侧滑手势

//创建侧滑手势并绑定方法

//指定在哪个边缘侧滑UIRectEdgeNone UIRectEdgeTop UIRectEdgeLeft UIRectEdgeBottom UIRectEdgeRight UIRectEdgeAll

SEPGesture.edges=UIRectEdgeLeft;

//设置代理导人UIGestureRecognizerDelegate可实现下面两个BOOL的方法

SEPGesture.delegate=self;

//添加

[self.viewaddGestureRecognizer:SEPGesture];

}

//返回手势是否执行

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {

//由于这个类是要ios7以上的版本才可使用进行判断可避免运行崩溃

}

}

}

//失败时返回，other是否有效，如果gestureRecognizer失效时，就使用otherGestureRecognizer
