• 目前有三种方案:

  1.

  UIScrollView + UITableView。

  实现方法,在UIScrollView中,加入UITableView即可

  设置UIScrollView的代理和方法

  - (void)scrollViewDidScroll:(UIScrollView *)scrollView{ int currentPostion = scrollView.contentOffset.x; if (currentPostion - 0 > 50) { NSLog(@"Scroll right now "); } else if (0 - currentPostion > 50) { NSLog(@"Scroll left now"); }}

  2.利用UISwipeGestureRecognizer

  -(void)viewDidLoad{UISwipeGestureRecognizer *recognizer;recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];[recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];[[self view] addGestureRecognizer:recognizer];recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];[recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];[[self view] addGestureRecognizer:recognizer];recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];[recognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];[[self view] addGestureRecognizer:recognizer];recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];[recognizer setDirection:(UISwipeGestureRecognizerDirectionDown)];[[self view] addGestureRecognizer:recognizer];}-(void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer{if(recognizer.direction==UISwipeGestureRecognizerDirectionDown) {NSLog(@"swipe down");//执行程序}if(recognizer.direction==UISwipeGestureRecognizerDirectionUp) {NSLog(@"swipe up");//执行程序}if(recognizer.direction==UISwipeGestureRecognizerDirectionLeft) {NSLog(@"swipe left");//执行程序}if(recognizer.direction==UISwipeGestureRecognizerDirectionRight) {NSLog(@"swipe right");//执行程序}}

  UITableView 屏蔽了左右滑动事件.  通过重载的方式可以注入事件touch事件, 供开发者使用..

  #import <UIKit/UIKit.h> @protocol TouchTableViewDelegate <NSObject> @optional - (void)tableView:(UITableView *)tableView touchesBegin:(NSSet *)touches withEvent:(UIEvent *)event; - (void)tableView:(UITableView *)tableView touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event; - (void)tableView:(UITableView *)tableView touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event; - (void)tableView:(UITableView *)tableView touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event; @end 
  #import "TouchTableView.h" @implementation TouchTableView @synthesize touchDelegate = _touchDelegate; - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesBegan:touches withEvent:event]; if ([_touchDelegate conformsToProtocol:@protocol(TouchTableViewDelegate)] &;&; [_touchDelegate respondsToSelector:@selector(tableView:touchesBegin:withEvent:)]) { [_touchDelegate tableView:self touchesBegin:touches withEvent:event]; } } - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesCancelled:touches withEvent:event]; if ([_touchDelegate conformsToProtocol:@protocol(TouchTableViewDelegate)] &;&; [_touchDelegate respondsToSelector:@selector(tableView:touchesCancelled:withEvent:)]) { [_touchDelegate tableView:self touchesCancelled:touches withEvent:event]; } } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesEnded:touches withEvent:event]; if ([_touchDelegate conformsToProtocol:@protocol(TouchTableViewDelegate)] &;&; [_touchDelegate respondsToSelector:@selector(tableView:touchesEnded:withEvent:)]) { [_touchDelegate tableView:self touchesEnded:touches withEvent:event]; } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesMoved:touches withEvent:event]; if ([_touchDelegate conformsToProtocol:@protocol(TouchTableViewDelegate)] &;&; [_touchDelegate respondsToSelector:@selector(tableView:touchesMoved:withEvent:)]) { [_touchDelegate tableView:self touchesMoved:touches withEvent:event]; } } @end 调用方法 :1. 头文件中加入delegate @interface MoneyViewCtl : UIViewController<UITableViewDataSource, UITableViewDelegate, SDWebDataDownloaderDelegate, EGORefreshTableHeaderDelegate, TouchTableViewDelegate>{ IBOutlet UISegmentedControl *_sigTime; IBOutlet TouchTableView *_tableview; }@end

   2. .m文件中设置好delegate

  _tableview.touchDelegate = self;

   3. .m文件中实现如下事件 

  #pragma mark - TouchTableViewDelegate lifecycle- (void)tableView:(UITableView *)tableView touchesBegin:(NSSet *)touches withEvent:(UIEvent *)event{ NSLog(@"touchesBegin");}- (void)tableView:(UITableView *)tableView touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event{ NSLog(@"touchesCancelled");} - (void)tableView:(UITableView *)tableView touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ NSLog(@"touchesEnded");}- (void)tableView:(UITableView *)tableView touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ NSLog(@"touchesMoved");}
