iOS5新增加的功能
UIPageViewController
非 常好用，封装了翻页功能操作，只需要给相应对象传入source就可以达到翻页的效果，但是有个问题值得注意，如果你需要在UIPageView添加控 件，默认情况下UIPageViewController是不会处理此控件事件的，解决办法是重写手势处理方法，当用户点击屏幕时，可根据程序里设计的位 置来决定是否需要进行翻页操作。下面的代码是在UIPageViewControllerDelegate实现类下重写 gestureRecognizer方法。
//Insert the following codes into method viewDidLoad of the implement of UIPageViewControllerDelegate
for
(UIGestureRecognizer
*gR
in self.view.gestureRecognizers
)
{
for
(UIGestureRecognizer
*gR
in self.view.gestureRecognizers
)
{
gR.delegate
= self;
}
//Override method gestureRecognizer, return false is disabled events.
–
(
BOOL
)gestureRecognizer
:
(UIGestureRecognizer
*
)gestureRecognizer shouldReceiveTouch
:
(UITouch
*
)touch
{
//Touch gestures below top bar should not make the page turn.
//EDITED Check for only Tap here instead.
if
(
[gestureRecognizer isKindOfClass
:
[UITapGestureRecognizer class
]
]
)
{
CGPoint touchPoint
=
[touch locationInView
:self.view
];
if
(touchPoint.y >
40
)
{
//Which position you want disable the gesture events.
return
NO;
}
}
return
YES;
}
