PullToRefresh

A twitter-style pull-to-refresh NSScrollView with the added functionality of delegate protocols.

A slightly modified version of: Leah Culver's PullToRefresh and Alex Zielenski's ScrollToRefresh

Key Features

• Elastic Scroll
• Added optional delegate protocol method: ptrScrollViewDidTriggerRefresh:(id)sender
  • This method gets called when the user scrolls beyond the set bounds.

Directions

1. Link against the QuartzCore framework (under Targets > Build Phases > Link Binarry With Libraries).
2. Copy the following files to your project:

• PullToRefreshClipView.h/PullToRefreshClipView.m;
• PullToRefreshScrollView.h/PullToRefreshScrollView.m;
• PullToRefreshDelegate.h;
• pull-to-refresh-arrow.png and;
• release-to-refresh.png.

3. Add a TableView or OutlineView from the Object Library to your nib file and subclass the ScrollView as a PullToRefreshScrollView.
4. Create an outlet in your controller:

@property (weak) IBOutlet PullToRefreshScrollView *ptrScrollView;
  

5. Set the delegate:

- (void)awakeFromNib {
    NSLog(@"awake from nib");
    [_ptrScrollView setDelegate:self];
  }
  

6. Add the delegate method:

- (void)ptrScrollViewDidTriggerRefresh:(id)sender {
    NSLog(@"This is called by the PullToRefresh delegate protocol");
  }
  

7. Customize the delegate method as needed.
