Sample Code

Introduction

Learning the usage of NSTextFinder, for implementing the elegant find function for your Application.

NSTextFinderClient

There are two very interesting properties as below:

            textFinder.incrementalSearchingShouldDimContentView = true
            textFinder.isIncrementalSearchingEnabled = true

In order to facilitate debugging and clarify the running process, the code adds a lot of console printing. Please forgive me. 😅
