如何从UIImage获取文件路径？ [英] How can I get the file path from a UIImage?

问题描述

通常情况相反，您使用路径显示图像。我想知道如果你已经拥有图像，是否可以获得路径。

Usually it's the other way around, you use the path to display the image. I was wondering if you can get the path if you already have the image.

推荐答案

如果你已经拥有图片，即已添加文件到你的资源，你可以使用它来获取文件路径;

if you already have the image i.e. have added the file to your resources, you can use this to get the file path;

NSString *string = [[NSBundle mainBundle] pathForResource:@"IMAGE_FILE_NAME" ofType:@"jpg"]; // or ofType:@"png", etc.
