加载Adobe Illustrator(.ai)文件

是否有可能加载.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"];
}

但输出是这样的:

在这里输入图像描述


有一种方法可以做到这一点。 这正在改变这个AI的扩展到PDF和加载,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"];
}

OUTPUT:

在这里输入图像描述

这是完美的工作..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;
}

这显示菜单选项,但与选项BUMP。 它仅适用于设备

如果将Illustrator文件保存为.eps文件,但可以提取矢量细节,并将它们重新用作CAShapeLayer上的路径,但对于复杂的形状不是直接的。

这些链接应该有帮助:

绝对在Github上搜索SVGKit。

希望有所帮助。 荣耀归于downvoters。
