升级了最新的XCode以后App运行异常了

苍狼传说

因为测试的iPhoneX手机系统升级了,连带的XCode也一起升了级，原来好好的程序现在打开白屏了，请教一下是为啥呢？

代码在下面:

AppDelegate.m中的代码

1. #import "AppDelegate.h"
   
2. #import "APIManager.h"
   
3. #import "APIWindowContainer.h"
   
4. #import "APIEvent.h"
   
5. #import "APIWebView.h"
   
6. #import "APIScriptMessage.h"
   
7. #import "APIModuleMethod.h"
   
8. #import "UZAppUtils.h"
   
9. #import "WebView.h"
   
10. 
    
11. @interface AppDelegate ()
    
12. 
    
13. @end
    
14. 
    
15. @implementation AppDelegate
    
16. 
    
17. APIWindowContainer *windowContainer=nil;
    
18. MyWebView *webview=nil;
    
19. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
20.     APIConfiguration *configuration = [[APIConfiguration alloc] init];
    
21.     // 调试时可以开启WiFi代码同步功能
    
22.     configuration.enableWifiSync = NO;
    
23.     [[APIManager sharedManager] initSDKWithLaunchOptions:launchOptions configuration:configuration];
    
24. 
    
25.     self.window=[[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    
26. 
    
27.     NSString *url = @"widget://index.html";
    
28.     NSString *name = @"index";
    
29. 
    
30.     webview=[MyWebView new];
    
31.     UINavigationController *nav=[webview loadURL:url winName:name];
    
32.     self.window.rootViewController=nav;
    
33.     //[nav setNavigationBarHidden:NO];
    
34.     return YES;
    
35.    
    
36. 
    
37. }
    
38. 
    
39. 
    
40. - (void)applicationWillResignActive:(UIApplication *)application {
    
41.     // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    
42.     // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
    
43. }
    
44. 
    
45. 
    
46. - (void)applicationDidEnterBackground:(UIApplication *)application {
    
47.     // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    
48.     // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    
49. }
    
50. 
    
51. 
    
52. - (void)applicationWillEnterForeground:(UIApplication *)application {
    
53.     // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
    
54. }
    
55. 
    
56. 
    
57. - (void)applicationDidBecomeActive:(UIApplication *)application {
    
58.     // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    
59. }
    
60. 
    
61. 
    
62. - (void)applicationWillTerminate:(UIApplication *)application {
    
63.     // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    
64. }
    
65. 
    
66. 
    
67. @end

24.     //NSString *url = @"widget://index.html";
    
25.     NSString *name = @"index";
    
26.     APIWindowContainer *windowContainer = [APIWindowContainer windowContainerWithAttribute:@{@"url":url, @"name":name}];
    
27.     [windowContainer startLoad];
    
28.    
    
29.     UIViewController *vc=windowContainer;//[[UIViewController alloc] init];
    
30.     UINavigationController *nav=[[UINavigationController alloc] initWithRootViewController:vc];
    
31.    
    
32.     return nav;
    
33. }

症状是显示白屏，代码跟踪的话，发现Index.html是正常加载，webViewDidFinishLoad 事件也有正常收到。
希望大神帮忙查看一下，感谢。

好好分析下index.html中的代码，什么情况下会导致白屏，找到具体原因。
