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

bubuko.com,布布扣
_tableview.touchDelegate = self;

#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");

}
