iOS 读取Excel 等文件

方法一：使用QuickLook.freamwork

    UIDocumentInteractionController *document = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:@"/Users/a502333921/Desktop/ブック2.xlsx"]];

    document.delegate = self;

    NSLog(@"%d",[document presentPreviewAnimated:YES]);

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

{

    return self;

}

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

{

    return self.view;

}

- (CGRect)documentInteractionControllerRectForPreview:(UIDocumentInteractionController*)controller

{

    returnself.view.frame;

}

//点击预览窗口的“Done”(完成)按钮时调用

- (void)documentInteractionControllerDidEndPreview:(UIDocumentInteractionController*)_controller

{

}

此方法弹框显示文件  也可以通过其他软件打开文档

方法2：

    QLPreviewController *previewoCntroller = [[QLPreviewController alloc] init];

    previewoCntroller.dataSource = self;

    [self presentViewController:previewoCntroller animated:YES completion:nil];

- (NSInteger) numberOfPreviewItemsInPreviewController: (QLPreviewController *) controller

{

   return1;

}

- (id <QLPreviewItem>)previewController: (QLPreviewController *)controller previewItemAtIndex:(NSInteger)index

{

    return [NSURLfileURLWithPath:@"/Users/a502333921/Desktop/ブック2.xlsx"];

}

问题：

当你加载Excel时候，可能会出现部分气泡中内容不显示等情况，请重新保存为xls格式文档！
