UIWebView倒是经常用，不过翻页功能没用过，因为还没写过电子书之类的应用，最近心血来潮写了个电子书的框架，这样就可以量产电子书应用了，哈哈。可是要实现翻页功能时发现UIwebView竟然接收不了touch事件，老郁闷了。网上有大牛的hack方法，不过审核貌似通不过。组后发现苹果官方给我们提供了专门的api，通过 UISwipeGestureRecognizer 来实现。
直接上代码吧：
- UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(previousPage)];
- swipeRight.direction=UISwipeGestureRecognizerDirectionRight;
- [webView addGestureRecognizer:swipeRight];
- [swipeRight release];
- UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(nextPage)];
- swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;
- [webView addGestureRecognizer:swipeLeft];
- [swipeLeft release];
一看代码应该就明白了。苹果官方给我们的手势有4个，分别对应上下左右：
- typedef enum {
- UISwipeGestureRecognizerDirectionRight = 1 << 0,
- UISwipeGestureRecognizerDirectionLeft = 1 << 1,
- UISwipeGestureRecognizerDirectionUp = 1 << 2,
- UISwipeGestureRecognizerDirectionDown = 1 << 3
- } UISwipeGestureReco
