I'm having trouble running my basic iPhone application (while going through the Stanford iTunes CS193p lectures) in the iOS simulator.
I've been searching for a while (both Google and SO), but unable to find a solution so far. There are many similar bugs, but the solutions don't seem to fix this.
In Xcode I click "run". It compiles and builds successfully, launches iOS simulator but it never gets to loading the app. Only the status bar at the top. With a black screen.
I've only written very basic code (following along with the lectures) and can't get past this problem.
To confuse matters more, I wrote a web wrapper
@interface CalculatorAppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions (NSDictionary *)launchOptions
// Override point for customization after application launch.
- (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:.
@interface CalculatorViewController : UIViewController
@property (weak, nonatomic) IBOutlet UILabel *display;
@synthesize display = _display;
- (IBAction)digitPressed:(UIButton *)sender
NSString *digit = [sender currentTitle];
NSLog(@"digit pressed = %@", digit);
Surprisingly, what worked for me was going to iOS Simulator menu, and pressing "Reset Content and Settings".
