//導(dǎo)致側(cè)滑失效的設(shè)置
- navigationBarHidden
- navigationItem.hidesBackButton
- navigationItem.leftBarButtonItem/leftBarButtonItems

UINavigationController有一個(gè)交互手勢(shì)

@property(nullable, nonatomic, readonly) UIGestureRecognizer *interactivePopGestureRecognizer NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;

解決方法

@interface SecondViewController () <UIGestureRecognizerDelegate>
@property (nonatomic, strong) id<UIGestureRecognizerDelegate> originalDelegate;
@end

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    self.originalDelegate = self.navigationController.interactivePopGestureRecognizer.delegate;
    self.navigationController.interactivePopGestureRecognizer.delegate = self;
}

- (void)viewDidDisappear:(BOOL)animated {
    [super viewDidDisappear:animated];
    self.navigationController.interactivePopGestureRecognizer.delegate = self.originalDelegate;
    self.originalDelegate = nil;
}

修改側(cè)滑手勢(shì)的代理，注意在disappear的時(shí)候重置回去
