无法使用UIDocumentPickerViewController选择页面文件 [英] Unable to pick pages file with UIDocumentPickerViewController

问题描述

我正在使用UIDocumentPickerViewController来选择文档.以下是指定的UTI:

I'm using UIDocumentPickerViewController for picking document. Below are the specified UTIs :

NSArray *types = @[(NSString*)kUTTypeImage,(NSString*)kUTTypeSpreadsheet,(NSString*)kUTTypePresentation,(NSString*)kUTTypePDF,(NSString*)kUTTypeRTF,(NSString*)kUTTypePlainText,(NSString*)kUTTypeText];

UIDocumentPickerViewController *dpvc = [[UIDocumentPickerViewController alloc] initWithDocumentTypes:types inMode:UIDocumentPickerModeImport];

从页面应用程序创建的文件(页面文件)显示为灰色，无法选择.但是WhatsApp文档选择器允许选择相同的文件.我是否缺少任何必需的UTI?

The files created from pages app (pages file) are grayed out and unable to pick. But WhatsApp document picker allowed to pick the same files. Am I missing any required UTI ?

我的应用程序:

更新

com.apple.iwork.pages.sffpages可以解决我设备上的页面文件，但不适用于icloud驱动器上的文件.呈现文档选择器的完整代码为:

com.apple.iwork.pages.sffpages did the trick for pages files on my device, but not working for the files on icloud drive. The complete code to present document picker is:

-(IBAction)showDocumentPicker:(id)sender
{
    NSArray *types = @[(NSString*)kUTTypeImage,(NSString*)kUTTypeSpreadsheet,(NSString*)kUTTypePresentation,(NSString*)kUTTypePDF,(NSString*)kUTTypeRTF,(NSString*)kUTTypePlainText,(NSString*)kUTTypeText, @"com.apple.iwork.pages.sffpages"];

    UIDocumentPickerViewController *dpvc = [[UIDocumentPickerViewController alloc] initWithDocumentTypes:types inMode:UIDocumentPickerModeImport];

    dpvc.delegate = self;

    //colorFromHex 4285f4
    [[UINavigationBar appearance] setTintColor:[UIColor colorWithRed:66.0/255.0 green:133.0/255.0 blue:244.0/255.0 alpha:1.0]];

    [self presentViewController:dpvc animated:YES completion:nil];
}

推荐答案

实际上，Pages文件有2种不同类型，可以是捆绑包或单个文件，我认为您希望应用程序同时处理这两种文件.

Actually, there are 2 different types for Pages files, it could be a bundle or a single file, and I think that you want your app to handle both.

对应的UTI是com.apple.iwork.pages.sffpages和com.apple.iwork.pages.pages.

导入iWork文件的代码示例:

Example of code to import iWork files:

NSArray *types = @[@"com.apple.iwork.pages.sffpages", @"com.apple.iwork.pages.pages", @"com.apple.iwork.numbers.numbers", @"com.apple.iwork.keynote.key"];

UIDocumentPickerViewController *dpvc = [[UIDocumentPickerViewController alloc] initWithDocumentTypes:types inMode:UIDocumentPickerModeImport];

如果您在使用UIDocumentPickerViewController时仍然遇到问题，我还建议您观看此WWDC会话: https://developer.apple.com/videos/play/wwdc2018/216
