Answer 1

Use this Code,

- (void)imagePickerController:(UIImagePickerController *)photoPicker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSString *mediaType;
    mediaType = [info objectForKey:UIImagePickerControllerMediaType];


    if ([mediaType isEqualToString:(NSString *)kUTTypeImage ])
    {

        UIImage * image = (UIImage*) [info objectForKey:UIImagePickerControllerEditedImage];
        imageAddView.image  = [UIImage squareImageWithImage:image scaledToSize:CGSizeMake(640, 640)];

        [photoPicker dismissViewControllerAnimated:YES completion:NULL];

    }

}

hope its helpful

Answer 2

your code should be like,

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

 UIImage *image=info[UIImagePickerControllerEditedImage];
 [self emailImage:image];

[self dismissViewControllerAnimated:YES completion:^
 { 
     //perform anything after dismissing image picker controller
 }
 ];
 }

Hope this will help :)
