[英]Trying to save image to Photo album with custom name in iOS
I have an iOS application where I am saving an image to my photos folder to my iPad.我有一个 iOS 应用程序,我将图像保存到我的 iPad 的照片文件夹中。 However, what I would like to do is store the image with a custom name (eg using the date and time stamp for when the image was actually captured), so that it would be easier for it to be retrieved in the future.
但是,我想要做的是使用自定义名称存储图像(例如,使用实际捕获图像的日期和时间戳),以便将来更容易检索它。
My code at the moment for storing my images is as follows:我目前用于存储图像的代码如下:
- (IBAction)imageCapture:(id)sender {
UIImage *myImage = [_imageView currentImage];
UIImageWriteToSavedPhotosAlbum(myImage, nil, nil, nil);
}
I am able to store my image, but how do I name the image prior to storing it (eg "082620131100am.png"?我可以存储我的图像,但是如何在存储图像之前命名图像(例如“082620131100am.png”?
Since you cannot override any image/video in the user's photo library, you will not be able to give the the file a specific filename.由于您无法覆盖用户照片库中的任何图像/视频,因此您将无法为该文件指定特定的文件名。
You can add some metadata to your image if you use the method: writeImageDataToSavedPhotosAlbum:metadata:completionBlock:
, but you will not be able to set the filename.如果您使用以下方法,您可以向图像添加一些元数据:
writeImageDataToSavedPhotosAlbum:metadata:completionBlock:
,但您将无法设置文件名。
