SPPullView is a simple pull to refresh implementation using a UIScrollView. Similar to refresh views used by the New York Times, Facebook, and Sparrow. Updated for ARC support and based off of Pull To Refresh View. See example image from New York Times app below.

• Download SPPullView and add SPPullView.h and SPPullView.m to your project
• Import SPPullView.h to your class
• Create an instance variable for SPPullView in your classes .h like this and synthesize it in your .m
• In your viewDidLoad (or wherever you'd like) create the PullView and pass in the UIScrollView you are using

SPPullView now has a style property (PullViewStyleDefault and PullViewStyleSimple) that can be passed in init to change the style of the PullView. If you don't pass in a property it will just load the default Style. However the new styles can be accessed as such:

self.pullView = [SPPullView pullViewWithScrollView:self.scrollView andStyle:PullViewStyleSimple];

PullViewStyleSimple is simply cosmetic changes, such as the removal of the last updated method. Also it replaces the loading text with the Activity View.

self.pullView = [SPPullView pullViewWithScrollView:self.scrollView];

• You'll need to add yourself as a delegate of SPPullView so that you can be notified when you should refresh your data. The only method is

- (void) pullViewShouldRefresh:(SPPullView *) view;

This is called when the user has dragged the pull view to the refresh point and released.

• Then just add the pullView to your UIScrollView

[self.scrollView addSubview:self.pullView];

• The only thing you need to worry about is letting the PullView know when your data is done loading, just as simple as calling

[self.pullView finishedLoading];

//Called when the user pulls to refresh (this is when you should update your data)
- (void) pullViewShouldRefresh: (SPPullView *) view;
