Question

我有一个iPad应用程序，需要从iCloud获取PDF和视频，在Web视图中打开PDF，然后将索引路径保存在文档中，然后需要在另一个视图中打开它并保存在文档中。 / p>

到目前为止，我可以打开iCloud并使用以下代码下载：

(IBAction)openIcloud:(id)sender {

    UIDocumentPickerViewController *documentPicker = [[UIDocumentPickerViewController alloc] initWithDocumentTypes:@[@"public.data"] inMode:UIDocumentPickerModeImport];

    documentPicker.delegate = self;

    documentPicker.modalPresentationStyle = UIModalPresentationFormSheet;

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

}

您非常接近，只是缺少这样的东西

#pragma mark - iCloud files
- (void)documentPicker:(UIDocumentPickerViewController *)controller   didPickDocumentAtURL:(NSURL *)url {
  if (controller.documentPickerMode == UIDocumentPickerModeImport) {


  docController =[UIDocumentInteractionController interactionControllerWithURL: url];
    //NSURL *url = [NSURL fileURLWithPath:documentPickerMode];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [MywebWiev setUserInteractionEnabled:YES];
    [MywebWiev setDelegate:self];
    MywebWiev.scalesPageToFit = YES;
    [MywebWiev loadRequest:requestObj];

}

}

 - (IBAction)Pdf001:(id)sender {
UIDocumentPickerViewController *documentPicker =   [[UIDocumentPickerViewController alloc] initWithDocumentTypes:@[@"public.data"]   inMode:UIDocumentPickerModeImport];

documentPicker.delegate = self;

documentPicker.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:documentPicker animated:YES completion:nil];


}

 remember call <UIDocumentPickerDelegate,UIWebViewDelegate>
