IOS-将基于代码的界面转换为基于故事板的界面 [英] IOS-Convert code-based interface to Storyboard based interface

问题描述

我引用了一个使用代码创建界面而不是故事板文件的 IOS 项目.但是我的项目是使用故事板来构建用户界面.现在，我所有的文件都编译得很好，但就是不运行.我不断收到线程 1:信号 SIGABRT"错误.

I am referencing a IOS project that use code to create the interface rather than storyboard file. But my project is using storyboard to build the user interface. Right Now, all my file compile pretty well, but just do not run. I keep getting "Thread 1:signal SIGABRT" error.

以下是我的项目文件:

AppleDelegate.h

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;


@end

AppDelegate.m

#import "AppDelegate.h"
#import "DetectionViewModel.h"
#import "ViewController.h"
#import "RscMgr.h"


@interface AppDelegate ()

@end

@implementation AppDelegate{
@private
UIWindow* _mainWindow;
RscMgr* _serialManager;
ViewController* _viewController;
}


- (BOOL)application:(UIApplication *)application  didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
_serialManager = [[RscMgr alloc] init];

DetectionViewModel* detectionViewModel = [[DetectionViewModel alloc]   initWithSerialManager: _serialManager];
_viewController = [[ViewController alloc] initWithViewModel: detectionViewModel];

return YES;
}

- (void)applicationWillResignActive:(UIApplication *)application {
// 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.
// Use this method to pause ongoing tasks, disable timers, and throttle down    OpenGL ES frame rates. Games should use this method to pause the game.
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
// 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.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
// 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.
}

- (void)applicationWillTerminate:(UIApplication *)application {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

And I did add the storyboard file name into the info list

推荐答案

在我看来，故事板文件可能没有添加到构建目标中，因此在启动时无法找到

It looks to me like perhaps the storyboard file was not added to the build target, so it can't be found at launch time
