iOS侧滑卡住问题

1.在你的UINavigationController里面
.m

import "CBNavigationController.h"

@implementation CBNavigationController

• (void)viewDidLoad
  {
  __weak CBNavigationController *weakSelf = self;

  if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)])
  {
  self.interactivePopGestureRecognizer.delegate = weakSelf;

    self.delegate = weakSelf;
  

  }
  }

// Hijack the push method to disable the gesture

• (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
  {
  if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]&&animated==YES){
  // 防止在push下一个界面动画过程中，用户左侧手势返回，手势冲突造成的crash，先将侧滑关闭
  self.interactivePopGestureRecognizer.enabled = NO;
  }

  [super pushViewController:viewController animated:animated];
  }

• (NSArray *)popToRootViewControllerAnimated:(BOOL)animated
  {
  if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]&&animated==YES){
  self.interactivePopGestureRecognizer.enabled = NO;
  }

  return [super popToRootViewControllerAnimated:animated];
  }

• (NSArray *)popToViewController:(UIViewController *)viewController animated:(BOOL)animated
  {

  if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]){
  self.interactivePopGestureRecognizer.enabled = NO;
  }

  return [super popToViewController:viewController animated:animated];
  }

pragma mark UINavigationControllerDelegate

• (void)navigationController:(UINavigationController *)navigationController

   didShowViewController:(UIViewController *)viewController
  
                animated:(BOOL)animate
  

{

// Enable the gesture again once the new controller is shown
if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]){
    // 页面加载完成后，将侧滑手势打开
    self.interactivePopGestureRecognizer.enabled = YES;
    if (self.viewControllers.count < 2 || self.visibleViewController == [self.viewControllers objectAtIndex:0]) {
        self.interactivePopGestureRecognizer.enabled = NO;
    }

}

}

-(BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
NSLog(@"123");

if (gestureRecognizer==self.interactivePopGestureRecognizer) {
    
    if (self.viewControllers.count < 2 || self.visibleViewController == [self.viewControllers objectAtIndex:0]) {
        return NO;
    }
}
return YES;

}
