У меня есть текстовое поле, которое вводит пользователь, затем я сохраняю его с помощью NSKeyedArchiver и вытаскиваю его для просмотра на столе, но каждый раз, когда я вписываю что-то в текстовое поле и сохраняю его, оно заменяет первый элемент в ячейке.Я хочу добавить его в таблицу.
в NewEntry.m, где я сохраняю данные с помощью
- (IBAction)saveButton:(id)sender {
int i = selectedSegment.selectedSegmentIndex;
app = [[UIApplication sharedApplication] delegate];
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setInteger:i forKey:@"category"];
if (i == 0) {
// [userDefaults setObject:titlefield.text forKey: @"titlehomework"];
// [userDefaults setObject:detailstextfield.text forKey:@"detailshomework"];
NSMutableArray *contactArray;
contactArray = [[NSMutableArray alloc] init];
[contactArray addObject:titlefield.text];
[contactArray addObject:detailstextfield.text];
[NSKeyedArchiver archiveRootObject:
contactArray toFile:datafilePath];
}
else if(selectedSegment.selectedSegmentIndex == 1) {
[userDefaults setObject:titlefield.text forKey:@"titletextprojects"];
[userDefaults setObject:detailstextfield.text forKey:@"detailsprojects"];
}
else if (selectedSegment.selectedSegmentIndex == 2){
[userDefaults setObject:titlefield.text forKey:@"titletextappointments"];
[userDefaults setObject:detailstextfield.text forKey:@"detailsappointments"];
}
else if (selectedSegment.selectedSegmentIndex == 3){
[userDefaults setObject:titlefield.text forKey:@"titletextevents"];
[userDefaults setObject:detailstextfield.text forKey:@"detailsevents"];
}
else if (selectedSegment.selectedSegmentIndex == 4){
[userDefaults setObject:titlefield.text forKey:@"titletexttodolist"];
[userDefaults setObject:detailstextfield.text forKey:@"detailstodolist"];
}
/*[userDefaults synchronize];
titlefield.text =@" ";
detailstextfield.text =@" ";
NSLog(@"selected segment %i", i);*/
/* UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Task saved!" message:@"You're all done." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, selectedSegment.selectedSegmentIndex];
[alert show];*/
[[NSNotificationCenter defaultCenter] postNotificationName:@"ValuesChanged"
object:self];
[self dismissModalViewControllerAnimated:YES];
}
NewEntry ViewDidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
if (__managedObjectContext == nil)
{
__managedObjectContext = [(StaticTableAppDelegate *)[[UIApplication sharedApplication] delegate] managedObjectContext];
NSLog(@"After managedObjectContext_: %@", __managedObjectContext);
}
NSFileManager *filemgr;
NSString *docsDir;
NSArray *dirPaths;
filemgr = [NSFileManager defaultManager];
// Get the documents directory
dirPaths = NSSearchPathForDirectoriesInDomains(
NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = [dirPaths objectAtIndex:0];
// Build the path to the data file
datafilePath = [[NSString alloc] initWithString: [docsDir
stringByAppendingPathComponent: @"data.archive"]];
// Check if the file already exists
if ([filemgr fileExistsAtPath: datafilePath])
{
NSMutableArray *dataArray;
dataArray = [NSKeyedUnarchiver
unarchiveObjectWithFile: datafilePath];
//titlefield.text = [dataArray objectAtIndex:0];
// detailstextfield.text = [dataArray objectAtIndex:1];
}
}
новая запись ViewDidUnload:
- (void)viewDidUnload
{
[self setTitleTextfield:nil];
[self setCategory:nil];
[self setDetailstextfield:nil];
[self setTitlefield:nil];
[self setTitlefield:nil];
[self setSelectedSegment:nil];
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
А в контроллере таблицы я называю это здесь: tableview:
- (void)viewDidLoad
{
[super viewDidLoad];
// [self fetchRecords];
if(tablesubtitles == nil && tabledata == nil){
tablesubtitles = [[NSMutableArray alloc]init];
tabledata = [[NSMutableArray alloc] init];
}
NSFileManager *filemgr;
NSString *docsDir;
NSArray *dirPaths;
filemgr = [NSFileManager defaultManager];
// Get the documents directory
dirPaths = NSSearchPathForDirectoriesInDomains(
NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = [dirPaths objectAtIndex:0];
// Build the path to the data file
datafilePath = [[NSString alloc] initWithString: [docsDir
stringByAppendingPathComponent: @"data.archive"]];
// Check if the file already exists
if ([filemgr fileExistsAtPath: datafilePath])
{
NSMutableArray *dataArray;
dataArray = [NSKeyedUnarchiver
unarchiveObjectWithFile: datafilePath];
titlestring = [dataArray objectAtIndex:0 ];
detailsstring = [dataArray objectAtIndex:1];
[tabledata addObject:titlestring];
[tablesubtitles addObject:detailsstring];
}
}
и:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
UITableViewCell *cell = nil;
cell = [tableView dequeueReusableCellWithIdentifier:@"homeworkcell"];
if(cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"homework"];
}
NSString *cellValue = [tabledata objectAtIndex:indexPath.row];
NSString *subtitle = [tablesubtitles objectAtIndex:indexPath.row];
cell.textLabel.text= cellValue;
cell.detailTextLabel.text= subtitle;
cell.textLabel.font = [UIFont systemFontOfSize:14.0];
cell.textLabel.backgroundColor = [ UIColor clearColor];
cell.detailTextLabel.backgroundColor = [UIColor clearColor];
//[tabledata addObjectser.title];
//[tabledata addObject:user.detai/s];
//static NSString *CellIdentifier = @"Cell";
// Configure the cell.
//-----------------------------------------START----------------------------Set image of cell----
cellImage = [UIImage imageNamed:@"checkboxblank.png"];
cell.imageView.image = cellImage;
//--------------------------------------------END---------------------------end set image of cell--
return cell;
}
************* UPDATE ********** Таким образом, в saveButton должно быть:
NSMutableArray *contactArray;
contactArray = [NSKeyedUnarchiver
unarchiveObjectWithFile: datafilePath];
// contactArray = [[NSMutableArray alloc] init];
[contactArray addObject:titlefield.text];
[contactArray addObject:detailstextfield.text];
[NSKeyedArchiver archiveRootObject:
contactArray toFile:datafilePath];
// NSDictionary *stuff;
