问题 I'm using Kingfisher to show image from url, but my endpoint requires a Authorization header. How to use these kind of url with Kingfisher or SDWebImage in iOS? 回答1: With Kingfisher you need to make a request modifier (of type AnyModifier ) and pass it as a parameter in the options part of the .kf.setImage method, and then use the trailing closure to actually set the image. Example: import Kingfisher let modifier = AnyModifier { request in var r = request // replace "Access-Token" with the

Kingfisher and swift 3 - cannot set image with url

由 隐身守侯 提交于 2019-12-04 17:21:24
Checking the documentation and the migration guide, I should be able to set a new image using this code: imageView.kf.setImage(with:url ...) but actually I cannot find this method in the library, I only see: imageView.kf.setImage(with:Resource... ) I don't know exactly how this resource shoud work though since I cannot find anything in the documentation.
