UIImage在iPhone上保存带文件名的图像 [英] UIImage Saving image with file name on the iPhone

问题描述

如何将图像（如使用UIImageWriteToSavedPhotosAlbum（）方法）与我选择的文件名保存到private / var文件夹中？

How can I save an image (like using UIImageWriteToSavedPhotosAlbum() method) with a filename of my choice to the private/var folder?

推荐答案

肯尼，你有答案！为了说明，我总是认为代码更有用。

Kenny, you had the answer! For illustration I always think code is more helpful.

//I do this in the didFinishPickingImage:(UIImage *)img method

NSData* imageData = UIImageJPEGRepresentation(img, 1.0);


//save to the default 100Apple(Camera Roll) folder.   

[imageData writeToFile:@"/private/var/mobile/Media/DCIM/100APPLE/customImageFilename.jpg" atomically:NO];
