iOS 手動安裝第三方庫 Objective-C to Swift

記錄一次使用 TimOliver/TOCropViewController (opens new window), 手動安裝Swift Projet

---

一開始新建一個Project

下載 TimOliver/TOCropViewController (opens new window)

git clone https://github.com/TimOliver/TOCropViewController.git

目錄大概是這樣

根據作者的README (opens new window), swift project需要同時使用Objective-C/TOCropViewController和Swift/CropViewController

All of the necessary source and resource files for TOCropViewController are in Objective-C/TOCropViewController, and all of the necessary Swift files are in Swift/CropViewController.

For Objective-C projects, copy just the TOCropViewController directory to your Xcode project. For Swift projects, copy both TOCropViewController and CropViewController to your project.

在剛剛新建的Project 點擊 Add Files to "xxx"...

先選擇TOCropViewController/Objective-C/TOCropViewController, 記得點擊Create groups

可以看到剛點加入的檔䅁會黃色，如果選了Create folder references會顯示藍色

再將TOCropViewController/Swift/CropViewController的檔案加入TOCropViewController

注意⚠️: 要把info.plist刪除，否則會有錯誤

接下來是關鍵的一步建立{project name}-Bridging-Header.h

//{project name}-Bridging-Header.h
#import "TOCropViewController.h" // add

要在設定加入

測試

加入一張相片用作測試

加一個Button

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }

    @IBAction func click(_ sender: Any) {
        let image: UIImage = UIImage(named: "test-image")!
        let cropViewController = CropViewController(image: image)
        cropViewController.delegate = self
        present(cropViewController, animated: true, completion: nil)
    }
}

extension ViewController: CropViewControllerDelegate {
    func cropViewController(_ cropViewController: CropViewController, didCropToImage image: UIImage, withRect cropRect: CGRect, angle: Int) {
        print(image)
    }
}

成功取得正確的結果
