Cannot load data in custom cells in a UITableView - iphone

Question

Please help me with UITableViewCells.
I have followed many tutorials and sites but didn't get my problem solved.
I have tried to make a simpleCustomCells app but data are not loaded in the table view.
1.I have a table view controller:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
CustomCell *cell = (CustomCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *nib = [NSArray arrayWithArray:[[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:self options:nil]];
for(id obj in nib)
{
if([obj isKindOfClass:[UITableViewCell class]])
{
cell = (CustomCell *)obj;
}
}
}
cell.label.text = #"hello";
return cell;
}
Also tried
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
"within if(cell==nill)"
2.I have created CustomCell : UITableViewCell with only a UILabel outlet. Changed CustomCell.xib identifier's name.
When I run this app I get this kind of error:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSObject 0x71627f0> setValue:forUndefinedKey:]: this class
is not key value coding-compliant for the key label.
Please Help me with this issue, where am I going wrong.

Answer 1

Ok, I think I got where you are getting stuck.
Step 1 : Disconnect the outlet UILabel from the xib file.
Step 2 : Go to your xib file and you will see your objects list on the left hand side of the xib file.
Step 3 : Take your mouse pointer just below where objects is written. You will find Custom Cell written.
Step 4 : Press ctrl and drag it to the label and now Connect the Outlet to label.
Step 5 : Clean your program and Run it again.
All the best. If you still have doubts, I will elaborate. :)

Answer 2

I think you should add like this, I hope it works
static NSString *CellIdentifier = #"Cell";
customcellCell *cell = (customcellCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; <- set your customclass in this line.
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"customviewcell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.label.text = #"hello";
return cell;

Use following way :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
ContactListCell *contactCell;
NSString *contactCellID = [NSString stringWithFormat:#"ContactCell%d%d",indexPath.row,indexPath.section];
contactCell = (ContactListCell *)[tableView dequeueReusableCellWithIdentifier:contactCellID];
if(!contactCell) {
contactCell = [[ContactListCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:contactCellID];
contactCellID = nil;
}
strName = #"First name";
contactCell.lblFirstName.text = [strName capitalizedString];
return contactCell;
}
For Custom cell .h file
#interface ContactListCell : UITableViewCell {
UILabel *lblFirstName;
}
#property (strong, nonatomic) UILabel *lblFirstName;
#end
For Custom cell .m file
#implementation ContactListCell
#synthesize lblFirstName;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
lblFirstName = [[UILabel alloc]initWithFrame:CGRectMake(kxiPadFirstNameCellLandscape, kyiPadFirstNameCellLandscape, kiPadFirstNameCellWidthLandscape, kiPadFirstNameCellHeightLandscape)];
lblFirstName.backgroundColor= [UIColor clearColor];
lblFirstName.numberOfLines = 0;
lblFirstName.textColor = kCustomCellFontColor;
[self.contentView addSubview:lblFirstName];
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
#end

Why not give you're cell an identifier and instantiate it with dequewithreusableidentifier?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"Cell";
CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[AanbodTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.Label.text =#"Hello"
return cell;
}
i would also refer to this very good tutorial http://www.appcoda.com/customize-table-view-cells-for-uitableview/
