SDWebImage,Swift:SDWebImageRefreshCached未解析的标识符

Question

奇怪......文档中的简单内容似乎与Swift无关.见下面的代码.使用Swift时"SDWebImageRefreshCached"究竟在哪里？

self.profileImageView.sd_setImageWithURL(profileImageUrl, placeholderImage:  UIImage(named: "default_profile_image"), options: SDWebImageRefreshCached)

Answer 1

在Swift中,枚举的暴露略有不同.

你会寻找SDWebImageOptions.RefreshCached,或.RefreshCached简称.

因此,您的代码行将是:

self.profileImageView.sd_setImageWithURL(profileImageUrl, placeholderImage:  UIImage(named: "default_profile_image"), options: .RefreshCached)
