Installation

The easiest way to get started is to use CocoaPods. Just add the following line to your Podfile:

pod 'VENSeparatorView', '~> 1.0.0'

General Usage

Import VENSeparatorView.h

Create an instance of UISeparatorView or a UISeparatorView subclass using its initWithFrame:topLineSeparatorType:bottomLineSeparatorType initializer and add it as a subview.

VENSeparatorType options are:

VENSeparatorTypeStraight,
VENSeparatorTypeJagged,
VENSeparatorTypeNone

UITableViewCell Provider

Making jagged cells in a UITableView is simple using the included VENSeparatorTableViewCellProvider

Import #import "VENSeparatorTableViewCellProvider.h" in your UITableViewDataSource and conform this class to the VENSeparatorTableViewCellProviderDelegate protocol isCellJaggedAtIndexPath: method.

Example:

// Specifies that all cells with odd row index are jagged.
- (BOOL)isCellJaggedAtIndexPath:(NSIndexPath *)indexPath
{
	return (indexPath.row % 2);
}

Set your UITableView's separatorStyle property to UITableViewCellSeparatorStyleNone

Create a VENSeparatorTableViewCellProvider property:

@property (nonatomic, strong) VENSeparatorTableViewCellProvider *separatorProvider;

In this class's init method, or in the viewDidLoad method if this class is a UIViewController subclass, instantiate the VENSeparatorTableViewCellProvider property using its initWithStrokeColor:fillColor:delegate: method.

self.separatorProvider = [[VENSeparatorTableViewCellProvider alloc] initWithStrokeColor:[UIColor grayColor]
                                                                              fillColor:[UIColor lightGrayColor]
                                                                               delegate:self];

At the end of your data source's tableView:cellForRowAtIndexPath: method apply separators to the UITableViewCell with the VENSeparatorTableViewCellProvider's applySeparatorsToCell:atIndexPath:inTableView:cellHeight:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell;
    // ...

    [self.separatorProvider applySeparatorsToCell:cell atIndexPath:indexPath inTableView:tableView cellHeight:0];
    return cell;
}
