我正在尝试获取图像和视频的地理位置,虽然图像位置是通过获取的。
PHAsset.fetchAssetsWithALAssetURLs([imageUrl], options: opts).
当我在视频中使用下面相同的代码时,返回0。
PHAsset.fetchAssetsWithALAssetURLs([videoUrl], options: opts)
最佳答案
这是在iOS 8上测试的,适用于视频,所以对照片也应该同样适用,只需稍作调整。
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSURL *videoUrl = (NSURL *)[info objectForKey:UIImagePickerControllerMediaURL];
NSString *moviePath = [videoUrl path];
if ( UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(moviePath) ) {
ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];
[assetLibrary assetForURL:[info objectForKey:UIImagePickerControllerReferenceURL] resultBlock:^(ALAsset *asset) {
CLLocation *location = [asset valueForProperty:ALAssetPropertyLocation];
NSLog(@"Location Meta: %@", location);
} failureBlock:^(NSError *error) {
NSLog(@"Video Date Error: %@", error);
}];
}
}
