Crash when choosing from the iphone photo album using monotouch
My 开发者_C百科application crashes completely (fatal error), showing the entire stacktrace and "Error connecting stdout and stderr. The weird thing is though, if I do not shut down the iPhone simulator, and I go through the workflow on my app a second time, there is no crash.
I tried both PhotoLibrary and SavedPhotosAlbum;
When picker.SourceType = UIImagePickerControllerSourceType.PhotoLibrary
, everything works fine until it brings up the photo library. When you click the photo library to see the images inside, this is when the crash occurs.
When picker.SourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
, the album loads fine, and I can even select an image. After I select an image, I can edit the image, etc...Once I'm done and hit Choose. It crashes.
Again, after it crashes, I can go through the workflow and it gets through just fine.
This is very strange. Any ideas?
Thanks.
I had this exact same problem; it turns out the ImagePickerController object was being garbage collected, are you declaring the property inside of a method (e.g. a button touch event?). I found if I declared the property at the start of the class then it solved this problem. Code sample:
UIImagePickerController picker;
//snip
void HandlePhotoBtnTouchUpInside(object sender, EventArgs e)
{
picker = new UIImagePickerController();
ImagePickerDelegate imgDel = new ImagePickerDelegate();
picker.Delegate = imgDel;
picker.SourceType = UIImagePickerControllerSourceType.PhotoLibrary;
PresentModalViewController(imagePicker, true);
}
The ImagePickerDelegate Class is pretty simple, I've only overridden the FinishedPickingMedia
method.
