    <p>You cannot put <code>UICollectionViewCell</code> directly into the <code>UiCollectionView</code> if you are using <code>Xib</code> file. Its possible only in storyboard. Add a <code>UICollectionViewCell</code> into a separate Xib file. Give your class name. Then register either class or xib before the collection view appears</p> <pre><code> [self.collectionView registerClass:[CollectionViewCell class] forCellWithReuseIdentifier:CELL_ID]; </code></pre> <p>Typically this is done in <code>viewDidLoad</code>.</p> <p>This is the implementation of a custom <code>UICollectionViewCell</code> with out using <code>Xib</code> </p> <pre><code> @implementation CollectionViewCell @synthesize imageView = _imageView; - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { self.backgroundColor = [UIColor whiteColor]; self.layer.shadowColor = [UIColor blackColor].CGColor; self.layer.shadowRadius = 5.0f; self.layer.shadowOffset = CGSizeMake(2.0f, 2.0f); self.layer.shadowOpacity = 0.5f; // Selected background view UIView *backgroundView = [[UIView alloc]initWithFrame:self.bounds]; backgroundView.layer.borderColor = [[UIColor colorWithRed:0.529 green:0.808 blue:0.922 alpha:1]CGColor]; backgroundView.layer.borderWidth = 10.0f; self.selectedBackgroundView = backgroundView; // set content view CGRect frame = CGRectMake(self.bounds.origin.x+5, self.bounds.origin.y+5, self.bounds.size.width-10, self.bounds.size.height-10); UIImageView *imageView = [[UIImageView alloc] initWithFrame:frame]; self.imageView = imageView; [imageView release]; self.imageView.contentMode = UIViewContentModeScaleAspectFill ; self.imageView.clipsToBounds = YES; [self.contentView addSubview:self.imageView]; } return self; } </code></pre>

    1. COwhat would you do if you are using a xib for which you assign a class? I have a UICollectionViewCell class as the custom class of my cell xib. i registerNib withNibName firCellWithResueIdentifier in viewDidLoad (again xib is linked/connected to a cell class). can i combine a xib layout with extra customization done in code using my cell class? it doesn't look like the straight up flow will invoke initWithFrame on a class if you just register the nib. do i have to register both the nib and class with my collection view?

    3. CO@towpse What NAQ said is right. Register the nib. Then for additional customization use initWithCoder or awakeFromNib of your custom cell (in cell.m)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
