首先，用到一个开源框架，可以去https://github.com/enormego/EGOTableViewPullRefresh下载。
然后，将里面的EGORefreshTableHeaderView.h和EGORefreshTableHeaderView.m拷到相应的项目里，在需要下拉刷新的页面对应的视图控制器中添加以下代码。
头文件：
#import "EGORefreshTableHeaderView.h"
@interface RootViewController : UITableViewController <EGORefreshTableHeaderDelegate, UITableViewDelegate, UITableViewDataSource>{
EGORefreshTableHeaderView *_refreshHeaderView;
BOOL _reloading;
}
- (void)reloadTableViewDataSource;
- (void)doneLoadingTableViewData;
@end
实现文件：
#import "RootViewController.h"
@implementation RootViewController
- (void)viewDidLoad {
[super viewDidLoad];
if (_refreshHeaderView == nil) {
EGORefreshTableHeaderView *view = [[EGORefreshTableHeaderView alloc] initWithFrame:CGRectMake(0.0f, 0.0f - self.tableView.bounds.size.height, self.view.frame.size.width, self.tableView.bounds.size.height)];
view.delegate = self;
[self.tableView addSubview:view];
_refreshHeaderView = view;
[view release];
}
[_refreshHeaderView refreshLastUpdatedDate];
}
#pragma mark -
#pragma mark UITableViewDataSource
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 10;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 4;
}

static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
return cell;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
return [NSString stringWithFormat:@"Section %i", section];
}

最后，一个很重要的步骤，别忘了加入QuartzCore.framework框架。
public boolean onTouchEvent(MotionEvent event) {
if(mAction == TOUCH_ACTION_MOVE){
return false;
}
boolean consumed = mGestureDetector.onTouchEvent(event);
// if (event.getAction() == MotionEvent.ACTION_UP) {
// if (mIsTouched || mIsDragging) {
// processScrollSnap();
// processGesture();
// }
// }
// return super.onTouchEvent(event);
return consumed;
}
public boolean dispatchTouchEvent(MotionEvent event) {
boolean consumed = mGestureDetector.onTouchEvent(event);
final int action = event.getAction();
Log.d("eeeee", "dispatchTouchEvent action="/blog_article/action/index.html", mAction="+mAction);
final float x = event.getX();
final float y = event.getY();
switch(action){
case MotionEvent.ACTION_DOWN:
mAction = TOUCH_ACTION_NONE;
mLastMotionX = x;
mLastMotionY = y;
break;
case MotionEvent.ACTION_MOVE:
int deltaX = (int) (mLastMotionX - x);
int deltaY = (int) (mLastMotionY - y);
if (mAction == TOUCH_ACTION_NONE) {
if (Math.abs(deltaX) < 10 && Math.abs(deltaY) > 10) {
mAction = TOUCH_ACTION_MOVE;
} else if (Math.abs(deltaX) > 10 && Math.abs(deltaY) < 10) {
mAction = TOUCH_ACTION_SNAP;
}
break;
}
if(mAction == TOUCH_ACTION_SNAP){
return true;
}else if(mAction == TOUCH_ACTION_MOVE){
return super.dispatchTouchEvent(event);
}
break;
case MotionEvent.ACTION_UP:
if (mIsTouched || mIsDragging) {
processScrollSnap();
processGesture();
return consumed;
}
mAction = TOUCH_ACTION_NONE;
default:
mAction = TOUCH_ACTION_NONE;
break;
}
// return consumed;
return super.dispatchTouchEvent(event);
}
