//添加我想在行动didrangebeacons开启后打开子视图。但是当它去那里时屏幕上没有任何视图。只是这个错误消息

以前的问题相同，但对我的问题没有帮助。我没有任何故事板或xib文件，只是清晰的编程。

BeaconViewController：UINavigationController上的0x155eb5b0：0x1559bfe0，其视图不在窗口层次结构中！

AppDelegate.m：

- (void) viewDidAppear {

}

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

DebugLog(@"");

NSLog(@"good1");


//and then access the variable by appDelegate.variable
// Оповещение о том, что надо включить Bluetooth, через минут, через 10 минут, через 8 часов, через неделю

[self loadNotificationRegions];

// Google Analytics
// Optional: automatically send uncaught exceptions to Google Analytics.
[GAI sharedInstance].trackUncaughtExceptions = YES;
// Optional: set Google Analytics dispatch interval to e.g. 20 seconds.
[GAI sharedInstance].dispatchInterval = 20;
// Optional: set debug to YES for extra debugging information.
[GAI sharedInstance].debug = YES;
// Create tracker instance.
id <GAITracker> tracker = [[GAI sharedInstance] trackerWithTrackingId:@"UA-42731391-1"];

// Check if the app needs to read the settings from file
NSString *transition = [[NSUserDefaults standardUserDefaults] stringForKey:@"transitionStyle"];

// Note: this will not work for boolean values as noted by bpapa below.
// If you use booleans, you should use objectForKey above and check for null
if (!transition) {
    [self readFromSettingsFile];

替换

UINavigationController *navController = [[UINavigationController alloc] init];

与

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController...

可能会解决问题

在一个不相关的笔记上杀死菊花链就像这样 - （void）vidDidAppear {
