정말 고민 중이며 다른 사람이 도울 수 있기를 바랍니다.코어 데이터 저장 후 사용자 정의 셀 레이블 텍스트가 겹칩니다.
코어 데이터를 사용하고 있고 fetchedResultsController를 사용하여 TableView를 채우고 있습니다. 셀 유형의 경우 사용자 지정을 사용하고 있습니다. 상세보기를 보완하는 셀을 선택한 후 필드 중 하나를 변경하고 저장을 눌러 테이블 뷰로 돌아갑니다. 문제는 이전 필드 텍스트가 아직 남아 있고 새 텍스트가 겹쳐져 있다는 것입니다.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
[self configureCell:cell atIndexPath:indexPath];
}
else {
// Cells all appear blank if I don't include the following line
[self configureCell:cell atIndexPath:indexPath];
Games *game = [self.fetchedResultsController objectAtIndexPath:indexPath];
UILabel *nwOpp = (UILabel *)[cell.contentView viewWithTag:401];
NSLog(@"nwOpp:%@", nwOpp.text);
nwOpp.text = [NSString stringWithFormat:@"%@", game.opponents.name];
UILabel *nwDate = (UILabel *)[cell.contentView viewWithTag:501];
NSLog(@"Date:%@", nwDate.text);
nwDate.text = [NSString stringWithFormat:@"%@ - %@" , [dateFormatter stringFromDate: game.date] , game.location];
UIImageView *nwImg2 = (UIImageView *)[cell.contentView viewWithTag:201];
nwImg2.image = game.opponents.image;
}
return cell;
}
- (void)configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath {
Games *game = [self.fetchedResultsController objectAtIndexPath:indexPath];
CGRect imageFrame = CGRectMake(70, 2, 20, 20);
UIImageView *customImage = [[UIImageView alloc] initWithFrame:imageFrame];
[customImage setContentMode:UIViewContentModeScaleAspectFill];
customImage.clipsToBounds = YES;
customImage.image = game.teams.image;
customImage.tag = 101;
[cell.contentView addSubview:customImage];
CGRect imageFrame2 = CGRectMake(230, 2, 20, 20);
UIImageView *customImage2 = [[UIImageView alloc] initWithFrame:imageFrame2];
[customImage2 setContentMode:UIViewContentModeScaleAspectFill];
customImage2.clipsToBounds = YES;
customImage2.image = game.opponents.image;
customImage2.tag = 201;
[cell.contentView addSubview:customImage2];
CGRect teamFrame = CGRectMake(0, 18, 140, 24);
UILabel *teamLabel = [[UILabel alloc] initWithFrame:teamFrame];
teamLabel.font = [UIFont boldSystemFontOfSize:14];
teamLabel.text = [NSString stringWithFormat:@"%@", game.teams.name];
teamLabel.textAlignment = NSTextAlignmentCenter;
teamLabel.tag = 301;
[cell.contentView addSubview:teamLabel];
CGRect versusFrame = CGRectMake(140, 18, 20, 24);
UILabel *versusLabel = [[UILabel alloc] initWithFrame:versusFrame];
versusLabel.font = [UIFont boldSystemFontOfSize:16];
versusLabel.text = @"vs";
versusLabel.textAlignment= NSTextAlignmentCenter;
[cell.contentView addSubview:versusLabel];
CGRect oppFrame = CGRectMake(160, 18, 140, 24);
UILabel *oppLabel = [[UILabel alloc] initWithFrame:oppFrame];
oppLabel.font = [UIFont boldSystemFontOfSize:14];
oppLabel.text = [NSString stringWithFormat:@"%@", game.opponents.name];
oppLabel.textAlignment = NSTextAlignmentCenter;
oppLabel.tag = 401;
[cell.contentView addSubview:oppLabel];
CGRect dateFrame = CGRectMake(10, 40, 300, 12);
UILabel *dateLabel = [[UILabel alloc] initWithFrame:dateFrame];
dateLabel.font = [UIFont systemFontOfSize:10];
dateLabel.text = [NSString stringWithFormat:@"%@ - %@" , [dateFormatter stringFromDate: game.date] , game.location];
dateLabel.textAlignment = NSTextAlignmentCenter;
dateLabel.tag = 501;
[cell.contentView addSubview:dateLabel];
}
나는 데이터 변경 저장 대리자 방법을 사용하고 있습니다 :
-(void)EditGameViewControllerDidSave {
NSError *error = nil;
NSManagedObjectContext *context = self.managedObjectContext;
if (![context save:&error]) {
NSLog(@"Error! %@", error);
}
[self.navigationController popViewControllerAnimated:YES];
[self.tableView reloadData];
}
FetchedResultsController 변경 :
-(void) controllerWillChangeContent:(NSFetchedResultsController *)controller {
[self.tableView beginUpdates];
}
-(void) controllerDidChangeContent:(NSFetchedResultsController *)controller {
[self.tableView endUpdates];
}
-(void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath {
UITableView *tableView = self.tableView;
switch (type) {
case NSFetchedResultsChangeInsert:
[tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade];
break;
case NSFetchedResultsChangeDelete:
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
break;
case NSFetchedResultsChangeUpdate:
[self configureCell:[tableView cellForRowAtIndexPath:indexPath] atIndexPath:indexPath];
break;
case NSFetchedResultsChangeMove:
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
[tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade];
break;
}
}
내 tableviewcontroller.m는 셀에 대한 다음과 같은 코드가 있습니다
