objective c - Trouble with JSON parsing in iPhone App -


I am trying to do this work for a while, but I think that to see me I need to get out of my app, in my app, I'm getting JSON values ​​from a web server, and it is parsing it in my table view. 

  responseData = [NSData dataWithContentsOfURL: [NSURL URLWithString: @ "http: // MyServer / json"]]; NSString * responseString = [[NSString alloc] initWithData: response data encoding: NSUTF8StringEncoding]; NSDictionary * dict = [responseString JSONValue]; TheData = [Dial objectForKey: @ "Data"];

My only problem now is that 'data' is apparently an NSString, as far as I can see. When I call '[Data Count]' with my Visual Controller, the following error comes from GDB. 

  - [NSCF string count]: 0x6eb5380 sent to unknown selector for example  <  
 
  {"code ": 100," data ": [{** some object * /}]}   
 
 
 You can check that it has an NSString with:  
  [thedata isKindOfClass: [NSString class]]  
 
 You can also use NSString instead Why are you using NSCFString? NSString does not have the counting method! If you want the length of your string: 
 
  [the data length];

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
