ios - About WebCache's sd_setImageWithURL with swift -

-

i'm using webcache swift.

when set string sd_setimagewithurl directly following, it's displayed correctly.

imageview?.sd_setimagewithurl(nsurl(string: "http://imgfp.hotp.jp/imgh/86/49/p018678649/p018678649_238.jpg"), placeholderimage: nil, options: sdwebimageoptions.cachememoryonly, completed: {[unowned self] (image: uiimage!, error: nserror!, type: sdimagecachetype, url: nsurl!) -> void in     ....

but, set following, it's not displayed..

if let imageurl:string = shop.img {     print(imageurl) // same above     self.imageview?.sd_setimagewithurl(nsurl(string: imageurl), placeholderimage: nil, options: sdwebimageoptions.cachememoryonly, completed: {[unowned self] (image: uiimage!, error: nserror!, type: sdimagecachetype, url: nsurl!) -> void in         .... }

what's wrong??

it's simple:

if let strimage = "http://imgfp.hotp.jp/imgh/86/49/p018678649/p018678649_238.jpg"{     self.imageview.sd_setimagewithurl(nsurl(string: strimage), completed: { (img, error, type, urls) in     }) }

use imageview.image display wherever want.
