Changing the height of the Navigation bar iOS Swift

问题

I am trying to change the height of there navigation bar for my app. Currently the height is fixed to 44. I can change the width from Xcode but not the height.

I have no idea how to change this. Very new to iOS development.

Can anyone please help?

Try this :

import UIKit

class YourViewController : UIViewController {

    var navBar: UINavigationBar = UINavigationBar()

    override func viewDidLoad() {
        super.viewDidLoad()
        self.setNavBarToTheView()
        // Do any additional setup after loading the view.
        self.title = "test test"
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func setNavBarToTheView() {
        self.navBar.frame = CGRectMake(0, 0, 320, 50)  // Here you can set you Width and Height for your navBar
        self.navBar.backgroundColor = (UIColor.blackColor())
        self.view.addSubview(navBar)
    }
}

simply dragged and dropped it on my view

In that case, the simplest way is with constraints. Just give it a height constraint (along with the other constraints that position it). No code required! Here's an example:

That was achieved with no code at all. It's all done with constraints:

We are pinned to the top and sides of the superview, along with height constraint of 100.

I know this makes no sense, however this is what I did ( worked without laying down constraints ).

select your View Controller.
Open Show the attributes inspector
for top bar select any tab bar (I'm choosing translucent Tab Bar).
within the show the object library drag and drop the navigation item on the View Controller. (If done right, should look like image 3)
Additionally ( fyi ), you can add a constraint to your button, etc. with using no margins and top being set to 0.
