さまざまなコンポーネントを含むプログラムがありますが、コンパイルすると、毎回シグナル SIGBART が発生します。私のコードの主な目的は、ユーザーが移動したときにブール値を変更し、ボタンがタップされたときにテキストを変数に設定し、さまざまなボタンを押して実行/禁止する文字列を設定することです。私のコードは以下の通りです：

ViewController.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController
@synthesize mapView;
@synthesize dodont;
@synthesize reminders;

- (void)viewDidLoad
{
    [super viewDidLoad];
    mapView.showsUserLocation = YES;
    on = @"don't";
    dodont.text = on;
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)mapView:(MKMapView *)mapView
didUpdateUserLocation:
(MKUserLocation *)userLocation
{
    move = TRUE;
}

- (IBAction)enable:(id)sender {
    on = @"do";
}

- (IBAction)disable:(id)sender {
    on = @"don't";
}
- (IBAction)save:(id)sender {
    content = reminders.text;
}
@end

ViewController.h

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>

NSString *on;
BOOL move= FALSE;
NSString *content;

@interface ViewController : UIViewController {
    MKMapView *mapview;
}
@property (weak, nonatomic) IBOutlet MKMapView *mapView;

- (IBAction)enable:(id)sender;

- (IBAction)disable:(id)sender;
@property (weak, nonatomic) IBOutlet UILabel *dodont;
- (IBAction)save:(id)sender;
@property (strong, nonatomic) IBOutlet UITextView *reminders;

@end

AppDelegate.m

#import "AppDelegate.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    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:.
}

@end

AppDelegate.h

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@end

iOS/Objective-C では、変数は次のように宣言する必要があります。

@interface クラス名:SuperClass

{

  • #ここで変数を宣言

}

  • ここで変数のプロパティを設定します

  • ここでメソッドを宣言します

@終わり

そして、クラス宣言の上で変数を宣言しています。

また、applicationdidFinishLaunching メソッドでアプリケーションのウィンドウを初期化していません。これを試して、ロードしたいビューでウィンドウ rootviewcontroller を設定してください。

こんなものを入れたくないですか：

NSString *on;
BOOL move= FALSE;
NSString *content;

あなたの.hファイルの間@interfaceと@end中？

また、忘れないでください: @property (nonatomic, strong)for 各プロパティ (BOOL 値には強力なパラメーターがありません)。

インターフェイスは次のようになります。

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>

@interface ViewController : UIViewController {
    MKMapView *mapview;
}

@property (strong, nonatomic) NSString *on;
@property (nonatomic) BOOL move;
@property (strong, nonatomic) NSString *content;
@property (weak, nonatomic) IBOutlet MKMapView *mapView;
@property (strong, nonatomic) IBOutlet UITextView *reminders;
@property (weak, nonatomic) IBOutlet UILabel *dodont;

- (IBAction)enable:(id)sender;    
- (IBAction)disable:(id)sender;
- (IBAction)save:(id)sender;

@end
