IOS 隐藏导航栏之后 左边框 右划返回

思路: 新建一个BaseVC, BaseVC里实现右划事件的代理, 所有的VC都继承于这个BaseVC.

.h

#import 
 
NS_ASSUME_NONNULL_BEGIN
 
@interface BaseViewController : UIViewController
 
@end
 
NS_ASSUME_NONNULL_END

.m

#import "BaseViewController.h"
 
@interface BaseViewController ()<UIGestureRecognizerDelegate>
 
@end
 
@implementation BaseViewController
 
- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.navigationController.interactivePopGestureRecognizer.delegate = self;
}
 
@end

self.navigationController.interactivePopGestureRecognizer.delegate = self;

也可以写成

self.navigationController.interactivePopGestureRecognizer.delegate = nil; 

上面的UIGestureRecognizerDelegate就可以不引入了.
