【参考方案1】：

用UIDocumentInteractionController

- (void)onOpenWith:(UIButton *)theButton path:(NSString *)path
   
    NSURL *URL = [NSURL fileURLWithPath:path];

    if (URL) 
        self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:URL];

        self.documentInteractionController.delegate = self;
        [self.documentInteractionController presentOptionsMenuFromRect:CGRectZero
                                              inView:theButton
                                            animated:YES];
    



#pragma mark - UIDocumentInteractionControllerDelegate

- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller

    return self;


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

    return self.view;


- (CGRect)documentInteractionControllerRectForPreview:(UIDocumentInteractionController *)controller

    return self.view.frame;
