling and adjusts the spacing between the views a bit.
With all the pieces in place lets fire it off and see how it looks!
Pretty impressive for such little code, won't you agree?
That's all folks, until we meet again, Guten Tag!
