It's a Pinterest style scroll view designed to be used similar to a UITableView.
It supports Portrait and Landscape orientations.
I built this as a hack to show my friends. Any suggestions or improvements are very welcome!
Coming soon... A fully functional demo app.
It's the equivalent of UITableViewCell
It implements base methods for configuring data and calculating height
Note: You should subclass this!
I use this in my iPhone/iPad app, Lunchbox.
Fully ARC compatible now
Here's an example of creating an instance of PSCollectionView
self.collectionView = [[PSCollectionView alloc] initWithFrame:CGRectZero];
self.collectionView.delegate = self; // This is for UIScrollViewDelegate
self.collectionView.collectionViewDelegate = self;
self.collectionView.collectionViewDataSource = self;
self.collectionView.backgroundColor = [UIColor clearColor];
self.collectionView.autoresizingMask = ~UIViewAutoresizingNone;
Setting number of columns
// Specify number of columns for both iPhone and iPad
if (isDeviceIPad()) {
self.collectionView.numColsPortrait = 3;
self.collectionView.numColsLandscape = 4;
} else {
self.collectionView.numColsPortrait = 1;
self.collectionView.numColsLandscape = 2;
}
Add a header view
UIView *headerView = ...
self.collectionView.headerView = headerView;
Add a footer view
UIView *footerView = ...
self.collectionView.footerView = footerView;
Reloading Data [self.collectionView reloadData];
Delegate and DataSource
- (Class)collectionView:(PSCollectionView *)collectionView cellClassForRowAtIndex:(NSInteger)index {
return [PSCollectionViewCell class];
}
- (NSInteger)numberOfRowsInCollectionView:(PSCollectionView *)collectionView {
return 0;
}
- (UIView *)collectionView:(PSCollectionView *)collectionView cellForRowAtIndex:(NSInteger)index {
return nil;
}
- (CGFloat)collectionView:(PSCollectionView *)collectionView heightForRowAtIndex:(NSInteger)index {
return 0.0;
}
