# MCClipImage
[github地址](https://github.com/mancongiOS/MCClipImage)
#支持功能说明
* 裁切矩形图片
* 裁切圆形图片
* 裁切相册图片
* 裁切拍照图片
* 调整图片缩放
* 调整裁切框大小
* 图片旋转操作
#示例图
# 如何使用？
`pod 'MCClipImage'`
# 使用说明
* 引用`import MCClipImage`
* 打开编辑页面
```
let config = MCClipImageConfig()
config.clipImage = image
let vc = MCClipImageViewController()
vc.delegate = self
vc.initClipFunctionWithConfig(config)
self.present(vc, animated: true, completion: nil)
```
* 获取编辑的图片
实现MCClipImageViewControllerDelegate的代理方法
```
//点击了取消按钮
@objc optional func clipImageViewControllerDidCancel(_ viewController: MCClipImageViewController)
// 裁切完成
func clipImageViewController(_ viewController: MCClipImageViewController, didFinishClipingImage image:UIImage)
```
# 对配置类MCClipImageConfig的说明
```
public class MCClipImageConfig: NSObject {
/// 待裁切的图片
public var clipImage: UIImage?
/// 想要的裁切比例
public var clipScale: CGFloat = 2
/// 是否裁切圆形
public var isClipRound: Bool = false
/// 覆盖层的背景颜色
public var overlayBackgroundColor = UIColor.black
/// 裁切框的颜色
public var clipBoxColor = UIColor.green
/// 裁切框的宽度
public var clipBoxWidth: CGFloat = 1
/// 重设裁切比例的数组 （数组为空，隐私该按钮）
public var clipScaleType: [MCClipImageScaleType] = []
}
```
# 裁切相册/拍照图片
* 初始化
```
lazy var helper: MCPickerImageHelper = {
let helper = MCPickerImageHelper()
return helper
}()
```
**MCPickerImageHelper，如果声明为局部对象的话，走完就被销毁了。但是MCPickerImageHelper对象又作为n内部pickerViewController的代理执行者，执行者没了，所以就不响应pickerViewController的代理方法。 所以一定不能让MCPickerImageHelper对象被销毁，要么懒加载该对象要么成为全局的。**
* 开启
```
// 开启相册
helper.openPhotoLibrary(self)
// 开启拍照
helper.openCamera(self)
```
* 实现代理方法
```
@objc optional func pickerImageHelperDidCancel(_ picker: MCPickerImageHelper)
func pickerImageHelper(_ picker: MCPickerImageHelper, didFinishPickImage image:UIImage)
```
