界面跳转的时候，感觉反应有点迟钝,求解？

[ETmanwenhan]

Why is it so slow to jump from list to detail? The network request that was not involved in the jump?

@ETmanwenhan

if let url = URL(string: property.imgUrl), let data = NSData(contentsOf: url) { self.imageView?.image = UIImage(data: data as Data) }

this is why sometimes it delays the transition

[ETmanwenhan]

the network of Image download is synchronous. That's the reason for sometimes it delays the transition ?

@ETmanwenhan yep I think so.
