  To avoid developers manually adjust contentInset refresh the appearance of the control after the impact of the visual experience;
  the most common situation, the absence of data, the bottom of the refresh control is not hidden, the use of KafkaRefresh to avoid the problem.

• Anti-dithering at the end of the refresh

  When the refresh control finishes refreshing, if UIScrollView is in a scrolling state, KafkaRefresh will adjust the contntOffset that controls the UIScrollView at this time according to the refresh control.

• Support setting the offset threshold to trigger refresh

  Setting the value of stretchOffsetYAxisThreshold can control the refresh pull distance.This property is a ratio relative to the height of the control and must be set greater than 1.0.

• Support global setting

  KafkaRefreshDefaults is a singleton for global settings

• Support progress callback

  Real-time callback Drag the offset ratio, for the expansion of the interface, according to the progress of adjustment animation.

• Adaptive contentInset system adjustment and manual adjustment

  Adaptive UINavigationController for UIScrollView's contentInset property adjustment, even if the contentInset automatically set value, then KafkaRefresh can still adapt this adjustment.

Installation

• CocoaPods

• Carthage

If anyone wants to install by carthage , please supply a pull request. I'm not using this package manager myself.

Usage

 #import "KafkaRefresh.h" 

Initialization

• The first way

[self.tableView bindRefreshStyle:KafkaRefreshStyleAnimatableArrow fillColor:MainColor animatedBackgroundColor:[UIColor redColor] atPosition:KafkaRefreshPositionHeader refreshHanler:^{
		 //to do something... 
	}];	

• The second way

 KafkaArrowHeader * arrow = [[KafkaArrowHeader alloc] init];
 arrow.refreshHandler = ^{
	 //to do something... 
 };
 self.tableView.headRefreshControl = arrow;

• The third way(global configuration)

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
	[[KafkaRefreshDefaults standardRefreshDefaults] setHeaderDefaultStyle:KafkaRefreshStyleAnimatableRing];
	return YES;
}

[self.tableView bindDefaultRefreshStyleAtPosition:KafkaRefreshPositionHeader refreshHanler:^{
		//to do something... 
}];

Trigger Refresh Manually

 [self.tableView.headRefreshControl beginRefreshing];
 [self.tableView.footRefreshControl beginRefreshing];

End Refresh

When you finish refreshing and don't need to show any hints, or any animation, call the following method.

- (void)endRefreshing; 

When you finish the refresh and need to display the prompt message, call the following method.

- (void)endRefreshingWithAlertText:(NSString *)text completion:(dispatch_block_t)completion; 

When you end the refresh and no longer need to refresh, call the following method.

- (void)endRefreshingAndNoLongerRefreshingWithAlertText:(NSString *)text;

Resume Refresh Available

/**
 After you call ‘endRefreshingAndNoLongerRefreshingWithAlertText’,
 you need to resume refresh available
 */
- (void)resumeRefreshAvailable;

Customize

Take KafkaheadRefreshControl as an example

 #import "KafkaheadRefreshControl.h"
 @interface CustomHeader : KafkafootRefreshControl
 @end

@implementation CustomHeader 

- (void)kafkaDidScrollWithProgress:(CGFloat)progress max:(const CGFloat)max{
   //progress callback
}

- (void)kafkaRefreshStateDidChange:(KafkaRefreshState)state{
   [super kafkaRefreshStateDidChange:state];
}
@end

Precautions

Please update the latest version； After iOS 11, if you use estimatedRowHeight and the estimatedRowHeight height is too far from the true height, UITableView repeated refreshes may occur before version 0.8.3, which has been resolved since version 0.8.3 (iOS bug)
