如何禁用UINavigation Controller的滑动手势

Question

在App代表中：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];


    WalkThrough  *viewControllers=[[WalkThrough alloc]init];
    self.navigationController = [[UINavigationController alloc] initWithRootViewController:viewControllers];



[self.window setRootViewController:self.navigationController];
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
navigationController.navigationBar.hidden = YES;
self.window.backgroundColor = [UIColor clearColor];
[self.window makeKeyAndVisible];

return YES;
}

Answer 1

尝试在 [window makeKeyAndVisible]之后停用interactivePopGestureRecognizer 。

问题的关键是interactivePopGestureRecognizer属性为nil，直到 两者 满足两个条件：

1. navigationController与窗口

相关联

2. 窗口变为关键且可见
