Unwanted Behaviour of UICollectionView - ios

Question

I am trying to display some text in UICollection view. But i am getting the error that
Property cell label not fount on object of type
UICOllectionViewCell
.h file
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController<UICollectionViewDataSource,UICollectionViewDelegate>
#end
.m file
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
return 1;
}
-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
return 10;
}
-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
NSString *cellIdentifier =#"cell";
UICollectionViewCell* cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
cell.cellLabel.text = #"Sample Text";
return cell;
}
#end
I have already set the delgate methods of UICollectionView.
Here is the Screenshot of Error

Answer 1

First note that even if you have a custom cell you are dequeing your collection view cell to a custom one :
UICollectionViewCell* cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
In compile time the compiler doesn't know you are trying to use your custom cell, therefore that property doesn't exist.
Be sure that you:
Created a custom UICollectionViewCell that has your cellLabel property
That you registered your cell via code OR you used your cell identifier in the Interface Builder
That you imported your cell and you are using it in cellForItemAtIndexPath

Answer 2

Do you have your cellLabel outlet set in interface builder?
If NO then make one.
You should have something like this in your cell's .h file:
#property (weak, nonatomic) IBOutlet UILabel *cellLabel;
then later you really just need to do this:
cell.cellLabel.text = #"";
You can also make a label like this,
UILabel *cellLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 10, cell.bounds.size.width, 40)]; //custom size
[cell.contentView addSubview:cellLabel];
and use it like
cell.cellLabel.text = #"Sample Text";
There are tutorial on UICollectionView you can have a look on this link.
