快速接入

将 JHImagePicker 文件夹拖入项目即可

使用步骤：

单独使用图片选择器

        _ = self.jh_presentPhotoVC(1, completeHandler: { items in
            print("当前选中的图片数组", items)
            if let first = items.first {
                print("获取回调图片：",first.image!)
                
                first.originalImage({ (image) in
                    self.imageView.image = image
                    print("获取原图：",image)
                })
                
            }
        })

同时使用系统相机和图片选择器

1.声明

var imagePickerController:JHImagePicker?

2.初始化

//初始化方法一
//        imagePickerController = JHImagePicker()
//初始化方法一的补充设置(若需要缓存时才设置)
//设置是否缓存(默认为false)
//        imagePickerController?.isCaches = true
//设置缓存id（当需要缓存时才设置）
//        imagePickerController?.identifier = "xx"

//初始化方法二
imagePickerController = JHImagePicker(isCaches: true, identifier: "abc")

3.设置代理 JHImagePickerDelegate

imagePickerController?.delegate = self

选取图片来自相册注意使用[weak self] 防止强引用

    let photoAction = UIAlertAction(title: "从手机相册选择", style: .default) { (action) in
        _ = self.jh_presentPhotoVC(1, completeHandler: { items in
            print("当前选中的图片数组", items)
            if let first = items.first {
                print("获取回调图片：",first.image!)
                
                first.originalImage({ (image) in
                    self.imageView.image = image
                    print("获取原图：",image)
                })
                
            }
        })
    }

选取图片来自相机注意使用[weak self] 防止强引用

self.imagePickerController?.selectImageFromCameraSuccess({[weak self](imagePickerController) in
    if let strongSelf = self {
        strongSelf.presentViewController(imagePickerController, animated: true, completion: nil)
    }
}, Fail: {
    //SVProgressHUD.showErrorWithStatus("无法获取相机权限")
})

以下方法跟系统相机拍照有关:

5.1当未设置缓存或缓存identifier为空时返回该方法

func selectImageFinished(image: UIImage) {
    imageView.image = image
    self.dismissViewControllerAnimated(true, completion: nil)
}

5.2当设置了缓存，且输入缓存identifier时返回该方法(未设置缓存时可以不实现)

func selectImageFinishedAndCaches(image: UIImage, cachesIdentifier: String, isCachesSuccess: Bool) {
    if isCachesSuccess == true {
        imageView.image = image
    }
    self.dismissViewControllerAnimated(true, completion: nil)
}

6.根据identifier读取缓存图片(拍照结果)

let image = self.imagePickerController?.readImageFromCaches("abc")
if image?.accessibilityIdentifier != "jhSurprise.jpg" {
    imageView.image = image
}else {
    print("读取缓存照片失败,请检查图片identifier是否存在")
}

7.删除指定identifier的缓存图片(删除id：abc)

self.imagePickerController?.removeCachesPictureForIdentifier("abc")

删除全部缓存图片

if self.imagePickerController?.removeCachesPictures() == true {
    print("删除全部缓存图片成功")
}

仿微信预览模式

特别提醒

如果相簿的名字显示为英文，则需要添加为项目添加国际化。

在 Project -> Info -> Localizations 下，添加 Chinese(Simplified) 即可。
若不想显示数据为 0 的相册，请使用 JHImageListVC.swift 中:

	if assetsFetchResult.count < 1 { continue }
