写AFN的人很强大...
我只能看到一些皮毛...
AFPercentEscapedStringFromString...
就是url encode方法...
NSString * queryWord = @"汉字&ssss";
NSString * escapedString1 = [queryWord stringByAddingPercentEscapesUsingEncoding:4];
NSString * escapedString2 = AFPercentEscapedStringFromString(queryWord);
NSString * urlStr1 = [NSString stringWithFormat:@"https://www.baidu.com/s?ie=UTF-8&wd=%@",escapedString1];
NSString * urlStr2 = [NSString stringWithFormat:@"https://www.baidu.com/s?ie=UTF-8&wd=%@",escapedString2];
NSLog(@"urlStr1 == %@ \n urlStr2 == %@",urlStr1,urlStr2);
// urlStr1 == https://www.baidu.com/s?ie=UTF-8&wd=%E6%B1%89%E5%AD%97&ssss
// urlStr2 == https://www.baidu.com/s?ie=UTF-8&wd=%E6%B1%89%E5%AD%97%26ssss
AFQueryStringFromParameters...
将字典数据拼接成url的参数...
NSString * str = AFQueryStringFromParameters(@{@"name":@"000",@"phone":@"001"});
NSLog(@"####%@",str);
//name=000&phone=001
对AFNetworking的 Post，Get，Upload，Download简单封装...
定义YHHttps

其中

自己可以对里面的NSMutableURLRequest进行一些自定义的操作...
