Customcell.xib size is 300X100
Here my output
My xib file as below
please help me to solve problem

Answer 1

if(cell == nil)
{
NSArray *outlets = [NSArray arrayWithArray:[[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:self options:nil]];
for(id obj in outlets)
{
if([obj isKindOfClass:[UITableViewCell class]])
{
cell = (CustomCell *)obj;
}
}
}
If your CustomCell is made via XIB then Write this Code where your cell is nil.
EDIT:-
This may be the cause - I think you haven't changed your CustomCell's class name. Follow these steps -
Take a XIB with name CustomCell.xib then delete its view.
Take a UITableViewCell and set its height and structure according to you.
Select File's Owner and change its class name to CustomCell, Same thing do with UITableViewCell... select it and change its class name to CustomCell.
Now connect all subView's IBOutLets.
Note:- Select IBOutLets by right clicking on UITableViewCell not from File's Owner.

Answer 2

Do the following in viewDidLoad
- (void)viewDidLoad
{
[super viewDidLoad];
UINib *nib = [UINib nibWithNibName:#"Customcell" bundle:nil];
[[self tableView] registerNib:nib forCellReuseIdentifier:#"CustomCell"];
}

Answer 3

If the cell is designed in a nib then you need to load the cell from the nib.
This actually has support in UIKit since iOS 5
What you need to do is register your nib with the UITableView.
- (void)viewDidLoad
{
[super viewDidLoad];
[self.tableView registerNib:[UINib nibWithNibName:#"Customcell" bundle:nil]
forCellReuseIdentifier:#"CustomCell"];
//...
}
Now your tableView:cellForRowAtIndexPath: just needs to look like this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CustomCell";
CustomCell *cell = (id)[tableView dequeueReusableCellWithIdentifier: CellIdentifier];
cell.cellDate.text = #"date";
cell.cellDescription.text = #"Description";
cell.cellImageview.image = [UIImage imageNamed:#"facebook.png"];
cell.cellTitle.text = #"Title";
return cell;
}
NB
Make sure to remember to set CustomCell as the reuseIdentifier in the xib
Some other observations
Really you should be using ARC for a new project.
#synthesize is implicit so not required in most cases
It's probably a bad idea to #import "CustomCell.h" in MasterViewController.h.
You should move this to the .m and use a forward declaration in the .h instead - #class CustomCell;
You also do not need to declare the backing ivars for properties as these will also be generated by the compiler e.g. you don't need to declare the following
#interface CustomCell : UITableViewCell {
IBOutlet UIImageView *cellImageview;
IBOutlet UILabel *cellTitle;
IBOutlet UILabel *cellDescription;
IBOutlet UILabel *cellDate;
}
