推荐答案
这可以通过创建 QLPreviewView 实例嵌入在 NSPopover .
This can be achieved by creating a QLPreviewView instance embedded within a NSPopover.
然后，创建一个符合QLPreviewItem协议的NSObject子类，并像使用传统的QuickLook QLPreviewPanel一样在QLPreviewView上设置previewItem属性.
Then, create a NSObject subclass that conforms to the QLPreviewItem protocol and set the previewItem property on your QLPreviewView like when working with the traditional QuickLook QLPreviewPanel.
QLPreviewView *view = [[QLPreviewView alloc] initWithFrame:NSMakeRect(0, 0, 800, 100) style:QLPreviewViewStyleNormal];
JPQuickLookItem *item = [[JPQuickLookItem alloc] init];
item.previewItemURL = [NSURL fileURLWithPath:@"/Users/josh/Desktop/Test.png"];
item.previewItemTitle = @"Test.png";
view.previewItem = item;
我已经创建了一个示例Swift实现此处.
