uitabbarcontroller

问题 I have four ViewController, I don't use an UITabbedbar because It's more difficult to customize. I use modal segue but I think the memory consumption is excessive. this is a screen shot of my first and second VC. What I have to use to change View correctly? That's the code I use : override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) { if (segue.identifier == "second") { let secondVC = segue.destinationViewController as SecondViewController; } } 回答1: From your Storyboard

问题 In my application I'm using a Navigation Controller to push one view that loads a Tab Bar Controller and a custom Navigation Bar as well. The problem is that the Tab Bar disappears below the bottom of the screen, and I don't know what's causing the problem.

The appdelegate calls for a web fetch (via a custom class) and takes that web response and pareses it (via a custom class) and then puts the info in a CD-db (via a custom class).
