DYMRollingBanner

DYMRollingBanner is a clean and easy-to-use banner rolling control for your app's homepage screen which need to show some rolling banners.

Why

Why do I write this ? Well...actually, I've been searching for a scrolling banner view at github for a while, but no luck since some of the code I found are too old to support Autolayout, others don't scrolls infinitely... none of them satisfied me. Then, I decided to do it myself, to write a good one...and here you go...

Features

Infinite scrolling, which mean it return to show the first banner when ended with the last one.
Supports both local and remote images.
Paused on dragging and resumes on releasing when it's auto rolling.
Implemented a memory cache which makes it lightning fast and less memory consuming.
Block based event handling.
100% compatible with AutoLayout.
Writen with clean code and very easy to use.

Installation

(from CocoaPods)

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like DYMRollingBanner in your projects. Simply add the following line to your Podfile:

pod 'DYMRollingBanner', '~> 2.1.4'

(direct installation)

Just copy these source files into you project:

DYMRollingBannerVC.h
DYMRollingBannerVC.m
DYMBannerVC.h
DYMBannerVC.m
DYMBannerPool.h
DYMBannerPool.m

Usage

Unlike many other banner scrolling controls, DYMRollingBanner doesn't use UIScrollingView or its subclasses UITableview or UICollectionView, instead it take full advantage of UIPageViewController which is natually an INFINITE controller.

To integrate DYMRollingBanner, firstly, you need to copy the assciated files into your project, and import DYMRollingBannerVC.h file:

#import <DYMRollingBanner/DYMRollingBannerVC.h>

Secondly, Create a DYMRollingBannerVC object.

DYMRollingBannerVC      *_rollingBannerVC;

_rollingBannerVC = [DYMRollingBannerVC new];

Then, add the DYMRollingBannerVC object as the child view controller of the host controller.

[self addChildViewController:_rollingBannerVC];
[self.view addSubview:_rollingBannerVC.view];
    
    // The code below lays out the _rollingBannerVC's view using Masonry
    [_rollingBannerVC.view mas_makeConstraints:^(MASConstraintMaker *make) {
        make.leading.top.and.right.equalTo(self.view);
        make.height.equalTo(@200);
    }];
    
 [_rollingBannerVC didMoveToParentViewController:self];

Finally, feed it with you image URLs or UIImage object:

_rollingBannerVC.rollingInterval = 5;
_rollingBannerVC.rollingImages = @[@"http://www.drpsychmom.com/wp-content/uploads/2014/10/large_4278047231.jpg"
                                , @"https://c2.staticflickr.com/4/3345/5832660048_55f8b0935b.jpg"
                                , @"http://epaper.syd.com.cn/sywb/res/1/20080108/42241199752656275.jpg"
                                , [UIImage imageNamed:@"001"]    // Local Image
                                , [UIImage imageNamed:@"002"]    // Locak Image
                                ];
        
  [_rollingBannerVC addBannerTapHandler:^(NSInteger whichIndex) {
        NSLog(@"banner tapped, index = %@", @(whichIndex));
  }];
        
  [_rollingBannerVC startRolling];

And you are good to go!

Associated Classes

Notice

DYMRollingBanner uses SDWebImage for image downloading, so if you install DYMRollingBanner using cocopods, this library will be installed too, but if you prefer to manually copy the source files into your project, make sure also to include SDWebImage.
