h1. SVPullToRefresh
|
||||
|
||||
SVPullToRefresh allow you to easily add pull-to-refresh functionality to any UIScrollView subclass. Instead of depending on delegates and/or subclassing UIViewController, SVPullToRefresh extends UIScrollView with:
|
||||
|
||||
* a - (void)addPullToRefreshWithActionHandler:(void (^)(void))actionHandler method
|
||||
* a @pullToRefreshView@ property
|
||||
|
||||
h2. Installation
|
||||
|
||||
* Drag the @SVPullToRefresh/SVPullToRefresh@ folder into your project.
|
||||
* Add the *QuartzCore* framework to your project.
|
||||
* @#import "SVPullToRefresh.h"@
|
||||
|
||||
h2. Usage
|
||||
|
||||
(see sample Xcode project in @/Demo@)
|
||||
|
||||
Adding pull-to-refresh to a table view can be done with one single line of code:
|
||||
|
||||
<pre>
|
||||
[tableView addPullToRefreshWithActionHandler:^{
|
||||
// refresh data
|
||||
// call [tableView.pullToRefreshView stopAnimating] when done
|
||||
}];
|
||||
</pre>
|
||||
|
||||
h2. Customization
|
||||
|
||||
The SVPullToRefresh view can be customized with the following properties:
|
||||
|
||||
<pre>
|
||||
@property (nonatomic, strong) UIColor *arrowColor;
|
||||
@property (nonatomic, strong) UIColor *textColor;
|
||||
@property (nonatomic, readwrite) UIActivityIndicatorViewStyle activityIndicatorViewStyle;
|
||||
</pre>
|
||||
|
||||
h2. Under the hood
|
||||
|
||||
SVPullToRefresh extends UIScrollView by adding a new public method as well as a dynamic property (thanks @seb_morel!). It uses key-value observing to track the scrollView's contentOffset, which removes the need for the view to be linked to the UIScrollViewDelegate protocol.
|
||||
|
||||
