You will using UISwipeGestureRecognizer Object to detect the Touch and direction of Swipe In

UIView or anywhere in iphone sdk.

 UISwipeGestureRecognizer *rightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightSwipeHandle:)];
rightRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
[rightRecognizer setNumberOfTouchesRequired:1];

//add the your gestureRecognizer , where to detect the touch..
[view1 addGestureRecognizer:rightRecognizer];
[rightRecognizer release];

UISwipeGestureRecognizer *leftRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwipeHandle:)];
leftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
[leftRecognizer setNumberOfTouchesRequired:1];

[view1 addGestureRecognizer:leftRecognizer];
[leftRecognizer release];

 - (void)rightSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer
 {
     NSLog(@"rightSwipeHandle");
 }

 - (void)leftSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer 
 {
NSLog(@"leftSwipeHandle");
 }

I think this the Better solution for your problem
