swift ios 获取 imageView 的文件路径

Question

我已经复制了文件绝对路径并粘贴到模拟器浏览器中，图像可以打开。但 fileExists 失败，我不知道为什么......任何人都可以帮忙

 let defaultImage = "302C3FA1-E4E1-4CD8-B6DF-2FF4E4E24C11.jpeg"

loadImage(at: defaultImage)

 func fileExists(at path: String) -> Bool {
        return FileManager.default.fileExists(atPath: path)
    }

    func loadImage(at path: String) -> UIImage? {
        let tempPath = URL(fileURLWithPath: NSTemporaryDirectory(), isDirectory: true)
        let imagePath = "\(tempPath)\(path.trimmingCharacters(in: .whitespacesAndNewlines))"
        guard fileExists(at: imagePath) else { return nil }
        guard let image = UIImage(contentsOfFile: imagePath) else { return nil }
        return image
    }

您需要拆分文件名和扩展文件名。

如果您使用主包。您可以遵循此代码

let stringPath = Bundle.main.path(forResource: "your_filename", ofType: "txt")

let urlPath = Bundle.main.url(forResource: "your_filename", withExtension: "txt")

，也可以使用我的代码。

func readConfigFromBundle(fileExtension: String) -> TCBConfigure? {
    let bundle = Bundle.main
    
    if let resPath = bundle.resourcePath {
        do {
            let dirContents = try FileManager.default.contentsOfDirectory(atPath: resPath)
            let filteredFiles = dirContents.filter { $0.contains(fileExtension) }
            for fileName in filteredFiles {
                let sourceURL = bundle.bundleURL.appendingPathComponent(fileName)
                let data: NSData? = NSData.init(contentsOf: sourceURL)
                if let fileData = data {
                    // implement your logic
                }
            }
        } catch {
            // implement when error
        }
    }
    return nil
}
