BSimagepicker进入imageview

Question

有没有办法将多个选定的图像（使用BSimagePicker）添加到Imageview中？

Imageview代码

@IBAction func showImagePicker(sender: UIButton) {
    let vc = BSImagePickerViewController()
    vc.maxNumberOfSelections = 10

    bs_presentImagePickerController(vc, animated: true,
        select: { (asset: PHAsset) -> Void in
            print("Selected: \(asset)")
        }, deselect: { (asset: PHAsset) -> Void in
            print("Deselected: \(asset)")
        }, cancel: { (assets: [PHAsset]) -> Void in
            print("Cancel: \(assets)")
        }, finish: { (assets: [PHAsset]) -> Void in
            print("Finish: \(assets)")
        }, completion: nil)
}

要将资产数组转换为图像数组，请将以下代码添加到BSImagePicker的方法中。

首先创建全局资产数组。我在这里创建了

var SelectedAssets = [PHAsset]()

然后调用BSImagepicker的方法添加以下代码。

bs_presentImagePickerController(vc, animated: true,
                                    select: { (asset: PHAsset) -> Void in
                                        print("Selected: \(asset)")
        }, deselect: { (asset: PHAsset) -> Void in
            print("Deselected: \(asset)")
        }, cancel: { (assets: [PHAsset]) -> Void in
            print("Cancel: \(assets)")
        }, finish: { (assets: [PHAsset]) -> Void in
            print("Finish: \(assets)")
            print(assets.count)
            for i in 0..<assets.count
            {
                self.SelectedAssets.append(assets[i])
                print(self.SelectedAssets)
            }
        }, completion: nil)

创建一个将您的资产数组转换为图像数组的方法。我在这里创建了一个方法。

func getAllImages() -> Void {

    print("get all images method called here")
    if SelectedAssets.count != 0{
        for i in 0..<SelectedAssets.count{
            let manager = PHImageManager.defaultManager()
            let option = PHImageRequestOptions()
            var thumbnail = UIImage()
            option.synchronous = true
            manager.requestImageForAsset(SelectedAssets[i], targetSize: CGSize(width: 200, height: 200), contentMode: .AspectFill, options: option, resultHandler: {(result, info)->Void in
                thumbnail = result!
            })
            self.PhotoArray.append(thumbnail)
        }
    }
    ImagesCollectionView.reloadData()
}

在上面的方法中，我使用“集合视图”显示所有选定的图像。

现在执行视图中的选择器方法将在延迟后执行get all images方法。如下：

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)

    self.performSelector(#selector(ViewController.getAllImages), withObject: nil, afterDelay: 0.5)
}

那就是它你会得到所选择的图像......希望它能帮助你......
