ios - Unable to write JSONValue into NSDictionary - JSON Framework not working -


I am using JSON to get feedback and then save it to NSDictionary I am trying. I am using the same code in about 12 clones of the same app and I am doing a great job. But, in one of my apps, I am unable to do this.

NSDictionary * resultDictionary = [jsonString JSONValue]; NSString * statusString = [resultsDictionary objectForKey: @ "status"];

This is a simple two line code and works well in general, but I do not know what is going on at this time. My JSON framework may not work properly. But I'm getting this in JSONValue : 

  {"status": "success", "data": [{"userName": "abc@gmail. Com "," first name ":" ABC "," last_name ":" xyz "," gender ":" male "," user id ": 1," membership status ":" active "," saldo ": 499 749, "Avatar": "No_photo.gif", "Unique Code": "abc234abc234", "Register": "abc543abc534", "email": "abc@gmail.com"}]   
  [___ NSCCC Stenstring Object Foreiki:] : Sent to the unknown selector  
 
 Because  the result is empty  
 Why is  the result data  empty? Any remedy?   
 
 
  [jsonString JSONValue];             P> 
 Apple has created a framework for converting Jason to use these approaches  
 Use this  
  NSDictionary * response = [NSJSONSerialization JSONObjectWithData: responseData option: kNilOptions error: & amp; Error];

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
