我如何在导航栏ios的中心获得两个按钮

Question

I would like to implement the following image in Swift for my navigation bar. I have tried the following code, however, it just stack the buttons on top of each other

let fromButton:UIButton = UIButton(frame: CGRectMake(0,0,80,44))
let toButton:UIButton = UIButton(frame: CGRectMake(80,0,80,44))

fromButtonView.bounds = fromButton.frame
fromButton.addSubview(fromButtonView)

toButtonView.bounds = toButton.frame
toButton.addSubview(toButtonView)

var myView:UIView = UIView(frame: CGRectMake(0,0,160,44))

myView.addSubview(toButton)
myView.addSubview(fromButton)

self.navigationItem.titleView = myView

fromButtonView and toButtonView are variables with the views implemented as xibs.

The resulting navigation header looks as follows, can't figure out where I am going awry. The views are stacking on top of each other.

Answer 1

let testFrame : CGRect = CGRectMake(0,0,180,40)

var buttonView: UIView = UIView(frame: testFrame)


var button1 =  UIButton.buttonWithType(UIButtonType.Custom) as UIButton

button.frame = CGRectMake(0, 0, 40, 40) as CGRect

button.backgroundColor = UIColor.redColor()

button.setTitle("Button", forState: UIControlState.Normal)


var button2 =  UIButton.buttonWithType(UIButtonType.Custom) as UIButton

button.frame = CGRectMake(70, 0, 40, 40) as CGRect

button.backgroundColor = UIColor.redColor()

button.setTitle("Button", forState: UIControlState.Normal)

buttonView.addSubview(button1)

buttonView.addSubview(button2)

self.navigationItem.titleView = buttonView
