侧滑返回功能失效解决

自定义一个UINavigationController，实现几个代理方法

@interface CustomNavigationController : UINavigationController

@end

#import "CustomNavigationController.h"

@interface CustomNavigationController ()<UINavigationControllerDelegate, UIGestureRecognizerDelegate>
@property(nonatomic, weak) UIViewController *currentShowVC;
@end

@implementation CustomNavigationController

- (instancetype)initWithRootViewController:(UIViewController *)rootViewController {
CustomNavigationController *nav = [super initWithRootViewController:rootViewController];
nav.interactivePopGestureRecognizer.delegate = self;
nav.delegate = self;
return nav;
}

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
if (1 == navigationController.viewControllers.count) {
self.currentShowVC = nil;
} else {
self.currentShowVC = viewController;
}
}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
if (gestureRecognizer == self.interactivePopGestureRecognizer) {
return (self.currentShowVC == self.topViewController);
}
return YES;
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]] &&
[otherGestureRecognizer isKindOfClass:[UIScreenEdgePanGestureRecognizer class]]) {
return YES;
} else {
return NO;
}
}
@end

然后，将你的UINavigationController都替换成该自定的NavigationController就OK了
