Objective c 线程1:AppDelegate.m文件中的断点1.3错误

我的AppDelegate.m文件中出现运行时错误；该项目编译良好，但不会显示在iOS模拟器中。在该文件中，我得到一个绿色箭头，表示Thread1:Breakpoint1.3错误，我无法理解

当它完成运行时，我得到一个指向这一行的堆栈跟踪，但没有发现代码有任何错误。我已经把问题所在的行注释掉了。你能告诉我怎么了吗

#import "WhereamiAppDelegate.h"

#import "WhereamiViewController.h"

@implementation WhereamiAppDelegate

@synthesize window = _window;
@synthesize viewController = _viewController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
  self.viewController = [[WhereamiViewController alloc] initWithNibName:@"WhereamiViewController" bundle:nil];
  self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible]; // Thread 1: breakpoint 1.3
    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:.
}

检查您的xib文件中是否有已删除但仍链接的门店：

我想首先要检查的是根视图控制器的xib文件

检查您的xib文件是否仍链接着已删除的插座：

非常感谢；这正是问题所在！我有一个名称错误的插座，我一删除它，它就工作了。再次感谢！非常感谢你；这正是问题所在！我有一个名称错误的插座，我一删除它，它就工作了。再次感谢！
