Question

I am using UIImagePickerView controller to take photo from iPhone default camera in my App. It is taking long time to complete the process.

-(IBAction)takePhoto:(id)sender
{
    if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
    {
        imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        [self presentModalViewController:imgPicker animated:YES];
    }
}

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *pickedImage = [info objectForKey:UIImagePickerControllerOriginalImage];    
    [self dismissModalViewControllerAnimated:YES];

    NSData *imageData = UIImagePNGRepresentation(pickedImage);
    path = [SAVEDIMAGE_DIR stringByAppendingPathComponent:@"image.png"];
    [imageData writeToFile:path atomically:YES];
    [tableview reloadData];
}

Try these lines:

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;

imagePicker.delegate = self;

[self presentViewController:imagePicker animated:YES completion:nil];
