iOS之侧滑返回无需第三方，只需在自己的BaseNavController添加大闲时多研究研究代码或者多多封装一些常

闲时多研究研究代码或者多多封装一些常用的类，对自己有利而无害，作为一个程序员，我觉得只要多看，多敲，多琢磨，慢慢滴你也就会成为大牛。

效果图

实现步骤：

1、viewDidLoad需要做的事情

self.delegate = self;

__weak typeof(self) weakSelf = self;

if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {

self.interactivePopGestureRecognizer.delegate = weakSelf;

}

2、实现UIGestureRecognizerDelegate代理中的方法

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

if (self.navigationController.viewControllers.count == 1) {

return NO;

}else{

return YES;

}

3、实现UINavigationControllerDelegate代理中的方法

1.实现didShowViewController方法

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{

if ([navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {

navigationController.interactivePopGestureRecognizer.enabled = YES;

}

//使navigationcontroller中第一个控制器不响应右滑pop手势

if (navigationController.viewControllers.count == 1) {

navigationController.interactivePopGestureRecognizer.enabled = NO;

navigationController.interactivePopGestureRecognizer.delegate = nil;

}

2.此方法中拦截所有push 进来的控制器

-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{

if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {

self.interactivePopGestureRecognizer.enabled = NO;

}

[super pushViewController:viewController animated:animated];

}
