내 문제 : 모든 기능이 제대로 작동하지만 TahDoodle (큰 괴상한 목장에서 배울 수있는 프로그램) (Objective-C 프로그래밍 : The Big Nerd Ranch Guide) ., 프로그램 충돌 본인은 "누출"악기에보고했다 많은 누수를 보았다하지만 난 그것을 해결하는 방법을 몰라 여기 파일을 열면 TahDoodle이 작동을 멈 춥니 다.
내 코드입니다 :..BNRDocument.m
#import "BNRDocument.h"
@implementation BNRDocument
# pragma mark - NSDocument Overrides
- (id)init
{
self = [super init];
if (self) {
// Add your subclass-specific initialization here.
// If an error occurs here, return nil.
}
return self;
}
- (NSString *)windowNibName
{
// Override returning the nib file name of the document
// If you need to use a subclass of NSWindowController or if your document supports multiple NSWindowControllers, you should remove this method and override -makeWindowControllers instead.
return @"BNRDocument";
}
# pragma mark - Actions
- (IBAction)createNewItem:(id)sender
{
// Falls es noch kein Array gibt, erstellen Sie einfach
// eines, in dem unsere neue Aufgabe gespeichert wird
if (!toDoItems) {
toDoItems = [[NSMutableArray alloc]init];
}
[toDoItems addObject:@"New Item"];
// -reloadDate aktualisiert die Tabellenansicht und fordert von
// dataSource (das in diesem Fall zufällig dieses BNRDocument ist)
// neue Daten zur Darstellung an
[itemTableView reloadData];
// -updateChangeCount: teilt der Anwendung mit, ob im Dokument
// ungespeicherte Änderungen vorhanden sind oder nicht.
// NSChangeDone kennzeichnet das Dokument als ungespeichert
[self updateChangeCount:NSChangeDone];
}
# pragma mark - Data Source Methods

// Diese Tabellenansicht soll die todoItems darstellen,
// und somit ist die Zahl der Einträge in der Tabellenansicht
// gleich der Zahl der Objekte im Array
return [toDoItems count];
}
- (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
{
// Gibt das Element aus todoItems zurück, das mit der Zelle
// korrespodiert, die die Tabellenansicht darstellen will
return [toDoItems objectAtIndex:row];
}
- (void)tableView:(NSTableView *)tableView
setObjectValue:(id)object
forTableColumn:(NSTableColumn *)tableColumn
row:(NSInteger)row
{
// Ändert der Benutzer ein To-do-Element in der Tabellenansicht
// wird das totoItems-Array aktualisiert
[toDoItems replaceObjectAtIndex:row withObject:object];
// Dann wird das Dokument gekennzeichnet, es habe
// ungespeicherte Änderungen
[self updateChangeCount:NSChangeDone];
}
- (void)windowControllerDidLoadNib:(NSWindowController *)aController
{
[super windowControllerDidLoadNib:aController];
// Add any code here that needs to be executed once the windowController has loaded the document's window.
}
- (NSData *)dataOfType:(NSString *)typeName error:(NSError **)outError
{
// Diese Methode wird beim Speichern unseres Dokuments aufgerufen
// Wir sollen dafür sorgen, dass der Aufrufer ein NSData-Objekt bekommt,
// das unsere Daten umhüllt um sie auf Festplatte schreiben zu können
// Falls es kein Array gibt, schreibn wir fürs Erste ein leeres Array
if (!toDoItems) {
toDoItems = [[NSMutableArray alloc]init];
}
// Packt unser toDoItems-Array in ein NS Data-Objekt
NSData *data = [NSPropertyListSerialization dataWithPropertyList:toDoItems
format:NSPropertyListXMLFormat_v1_0
options:0
error:outError];
// Gibt das neu gepackte NSData-Objekt zurück
return data;
}
- (BOOL)readFromData:(NSData *)data ofType:(NSString *)typeName error:(NSError **)outError
{
// Diese Methode wird aufgerufen, wenn ein Dokument geladen wird
// Wir bekommen ein NSData-Objekt und sollen daraus unsere Daten ziehen
// Extrahiert ToDoItems
toDoItems = [NSPropertyListSerialization propertyListWithData:data
options:NSPropertyListMutableContainers
format:NULL
error:outError];
// Gibt unabhängig vom obigen Aufruf Erfolg oder Misslingen zurück
return (toDoItems !=nil);
}

나는 5 회 alle 그 코드 부분을 빨간색과 내 여자 친구는 2 번했다. 그러나이 책에 쓰여있는 모든 내용은이 게시물의 수정 사항을 적용한 것입니다. http://forums.bignerdranch.com/viewtopic.php?f=160&t=3494
나를 도울 수 있다면 좋을 것입니다. 주셔서 감사합니다 :)

을하지만 그게 무슨 뜻인지 모르겠어요. 하지만 그것은 읽기 오류가 아닌 것 같습니다.

하나 밖에없는 브레이크 포인트는 여기에 있습니다 : :

// Gibt das Element aus todoItems zurück, das mit der Zelle

도구 방법은 다음로드해야 파일의 내용입니다 예외 이유를 찾는 것은 매우 좋습니다. 고마워. 모든 "반환"에서 수동 중단 점을 설정했습니다.
