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
@protocol TouchTableViewDelegate
@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{
IBOutlet UISegmentedControl *_sigTime;
IBOutlet TouchTableView *_tableview;
}
@end
_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");
}
