关于UIPageViewController去除边缘点击手势

 

如果page上方还有一层UI控件的话，不去除边缘点击手势会造成手势的冲突干扰。

首先我做的处理是设置pageView的手势代理

?

1 2 3 4 5 6 7 8 9 10 11 12 13

for (UIGestureRecognizer *gr in _pageViewController.gestureRecognizers) {            if ([gr isKindOfClass:[UIPanGestureRecognizer class]]) {                  gr.delegate = self;          } } -(BOOL) gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch    (UITouch *)touch {     if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {             return NO;          }     return YES;  }

 但是这样处理，会在第一页忘前翻页和在最后一页往后翻页出现crash，而且不清楚原因。

正确处理方法：

新建一个UIpageControlller的类别

?

1 2 3 4 5

#import <UIKit/UIKit.h>   @interface UIPageViewController (YCGestureTool)   @end

 

?

1 2 3 4 5 6 7 8 9 10

#import "UIPageViewController+YCGestureTool.h"   @implementation UIPageViewController (YCGestureTool)   -(BOOL) gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{     if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {         return NO;     }     return YES; }

 完美解决！
