UIDocumentInteractionControllerを

作成する



+ interactionControllerWithURL:




NSURL *URL＊以下は自動的に設定される（明示的に設定してもいい）

NSString *name NSString *UTI




UIを提供する



*readonlyNSArray *icons






- (void)setupDocumentControllerWithURL:(NSURL *)url { self.docInteractionController = [UIDocumentInteractionController interactionControllerWithURL:url]; self.docInteractionController.delegate = self;}


iPhone SDK 勉強会NSURL *fileURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:documents[indexPath.row] ofType:nil]];

[self setupDocumentControllerWithURL:fileURL];

cell.textLabel.text = [[fileURL path] lastPathComponent];NSInteger iconCount = [docInteractionController.icons count];if (iconCount > 0){ cell.imageView.image = [docInteractionController.icons objectAtIndex:iconCount - 1];}



プレビューを表示する

UIDocumentInteractionControllerのプレビュー




[self.docInteractionController presentPreviewAnimated:YES];

#pragma mark -#pragma mark UIDocumentInteractionControllerDelegate

- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)interactionController{ return self;}



Quick Look Frameworkを使用してプレビューを表示する


iPhone SDK 勉強会QLPreviewController *previewController = [[QLPreviewController alloc] init];previewController.dataSource = self;previewController.delegate = self; previewController.currentPreviewItemIndex = indexPath.row;

[self presentModalViewController:previewController animated:YES];[previewController release];


iPhone SDK 勉強会#pragma mark -#pragma mark QLPreviewControllerDataSource

// Returns the number of items that the preview controller should preview- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)previewController{ NSInteger numToPreview = 0; NSIndexPath *selectedIndexPath = [self.tableView indexPathForSelectedRow]; if (selectedIndexPath.section == 0) numToPreview = NUM_DOCS; else numToPreview = self.documentURLs.count; return numToPreview;}


iPhone SDK 勉強会// returns the item that the preview controller should preview- (id)previewController:(QLPreviewController *)previewController previewItemAtIndex:(NSInteger)index{ NSURL *fileURL = nil; NSIndexPath *selectedIndexPath = [self.tableView indexPathForSelectedRow]; if (selectedIndexPath.section == 0) { fileURL = [NSURL fileURLWithPath: [[NSBundle mainBundle]pathForResource:documents[index] ofType:nil]]; } else { fileURL = [self.documentURLs objectAtIndex:index]; } return fileURL;}



Quick Look Frameworkを使用するメリット

•モーダル以外の表示方法や遷移のアニメーションをカスタマイズ可能•連続してファイルを切り替えて表示することができる



Quick Look Frameworkでプレビュー可能なファイル


iPhone SDK 勉強会•iWork文書•Microsoft Office文書(Office 97以降)•Rich Text Format(RTF)文書•PDFファイル•画像•public.textタイプに準拠したUTI(Uniform Type Identifier)を持つテキストファイル(『Uniform Type Identifiers Reference』を参照)。•カンマ区切り(CSV)ファイル
