DCScrollView

DCScrollView is an extension of UIScrollView that scrolling through the content, the title scrolls with a delay like Etsy app for iOS.

Requirements

• iOS 4.3+
• ARC

If your project's target is iOS 8.0+, use PageController. PageController has high performance than DCScrollView. DCScrollView controls [UIView], PageController controls [UIViewController].

Used in Production

• ヤフオク!

Installation

There are two ways to use this in your project:

• Copy DCScrollView/*.{h.m} into your project

• Install with CocoaPods to write Podfile

platform :ios
pod 'DCScrollView'

Usage

Set Delegate, DataSource

DCScrollView uses a simple methodology. It defines a delegate and a data source, its client implement. DCScrollViewDelegate and DCScrollViewDataSource are like UITableViewDelegate and UITableViewDatasource.

Reload

Reset cells and redisplays visible cells. Current page keep visible after reloading.

- (void)reloadData;

Remove Cache

If UIViewController received memory warnings, control to clear the memory that DCScrollView has.

- (void)clearData;

Example

• import DCScrollView.h
• implement DCScrollViewDataSource and DCScrollViewDelegate's methods

UIViewController

#import "DCScrollView.h"

@interface ExampleViewController ()

<DCScrollViewDataSource, DCScrollViewDelegate>

@end

@implementation ExampleViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    DCScrollView *scrollView = [[DCScrollView alloc]initWithFrame:self.view.bounds];
    scrollView.dataSource = self;
    scrollView.delegate = self;
}

- (NSInteger)numberOfCellsInDCScrollView:(DCScrollView *)scrollView
{
    return 10;
}

- (DCScrollViewCell *)dcscrollView:(DCScrollView *)scrollView cellAtIndex:(NSInteger)index
{
    NSString *identifier = @"Cell";
    DCScrollViewCell *cell = [scrollView dequeueReusableCellWithIdentifier:identifier];
    if (!cell) {
        cell  = [[DCScrollViewCell alloc] initWithReuseIdentifier:identifier];
    }

    return cell;
}
