50 字典/数组/字符串的序列化

 NSMutableDictionary *MDic = [[NSMutableDictionary alloc]init];
    MDic[@"SSID"] = ssid;
    MDic[@"Password"] = passWord;
    
    NSData *data = [NSJSONSerialization dataWithJSONObject:MDic options:NSJSONWritingPrettyPrinted error:nil];
    NSString *dataString = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
    
    const char *a = [dataString UTF8String];
    
    NSLog(@"************** %s",a);


通过更改 options 参数实现传递json格式的控制:  不需要格式化,将  NSJSONWritingPrettyPrinted 改为 kNilOptions
