如何在物镜c中获取照片创建日期 [英] How to get photo creation date in objective c

问题描述

我正在尝试从iPhone的图片库中选择图片时获取图片拍摄日期.我正在使用下面的代码来做同样的事情.

I am trying to get picture taken date while choosing picture from Photo Library in iPhone. I am using below code to do the same.

NSDictionary* fileAttribs = [[NSFileManager defaultManager] attributesOfItemAtPath:path error:nil];
NSDate *result = [fileAttribs fileCreationDate]; //or fileModificationDate

但是它显示的是当前日期和时间.

But it is showing current date and time.

从照片库中选择图片时，有什么方法可以获取拍摄日期.

Is there any way to get picture taken date while choosing picture from Photo library.

推荐答案

您可以使用寻找密钥ALAssetPropertyDate

编辑，完整代码:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    NSURL *url = [info objectForKey:@"UIImagePickerControllerReferenceURL"];

    ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc] init];
    [assetslibrary assetForURL:url
                   resultBlock:^(ALAsset *asset) {
                       NSDate *myDate = [asset valueForProperty:ALAssetPropertyDate];
                       NSLog(@"Date: %@", myDate);
                   } failureBlock:^(NSError *error) {
                       NSLog(@"Error");
                   }];

    [picker dismissViewControllerAnimated:YES completion:nil];

}
