SmartStickyPullToRefresh

Version License Platform

Smart, sticky pull to refresh control for any UIScrollView. Instead of relying on the header view of a table or collection view, SmartStickyPullToRefresh uses a custom banner view that drops down from a user-selected parentView after a parentScrollView surpasses stickyScrollViewActivationOffset (use stickyScrollViewPreActivationOffset for pre-activation instructions and stickyScrollViewDeactivationOffset to hide these instructions).

Usage

SmartStickyPullToRefresh *control = [[SmartStickyPullToRefresh alloc] init];

control.stickyParentView = self.navigationController.navigationBar; // attaches to bottom using same superview (animates INTO autolayout!)

control.stickyScrollView = self.tableView; // any UIScrollView with contentOffset for KVO -- use custom deactivate, preactivate, activate offsets

control.stickySmartDelegate = self; // a bunch of optional methods and required VALUE CHANGED

[control beginDetectingPullToRefresh]; // throw into viewWillAppear -- adds KVO as-needed to stickyScrollView to animate SmartStickyPullToRefresh (a UIView) beneath and anchored below stickyParentView

[control stopDetectingPullToRefresh]; // throw into viewWillDisappear -- removes KVO and any existing pull to refresh business

It is highly recommended to manually adjust the activation offsets, such as in the below snippet from Submarine:

refreshControl.stickyScrollViewDeactivationOffset = -CGRectGetMaxY(self.navigationController.navigationBar.frame) + (self.shyNavBarManager.extensionView ? -44.0 : 0);
refreshControl.stickyScrollViewPreActivationOffset = _smartPullToRefresh.stickyScrollViewDeactivationOffset - 50.0;
refreshControl.stickyScrollViewActivationOffset = _smartPullToRefresh.stickyScrollViewPreActivationOffset - 50.0;

To run the example project, clone the repo, and run pod install from the Example directory first.

Installation

SmartStickyPullToRefresh is available through CocoaPods. To install it, simply add the following line to your Podfile:
