1： // 给所有的Key排序
    NSArray *keys = [[parDic allKeys] sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {
        return [(NSString *)obj1 compare:obj2];
    }];

    NSMutableString *parame = [NSMutableString string];
    // 拼接
    for(NSUInteger i=0; i<[keys count]; i++) {
        NSString *key = [keys objectAtIndex:i];

        if ([key isEqualToString:TJJ_TAG_MARKET]) {
            continue;
        }
        [parame appendFormat:@"%@=%@&",key,[parDic objectForKey:key]];

}

2：sign 是给所有的key，value 拼接后，加密，就是sign

3：//url编码
- (NSString*)urlEncodedString:(NSString *)string
{
    NSString * encodedString = (__bridge_transfer NSString*) CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (__bridge CFStringRef)string, NULL, (__bridge CFStringRef)@"!*'();:@&=+$,/?%#[]", kCFStringEncodingUTF8 );
    if (encodedString) {
        return encodedString;
    }
    return @"";
}
