Swift Weibo visitor View

Modify Global Colors       
Uinavigationbar.appearance (). Tintcolor = Uicolor.orangecolor ()

Uitabbar. Appearance(). Tintcolor = uicolor. Orangecolor()

1. Create a basic view Baseview:uitableviewcontroller because the microblog shows Tablerview, the base view is also TableView

2. The following 4 controllers (first page find message i) are inherited Baseview:uitableviewcontroller

3. In Loadview, determine if login (flag) is true to display the microblog information (Super.loadview) (because the controller relationship is uitableviewcontroller->basicview-> Homeviewcontroller Basic If the Loadview method of calling the parent class is to display Homeviewcontroller directly) false invokes the Setupvisitor () method that you wrote to display the guest view

4.visitorview:uiview (UIView is enough,)

* Need to call initWithFrame construction method because this method is called in the hand layout to add and layout controls in this method

    Override Init (frame:cgrect) {        super.init (frame:frame)                setupui ()    }    required init (coder Adecoder:nscoder {        fatalerror ("init (coder:) have not been implemented")    }
