更新CoreData对象无法正常工作 [英] update CoreData Object not working correct

问题描述

我是iOS开发/ CoreData的新手，已经在寻找我的特定问题的答案，但是还没有找到答案。

我有一个TableView与我数据库中的一些对象。每个对象都有一个属性名称。如果我打开一个对象的详细信息视图，然后使用后退按钮返回tableView，则一切正常。如果我不对名称 TextField进行任何更改，然后按完成按钮返回到我的tableView，它也将起作用。我在名称文本字段中进行了一些更改后，立即收到以下错误消息：

无效的更新：第0部分中的行数无效。更新（9）之后在现有节中包含的行数必须等于更新（9）之前在该节中包含的行数，加上或减去从该节插入或删除的行数（0插入，删除1条），然后加上或减去移入或移出该部分的行数（移入0，移出0）。

为什么要删除一个对象？

这是我的DetailsS​​taticTableViewController.m的代码：

  #import WeinStaticTableViewController.h 
 #import Wein.h 
 #import JSMToolBox.h 
 
 @interface WeinStaticTableViewController （）
 
 @end 
 
 @implementation WeinStaticTableViewController 
 @synthesize nameTextView; 
 @synthesize landTextView; 
 @synthesize herstellerTextView; 
 @synthesize wein = _wein; 
 
-（id）initWithStyle：（UITableViewStyle）style 
 {
 self = [super initWithStyle：style]; 
 if（self）{
 //自定义初始化
} 
返回self; 
} 
 
-（void）viewDidLoad 
 {
 [super viewDidLoad]; 
 
 if（self.wein！= nil）{
 self.nameTextView.text = self.wein.name; 
} 
} 
 
-（void）viewDidDisappear：（BOOL）动画
 {
 [[JSMCoreDataHelpermanagedObjectContext]回滚]; 
 [super viewDidDisappear：animated]; 
} 
 
-（void）didReceiveMemoryWarning 
 {
 [super didReceiveMemoryWarning]; 
 //处理所有可以重新创建的资源。 
 [self setNameTextView：nil]; 
 [self setLandTextView：nil]; 
 [self setHerstellerTextView：nil]; 
 self.wein = nil; 
} 
 
-（IBAction）barButtonItemDonePressed：（id）sender 
 {
 NSLog（@％s，__PRETTY_FUNCTION__）; 
 if（self.wein！= nil）{
 self.wein.name = self.nameTextView.text; 
 [JSMCoreDataHelper saveManagedObjectContext：[JSMCoreDataHelpermanagedObjectContext]]； 
} 
 [self.navigationController popViewControllerAnimated：YES]; 
} 
 @end 
  

这是我的JSMCoreDataHelper.m的代码：

  #import JSMCoreDataHelper.h 
 
 @implementation JSMCoreDataHelper

} 
返回是； 
} 
 
 @end 
  

最后是numberOfSections和numberOfRowsInSection我的MainTableViewController：

 -（NSInteger）numberOfSectionsInTableView：（UITableView *）tableView 
 {
 //返回节数。 
返回[[[self.fetchedResultsController部分]计数]; 
} 
 
-（NSInteger）tableView：（UITableView *）tableView numberOfRowsInSection：（NSInteger）section 
 {
 //返回该部分的行数。 
返回[[[[self.fetchedResultsController部分] objectAtIndex：section] numberOfObjects]; 
} 
  

任何线索都可以帮助...谢谢！

使用NSFetchedResultsController在我的代码中，这与您用于管理CoreData的代码配合得很好。

 NSError * error; 
 if（！[[[self fetchedResultsController] performFetch：& error]）{
 //更新以适当地处理错误。 
 NSLog（@未解决的错误％@，％@，错误，[错误userInfo]）; 
出口（-1）; //失败

I'm new to iOS development/CoreData and have searched for an answer to my specific problem, but haven't found one yet.

I have a TableView with some Objects from my database. Each of the objects has an attribute "name". If I open the details view of one of the objects and go back to the tableView with the "back" Button everything works fine. It also works if I do no changes to the "name" TextField and press the "done" Button to get back to my tableView. As soon as I do some changes in the "name" TextField I get this error:

Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (9) must be equal to the number of rows contained in that section before the update (9), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).

Why is there an object being deleted?

Here is the code of my DetailsStaticTableViewController.m:

#import "WeinStaticTableViewController.h"
#import "Wein.h"
#import "JSMToolBox.h"

@interface WeinStaticTableViewController ()

@end

@implementation WeinStaticTableViewController
@synthesize nameTextView;
@synthesize landTextView;
@synthesize herstellerTextView;
@synthesize wein = _wein;

- (id)initWithStyle:(UITableViewStyle)style
{
   self = [super initWithStyle:style];
   if (self) {
     // Custom initialization
   }
   return self;
}

- (void)viewDidLoad
{
   [super viewDidLoad];

   if (self.wein != nil) {
      self.nameTextView.text = self.wein.name;
   }
}

- (void) viewDidDisappear:(BOOL)animated
{
   [[JSMCoreDataHelper managedObjectContext] rollback];
   [super viewDidDisappear:animated];
}

- (void)didReceiveMemoryWarning
{
   [super didReceiveMemoryWarning];
   // Dispose of any resources that can be recreated.
   [self setNameTextView:nil];
   [self setLandTextView:nil];
   [self setHerstellerTextView:nil];
   self.wein = nil;
}

- (IBAction)barButtonItemDonePressed:(id)sender
{
   NSLog(@"%s", __PRETTY_FUNCTION__);
   if (self.wein != nil) {
       self.wein.name = self.nameTextView.text;
       [JSMCoreDataHelper saveManagedObjectContext:[JSMCoreDataHelper managedObjectContext]];
   }
   [self.navigationController popViewControllerAnimated:YES];
}
@end

Here is the code of my JSMCoreDataHelper.m:

#import "JSMCoreDataHelper.h"

@implementation JSMCoreDataHelper

+ (NSString*) directoryForDatabaseFilename
{
   return [NSHomeDirectory() stringByAppendingString:@"/Library/Private Documents"];
}

+ (NSString*) databaseFileName
{
   return @"database.sqlite";
}

+ (NSManagedObjectContext*) managedObjectContext
{
  static NSManagedObjectContext *managedObjectContext;
  if (managedObjectContext != nil) {
      return managedObjectContext;
  }

  NSError *error;
  // Verzeichnis unter dem das Datenbank-File abgespeichert werden soll, wird neu erzeugt, falls es noch nicht existiert.
  [[NSFileManager defaultManager] createDirectoryAtPath:[JSMCoreDataHelper directoryForDatabaseFilename] withIntermediateDirectories:YES attributes:nil error:&error];

  if (error) {
      NSLog(@"Fehler: %@", error.localizedDescription);
      return nil;
  }

  NSString *path = [NSString stringWithFormat:@"%@/%@", [JSMCoreDataHelper directoryForDatabaseFilename], [JSMCoreDataHelper databaseFileName]];
  NSURL *url = [NSURL fileURLWithPath:path];

  NSManagedObjectModel *managedModel = [NSManagedObjectModel mergedModelFromBundles:nil];

  NSPersistentStoreCoordinator *storeCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:managedModel];

  if (! [storeCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:url options:nil error:&error]) {
      NSLog(@"Fehler: %@", error.localizedDescription);
      return nil;
  }

  managedObjectContext = [[NSManagedObjectContext alloc] init];
  managedObjectContext.persistentStoreCoordinator = storeCoordinator;

  return managedObjectContext;
}

+ (id) insertManagedObjectOfClass: (Class) aClass inManagedObjectContext: (NSManagedObjectContext*) managedObjectContext
{
   NSManagedObject *managedObject = [NSEntityDescription insertNewObjectForEntityForName:NSStringFromClass(aClass) inManagedObjectContext:managedObjectContext];
   return managedObject;
}

+ (BOOL) saveManagedObjectContext: (NSManagedObjectContext*) managedObjectContext
{
   NSError *error;
   if (! [managedObjectContext save:&error]) {
       NSLog(@"Fehler: %@", error.localizedDescription);
       return NO;
   }
   return YES;
}

+ (NSArray*) fetchEntitiesForClass: (Class) aClass withPredicate: (NSPredicate*) predicate inManagedObjectContext: (NSManagedObjectContext*) managedObjectContext
{
   NSError *error;
   NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
   NSEntityDescription *entityDescription = [NSEntityDescription entityForName:NSStringFromClass(aClass) inManagedObjectContext:managedObjectContext];
   fetchRequest.entity = entityDescription;
   fetchRequest.predicate = predicate;

   NSArray *items = [managedObjectContext executeFetchRequest:fetchRequest error:&error];
   if (error) {
       NSLog(@"Fehler: %@", error.localizedDescription);
       return nil;
   }
   return items;
}

+ (BOOL) performFetchOnFetchedResultsController: (NSFetchedResultsController*) fetchedResultsController
{
   NSError *error;
   if (! [fetchedResultsController performFetch:&error]) {
       NSLog(@"Fehler: %@", error.localizedDescription);
       return NO;
   }
   return YES;
}

@end

And finally the numberOfSections and numberOfRowsInSection of my MainTableViewController:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
   // Return the number of sections.
   return [[self.fetchedResultsController sections] count];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
   // Return the number of rows in the section.
   return [[[self.fetchedResultsController sections] objectAtIndex:section] numberOfObjects];
}

Any clue could help...thank you !

Heres my code using a NSFetchedResultsController, this works fine with your code for managing CoreData.

Hope this helps.

    NSError *error;
    if (![[self fetchedResultsController] performFetch:&error]) {
        // Update to handle the error appropriately.
        NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
        exit(-1);  // Fail
    }
