VGParallaxHeader可以實現多種不同表頭效果。包括拉長、放大圖片、變換顏色等。

Import UIScrollView+VGParallaxHeader.h, and use as follows:

- (void)viewDidLoad {
    [super viewDidLoad];

    HeaderView *headerView = [HeaderView alloc] init];

    // or self.tableView
    [self.scrollView setParallaxHeaderView:headerView
                                      mode:VGParallaxHeaderModeFill // For more modes have a look in UIScrollView+VGParallaxHeader.h 
                                    height:200
                           shadowBehaviour:VGParallaxHeaderShadowBehaviourDisappearing]; // For more behaviours have a look in UIScrollView+VGParallaxHeader.h 
}

#pragma mark - UIScrollView Delegate
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    // This must be called in order to work
    [self.scrollView shouldPositionParallaxHeader];

    // scrollView.parallaxHeader.progress - is progress of current scroll
    NSLog(@"Progress: %f", scrollView.parallaxHeader.progress);
}
