A spreadsheet view that have header/footer

TAXHeaderSheet

A spreadsheet view that have header/footer

##Requirements

iOS 6.0 or later

##Dependency

TAXSpreadSheet 0.2.0 or later

##Installation via CocoaPods

pod 'TAXHeaderSheet'

##Usage

Import header

#import "TAXHeaderSheet.h"

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

TAXHeaderSheet *headerSheet = [[TAXHeaderSheet alloc] initWithFrame:CGRectMake(0.0. 0.0. 100.0, 100.0)];
[headerSheet registerClass:[UICollectionViewCell class] forCellInAllSectionWithReuseIdentifier:@"Cell"];

Set metrics of the sheet via properties.

headerSheet.numberOfRowsOfBody = 30;
headerSheet.numberOfColumnsOfBody = 20;

headerSheet.numberOfRowsOfHeader = 1;
headerSheet.numberOfRowsOfFooter = 2;
headerSheet.numberOfColumnsOfHeader = 1;
headerSheet.numberOfColumnsOfFooter = 1;

headerSheet.sizeForCell = CGSizeMake(50.0, 20.0);
headerSheet.widthOfHeaderCell = 50.0;
headerSheet.widthOfFooterCell = 50.0;
headerSheet.heightOfHeaderCell = 20.0;
headerSheet.heightOfFooterCell = 20.0;
    
headerSheet.heightOfHeader = headerSheet.heightOfHeaderCell * 
headerSheet.numberOfRowsOfHeader;
headerSheet.heightOfFooter = headerSheet.heightOfFooterCell * headerSheet.numberOfRowsOfFooter;
headerSheet.widthOfHeader = headerSheet.widthOfHeaderCell * headerSheet.numberOfColumnsOfHeader;
headerSheet.widthOfFooter = headerSheet.widthOfFooterCell * headerSheet.numberOfColumnsOfFooter;

or by implementing delegate methods eg. headerSheet:heightAtRow:ofSectionType: There is priority for cell height/width: Header > Footer > Body > Property.

Set DataSource and Delegate objects and implement those methods.

- (UICollectionViewCell*)headerSheet:(TAXHeaderSheet *)headerSheet cellAtRow:(NSUInteger)row column:(NSUInteger)column inSectionType:(TAXHeaderSheetSectionType)sectionType
{
    TAXLabelCell *cell = [headerSheet dequeueReusableCellInSectionType:sectionType withReuseIdentifier:CellIdentifier forRow:row column:column];
    // Customize cell.
    return cell;
}

You should return dequeued UICollectionViewCell subclass in headerSheet:cellAtRow:column:inSectionType

##Customize

###Use custom views for separators.

You can use custom UICollectionReusableView subclass for separators. You should register class and dequeue view from HeaderSheet. In case of not using view, return nil.

- (UICollectionReusableView *)headerSheet:(TAXHeaderSheet *)headerSheet separatorViewOfSeparatorType:(TAXHeaderSheetSeparatorType)separatorType
{
    UICollectionReusableView *view = [headerSheet dequeueReusableSeparatorViewOfSeparatorType:separatorType withReuseIdentifier:@"Separator"];
    view.backgroundColor = [UIColor blueColor];
    return view;
}

###Use custom views for inter-row/column of each section.

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 *)headerSheet:(TAXHeaderSheet *)headerSheet interRowViewInSectionType:(TAXHeaderSheetSectionType)sectionType belowRow:(NSUInteger)row;
{
	if (row == 0) {
		UICollectionReusableView *view = [spreadSheet dequeueReusableInterRowViewWithIdentifier:@"View" belowRow:row];
		return view;
	} else {
		return nil;
	}
}
