The code is as follows

Import UIKitclassViewcontroller:uiviewcontroller {lazy var contentlabel=UILabel () lazy var changebtn=UIButton () var tag:int=0            Overridefunc 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:TenY: -, Width:UIScreen.main.bounds.size.width- -, Height: $) Contentlabel.numberoflines=0Contentlabel.textcolor=Uicolor.white Contentlabel.font= Uifont.systemfont (ofsize: -) Self.view.addSubview (Contentlabel) let content:string="swift\n\n currently authorized personal free non-commercial use \ n \ nyou donated 1 yuan under the 3 font used to do the experiment \ n, respectively, is the word-making workshop black, black and childlike innocence;"Contentlabel.text=content Changebtn.backgroundcolor=Uicolor.orange changeBtn.frame.size= Cgsize (width: -, Height: -) ChangeBtn.frame.origin= Cgpoint (x:uiscreen.main.bounds.size.width/2- -, Y:uiscreen.main.bounds.size.height- -) Changebtn.settitle ("Change Font", for:.
