How to show image in overCurrentContext view in the ViewController2
.swift class ? I am doing this correctly when i worked manually but not doing when i using this programmatically in swift.
ViewController1.swift
code -
@IBAction func btnImage(_ sender: Any)
{
let imageVC = self.storyboard?.instantiateViewController(withIdentifier: "ImageVC") as! ImageVC
self.navigationController?.pushViewController(imageVC, animated: true)
}
ViewController2.swift
code -
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.setNavigationBarHidden(true, animated: true)
self.navigationController?.modalPresentationStyle = .overCurrentContext
}
I want this background alpha 0.7 and using .overCurrentContext
Output -
You are pushing your viewController, Instead you should present it with modalPresentationStyle .overCurrentContext
. Do something like this:
@IBAction func btnImage(_ sender: Any)
{
let vc = self.storyboard?.instantiateViewController(withIdentifier: "ImageVC") as! ImageVC
vc?.view.backgroundColor = UIColor.black.withAlphaComponent(0.7)
vc?.modalPresentationStyle = .overCurrentContext
vc?.navigationController?.isNavigationBarHidden = true
self.navigationController?.present(vc, animated: true, completion: nil)
}
For more information you can read more about modalPresentationStyle in Apple Docs.
