TAXSpreadSheet

A view that display cells like spreadsheet.

##Requirements

iOS 6.0 or later

##Installation via CocoaPods

pod 'TAXSpreadSheet'

##Usage

Import header

#import "TAXSpreadSheet.h"

Instantiate TAXSpreadSheet and register UICollectionViewCell or subclass for cells the same as UICollectionView.

TAXSpreadSheet *spreadSheet = [[TAXSpreadSheet alloc] initWithFrame:CGRectMake(0.0. 0.0. 100.0, 100.0)];
[spreadSheet registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:@"Cell"];

Set DataSource and Delegate objects and implement those methods.

- (NSUInteger)numberOfColumnsInSpreadSheet:(TAXSpreadSheet *)spreadSheet
{
    return 10;
}
    
- (NSUInteger)numberOfRowsInSpreadSheet:(TAXSpreadSheet *)spreadSheet
{
    return 20;
}
    
- (UICollectionViewCell *)spreadSheet:(TAXSpreadSheet *)spreadSheet cellAtRow:(NSUInteger)row column:(NSUInteger)column
{
    UICollectionViewCell *cell = [spreadSheet dequeueReusableCellWithReuseIdentifier:@"Cell" forRow:row column:column];

    // Customize cells.

    return cell;
}

You should return dequeued UICollectionViewCell subclass from SpreadSheet in spreadSheet:cellAtRow:column

##Customize

###Specifying individual metrics You can specify individual heights of row, width of column, inter-row/column spacing by implementing delegate methods. In case of using default value, return NSNotFound.

- (CGFloat)spreadSheet:(TAXSpreadSheet *)spreadSheet heightAtRow:(NSUInteger)row
{
	if (row == 0) {
		return 100.0;
	} else {
		return 50.0;
	}
}

###Use custom views for inter-row/column. You can use custom UICollectionReusableView subclass for inter-row/column by implementing delegate methods. You should register class and dequeue view from SpreadSheet. In case of not using view, return nil.

- (UICollectionReusableView *)spreadSheet:(TAXSpreadSheet *)spreadSheet interRowViewBelowRow:(NSUInteger)row
{
	if (row == 0) {
		UICollectionReusableView *view = [spreadSheet dequeueReusableInterRowViewWithIdentifier:@"View" belowRow:row];
		return view;
	} else {
		return nil;
	}
}
