如何获取PHAsset图片的路径或目录？

我遇到了@diegomen写的答案here，但当我尝试selectedAssets[0].PHAsset.getURL()时，它要求输入参数，但@diegomen表示它不需要评论中的参数。

我申请错了吗？

或者是否有其他方式从PHAsset获取图片路径？

注意：我在@Clay中找到了另一个解决方案here，但它似乎不是一个很好的做法。

Answer 1

如果您已将图像存储在本地文件路径中，并且想从PHAsset图像地址中检索图像文件路径，则使用此功能：

[asset requestContentEditingInputWithOptions:[PHContentEditingInputRequestOptions new] completionHandler:^(PHContentEditingInput *contentEditingInput, NSDictionary *info) {
    NSURL *imageURL = contentEditingInput.fullSizeImageURL;
    }];

asset = PHAsset * asset

您应该将图像存储到本地文件。之后你会有文件网址。

class DoubleListInterface

      @return True if the list is empty; otherwise returns false. */
    virtual bool isEmpty() const = 0;

    /** Gets the current number of entries in this list.
      @return The integer number of entries currently in the list. */
    virtual int getLength() const = 0;

    /** Inserts an entry into this list at the front.
