pod 'WZDraggableSwitchHeaderView', :git => 'https://github.com/wongzigii/WZDraggableSwitchHeaderView.git', :branch => 'master'#import "WZDraggableSwitchHeaderView.h"Create an instance of WZDraggableSwitchHeaderView:
self.headerView = [[WZDraggableSwitchHeaderView alloc] initWithDelegate:self
frame:CGRectMake(0,0,self.view.bounds.size.width,50)
normalStateHeight:20.0f
heightCanTriggerSwitch:70.0f];
[self.view addSubView:self.headerView]; Implement the delegate method that will be invoked:
#pragma mark - WZDraggableSwitchHeaderViewDelegate
- (void)WZDraggableSwitchHeaderViewDidTriggerDeepDragging;
{
[self.navigationController.view.layer addAnimation:[WZAnimatingTransition backwardTransition] forKey:@"transition"];
[self.navigationController popToRootViewControllerAnimated:NO];
}Hook on the UIScrollViewDelegate:
#pragma mark - UIScrollViewDelegate
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
[self.headerView WZDraggableSwitchHeaderViewDidScroll:scrollView];
}
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate
{
[self.headerView WZDraggableSwitchHeaderViewDidEndDragging:scrollView];
}Done!
