Swift UIView Brief animation

Swift UIView comes with some simple animations.

If this is not a complex requirement, consider using the method here.

Let's try it a little bit.

First create three views to set the three-in-one background color

        Let View1=uiview (Frame:cgrectmake (Ten, A, $)) Let        View2=uiview (Frame:cgrectmake ()        View3=uiview (Frame:cgrectmake, Max, max))        View1.backgroundcolor=uicolor.redcolor ()        View2.backgroundcolor=uicolor.greencolor ()        View3.backgroundcolor=uicolor.bluecolor (        ) Self.view.addSubview (View1)        Self.view.addSubview (view2)        Self.view.addSubview (VIEW3)

Down we add an animation to View1, let him delay 1 seconds to execute, and eventually enlarge his size to 300.300, the position is unchanged. Colors fade into Blue

            Uiview.animatewithduration (2,            delay:1, Options:UIViewAnimationOptions.CurveEaseInOut, animations: {() Void in                View1.frame=cgrectmake (ten, +)                View1.backgroundcolor=uicolor.bluecolor ()                        }) {( Finished), Void in                        }

You can see the effect when you run it.

We see a closure on the top finished not used

We can try to use

            Uiview.animatewithduration (2, delay:1, Options:UIViewAnimationOptions.CurveEaseInOut, animations: {(), Void in View1.frame=cgrectmake (ten, +, +) VIEW1.BACKGROUNDCOLOR=UICOLOR.BL                    Uecolor ()}) {(finished), Void in Uiview.animatewithduration (2, Delay:1, Options:UIViewAnimationOptions.CurveEaseInOut, animations: {(), Void in view1.fr                                            Ame=cgrectmake (Ten, A, View1.backgroundcolor=uicolor.redcolor) ()                            }) {(finished), Void in Uiview.animatewithduration (2,                                Delay:1, Options:UIViewAnimationOptions.CurveEaseInOut, animations: {(), Void in                                View1.frame=cgrectmake (Ten, View1.backgroundcolor=uicolor.bluecolor) ()                            }) {(finished), Void in} }        }

OK, run to see the effect.

Simple effect to say, you can continue to try new features, there are problems can be added group discussion
