繼續做仿造著別人的第二個

1.首先下載 一些字型 網上搜尋 "造字工房" 

2.把下載的相應字型檔放到工程之中，就Ok了

不多說 效果如下

可以下面這個方法 檢索項目裡面所有的字型

   for family in UIFont.familyNames {                        for font in UIFont.fontNames(forFamilyName: family) {                                print(font)                            }                    }

代碼如下

import UIKitclass ViewController: UIViewController {    lazy var contentLabel = UILabel()    lazy var changeBtn = UIButton()    var tag: Int = 0            override func viewDidLoad() {        super.viewDidLoad()       /* for family in UIFont.familyNames {                        for font in UIFont.fontNames(forFamilyName: family) {                                print(font)                            }                    }*/                self.view.backgroundColor = UIColor.black        contentLabel.frame = CGRect(x: 10, y:20, width:UIScreen.main.bounds.size.width - 20, height: 200)        contentLabel.numberOfLines = 0        contentLabel.textColor = UIColor.white        contentLabel.font = UIFont.systemFont(ofSize: 20)        self.view.addSubview(contentLabel)        let content: String = "30 Days Swift\n\n 目前授權個人免費非商業使用\n\n 所以捐款了1元下了3款字型用來做實驗\n\n 分別是造字工房勁黑，致黑和童心；"        contentLabel.text = content                changeBtn.backgroundColor = UIColor.orange        changeBtn.frame.size = CGSize(width: 100, height: 100)        changeBtn.frame.origin = CGPoint(x: UIScreen.main.bounds.size.width/2 - 50, y: UIScreen.main.bounds.size.height - 120)        changeBtn.setTitle("改變字型", for: .normal)        changeBtn.layer.masksToBounds = true        changeBtn.layer.cornerRadius = 50.0        changeBtn.addTarget(self, action: #selector(changeFont), for: .touchUpInside)        self.view.addSubview(changeBtn)     }        //MARK: - 點擊事件    func changeFont() {        var fontName:String        switch tag {        case 0:            fontName = "MFQingShu_Noncommercial-Regular"            tag = 1        case 1:            fontName = "MFYueYuan_Noncommercial-Regular"            tag = 2        case 2:            fontName = "MFWenYan_Noncommercial-Regular"            tag = 3        default:            fontName = "AppleSDGothicNeo-Regular"            tag = 0        }                contentLabel.font = UIFont.init(name: fontName, size: 20)    }            override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }}
