Question

我想获取我从iphone库中选择的所有图像细节喜欢

图片名称
图片路径
图片类型
图片尺寸
图片ID

我选择了像

   picker1 = [[UIImagePickerController alloc]init];
    picker1.delegate = self;
    picker1.allowsEditing= YES;
    //picker1.showsCameraControls = YES;
    picker1.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentModalViewController:picker1 animated:YES];
    [picker1 release];

然后选择图像

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info;
{
    isImage = TRUE;

    image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    sendimageview.image=image;
    appDelegate.mediabuttonpress=TRUE;
}

并且对于路径我尝试了这个但没有得到正确的路径

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
 NSString *strPath= [paths objectAtIndex:0];
 strPath = [strPath stringByAppendingPathComponent:imageName];
 NSLog(@"*******Path %@",strPath);

需要帮助......

谢谢..

Answer 1

我认为你必须使用ALAsset类，因为我不确定，UIImage提供你需要的所有信息（尤其是GPS信息）。

Answer 2

您无法从图书馆获取图像的“真实”路径，即使您可以获取它也无法访问。

Answer 3

试试这个

   - (void)imagePickerController:(UIImagePickerController *)picker 
didFinishPickingMediaWithInfo:(NSDictionary *)info {
    NSURL *assetURL = [info objectForKey:UIImagePickerControllerReferenceURL];

  ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];

  [library assetForURL:assetURL resultBlock:^(ALAsset *asset) {
   ALAssetRepresentation *representation = [asset defaultRepresentation];
   metadataDict = [[representation metadata] retain]; 
   NSLog(@"%@",metadataDict);


  } failureBlock:^(NSError *error) {
   NSLog(@"%@",[error description]);
  }];
[library release];
}

您还必须使用__block标识符声明它。

       __block NSDictionary *metaDataDict;
