ImagePickerController crash presentViewController when called in UIStoryboardPopoverSegue - objective-c

Question

I have a viewcontroller called via UIStoryboardPopoverSegue and inside there is a button to call the imagePickerController, it's ok for the first call but the second time it crash.
The code is use is ok when it is not through UIStoryboardPopoverSegue.
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image=[info objectForKey:UIImagePickerControllerOriginalImage];
UIImageWriteToSavedPhotosAlbum (image, nil, nil , nil);
[self dismissViewControllerAnimated:YES completion:nil];
}
-(IBAction)takephoto:(id)sender
{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
self.imagePicker.delegate=self;
self.imagePicker.sourceType=UIImagePickerControllerSourceTypeCamera;
[self presentViewController:imagePicker animated:YES completion:nil];
}
}
- (void)viewDidLoad
{
[super viewDidLoad];
if (!self.imagePicker)
{
self.imagePicker = [[UIImagePickerController alloc] init];
}
}
I enabled NSZobmbie to show any log that can help me tracing it.

Your UIImagePickerController is released and then attempted to be accessed later - so crashes!
To fix it, make the UIImagePickerController a strongly referenced property of the owning instance:
#property (strong, nonatomic) UIImagePickerController *imagePicker;
initialise it once:
if (!self.imagePicker) self.imagePicker = [[UIImagePickerController alloc] init];
and use:
[self.imagePicker doStuff]
for access.
That should solve it.
EDIT
if ([[segue identifier]isEqualToString:#"tcwindshield"]) {
self.ips = [segue destinationViewController];
self.ips.delegate = self
self.ips.strStatValue=#"WindShield";
}
