CustomPullToRefreshControl

Based off Fabio Ritrovato's ODRefreshControl.

Properties:

@property (nonatomic, assign) UIActivityIndicatorViewStyle activityIndicatorViewStyle;
@property (nonatomic, strong) UIColor *activityIndicatorViewColor; // iOS5 or more
@property (nonatomic, strong) UIColor *tintColor;
@property (nonatomic, strong) UIColor *strokeColor
@property (nonatomic, strong) UIColor *shadowColor

@property (nonatomic, assign) BOOL drawDiskWhenPulling
@property (nonatomic, assign) BOOL enableDiskDripEffect
@property (nonatomic, assign) BOOL stickToTopWhenRefreshing
@property (nonatomic, assign) BOOL scrollUpToCancel

/** Refresh animation on custom pullView */
@property (nonatomic, assign) CustomPullToRefreshStyle refreshStyle;
@property (nonatomic, assign) CustomPullToRefreshEasing refreshEasing;

Enums

// Enum for refresh style animation on pullView
typedef enum {
	CustomPullToRefreshNone,
	CustomPullToRefreshSpin,
	CustomPullToRefreshRotate,
} CustomPullToRefreshStyle;

// Enum for animation easing on pullView
typedef enum {
	CustomPullToRefreshLinear,
	CustomPullToRefreshMomentum,
	CustomPullToRefreshContinuous
} CustomPullToRefreshEasing;

Added features:

• Custom stroke & shadow colors.
• Can turn on or off the drippy-slimey effect.
• Can cancel refresh by scrolling back to rest position for user-defined time, and will emit a UIControlEventTouchCancel action for targets to listen to.
• Can position the refreshing activity indicator / custom view to top of screen or top of scrollView.
• Custom ImageView in place of arrow, which you can animate using custom styles.
• Custom animation styles using linear and momentum "easing", and spin or rotate transforms.
• Added functionality to reposition if scrollview gets scrolled horizontally.

Known Issues:

• You can't use the Rotate style animation with the drippy-slimey effect on.
• You can only use the custom animation styles on a custom imageview.
• It looks like if you set this on a regular UIScrollView and enable paging, the activity indicator doesn't stay at the top. Working on this.

Original ODRefreshControl Readme (modified for this library)

Important note if your project doesn't use ARC: you must add the "-fobjc-arc" compiler flag to "CustomPullToRefresh.m" in Target Settings > Build Phases > Compile Sources.

If you are using CustomPullToRefresh in your app, drop me a line so I can add your app here!

CustomPullToRefresh

CustomPullToRefresh is a "pull down to refresh" control for UIScrollView, like the one Apple introduced in iOS6, but available to anyone from iOS4 and up.

Installation

• Drag the CustomPullToRefresh folder into your project.
• Add the QuartzCore framework to your project.
• #import "CustomPullToRefresh.h"

Adding a refresh control to your table view

CustomPullToRefresh *refreshControl = [[CustomPullToRefresh alloc] initInScrollView:self.scrollView];

To know when the refresh operation has started, add an action method to the UIControlEventValueChanged event of the control

[refreshControl addTarget:self action:@selector(dropViewDidBeginRefreshing:) forControlEvents:UIControlEventValueChanged];

If you’d like to programmatically start the refresh operation, use

[refreshControl beginRefreshing];

Remember to tell the control when the refresh operation has ended

[refreshControl endRefreshing];

Customization

The CustomPullToRefresh can be customized using the following properties:

@property (nonatomic, strong) UIColor *tintColor;
@property (nonatomic, assign) UIActivityIndicatorViewStyle activityIndicatorViewStyle;
@property (nonatomic, strong) UIColor *activityIndicatorViewColor; // iOS5 or more
