我正在使用 iOS 5.1 sdk 开发我的应用程序，但“打开方式”不适用于 pptx、ppt、docx、xlsx。有人可以给我 info.plist 的设置吗？我使用 com.microsoft.word.doc、com.microsoft.excel.xls、com.microsoft.powerpoint.ppt 作为文档类型。

NSArray *extensionArray = [NSArray arrayWithObjects
"doc", @"docx", @"ppt", @"pptx", @"xls", @"xlsx",@"mp3",@"mp4",@"rft",@"rtf",@"pages",@"key",@"numbers",nil];
for (int i=0; i<[extensionArray count]; i++) {
NSString *fileExtension = [extensionArray objectAtIndex:i];
NSString *utiString = (__bridge NSString *)UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension,(__bridge CFStringRef)fileExtension,NULL);
NSLog(@"Extension: %@ UTI:%@",fileExtension,utiString);
}
