I have applied gesture on whole view and I want to interact with table view within self.view.I have applied custom gesture.that is as follows:
#import "TouchEvent.h"
#import <UIKit/UIGestureRecognizerSubclass.h>
@implementation TouchEvent
@synthesize xInc=_inc;
@synthesize prev=_prev;
@synthesize diff=_diff;
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self setState:UIGestureRecognizerStateBegan];
}
-(void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
[self setState:UIGestureRecognizerStateCancelled];
}
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
// A tap can have slight movement, but we're not interested
// in a tap. We want more movement. So if a tap is detected
// fail the recognizer.
if ([self state] == UIGestureRecognizerStatePossible) {
[self setState:UIGestureRecognizerStateBegan];
} else {
[self setState:UIGestureRecognizerStateChanged];
}
UIView *view = [self view];
CGPoint touchpoint = [touch locationInView:view];
CGPoint prevPoint=[touch previousLocationInView:view];
if (prevPoint.x<touchpoint.x)
[self setDiff:(touchpoint.x-prevPoint.x)];
else
[self setDiff:(prevPoint.x-touchpoint.x)];
NSLog(@"difference is: %f",self.diff);
NSLog(@"x is: %f",touchpoint.x);
[self setXInc:touchpoint.x];
[self setPrev:prevPoint.x];
}
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
[self setState:UIGestureRecognizerStateEnded];
}
@end
and I m applying like this
- (void)viewDidLoad
{
NSArray *ary=[NSArray arrayWithObjects:@"Friends",@"Message",@"Chats",@"New Feeds",@"Photos",@"Notes", nil];
array=ary;
gestur=[[TouchEvent alloc] initWithTarget:self action:@selector(SLideTheView:)];
[self.view addGestureRecognizer:gestur];
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
-(void)moveIt:(CGFloat)x_pos
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[viewU setFrame:CGRectMake(x_pos, 0, 320, 460)];
[UIView commitAnimations];
}
-(void)SLideTheView:(TouchEvent*)gesture
{
CGPoint pt=[gesture locationInView:viewU];
if (pt.x>13&&pt.y>5&&pt.x<29&&pt.y<23)
{
[self slideView];
}
else
{
if (gesture.state==UIGestureRecognizerStateEnded)
{
if (viewU.frame.origin.x!=0) {
if (gesture.prev<gesture.xInc)
{
[self moveIt:270];
}
else
[self moveIt:0];
}
}
else
{
if (viewU.frame.origin.x!=0)
{
if (gesture.prev<gesture.xInc)
x=viewU.frame.origin.x+gesture.diff;
else
x=viewU.frame.origin.x-gesture.diff;
[viewU setFrame:CGRectMake(x, 0, 320, 460)];
}
}
}
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
label.text=[array objectAtIndex:[indexPath row]];
[self slideView];
}
the running image is as follows:

you can use requireGestureRecognizerToFail:
to able to recognize two or more gesture recognizers on same view see example code here
edit
so you can refer this one
the method to be referenced is - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
refer this question for more

//add gesture to mapview-for single touch
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(SLideTheView:)];
[self.view addGestureRecognizer:tap];
tap.numberOfTapsRequired = 1;
//add another gesture to terminate first one
UITapGestureRecognizer *secondGest= [[UITapGestureRecognizer alloc] init];
[tableview addGestureRecognizer:secondGest];
[tap requireGestureRecognizerToFail:secondGest];
[secondGest release];
[tap release];
