개체를 UIViewController
을 통해 개체에 삽입해야하는 경우가 있습니다. 필자는 데이터베이스 모델 (엔티티 및 특성)을 설계했습니다. 엔티티를 UIViewController
을 통해 추가하려고합니다. appDelegate.m의 didFinishLaunchingwithOptions
메소드에 무엇을 추가해야합니까? 보기 컨트롤러를 통해 엔티티에 데이터 추가
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch
return YES;
}
그리고 TUTViewController
(내 자신의 뷰 컨트롤러 - UIViewController
)에 대한
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {

NSEntityDescription *entity = [[self.fetchedResultsController fetchRequest] entity];

NSString *stripped1 = [response stringByReplacingOccurrencesOfString:@"\r" withString:@""];
NSMutableArray *rows = [NSMutableArray arrayWithArray:[stripped1 componentsSeparatedByString:@"\n"]];
NSMutableArray *contentArray = [NSMutableArray arrayWithCapacity:[rows count]];
NSMutableArray *contentArray1 = [NSMutableArray arrayWithCapacity:[rows count]];
NSArray *components;
NSLog(@"count:%d",[rows count]);

continue;
}
components = [[rows objectAtIndex:i] componentsSeparatedByString:@","];

id y = [components objectAtIndex:1];
id z = [components objectAtIndex:2];
[contentArray addObject:[NSMutableDictionary dictionaryWithObjectsAndKeys:x,@"X",y,@"Y", nil]];

내가 빠진 것이 있습니까? 나는 오류와 함께 종료 해요 :
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '+entityForName: could not locate an NSManagedObjectModel for entity name 'FetalData''
