wanting to set the size for the image that show in the simulator as it comes up far to big i've tried many thing to no avail ?
func CancelButton(){
navigationItem.leftBarButtonItem = UIBarButtonItem(image:
#imageLiteral(resourceName: "HOME BUTTON BLACK").withRenderingMode(.alwaysOriginal), style: .plain, target: self, action: #selector(handleCancel))
}
func handleCancel() {
self.dismiss(animated: true, completion: nil)
}// handleCancel
You need a smaller image!
You can either do this in code, or replace the current image with a smaller one.
For bar button items, the best size is around 25x25, so try to resize it to that.
To do it in code, you can refer to this answer.

I recently started having an issue where the popover controller will some times show up on the wrong corner. When it works correctly, the popover source is a button on the upper right corner. This is what happens most o the time. Now, when I land on this page "too quickly" from a specific route, the popover shows up on the upper left corner.
Another thing that is weird is that when loading is artificially delayed (like when I set break points for debugging) the popover shows up correctly.
Since it seemed to be a timing issue, I tried moving the navigation configuration from viewDidLoad to viewDidAppear, but this didn't work.
This function is called from viewDidLoad:
func configureNav() {
if canAddDoc == true {
let customButton = UIButton(type: .system)
customButton.setImage(with: .add, tintColor: UIColor.white, imageEdgeInsets: UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10))
customButton.addTarget(self, action: #selector(showAddDocSheet), for: .touchUpInside)
addButton = UIBarButtonItem(customView: customButton)
}
shareButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.action,
target: self,
action: #selector(shareButtonPressed))
navigationItem.rightBarButtonItems = (addButton == nil) ? [shareButton!] : [shareButton!, addButton!]
#objc func showAddDocSheet() {
guard let addButton = addButton else { return }
self.displayActionSheet(sourceButton: addButton)
}
}
func displayActionSheet(sourceButton: UIBarButtonItem) {
let actionSheet = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
//Action sheet code goes here
if let popoverController = actionSheet.popoverPresentationController {
popoverController.barButtonItem = sourceButton
popoverController.sourceView = sourceButton.customView
popoverController.permittedArrowDirections = .up
}
self.present(actionSheet, animated: true, completion: nil)
}
This may sound a weird solution but something similar happened to me before and it got solved when setting the animation to false while presenting the VC ,
self.present(actionSheet, animated: false, completion: nil)
there is one screen that i don't want to show back button symbols.
i create a empty image and change the navigation bar back button image.(code like following)
navigationController?.navigationBar.backIndicatorImage = UIImage(named: "mainicon_gray-13")
navigationController?.navigationBar.backIndicatorTransitionMaskImage = UIImage(named: "mainicon_gray-13")
navigationItem.backBarButtonItem = UIBarButtonItem(title: "demo", style: .plain, target: nil, action: nil)
screen like following Picture
But all of backBarButtonItem changed, i need to set backBarButtonItem to default symbols "<" when i back to the view.
Is there any way to set navigation bar back button image to default image?
i want the navigationBar like following picture
following is the way that i found without change back button settings to do same event.
use leftBarButtonItem and set popViewController to go back before screen.
override func viewDidLoad() {
navigationItem.leftBarButtonItem = UIBarButtonItem(title: "test", style: .plain, target: self,action: #selector(backViewBtnFnc))
}
#objc func backViewBtnFnc(){
self.navigationController?.popViewController(animated: true)
}
I have a navigation bar on my viewcontroller.
I have created a custom image (of a cog) and have got that to show right:
//Add bar item
var image = UIImage(named: "settingsIcon")
image = image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
NavigationBar.rightBarButtonItem = UIBarButtonItem(image: image, style: UIBarButtonItemStyle.Plain, target: nil, action: "addTapped")
I added the action to the above code:
action: "addTapped"
Then I created a function:
func addTapped() {
print("Tapped")
}
When I run the app, the image shows fine. When I click the image nothing happens, not even an error.
Am I doing something blatantly wrong here?
Try setting the target to self instead of nil.
In my app, I am using SWRevealViewController. Currently everything is working OK except for the menu image position.I set up the menu button programatically. Now I need to put it to the correct place.It also needs to work in all screen sizes and needs to be at the same place.
I set up the menu button like this
override func viewDidAppear(animated: Bool) {
let image = UIImage(named: "reveal-icon#2x.png")
tabBarController?.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "", style:
UIBarButtonItemStyle.Plain, target: self.revealViewController(), action: Selector("revealToggle:"))
tabBarController?.navigationItem.leftBarButtonItem?.image = image
}
and here is the result
How do I fix it? I think I need to do it programatically...
And here is the overall layout of my storyboard file.
Thanks for your answers.
This might be happening because you are initializing the UIBarButtonItem with a title. Initialize it with something like this:
let img = UIImage(named: "reveal-icon#2x.png")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
let leftBarButtonItem = UIBarButtonItem(image: img, style: UIBarButtonItemStyle.Plain, target: self.revealViewController(), action: Selector("revealToggle:"))
tabBarController?.navigationItem.leftBarButtonItem = leftBarButtonItem
I have a UIToolbar, but I have no idea how to positioning it..
I would add UIBarButtonItems to it, and positioning them. The toolbar showing up, but i can't change it size, and i can't position the buttons in it.
override func viewDidAppear(animated: Bool) {
self.navigationController?.setToolbarHidden(false, animated: true)
self.navigationController?.toolbar.frame = CGRectMake(50, 50, 50, 50)
self.navigationController?.toolbar.sizeToFit()
let plusImg = UIImage(named: "navbar_icon-02.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
let plusButton = UIBarButtonItem(image: plusImg, style: UIBarButtonItemStyle.Plain, target: self, action: "postLeft:")
let filterButton = UIBarButtonItem(title: "Feed filter", style: UIBarButtonItemStyle.Plain, target: nil, action: nil)
let leftButton = UIBarButtonItem(title: "Button 3 tst", style: UIBarButtonItemStyle.Plain, target: nil, action: nil)
var toolbarButtons = [filterButton]
toolbarButtons.append(plusButton)
toolbarButtons.append(leftButton)
self.toolbarItems = toolbarButtons
}
There are two possible problems you might be having (I can't quite tell, from the way you've asked the question).
One problem might be that you are not in a navigation interface - you simply have a "loose" toolbar. Thus, the toolbar referred to through self.navigationController? is not your toolbar, and setting self.toolbarItems has no effect - those things are only for when you are in a navigation interface and the toolbar in question is the navigation controller's toolbar.
The other problem might be that you are in a navigation interface, in which case the toolbar position is not up to you - it's up to the navigation controller, which will always place it at the bottom of the screen.
So, either you need to be in a navigation interface so that the toolbar is the navigation controller's toolbar (and then your code will work, except for the positioning part), or else you can use a "loose" tolbar, in which case you need your code to refer to your toolbar, in which case you are free to position it, and you can give it items by setting its items.
