I want to shift left bar button to extreme left of the navigation bar. by using this code I can able to shift this. I noticed button is not responsive from 20 px from left side(before arrow in yellow rectangle, its not responsive). From middle of the button it is responsive and go to back screen. how to fix this. I used following code
let suggestButton = UIButton(type: UIButton.ButtonType.custom)
suggestButton.frame = CGRect(x: 0, y: 0, width: 60, height: 40)
suggestButton.setImage(backImage, for: UIControl.State.normal)
suggestButton.backgroundColor = .green
suggestButton.imageEdgeInset = UIEdgeInset()top: 10.0, left: 5.0, bottom: 10.0, right : 35)
suggestButton.addTarget(self, action: #selector(self.showPopover(sender:)), for:.touchUpInside)
suggestButton.transform = CGAffineTransform(translationX: -15, y: 0)
let suggestButtonContainer = UIView(frame: suggestButton.frame)
suggestButtonContainer.addSubview(suggestButton)
let suggestButtonItem = UIBarButtonItem(customView: suggestButtonContainer)
navigationItem.leftBarButtonItem = suggestButtonItem

I follow a video from youtube. And i ran into a problem when ı try to set Navigation Controller items.
func setupNavigationBarItems() {
let twitterImage = UIImageView(image: UIImage(named: "twitter_icon"))
twitterImage.frame = CGRect(x: 0, y: 0, width: 20, height: 20)
twitterImage.contentMode = .scaleAspectFit
navigationController?.navigationItem.titleView = twitterImage
let profileButton = UIButton(type: .system)
profileButton.setImage(UIImage(named: "profile_image"), for: .normal)
profileButton.frame = CGRect(x: 0, y: 0, width: 20, height: 20)
navigationController?.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: profileButton)
}
Result
This is the result. Nothing show up
Edit--
I made same changes
navigationController?.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: profileButton)
--
navigationItem.leftBarButtonItem = UIBarButtonItem(customView: profileButton)
it just shows the profileButton and button stretches all over to the edges
new result

(Build Project first and you will see this button)
Swift 4.2 implemented views programmatically only
I have created a stack view and put four buttons in it but they are just simple buttons without any gray background.
I want to achieve the exact four buttons in my stackview equally centered as like as -
button.contentEdgeInset //Not working
This is what I tried -
let feedbackButton:UIButton = {
let origImage = UIImage(named: "feedback")
let tintedImage = origImage?.withRenderingMode(.alwaysTemplate)
let button = UIButton(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
button.translatesAutoresizingMaskIntoConstraints = false
button.setBackgroundImage(tintedImage, for: UIControl.State.normal)
button.tintColor = .systemPinkColor
button.layer.cornerRadius = 7
button.backgroundColor = UIColor.lightGray.withAlphaComponent(0.5)
button.contentEdgeInsets = UIEdgeInsets(top: 0, left: 40, bottom: 0, right: 40)
// button.imageEdgeInsets = UIEdgeInsets(top: 0, left: 50, bottom: 0, right: 50)
// button.titleEdgeInsets = UIEdgeInsets(top: 0, left: 50, bottom: 0, right: 50)
button.clipsToBounds = true
button.addTarget(self, action: #selector(feedbackFaculty), for: .touchUpInside)
return button
}()
Output -
The button's image gets stretched along with insets. button.imageInsets and button.titleInsets not working.
Help me out. Thanks!
The background image doesn't follow the content insets. So this line:
button.setBackgroundImage(tintedImage, for: UIControl.State.normal)
needs to be changed to:
button.setImage(tintedImage, for: .normal)
Also, here's a couple things to note (per Apple's UIButton documentation):
Supply a title string or image; size the button appropriately for your content.
Which implies that you cannot set an image and title at the same time, this might be why you're noticing titleInset and imageInset not playing nicely.
However, if you just set appropriate constraints for the buttons and set insets for the title OR the image you should be able to get the look you want. Also make sure your stack view is configured to use equal spacing for it's distribution.
The imageInset for each button in the image below is (20, 20, 20, 20).
let SearchView = UIView()
SearchView.backgroundColor = UIColor.clear
SearchView.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
let Searchbutton = UIButton(type: .system)
Searchbutton.setImage(UIImage (named: "SEARCH"), for: .normal)
Searchbutton.backgroundColor = .clear
Searchbutton.frame = CGRect(x: -17, y: -20, width: 30, height: 30)
Searchbutton.contentMode = .scaleAspectFit
let WidthConstraint = Searchbutton.widthAnchor.constraint(equalToConstant: 30)
let HeightConstraint = Searchbutton.heightAnchor.constraint(equalToConstant: 30)
WidthConstraint.isActive = true
HeightConstraint.isActive = true
let barButtonItem = UIBarButtonItem(customView: SearchView)
self.navigationItem.rightBarButtonItem = barButtonItem
SearchView.addSubview(Searchbutton)
Searchbutton.addTarget(self, action: #selector(viewanewcontroller(button:)), for: .touchUpInside)
//right search button
After making a button, I wanted to move it little bit to the right. So, i made UI View to move the button inside the view. But, then, after this, the button does not work anymore. Can anyone tell me the solution?
Your code is working fine but need to clarify some points.
Reason Your button not working is below 4 lines
let WidthConstraint = Searchbutton.widthAnchor.constraint(equalToConstant: 30)
let HeightConstraint = Searchbutton.heightAnchor.constraint(equalToConstant: 30)
WidthConstraint.isActive = true
HeightConstraint.isActive = true
As you already set UIButton frame then no need to use of above lines of code.
Yellow color view is your SearchView and green color is your UIButton.
If you use Searchbutton frame like Searchbutton.frame = CGRect(x: -17, y: -20, width: 30, height: 30) then it happens something like below image.
You added UIButton as subview of UIView and when you click on green button which is inside yellow View will work but the area which is outside Yellow area doesn't work.
You need to start UIButton frame from 0,0,30,30
Searchbutton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
or you can directly set UIButton frame same as UIView frame then it looks like below image.
Searchbutton.frame = SearchView.frame
Below is your Working Code.
let SearchView = UIView()
SearchView.backgroundColor = UIColor.clear
SearchView.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
let Searchbutton = UIButton(type: .system)
Searchbutton.setImage(UIImage (named: "SEARCH"), for: .normal)
Searchbutton.backgroundColor = .clear
Searchbutton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
Searchbutton.contentMode = .scaleAspectFit
let barButtonItem = UIBarButtonItem(customView: SearchView)
self.navigationItem.rightBarButtonItem = barButtonItem
SearchView.addSubview(Searchbutton)
Searchbutton.addTarget(self, action: #selector(viewanewcontroller(button:)), for: .touchUpInside)
//right search button
You're doing a lot of unnecessary things here. Firstly, you don't need to put your Button in a container view to put it as the right bar button item.
You also don't need to add constraints to your searchbutton, since you have given it a fixed frame.
let Searchbutton = UIButton(type: .system)
Searchbutton.setImage(UIImage (named: "SEARCH"), for: .normal)
Searchbutton.backgroundColor = .clear
Searchbutton.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
Searchbutton.contentMode = .scaleAspectFit
let barButtonItem = UIBarButtonItem(customView: Searchbutton)
self.navigationItem.rightBarButtonItem = barButtonItem
Searchbutton.addTarget(self, action: #selector(viewanewcontroller(button:)), for: .touchUpInside)
Also as Pratik's comment said, you're meant to use lower camel case. so SearchView should be searchView and SearchButton as searchButton
As for moving it to the right, it seems like that isn't possible anymore without either subclassing the UINavigationBar and changing the implementation, or by making UIViews look exactly like the standard Navigation Bar.
Get rid of the space on the right side of a UINavigationBar
I am having some difficulties creating a bar button that are leaving me pretty stumped. Im using the following code to create a right bar button:
let button = UIButton(frame: CGRect(x: 0, y: 0, width: 22, height: 22))
button.setBackgroundImage(UIImage(named: "tune"), for: .normal)
button.addTarget(self, action:#selector(viewController.settingsBtnPressed), for:.touchUpInside)
self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: button)
No matter what I set the width or height as the button size does not change. The VC is in a navigation controller. Does anyone have any insight or next steps I can take? Any help would be appreciated
Click on your ViewController in StoryBoard. Go to "Editor" -> "Embed In" -> Click on "Navigation Controller".After that paste the code in your ViewDidLoad method where you want to see the BarButton.
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton(frame: CGRect(x: 0, y: 0, width: 22, height: 22))
button.setBackgroundImage(UIImage(named: "tune"), for: .normal)
button.addTarget(self, action:#selector(ViewController.settingsBtnPressed), for:.touchUpInside)
self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: button)
}
// The height and minimum value of this button will be affected by the rightBarButtonItem
Button height is 100000
Button height is 0
[ You can this ]
// Provide a vew to button
let tView = UIView(frame: CGRect(x: 0, y: 0, width: 30, height: 40));
tView.backgroundColor = UIColor.darkGray
let button = UIButton(frame: CGRect(x: 0, y: 0, width: 20, height: 22))
//button.setBackgroundImage(UIImage(named: "tune"), for: .normal)
button.backgroundColor = UIColor.green;
button.addTarget(self, action:#selector(ViewController.settingsBtnPressed), for:.touchUpInside)
// add btton to tView
tView.addSubview(button)
self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: tView)
Turns out that the problem arises due to how bar buttons are handled in iOS 11. UIBarButtonItemnow uses autolayout instead of frames. As a result, the following code allows you to adjust the size of the button:
button.widthAnchor.constraint(equalToConstant: 22.0).isActive = true
button.heightAnchor.constraint(equalToConstant: 22.0).isActive = true
I set a button to right side of navigation bar:
my view controller:
I want to set a burger icon,red cycle and a label to this button. like this:
my code:
self.navigationController?.navigationBar.barTintColor = self.utilities.hexStringToUIColor(hex: "#00b8de")
var imageview2 = UIImage(named: "menulogo")
imageview2 = imageview2?.imageResize(sizeChange: CGSize(width: 25, height: 25))
btnMenu.setImage(imageview2,for:UIControlState.normal)
btnMenu.setTitle("", for: .normal)
// setup the red circle UIView
let redCircleView = UIView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
redCircleView.backgroundColor = UIColor.red
redCircleView.layer.cornerRadius = view.frame.size.width / 2
// setup the number UILabel
let label = UILabel(frame: CGRect(x: 30, y: 0, width: 20, height: 20))
label.textColor = UIColor.white
label.font = UIFont.systemFont(ofSize: 10)
label.text = "16"
// adding the label into the red circle
redCircleView.addSubview(label)
// adding the red circle into the menu button
btnMenu.addSubview(redCircleView)
with above codes I have three problems:
my burger image isn't in most right side of navigation.
my cycle view doesn't show
my icon is white, but it shows blue!
btnMenu is my button in navigation.
I have use this library for set badge on navigation button.
