Swift Extension UIImage+SP(源码)

效果

使用

import UIKit
import SnapKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    
        let image_0 = UIImage(named: "2")!
        print(image_0.sp.sizeAsBytes)  // 输出图片的 Bytes 大小
        print(image_0.sp.sizeAsKB)  // 输出图片的 KB 大小
        print(image_0.sp.sizeAsMB)  // 输出图片的 MB 大小
        
        let imageFromURL = UIImage(urlStr: "https://example.com/image.jpg")
        let coloredImage = UIImage.initWith(color: .red, size: CGSize(width: 100, height: 100))
        
        let image_1 = UIImage(named: "example")!
        let croppedImage = image_1.sp.dealWithCrop(bound: CGRect(x: 0, y: 0, width: 100, height: 100))
        let roundedImage = image_1.sp.dealWithRound(radius: 10)
        let resizedImage = image_1.sp.reSize(size: CGSize(width: 200, height: 200))
        
        let image_2 = UIImage(named: "example")!
        if let compressedData = image_2.sp.compress(rate: 0.5) {
          // 使用压缩后的数据
        }
        
        let imageTarget: SPImageTarget = "example.jpg"
        let image = UIImage.deal(original: imageTarget)
    }
}
