有没有简单的方法来检测 iPhone 的此类手势？
我可以使用touchesBegan、touchesMoved、touchesEnded。但我该如何实现这些手势呢？ thz u。
您将使用 UISwipeGestureRecognizer 对象来检测轻扫的触摸和方向
UIView 或 iphone sdk 中的任何位置。
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");
}
我认为这是解决您问题的更好方法
