Snapkit of Swift control constraints

A. Attach Snapkit at GitHub address: https://github.com/SnapKit/SnapKit

Official guidance Add constraint: Https://github.com/SnapKit/SnapKit#usage

Snapkit 3.0 Migration guide:https://github.com/snapkit/snapkit/blob/master/documentation/snapkit%203.0% 20migration%20guide.md

Second, the specific use

Swift 3.0 uses lazy loading

 //AvatarLazy var Headerimageview:uiimageview ={Let Imgview:uiimageview=Uiimageview () Imgview.backgroundcolor=uicolor.redreturnImgview} ()        //titleLazy var Titlelabel:uilabel ={Let Time:uilabel=UILabel () Time.font= Uifont.boldsystemfont (ofsize: the) Time.Text="work notifications: IOS"        returnTime } ()        //TimeLazy var Timelabel:uilabel ={Let Time:uilabel=UILabel () Time.font= Uifont.systemfont (ofsize:Ten) Time.textcolor=Uicolor.lightgray Time.Text="Yesterday"time.textalignment=.

NonereturnTime } ()            //DescriptionLazy var Descriptionlabel:uilabel ={Let Time:uilabel=UILabel () Time.font= Uifont.systemfont (ofsize: -) Time.textcolor=Uicolor.lightgray Time.Text="[Time Clock] there are six minutes to go to work, ..."time.textalignment=.

To add a constraint to a control by using Snapkit

Func addsubviews ()Void {self.addsubview (Self.headerimageview) Self.addsubview (Self.titlelabel) SELF.ADDSU                Bview (Self.timelabel) Self.addsubview (Self.descriptionlabel) Self.addsubview (Self.nohandlelabel) //Avatarself.headerImageView.snp.makeConstraints {(make)inchMake.left.equalToSuperview ().
