图书馆的照片不会移动和缩放

Question

在我的应用中，用户可以使用下面的代码从库中选择照片。因为我希望用户裁剪照片，所以我确保setAllowsEditing：YES。

当您选择照片时，您可以移动并缩放图像，但稍后查看图像时（selectedImage）图像将恢复为原始尺寸???

    myPicker = [[UIImagePickerController alloc] init];
    [myPicker setSourceType: UIImagePickerControllerSourceTypePhotoLibrary];
    [myPicker setToolbarHidden:NO];
    [myPicker setAllowsEditing:YES];
     myPicker.delegate = self;

    //this adds mypicker to current view
    [self presentViewController:myPicker animated:YES completion:NULL];


-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
selectedImage = [[UIImage alloc]init];

selectedImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

Answer 1

您只需使用“UIImagePickerControllerEditedImage”而不是“UIImagePickerControllerOriginalImage”。

感谢。
