摘要：从iOS7开始,系统为UINavigationController提供了一个interactivePopGestureRecognizer用于右滑返回(pop),但是如果自定了当前视图控制器leftBarButtonItem,该手势就失效了。解决方法:自定义UINavigationController并实现其代理方法重新设置侧滑手势的代理。具体代码如下:classBaseNavigationController:UINavigationController,UINavigat
从iOS7开始,系统为UINavigationController提供了一个interactivePopGestureRecognizer用于右滑返回(pop),但是如果自定了当前视图控制器leftBarButtonItem,该手势就失效了。
解决方法:自定义UINavigationController并实现其代理方法重新设置侧滑手势的代理。
具体代码如下:
class BaseNavigationController: UINavigationController ,UINavigationControllerDelegate {
var popDelegate: UIGestureRecognizerDelegate?
override func viewDidLoad() {
super.viewDidLoad()
self.popDelegate = self.interactivePopGestureRecognizer?.delegate
self.delegate = self
}
// MARK: - UINavigationControllerDelegate方法
func navigationController(_ navigationController: UINavigationController, didShow viewController: UIViewController, animated: Bool) {
if viewController == self.viewControllers[0] {
self.interactivePopGestureRecognizer!.delegate = self.popDelegate
}
else {
self.interactivePopGestureRecognizer!.delegate = nil
}
}
