回答1:

You can try this code to access an Image returned from the picker

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

    [picker dismissModalViewControllerAnimated:YES];

    UIImage* originalImage = nil;
    originalImage = [info objectForKey:UIImagePickerControllerEditedImage];
    if(originalImage==nil)
    {
        originalImage = [info objectForKey:UIImagePickerControllerOriginalImage];
    }
    if(originalImage==nil)
    {
        originalImage = [info objectForKey:UIImagePickerControllerCropRect];
    }
  //At this point you have the selected image in originalImage
    [self saveImageToDocumentDirectory:originalImage];
}

Try

imageview.image = (UIImage*) [info objectForKey:UIImagePickerControllerOriginalImage];

回答3:

For Swift (3.0), the following will safely unwrap the image, and if it is valid, then assign it to your imageView.

guard let image = info[UIImagePickerControllerOriginalImage] as? UIImage else { return }
imageView.image = image

just try this

imageview.image = [info objectForKey:UIImagePickerControllerOriginalImage];
