Swift
let str : NSString = CFURLCreateStringByAddingPercentEscapes(nil, dic, "!*‘();:@&=+$,/?%#[]" as CFString, nil, CFStringBuiltInEncodings.UTF8.rawValue)
//            let str : NSString = dic.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)! as NSString
//            let str : NSString = dic.addingPercentEscapes(using: String.Encoding.utf8.rawValue)!
//            let str : NSString = dic.addingPercentEncoding(withAllowedCharacters: NSCharacterSet(charactersIn:"`#%^{}\"[]|\\<> ").inverted)!

OC

//编码
- (NSString *)encode {
    CFStringRef strRef = CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)self, NULL, NULL, kCFStringEncodingUTF8);
    return (NSString *)CFBridgingRelease(strRef);
}

经过上面的编码即可加载出图片
