Load data into tableview form cells - objective-c

Question

I have a program where a UITableView contains custom cells loaded from nibs. These cells have textfields and a UIImage. I've been passing the information they contain to a custom class and encoding/decoding the class for data persistence. When I want to load the data, I put the information from the class into the cell. This works fine for 1 cell, but not for more than one. I've checked, and the classes are being written to file correctly.
This is my retrieval method:
//Fills an array if the file exists, otherwise returns nil
- (NSMutableArray*) findFile: (NSString *) add
{
if ([[NSFileManager defaultManager] fileExistsAtPath:[self saveFilePath:add]])
{
NSString *temp = [add stringByAppendingString:#"dat"];
namesIndexer = [[NSMutableArray alloc] initWithContentsOfFile:[self saveFilePath:temp]];
if (namesIndexer == nil) return nil;
NSMutableArray *thing = [NSMutableArray new];
for (NSString *place in namesIndexer)
{
temp = [add stringByAppendingString:place];
PTextHolder *p = [NSKeyedUnarchiver unarchiveObjectWithFile:[self saveFilePath:temp]];
[thing addObject:p];
}
return thing;
}
else
{
return nil;
}
}
Note that this is in a different class, and it calls the method from the holder.
//Returns a cell to be used at a row, populates it from the holder object
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *personCellId = #"personID";
UINib *nib = [UINib nibWithNibName:#"PersonCell" bundle:nil];
[tableView registerNib:nib forCellReuseIdentifier:personCellId];
PersonCell *cell = [tableView dequeueReusableCellWithIdentifier:personCellId];
cell.owner = tableView;
if (mineTable == nil) mineTable = tableView;
cell.delegated = formDataStorage;
[formDataStorage putWhatShouldBeInThisCellForThisRowInIt:cell:(int*)indexPath.row];
cell.currentRow = [[NSNumber alloc] initWithInt:indexPath.row];
return cell;
}
Here's the method it calls:
- (void) putWhatShouldBeInThisCellForThisRowInIt: (PersonCell *) someCell: (int *) someRow
{
if ((NSUInteger) someRow >= cake.count)
{
NSLog(#"The cake has been undercooked");
return;
}
PTextHolder *temp = [cake objectAtIndex:(NSUInteger) someRow];
someCell.firstName.text = temp.first;
someCell.lastName.text = temp.last;
someCell.middleName.text = temp.middle;
someCell.suffixName.text = temp.suffix;
someCell.email.text = temp.email;
someCell.theSignature.image = temp.sig;
}
Anything look wrong here/would cause only one cell to be loaded?

Answer 1

I would check first the number of items in the array with
[array count]
, if the number of items is equal to 1, then the problem is as you guessed with the encoding/decoding.
If not, your code is right and the problem is with your code to load the cells.
By the way, why dont you store your array of "cellInfoClass" directly using:
[NSKeyedArchiver archiveRootObject:array toFile:filePath]
and retrieve directly the array.
I guess you already added the encoding/coding code to your class, if not is like that:
/**
* Returns an object initialized from data in a given unarchiver. (required)
*
* #param decoder: An unarchiver object.
*/
- (id)initWithCoder:(NSCoder *)coder {
if (self = [super init]) {
// If parent class also adopts NSCoding, replace [super init]
// with [super initWithCoder:decoder] to properly initialize.
[self setName:[coder decodeObjectForKey:#"name"]];
[self setId:[coder decodeIntForKey:#"id"]];
[self setDomain:[coder decodeObjectForKey:#"domain"]];
}
return self;
}
/**
* Encodes the receiver using a given archiver. (required)
* #param coder: An archiver object.
*/
- (void)encodeWithCoder:(NSCoder *)coder{
// If parent class also adopts NSCoding, include a call to
// [super encodeWithCoder:encoder] as the first statement.
[coder encodeObject:name forKey:#"name"];
[coder encodeInt:id forKey:#"id"];
[coder encodeObject:domain forKey:#"domain"];
}
