如何在导航栏标题中调整图像大小

Question

我正在尝试调整图像大小，使其适合导航标题。我给它高度和重量，但看起来仍然很大

这是我的代码：

equal = [(i, j) for i in range (len(l1)) for j in range(len(l2)) if l1[i] == l2[j]]
if equal:
     print("Overlapped")
else:
     print("Separated")  

当我手动将图片编辑为较小尺寸时，它将失去分辨率。 如何使用代码将其设置为58:33？

Answer 1

我认为您的imageViews大小取决于imageView的intrinsicContentSize属性。

您可以尝试imageview.invalidateIntrinsicContentSize()

Answer 2

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
}
