一、首先创建BaseController，在viewDidLoad里：
id target = self.navigationController.interactivePopGestureRecognizer.delegate;
// handleNavigationTransition:为系统私有API,即系统自带侧滑手势的回调方法，我们在自己的手势上直接用它的回调方法
UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:target action:@selector(handleNavigationTransition:)];
panGesture.delegate = self; // 设置手势代理，拦截手势触发
[self.view addGestureRecognizer:panGesture];
// 一定要禁止系统自带的滑动手势
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
// 什么时候调用，每次触发手势之前都会询问下代理方法，是否触发
// 作用：拦截手势触发
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
// 当当前控制器是根控制器时，不可以侧滑返回，所以不能使其触发手势
if(self.navigationController.childViewControllers.count == 1)
{
return NO;
}
return YES;
}
二、UIScrollView左右滑动手势与返回手势冲突的解决办法
解决办法是自定义ScrollView，重写- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event方法，代码如下：
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
UIView *hitView = [super hitTest:point withEvent:event];
if (point.x <= 10) { //这个值是调整返回手势里屏幕的距离
hitView = nil;
} else {
hitView = [super hitTest:point withEvent:event];
}
return hitView;
}
