是否可以加载 .ai 文件并以编程方式打开它们?

这是我尝试过的:

- (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:

在此处输入图像描述

这工作得很好..但我不想改变扩展。任何人都可以帮助我更多。

更新答案:

- (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;
}

这与菜单选项一起显示,但与选项 BUMP 一起显示。它仅适用于设备

如果将 Illustrator 文件保存为 .eps 文件,则可以提取矢量细节并将其重新用作 CAShapeLayer 上的路径,但对于复杂的形状并不简单。

这些链接应该会有所帮助:

一定要在 Github 上搜索 SVGKit。

希望有帮助。荣耀归于反对者。
