Overview of this book

Do you want to understand all the facets of iOS programming and build complex iOS apps? Then you have come to the right place. This problem-solution guide will help you to eliminate expensive learning curves and focus on specific issues to make you proficient at tasks and the speed-up time involved. Beginning with some advanced UI components such as Stack Views and UICollectionView, you will gradually move on to building an interface efficiently. You will work through adding gesture recognizer and touch elements on table cells for custom actions. You will work with the Photos framework to access and manipulate photos. You will then prepare your app for multitasking and write responsive and highly efficient apps. Next, you will integrate maps and core location services while making your app more secure through various encryption methods. Finally, you will dive deep into the advanced techniques of implementing notifications while working with memory management and optimizing the performance of your apps. By the end of the book, you will master most of the latest iOS 10 frameworks.

Using filters with CoreImage

You may have the Instagram app in your device or will at least have come across a few photo editing apps and edited some photos by applying filters to enhance or change the look of your photo. Nowadays, photo editing apps are invading the App Store with unique and funny filters that you can use. In this section, we will see how to deal with the CoreImage framework to apply built-in filters to photos.

How to do it...

To apply built-in filters to photos, perform the following steps:

Create a new Xcode project with the Single View Application template and name it ImageFilters.
Add UIImageView with the following constraints and set any image of your choice:

      ImageView.leading = Superview.leading...

Visually different images
