Swift UIView Common Add method

There are several common ways to add UIView Swift

    Func Insertsubview (View:uiview, Atindex index:int)    func addsubview (view:uiview)    func insertsubview (view: UIView, Belowsubview Siblingsubview:uiview)    func insertsubview (View:uiview, Abovesubview Siblingsubview:uiview)

First, the most common addsubview is the normal addition

        Let View1=uiview (Frame:cgrectmake (Ten, (), ()) Let        View2=uiview (Frame:cgrectmake        ) View1.backgroundcolor=uicolor.redcolor ()        View2.backgroundcolor=uicolor.greencolor (                ) Self.view.addSubview (View1)        Self.view.addSubview (VIEW2)

Let's see the effect.

Parsing let's take a look at Self.view's sub-view and then we know the index of the two views we just added

        var arr:[anyobject]        arr = self.view.subviews;        println ("arr=%d", Arr.count)

The result is 4, then View1 index is 2,VIEW2 index is 3

Let's take a look at this method.

Insertsubview (view:UIView, atindex index: Int)

Add View to

        Let Blueview=uiview (Frame:cgrectmake () (+,,,)        Blueview.backgroundcolor=uicolor.bluecolor ()        Self.view.insertSubview (Blueview, Atindex:3)

The effect is as follows

We can see that Blueview was added between View1 and View2.

All that means is to add the view to the specified location.

Come down to us two ways to compare

    Func Insertsubview (View:uiview, Belowsubview siblingsubview:uiview)    func insertsubview (View:uiview, Abovesubview Siblingsubview:uiview)

        Let Orangeview=uiview (Frame:cgrectmake ()        Orangeview.backgroundcolor=uicolor.orangecolor ()        Self.view.insertSubview (Orangeview, Belowsubview:blueview) let                Purpleview=uiview (Frame:cgrectmake (130,        Purpleview.backgroundcolor=uicolor.purplecolor ()        Self.view.insertSubview (Purpleview, Abovesubview:blueview)

The effect is as follows

We saw that he was talking about the new two view separately add the top and bottom of the Blueview

All right, let's look at it.
