Question

到目前为止，我已经完成并将http://mobiforge.com/developing/story/importing-exporting-documents-ios实施到我的项目中。但这没有任何作用。我试图让它在受支持的应用程序中打开任何文件。

我已经在我的.h和.m中声明了。

.h
UIDocumentInteractionController *documentController;
@property (retain) UIDocumentInteractionController *documentController;

和

.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    [cellTapSound play];
    [self.tableView deselectRowAtIndexPath:indexPath animated:NO];

    [self openDocumentIn];

}

-(void)openDocumentIn {
    NSString * filePath = self.directoryPath = @"/var/mobile/Documents/downloads";
    documentController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:filePath]];
    documentController.delegate = self;
    [documentController retain];
    documentController.UTI = @"public.deb"  @"public.zip" @"public.text" @"com.apple.quicktime-movie" @"com.adobe.pdf";
    [documentController presentOpenInMenuFromRect:CGRectZero
                                           inView:self.view
                                         animated:YES];
}

-(void)documentInteractionController:(UIDocumentInteractionController *)controller
       willBeginSendingToApplication:(NSString *)application {

}

-(void)documentInteractionController:(UIDocumentInteractionController *)controller
          didEndSendingToApplication:(NSString *)application {

}

-(void)documentInteractionControllerDidDismissOpenInMenu:
(UIDocumentInteractionController *)controller {

}

任何帮助或指导将不胜感激。

所以我设法让它工作，但唯一没有发生的事情，是我选择打开的任何应用程序，它不会显示该文件。 Dropbox例如。以下是我更新的半工作代码。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    [cellTapSound play];
    [self.tableView deselectRowAtIndexPath:indexPath animated:NO];


    NSString *filePath = [directoryContents objectAtIndex:indexPath.row];

    UIDocumentInteractionController *interactionController = [[UIDocumentInteractionController alloc] init];
    [interactionController setURL:[NSURL fileURLWithPath:filePath]];
    [interactionController setUTI:@"public.filename-extension"];

    [interactionController setDelegate:self];
    [interactionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];


}

我想我需要在这里的某处宣布一些东西，只是不知道是什么。

-(void)documentInteractionController:(UIDocumentInteractionController *)controller
       willBeginSendingToApplication:(NSString *)application {

}


-(void)documentInteractionController:(UIDocumentInteractionController *)controller
          didEndSendingToApplication:(NSString *)application {

}

再次坚持，任何想法？

出于愚蠢的运气，我得到了它的工作:)发表以下答案。

虽然没有人在这里回答，但我希望这有助于其他人。

这是什么使它适合我。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    [cellTapSound play];
    [self.tableView deselectRowAtIndexPath:indexPath animated:NO];


    NSString *fileName = [directoryContents objectAtIndex:indexPath.row];

    NSString *path;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    path = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"my downloads"];
    path = [path stringByAppendingPathComponent:fileName];

    documentController = [[UIDocumentInteractionController alloc] init];
    documentController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:path]];

    [documentController setDelegate:self];
    [documentController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
    [documentController retain];
}
