相册多选.gif

具体看代码就行,写这个相册多选以及图片浏览器有很多细节需要注意的,我也用了不少心血.想了解的看代码.我就说说用法

    let album = JDAlbumGroupController()

    album.selectImgsClosure1 = { (assets: [PHAsset]) in
        for index in 0..

typealias ImgCallBackType = (UIImage?)->()

//获取缩略图 缩略图大小需要自己指定
private func getLitImage(asset: PHAsset,callback: @escaping ImgCallBackType){
    PHImageManager.default().requestImage(for: asset,
                                          targetSize: CGSize(width: 100, height: 100) , contentMode: .aspectFill,
                                          options: nil, resultHandler: {
                                            (image, _: [AnyHashable : Any]?) in
                                            if image != nil{
                                                callback(image)
                                            }
                                            
    })
    
}


//获取原图
private func getOrangeImage(asset: PHAsset,callback: @escaping ImgCallBackType){
    //获取原图
    PHImageManager.default().requestImage(for: asset,
                                          targetSize: PHImageManagerMaximumSize , contentMode: .aspectFill,
                                          options: nil, resultHandler: {
                                            (image, _: [AnyHashable : Any]?) in
                                            if image != nil{
                                                callback(image)
                                            }
                                            
    })
    
}
