暫時(shí)蒙圈的我先上幾個(gè)可用的code 但是具體區(qū)別 im not sure
第一段：Xcode自帶 包含base64和gbk
? ? ? ? NSStringEncoding gbkEncoding1 =CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingGB_18030_2000);
? ? ? ? NSString *result1 = [[NSString alloc] initWithData:responseObject? encoding:NSUTF8StringEncoding];
? ? ? ? NSData*decodedData = [[NSDataalloc]initWithBase64EncodedString:result1options:0];
? ? ? ? NSString*jsonstring = [[NSStringalloc]initWithData:decodedDataencoding:gbkEncoding1];
? ? ? ? NSData *jsondata = [jsonstring dataUsingEncoding:NSUTF8StringEncoding];
? ? ? ? NSMutableDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsondata options:NSJSONReadingMutableContainers error:nil];
第二段：Xcode自帶
? ? ? ? NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];
第三段：SBJson
NSString *responseString = [NSString stringWithString:[string stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
? ? NSDictionary*request_Json = [stringJSONValue];
