To run the example project, clone the repo, and run carthage update from the Example directory first.

let embeddedView = URLEmbeddedView()


  • Default

  • No Image

  • No response


embeddedView.textProvider[.Title].font = .boldSystemFontOfSize(18)
embeddedView.textProvider[.Title].fontColor = .lightGrayColor()
embeddedView.textProvider[.Title].numberOfLines = 2
//You can use ".Title", ".Description", ".Domain" and ".NoDataTitle"

Data and Image Cache

You can get Open Graph Data with OGDataProvider.

OGDataProvider.shared.fetchOGData(urlString: String, completion: ((OpenGraph.Data, Error?) -> Void)? = nil) -> String?
OGDataProvider.shared.deleteOGData(urlString: String, completion: ((Error?) -> Void)? = nil)
OGDataProvider.shared.deleteOGData(_ ogData: OpenGraph.Data, completion: ((Error?) -> Void)? = nil)

You can configure time interval for next updating of OGData. Default is 10 days.

OGDataProvider.shared.updateInterval = 10.days

You can get UIImage with OGImageProvider.

OGImageProvider.shared.loadImage(urlString: String, completion: ((UIImage?, Error?) -> Void)? = nil) -> NSURLSessionDataTask?

Custom Data Cache implementation

Default cache feature is using Core Data. If you want to use other cache features, please implement cache manager with OGDataCacheManagerProtocol. For example, URLEmbeddedView has OGDataNoCacheManager that feature is not using cache. If you want to use that feature, you can use like this.

OGDataProvider.shared.cacheManager = OGDataNoCacheManager()

You can implement custom cache feature and use it like this.

class MemoryCacheManager: OGDataCacheManagerProtocol {
    // implementation of required methods

OGDataProvider.shared.cacheManager = MemoryCacheManager()

OpenGraph.Data Properties

public let imageUrl: URL?
public let pageDescription: String?
public let pageTitle: String?
public let pageType: String?
public let siteName: String?
public let sourceUrl: URL?
public let url: URL?


You can only use download feature of OGData with OpenGraphDataDownloader like this.

let urlString = ...
OpenGraphDataDownloader.shared.fetchOGData(urlString: urlString) { result in
    switch result {
    case let .success(data, isExpired):
        // do something
    case let .failure(error, isExpired):
        // do something

If you use OGDataProvider with OGDataNoCacheManager, it is almost same process.

OGDataProvider.shared.cacheManager = OGDataNoCacheManager()
let urlString = ...
OGDataProvider.shared.fetchOGData(urlString: urlString) { ogData, error in
    // do something



URLEmbeddedView is available through CocoaPods. To install it, simply add the following line to your Podfile:

# Uncomment the next line to define a global platform for your project
# platform :ios, '8.0'

target 'Your Project Name' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks

  # Pods for URLEmbeddedViewSample
  pod "URLEmbeddedView"


If you’re using Carthage, simply add NoticeObserveKit to your Cartfile:

github "marty-suzuki/URLEmbeddedView"

Use in Objective-C

#import <URLEmbeddedView/URLEmbeddedView-Swift.h>

- (void)viewDidLoad {
    [super viewDidLoad];
    URLEmbeddedView *embeddedView = [[URLEmbeddedView alloc] init];
    [self.view addSubView:embeddedView];
    [embeddedView loadURL:@"https://github.com/" completion:nil];

- (void)setUpdateInterval {
  [OGDataProvider sharedInstance].updateInterval = [NSNumber days:10];

- (void)fetchOpenGraphData {
  [[OGDataProvider sharedInstance] fetchOGDataWithUrlString:self.textView.text
                                            completion:^(OpenGraphData *data, NSError *error) {
      NSLog(@"OpenGraphData = %@", data);

Here is Objective-C sample.
