Ios 在CollectionView中将手机图库中的图像显示到手机中

单击单元格，我可以打开图库，我需要保存按下的图像并将其显示在单元格中，是否有帮助？

您需要使用“资产库”框架从设备获取图像

您可以通过以下链接找到解决方案- 在iOS 9.0中不推荐使用AssetLibrary

所以使用了新的“照片”框架

下面是使用新框架的swift代码

 func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
    imagePicker.allowsEditing =  false
    imagePicker.sourceType = .PhotoLibrary
    self.presentViewController(imagePicker, animated: true, completion: nil)



}
 //  func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
   // picker .dismissViewControllerAnimated(true, completion: nil)
 // }
       func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {


    }

您需要使用以下代码包括标题-“导入照片”

var pickedImage=UIImageView（）

PickeImage=info[UIImagePickerControllerOriginalImage]作为？UIImage

CollectionView的in-cellForRowAtIndexPath方法

---

cell.imageview.image=pickedImage

swift中是否有链接？因为这是目标c

func getAllImages() {

    let imgManager     : PHImageManager!        = PHImageManager.defaultManager()
    let photosArray    : NSMutableArray!        = NSMutableArray()
    let requestOptions : PHImageRequestOptions! = PHImageRequestOptions()
    let fetchOptions   : PHFetchOptions!        = PHFetchOptions()

    requestOptions.synchronous = true

    if let fetchResult: PHFetchResult = PHAsset.fetchAssetsWithMediaType(PHAssetMediaType.Image, options: fetchOptions) {

        if fetchResult.count > 0 {

            for i in 0...fetchResult.count {
                imgManager.requestImageForAsset(fetchResult.objectAtIndex(i) as! PHAsset, targetSize: view.frame.size, contentMode: PHImageContentMode.AspectFill, options: requestOptions, resultHandler: { (image, _) in
                    photosArray.addObject(image!)
                });
            }
        }
    }
}
