ios - 加载 Adob​​e Illustrator(.ai) 文件

Question

是否可以加载 .ai 文件并以编程方式打开它们？

这是我试过的:

- (IBAction)openDocument:(id)sender
{
    QLPreviewController *previewController = [[QLPreviewController alloc] init];
    [previewController setDataSource:self];
    [previewController setDelegate:self];
    [self presentModalViewController:previewController animated:YES];
}

- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)controller
{
    return 1;
}

- (id <QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index
{
    return [[NSBundle mainBundle] URLForResource:@"CNW EXPLODED1" withExtension:@"ai"];
}

但是输出是这样的:

有一种方法可以做到这一点。那就是将该 ai 的扩展名更改为 pdf 并加载它，如下所示，

- (IBAction)openDocument:(id)sender
{
    QLPreviewController *previewController = [[QLPreviewController alloc] init];
    [previewController setDataSource:self];
    [previewController setDelegate:self];
    [self presentModalViewController:previewController animated:YES];
}
- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)controller
{
    return 1;
}
- (id <QLPreviewItem>)previewController:(QLPreviewController *)controller previewItemAtIndex:(NSInteger)index
{
    return [[NSBundle mainBundle] URLForResource:@"CNW EXPLODED1" withExtension:@"pdf"];
}

输出:

这工作得很好..但我不想更改扩展名。谁能帮助我更多。

更新的答案:

- (IBAction)openDocument:(id)sender
{
    UIButton *button = (UIButton *)sender;
    NSURL *URL = [[NSBundle mainBundle] URLForResource:@"CNW EXPLODED1" withExtension:@"ai"];

    if (URL) {
        // Initialize Document Interaction Controller
        self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:URL];

        // Configure Document Interaction Controller
        [self.documentInteractionController setDelegate:self];

        // Present Open In Menu
        [self.documentInteractionController presentOpenInMenuFromRect:[button frame] inView:self.view animated:YES];
    }
}


- (UIViewController *) documentInteractionControllerViewControllerForPreview: (UIDocumentInteractionController *) controller {
    return self;
}

这显示有菜单选项，但有 BUMP 选项。它仅适用于设备
