ios 关于页面侧滑和tableview 删除问题

作者: 师景福 | 来源:发表于2019-06-24 09:58 被阅读0次

    页面侧滑和tableview的冲突时,我的解决方案

    ViewDidload中添加以下代码:

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

     self.navigationController.interactivePopGestureRecognizer.delegate = self;

     self.navigationController.interactivePopGestureRecognizer.enabled = YES;

        }

    我是继承UINavigationController不需要进行优化操作体验有需要的可以添加下面的方法;

    但是回到navigationController的最顶层的Controller的时候再次侧滑之后,点击某个要push页面的地方,就会造成软件假死,怎么划都没用。

       解决办法:

    回到navigationController最上层页面的时候实现以下方法:

    - (void)viewDidAppear:(BOOL)animated{

    [super viewDidAppear:animated];

     self.navigationController.interactivePopGestureRecognizer.enabled = NO;

      }

      即在最上层页面不侧滑返回的时候把的话返回手势关闭掉即可解决这个假死问题,

    #import "SJFBaseNavViewController.h"

    @interface SJFBaseNavViewController ()<UINavigationControllerDelegate,UIGestureRecognizerDelegate>

    @end

    @implementationSJFBaseNavViewController

    - (void)viewDidLoad {

        [super viewDidLoad];

        // Do any additional setup after loading the view.

        __weak SJFBaseNavViewController *weakSelf = self;

        if([selfrespondsToSelector:@selector(interactivePopGestureRecognizer)]) {

            self.interactivePopGestureRecognizer.delegate = weakSelf;

            self.delegate= weakSelf;

        }

    }

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

        // 让系统的侧滑返回生效

        self.interactivePopGestureRecognizer.enabled = YES;

        if(viewController ==self.viewControllers[0]) {

            self.interactivePopGestureRecognizer.delegate = self; // 不支持侧滑

        }else{

            self.interactivePopGestureRecognizer.delegate = nil; // 支持侧滑

        }

    }

    #pragma mark - UIGestureRecognizerDelegate

    //这个方法是在手势将要激活前调用:返回YES允许右滑手势的激活,返回NO不允许右滑手势的激活

    - (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer*)gestureRecognizer

    {

        if(gestureRecognizer ==self.interactivePopGestureRecognizer) {

            //屏蔽调用rootViewController的滑动返回手势,避免右滑返回手势引起死机问题

            if (self.viewControllers.count < 2 ||

                self.visibleViewController == [self.viewControllers objectAtIndex:0]) {

                returnNO;

            }

        }

        //这里就是非右滑手势调用的方法啦,统一允许激活

        return YES;

    }

    @end
