URL encode 用于将字符串以 URL 编码，具体代码如下：

+(NSString *)encodeString:(NSString *)unencodeString
{
    NSString * encodedString = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)unencodeString, NULL, (CFStringRef)@"!*'();:@&=+$,/?%#[]", kCFStringEncodingUTF8));
    return unencodeString;
}

-(NSString *)decodeString:(NSString *)encodedString
{
    NSString * decodedString = (__bridge_transfer NSString *)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL, (__bridge CFStringRef)encodedString, CFSTR(""),CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));
    return encodedString;
}

当然也可以不写方法体，直接复制方法内部的代码，把相关变量替换即可。
