When pushing a page in the navigation， changing the state of interactivePopGestureRecognizer causes the page to freeze.
Just like this:
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
CGFloat red = (arc4random_uniform(256) / 255.0);
CGFloat green = (arc4random_uniform(256) / 255.0);
CGFloat blue = (arc4random_uniform(256) / 255.0);
CGFloat alpha = 1.0; //
self.view.backgroundColor = [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(0, 0, 100, 44);
btn.backgroundColor = [UIColor redColor];
btn.center = self.view.center;
[btn setTitle:@"push click" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
}
- (void)click:(id)sender {
[self.navigationController pushViewController:[ViewController new] animated:YES];
}
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
- (void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
}
@end

Activity
When my app is in the background, I create a Live Activity through a push notification with token get from pushToStartTokenUpdates, and this process works fine. However, without opening the app, how can I retrieve the new push token for this Live Activity again and use it for subsequent updates to the Live Activity content?
