IOS: Get the first letter of Pinyin using swift, and get the first letter of every word in a sentence, iosswift

In a recent project, I encountered the problem of getting the first letter of Pinyin. I searched for the online method and did not find a suitable and useful method. So I did some research and wrote the following methods. Please feel free to contact me, I hope to help you.
