本文介绍如何使用UIDocumentInteractionController进行本地文件预览及第三方分享。包括控制器实例化、委托方法实现及调用预览和分享菜单的具体方法。

UIDocumentInteractionController本地查看文件

实例化一个UIDocumentInteractionController对象并遵守其delegate

@interface FileReviewController () <UIDocumentInteractionControllerDelegate>

@property (nonatomic, strong) UIDocumentInteractionController *DIController;

@end

NSURL *urlPath = [[NSBundle mainBundle] URLForResource:@"Jobs" withExtension:@"pdf" subdirectory:@"PDF.bundle"];
self.DIController = [UIDocumentInteractionController interactionControllerWithURL:urlPath];
self.DIController.delegate = self;

实现delegate

#pragma mark - UIDocumentInteractionControllerDelegate
- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller {
    return self;
}

- (UIView*)documentInteractionControllerViewForPreview:(UIDocumentInteractionController*)controll
