一个大的猫窝,voidcat

- (void)viewWillDisappear:(BOOL)animated {

    [super viewWillDisappear:YES];

    self.navigationController.interactivePopGestureRecognizer.enabled = YES;

}

- (void)viewDidAppear:(BOOL)animated {

    [super viewDidAppear:YES];

    self.navigationController.interactivePopGestureRecognizer.enabled = NO;

}

需要在viewWillDisappear 添加 self.navigationController.interactivePopGestureRecognizer.enabled = YES;

否则可能会造成页面卡死情况。
