我想通過使用徽標(biāo)圖像（而不是純文本）作為導(dǎo)航欄的標(biāo)題來自定義應(yīng)用程序的外觀。當(dāng)我使用此代碼let logo = UIImage(named: "logo.png")self.navigationItem.titleView = logo;我收到錯誤“ UIImage無法轉(zhuǎn)換為UIView”。如何正確執(zhí)行此操作？

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

我用這個(gè) 它適用于iOS 8
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let image = UIImage(named: "YOURIMAGE")
navigationItem.titleView = UIImageView(image: image)
}
這是一個(gè)示例，您如何使用CGRect做到這一點(diǎn)。
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
}
希望這會有所幫助。

對于Swift 4，您可以調(diào)整imageView的大小
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
