I am trying to add two buttons and a SearchBar to my navigation controller but the alignment is not correct. I have tried almost everything such as changing the size of SearchBar, UIButton or changing the Y positioning but it didn't work. Any idea how to fix this issue?
I am using iOS 11 and Xcode 9
searchController = UISearchController(searchResultsController: nil)
searchController?.searchBar.frame = CGRect(x: 0, y: 0, width: 200, height: 30)
searchController?.delegate = self
searchController?.searchResultsUpdater = self
let refineButton = UIButton.init(type: UIButtonType.custom)
refineButton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
refineButton.setImage(#imageLiteral(resourceName: "settings-button"), for: UIControlState.normal)
refineButton.widthAnchor.constraint(equalToConstant: 30).isActive = true
refineButton.heightAnchor.constraint(equalToConstant: 30).isActive = true
let refineItem = UIBarButtonItem(customView: refineButton)
navigationItem.leftBarButtonItem = refineItem
navigationItem.titleView = searchController?.searchBar
searchController?.searchBar.sizeToFit()
Please check :
override func viewWillLayoutSubviews() {
searchController?.searchBar.frame = CGRect(x: 0, y: 0, width: 300, height: 30)
searchController?.searchBar.sizeToFit()
}

I'd like to customize my navigation bar and insert a UIView with two subviews into the title view of the navigation bar.
Unfortunately the subviews aren't displayed.
Do you have any idea why?
let titleContainer = UIView()
titleContainer.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: UIScreen.main.bounds.size.height)
let searchIcon = UIButton()
searchIcon.setImage(UIImage(named: "search_icon"), for: UIControlState.normal)
searchIcon.layer.frame = CGRect(x: 0, y: (UIScreen.main.bounds.size.height - 28) / 2, width: 28, height: 28)
titleContainer.addSubview(searchIcon)
let titleLabel = UILabel()
titleLabel.frame = CGRect(x: 28, y: UIScreen.main.bounds.size.height, width: UIScreen.main.bounds.size.width-28, height: UIScreen.main.bounds.size.height)
titleLabel.textColor = UIColor(red:255, green:255, blue:255, alpha:1.0)
titleContainer.addSubview(self.titleLabel)
self.navigationItem.titleView = titleContainer
problem and expected solution:
Why did you use height of all the element as UIScreen.main.bounds.size.height? Please try the below code.
P.S. I have changed the color of searchIcon as i didn't have the image and changed the color of text of label and added some text so that it is visible.
let titleContainer = UIView()
titleContainer.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: 45)
let searchIcon = UIButton()
//searchIcon.setImage(UIImage(named: "search_icon"), for: UIControlState.normal)
searchIcon.backgroundColor = UIColor.red
searchIcon.layer.frame = CGRect(x: 0, y: 8, width: 28, height: 28)
titleContainer.addSubview(searchIcon)
let titleLabel = UILabel()
titleLabel.frame = CGRect(x: 28, y: 8, width: UIScreen.main.bounds.size.width-28, height: 30)
titleLabel.textColor = UIColor.blue//(red:255, green:255, blue:255, alpha:1.0)
titleContainer.addSubview(titleLabel)
titleLabel.text = "Sample Text"
self.navigationItem.titleView = titleContainer
Here is the screenshot of the above code:
Please change the x,y accordingly as per your requirement.
Have you considered making your let bar = UINavigationBar() programmatically and then add it with: self.view.addSubview(bar)?
So you can push all the "UIBarItems" you want..?
I try to add button and ImageView on NavigationItem. For this objects I added two functions TouchUp for it. This two objects I added on uiview. UIView I added to UINavigaionItem. I added UIGesture for ImageView and TouchUp action for button. But button and ImageView don't clicking.
The code bellow:
let navView = UIView()
navView.userInteractionEnabled = true
let btn = UIButton(type: UIButtonType.Custom) as UIButton
btn.addTarget(self, action: #selector(ViewController.on_clicked_btn(_:)), forControlEvents: UIControlEvents.TouchUpInside)
btn.frame = CGRectMake(-65, -22, 130, 42)
btn.setTitle("title", forState: .Normal)
btn.contentHorizontalAlignment = UIControlContentHorizontalAlignment.Center
btn.titleLabel?.lineBreakMode = NSLineBreakMode.ByWordWrapping
btn.titleLabel?.backgroundColor = UIColor.clearColor()
photo.frame = CGRect(x: -110, y: -18, width: 33, height: 33)
photo.layer.borderWidth = 0.5
photo.layer.masksToBounds = false
photo.layer.borderColor = UIColor.grayColor().CGColor
photo.layer.cornerRadius = self.photo_avatar.frame.height/2
photo.clipsToBounds = true
let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(ViewController.on_clicked_photo(_:)))
photo.addGestureRecognizer(tapRecognizer)
photo.userInteractionEnabled = true
navView.addSubview(photo)
navView.addSubview(btn)
self.navigationItem.titleView = navView
Any ideas? Thanks for your help.
It is because you were not initialising UIIview rect in:
let navView = UIView()
Replace this with
let navView = UIView.init(frame: CGRect.init(x: 0, y: 0, width: 168, height: 40))
Replace bin frame with:
btn.frame = CGRect(x: 38, y: 0, width: 130, height: 42)
and photo frame
photo.frame = CGRect(x: 0, y: 0, width: 33, height: 33)
I'm new to Swift. I have set my top bar programmatically.It works fine for all versions except for iOS version 11.
I want to change the background color of the safe area in iPhone X. Presently I have just added the following code to hide the status bar.
override var prefersStatusBarHidden: Bool {
return true
}
I have created top bar using code:
//Top Bar
let topBar = UIView(frame:CGRect(x: 0,y: 0, width: width, height: 60))
topBar.backgroundColor = UIColor.white
topBar.layer.shadowColor = UIColor.gray.cgColor
topBar.layer.shadowOffset = CGSize(width: 0, height: 3)
topBar.layer.shadowOpacity = 1
topBar.layer.masksToBounds = false
topBar.layer.shadowRadius = 8.0;
//ImageView - Back Button
let backBtn = UIButton(frame:CGRect(x: 25, y: 18, width: 18, height: 34))
let backBtnImage = UIImage(named: "back_button") as UIImage?
backBtn.setImage(backBtnImage, for: .normal)
backBtn.layer.masksToBounds = true
backBtn.addTarget(self,action:#selector(backButtonClicked),
for:.touchUpInside)
//Label - Title
let titleLabel = UILabel(frame:CGRect(x: width * 0.3, y: 13, width: width * 0.55, height: 40))
titleLabel.text = "Favorites"
titleLabel.contentMode = UIViewContentMode.center
//include all in view
topBar.addSubview(titleLabel)
topBar.addSubview(backBtn)
containerView.addSubview(topBar)
Is there a way in which i can do it without using UINavigationBar or setting status bar.
Hi you can also try this one ,
need to add a view with same background which you set in your header view and add to container parent view .
please refer below code
//Top Bar
let safeAreaView = UIView(frame:CGrect(x: 0,y: 0, width: width, height: 40))
safeAreaView.backgroundColor = UIColor.white
self.view.addSubview(safeAreaView)
let topBar = UIView(frame:CGRect(x: 0,y: 0, width: width, height: 60))
topBar.backgroundColor = UIColor.white
topBar.layer.shadowColor = UIColor.gray.cgColor
topBar.layer.shadowOffset = CGSize(width: 0, height: 3)
topBar.layer.shadowOpacity = 1
topBar.layer.masksToBounds = false
topBar.layer.shadowRadius = 8.0;
//ImageView - Back Button
let backBtn = UIButton(frame:CGRect(x: 25, y: 18, width: 18, height: 34))
let backBtnImage = UIImage(named: "back_button") as UIImage?
backBtn.setImage(backBtnImage, for: .normal)
backBtn.layer.masksToBounds = true
backBtn.addTarget(self,action:#selector(backButtonClicked),
for:.touchUpInside)
//Label - Title
let titleLabel = UILabel(frame:CGRect(x: width * 0.3, y: 13, width: width * 0.55, height: 40))
titleLabel.text = "Favorites"
titleLabel.contentMode = UIViewContentMode.center
//include all in view
topBar.addSubview(titleLabel)
topBar.addSubview(backBtn)
containerView.addSubview(topBar)
I'm trying to implement custom titleView for navigation controller with "title" and "description" labels. If I placed this titleView on first VC, it looks good. If I push second VC into navigation stack and pop it, location of the titleView is changed.
titleView's constraints:
titleLabel.translatesAutoresizingMaskIntoConstraints = false
descriptionLabel.translatesAutoresizingMaskIntoConstraints = false
titleLabel.widthAnchor.constraint(equalTo: widthAnchor).isActive = true
descriptionLabel.widthAnchor.constraint(equalTo: titleLabel.widthAnchor).isActive = true
titleLabel.topAnchor.constraint(equalTo: topAnchor).isActive = true
descriptionLabel.bottomAnchor.constraint(equalTo: bottomAnchor, constant: 2.0).isActive = true
In viewDidLoad of VC I use follow code to insert titleView:
navigationItem.titleView = BarTitleView()
navigationItem.titleView?.bounds = CGRect(x: 0, y: 0, width: view.bounds.width, height: 44)
navigationItem.titleView?.updateConstraints()
I tried to insert follow lines into viewWillAppear (second VC has different bar buttons and it can be root of problem), but nothing changes
navigationItem.titleView?.bounds = CGRect(x: 0, y: 0, width: view.bounds.width, height: 44)
navigationItem.titleView?.updateConstraints()
How can I fixed this issue?
I have created a Title and Subtitle in the Navigation bar without the need for Interface Builder and constraint modification.
My Function to create the title view looks as follows:
class func setTitle(title:String, subtitle:String) -> UIView {
let titleLabel = UILabel(frame: CGRect(x: 0, y: -8, width: 0, height: 0))
titleLabel.backgroundColor = UIColor.clear
titleLabel.textColor = UIColor.white
titleLabel.font = UIFont.boldSystemFont(ofSize: 17)
titleLabel.text = title
titleLabel.sizeToFit()
let subtitleLabel = UILabel(frame: CGRect(x: 0, y: 12, width: 0, height: 0))
subtitleLabel.backgroundColor = UIColor.clear
subtitleLabel.textColor = UIColor.white
subtitleLabel.font = UIFont.systemFont(ofSize: 12)
subtitleLabel.text = subtitle
subtitleLabel.sizeToFit()
// Fix incorrect width bug
if (subtitleLabel.frame.size.width > titleLabel.frame.size.width) {
var titleFrame = titleLabel.frame
titleFrame.size.width = subtitleLabel.frame.size.width
titleLabel.frame = titleFrame
titleLabel.textAlignment = .center
}
let titleView = UIView(frame: CGRect(x: 0, y: 0, width: titleLabel.frame.size.width, height: titleLabel.frame.size.height))
titleView.addSubview(titleLabel)
titleView.addSubview(subtitleLabel)
let widthDiff = subtitleLabel.frame.size.width - titleLabel.frame.size.width
if widthDiff < 0 {
let newX = widthDiff / 2
subtitleLabel.frame.origin.x = abs(newX)
} else {
let newX = widthDiff / 2
titleLabel.frame.origin.x = newX
}
return titleView
}
Then to use the title view in any view controller I just call this line:
self.navigationItem.titleView = Functions.Views.setTitle(title: "Title String", subtitle: "Subtitle String")
On the button click i have set UIWebView Programmatically.
if(button.tag = 1)
{
let webV:UIWebView = UIWebView(frame: CGRectMake(10, 80, (UIScreen.mainScreen().bounds.width)-20, (UIScreen.mainScreen().bounds.height)/2))
webView.loadHTMLString(html!, baseURL: nil)
let button = UIButton(frame: CGRect(x: 100, y: 100, width: 100, height: 50))
button.backgroundColor = .greenColor()
button.setTitle("Test Button", forState: .Normal)
button.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside)
webView.addSubview(button)
self.view.addSubview(webV)
}
I tried to set the button at the end of webView and i am not able to set. I tried many time still i am in progress. i want to set the button at the end of webView that i have created programmatically.
Use bounds property of the parent view to position your subview.
let bottomMargin = CGFloat(50) //Space between button and bottom of the screen
let buttonSize = CGSize(width: 100, height: 50)
let button = UIButton(frame: CGRect(
x: 0, y: 0, width: buttonSize.width, height: buttonSize.height
))
button.center = CGPoint(x: parentView.bounds.size.width / 2,
y: parentView.bounds.size.height - buttonSize.height / 2 - bottomMargin)
How can I set button at the end of View Programmatically
#IBOutlet weak var bottomView: UIView!
self.bottamView.addSubview(btnTrvalRpt) btnTrvalRpt.translatesAutoresizingMaskIntoConstraints = false btnTrvalRpt.centerXAnchor.constraint(equalTo: self.view.centerXAnchor).isActive = true btnTrvalRpt.widthAnchor.constraint(equalToConstant: 50).isActive = true btnTrvalRpt.heightAnchor.constraint(equalToConstant: 50).isActive = true btnTrvalRpt.bottomAnchor.constraint(equalTo: self.view.bottomAnchor, constant: -20).isActive = true –
