Swift UILabel Text size adjusts with width

The width of Swift Uilabel is generally fixed, but the text is sometimes long and sometimes short, how to do the text after the label width of the appropriate narrowing so that the reality completely

In fact, a lot simpler we call

Adjustsfontsizetofitwidth

can be achieved

                Let Label1=uilabel (Frame:cgrectmake (+, +))        label1.text= "Test Swift UILabel here to test the text size and label width adaptive and set minimum scaling"        Self.view. Addsubview (Label1)        label1.backgroundcolor=uicolor.graycolor () let                        Label2=uilabel (frame: CGRectMake (+, (+), (+))        label2.text= "Test Swift UILabel here to test the text size and label width adaptive"        Label2.adjustsfontsizetofitwidth=true        self.view addsubview (label2)        label2.backgroundcolor= Uicolor.graycolor () Let                        Label3=uilabel (Frame:cgrectmake (),        label3.text= "test Swift UILabel Here to test the text size and label width adaptive "        label3.adjustsfontsizetofitwidth=true        //0.6 Here is reduced to 0.6 times times not shrunk, if still more than then omit the reality superfluous part        label3.minimumscalefactor=0.6        self.view addsubview (label3)        label3.backgroundcolor= Uicolor.graycolor ()

Perform the above code test results
