在Swift中从JSON解码base64_encode图像

您必须将字典值从AnyObject强制转换为String。您还必须使用.IgnoreUnknownCharacters选项对字符串数据进行解码。这样尝试

if let enpredImage = json["image"] as? String,    imageData =  NSData(base64EnpredString: enpredImage, options: .IgnoreUnknownCharacters),    image = UIImage(data: imageData) {    print(image.size)}
