1. UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)];   
2.     lpgr.minimumPressDuration = 1.0; //seconds  设置响应时间  
3.     lpgr.delegate = self;     
4.     [mTableView addGestureRecognizer:lpgr]; //启用长按事件  
5.     [lpgr release];  
6.   
7. -(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer  //长按响应函数  
8. {  
9. CGPoint p = [gestureRecognizer locationInView:mTableView ];  
10.   
11. //if(gestureRecognizer.state == UIGestureRecognizerStateBegan)  
12. //{  
13. //NSLog(@"UIGestureRecognizerStateBegan");  
14. //}  
15. //else if(gestureRecognizer.state == UIGestureRecognizerStateEnded)  
16. //{  
17. //NSLog(@"UIGestureRecognizerStateEnded");  
18. //}  
19. //else if(gestureRecognizer.state == UIGestureRecognizerStateChanged)  
20. //{  
21. //NSLog(@"UIGestureRecognizerStateChanged");  
22. //}  
23. //else if(gestureRecognizer.state == UIGestureRecognizerStateCancelled)  
24. //{  
25. //NSLog(@"UIGestureRecognizerStateCancelled");  
26. //}  
27. //else if(gestureRecognizer.state ==UIGestureRecognizerStateFailed )  
28. //{  
29. //NSLog(@"UIGestureRecognizerStateFailed");  
30. //}  
31.   
32.   
33. NSIndexPath *indexPath = [mTableview indexPathForRowAtPoint:p];//获取响应的长按的indexpath  
34. if (indexPath == nil)  
35. NSLog(@"long press on table view but not on a row");  
36. else  
37. NSLog(@"long press on table view at row %d", indexPath.row);  
38.   
39. } 

给UITableView 添加长按手势，识别长按哪一行。

长按手势类UILongPressGestureRecognizer， 属性minimumPressDuration表示最短长按的时间

添加手势代码：

UILongPressGestureRecognizer * longPressGr = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressToDo:)];   
     longPressGr.minimumPressDuration = 1.0;   
     [self.tableView addGestureRecognizer:longPressGr];   
    [longPressGr release];  

响应长按事件代码：

-(void)longPressToDo:(UILongPressGestureRecognizer *)gesture   
 {   
     if(gesture.state == UIGestureRecognizerStateBegan)   
     {   
         CGPoint point = [gesture locationInView:self.tableView];   
        NSIndexPath * indexPath = [self.tableView indexPathForRowAtPoint:point];   
         if(indexPath == nil) return ;   
        //add your code here   
    }   
 }
