제목에 대한 UIImage가있는 탐색 모음

제목에 대한 UIImage가있는 탐색 모음

---

일반 텍스트 대신 로고 이미지를 탐색 모음의 제목으로 사용하여 내 앱의 모양을 사용자 지정하고 싶습니다. 이 코드를 사용할 때

let logo = UIImage(named: "logo.png")
self.navigationItem.titleView = logo;

"UIImage는 UIView로 변환 할 수 없습니다"라는 오류가 발생합니다. 이 작업을 올바르게 수행하려면 어떻게해야합니까?

---

안에 넣어 UIImageView

let logo = UIImage(named: "logo.png")
let imageView = UIImageView(image:logo)
self.navigationItem.titleView = imageView

나는 이것을 사용한다. iOS 8에서 작동합니다.

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    let image = UIImage(named: "YOURIMAGE")
    navigationItem.titleView = UIImageView(image: image)
}

다음은 CGRect로 수행 할 수있는 방법의 예입니다.

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 38, height: 38))
    imageView.contentMode = .ScaleAspectFit
    let image = UIImage(named: "YOURIMAGE")
    imageView.image = image
    navigationItem.titleView = imageView
}

이것이 도움이되기를 바랍니다.

신속한 4의 경우 imageView 크기를 조정할 수 있습니다.

 let logoContainer = UIView(frame: CGRect(x: 0, y: 0, width: 270, height: 30))

 let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 270, height: 30))
 imageView.contentMode = .scaleAspectFit
 let image = UIImage(named: "your_image")
 imageView.image = image
 logoContainer.addSubview(imageView)
 navigationItem.titleView = logoContainer

---

사용자 지정 UINavigationItem을 사용할 수 있으므로 Main.storyboard에서 "Navigation Item"을 YourCustomClass로 변경하기 만하면됩니다.

Swift 3에서

class FixedImageNavigationItem: UINavigationItem {

private let fixedImage : UIImage = UIImage(named: "your-header-logo.png")!
private let imageView : UIImageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 50, height: 37.5))

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    imageView.contentMode = .scaleAspectFit
    imageView.image = fixedImage
    self.titleView = imageView

}

}

위의 @Jack의 대답을 시도했지만 로고가 나타나지만 이미지가 전체 탐색 모음을 차지했습니다. 나는 그것이 맞기를 원했습니다.

스위프트 4, Xcode 9.2

1. 탐색 컨트롤러 UIImage에 값을 할당합니다. 프레임과 이미지 크기를 나누어 크기를 조정합니다.

func addNavBarImage() {

        let navController = navigationController!

        let image = UIImage(named: "logo-signIn6.png") //Your logo url here
        let imageView = UIImageView(image: image)

        let bannerWidth = navController.navigationBar.frame.size.width
        let bannerHeight = navController.navigationBar.frame.size.height

        let bannerX = bannerWidth / 2 - (image?.size.width)! / 2
        let bannerY = bannerHeight / 2 - (image?.size.height)! / 2

        imageView.frame = CGRect(x: bannerX, y: bannerY, width: bannerWidth, height: bannerHeight)
        imageView.contentMode = .scaleAspectFit

        navigationItem.titleView = imageView
    }

2. 바로 아래에 기능 추가 viewDidLoad()

       addNavBarImage() 
   

이미지 자산에 대한 참고. 업로드하기 전에 가장자리가 잘리지 않고 여분의 여백으로 로고를 조정했습니다.

이것은 2015 년 9 월에 저에게 효과적이었습니다.

// 1
    var nav = self.navigationController?.navigationBar
    // 2 set the style 
    nav?.barStyle = UIBarStyle.Black
    nav?.tintColor = UIColor.yellowColor()
    // 3
    let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
    imageView.contentMode = .ScaleAspectFit
    // 4
    let image = UIImage(named: "logo.png")
    imageView.image = image
    // 5
    navigationItem.titleView = imageView

다음은 Swift 4.2의 편리한 기능으로 제목 텍스트가있는 이미지를 보여줍니다.

override func viewDidLoad() {

    super.viewDidLoad()

    //Sets the navigation title with text and image
    self.navigationItem.titleView = navTitleWithImageAndText(titleText: "Dean Stanley", imageName: "online")
}

func navTitleWithImageAndText(titleText: String, imageName: String) -> UIView {

    // Creates a new UIView
    let titleView = UIView()

    // Creates a new text label
    let label = UILabel()
    label.text = titleText
    label.sizeToFit()
    label.center = titleView.center
    label.textAlignment = NSTextAlignment.center

    // Creates the image view
    let image = UIImageView()
    image.image = UIImage(named: imageName)

    // Maintains the image's aspect ratio:
    let imageAspect = image.image!.size.width / image.image!.size.height

    // Sets the image frame so that it's immediately before the text:
    let imageX = label.frame.origin.x - label.frame.size.height * imageAspect
    let imageY = label.frame.origin.y

    let imageWidth = label.frame.size.height * imageAspect
    let imageHeight = label.frame.size.height

    image.frame = CGRect(x: imageX, y: imageY, width: imageWidth, height: imageHeight)

    image.contentMode = UIView.ContentMode.scaleAspectFit

    // Adds both the label and image view to the titleView
    titleView.addSubview(label)
    titleView.addSubview(image)

    // Sets the titleView frame to fit within the UINavigation Title
    titleView.sizeToFit()

    return titleView

}

자동 레이아웃을 사용하고 탐색 모음에 영구적으로 고정 된 이미지를 원하는 경우 각 화면에 애니메이션이 적용되지 않는 경우이 솔루션이 잘 작동합니다.

class CustomTitleNavigationController: UINavigationController {

override func viewDidLoad() {
    super.viewDidLoad()

    let logo = UIImage(named: "MyHeaderImage")

    let imageView = UIImageView(image:logo)
    imageView.contentMode = .scaleAspectFit
    imageView.translatesAutoresizingMaskIntoConstraints = false

    navigationBar.addSubview(imageView)

    navigationBar.addConstraint (navigationBar.leftAnchor.constraint(equalTo: imageView.leftAnchor, constant: 0))
    navigationBar.addConstraint (navigationBar.rightAnchor.constraint(equalTo: imageView.rightAnchor, constant: 0))
    navigationBar.addConstraint (navigationBar.topAnchor.constraint(equalTo: imageView.topAnchor, constant: 0))
    navigationBar.addConstraint (navigationBar.bottomAnchor.constraint(equalTo: imageView.bottomAnchor, constant: 0))
}

시도하고 체크 아웃하자

let image = UIImage(named: "Navbar_bg.png")
navigationItem.titleView = UIImageView(image: image)
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
imageView.contentMode = .ScaleAspectFit

나는 이것을 iOS 10 및 iOS 11 용으로 작성했으며 나를 위해 일했습니다.

extension UINavigationBar {
    func setupNavigationBar() {
        let titleImageWidth = frame.size.width * 0.32
        let titleImageHeight = frame.size.height * 0.64
        var navigationBarIconimageView = UIImageView()
        if #available(iOS 11.0, *) {
            navigationBarIconimageView.widthAnchor.constraint(equalToConstant: titleImageWidth).isActive = true
            navigationBarIconimageView.heightAnchor.constraint(equalToConstant: titleImageHeight).isActive = true
        } else {
            navigationBarIconimageView = UIImageView(frame: CGRect(x: 0, y: 0, width: titleImageWidth, height: titleImageHeight))
        }
        navigationBarIconimageView.contentMode = .scaleAspectFit
        navigationBarIconimageView.image = UIImage(named: "image")
        topItem?.titleView = navigationBarIconimageView
    }
}

Swift 5.1, Xcode 11

때로는 이미지가 고해상도이면 imageView가 중앙에서 이동합니다.이 방법을 사용하는 것이 좋습니다.

  lazy var navigationTitleImageView = UIImageView()

  override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    self.setNavigationBar()

    self.navigationTitleImageView.image = logo
    self.navigationTitleImageView.contentMode = .scaleAspectFit

    self.navigationTitleImageView.translatesAutoresizingMaskIntoConstraints = false

    if let navC = self.navigationController{
        navC.navigationBar.addSubview(self.navigationTitleImageView)
        self.navigationTitleImageView.centerXAnchor.constraint(equalTo: navC.navigationBar.centerXAnchor).isActive = true
        self.navigationTitleImageView.centerYAnchor.constraint(equalTo: navC.navigationBar.centerYAnchor, constant: 0).isActive = true
        self.navigationTitleImageView.widthAnchor.constraint(equalTo: navC.navigationBar.widthAnchor, multiplier: 0.2).isActive = true
        self.navigationTitleImageView.heightAnchor.constraint(equalTo: navC.navigationBar.widthAnchor, multiplier: 0.088).isActive = true
    }
}

및 viewWillDisappear ()

  override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    self.navigationTitleImageView.removeFromSuperview()
}

또는 이미지 크기를 줄입니다.

스위프트 4에서 작동합니다 (정사각형 이미지 40x40).

let imageView = UIImageView()
        imageView.frame.size.width = 40
        imageView.frame.size.height = 40
        imageView.contentMode = .scaleAspectFit
        let image = UIImage(named: "YOUR_IMAGE_NAME")
        imageView.image = image
        navigationItem.titleView = imageView

다른 조치를 원하면 시도하십시오

let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 50, height: 100.5)))
            imageView.contentMode = .scaleAspectFit
            let image = UIImage(named: "YOUR_IMAGE_NAME")
            imageView.image = image
            navigationItem.titleView = imageView

나는 그것이 당신에게 도움이되기를 바랍니다. 그것은 나를 위해 작동합니다.

이것은 나를 위해 일했습니다 ... 해보십시오

 let image : UIImage = UIImage(named: "LogoName")
    let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 25, height: 25))
    imageView.contentMode = .scaleAspectFit
    imageView.image = image
    navigationItem.titleView = imageView

---

    let imageView = UIImageView(frame: (CGRect(x: 0, y: 0, width: 40, height: 
    40)))
    imageView.contentMode = .scaleAspectFit
    let image = UIImage (named: "logo") // logo is your NPG asset 
    imageView.image = image
    self.navigationItem.titleView = imageView
