ios - Accessing NSDictionary retrieves an object instead of NSString -

i have nsdictionary fill json. looks great, , partially working me. setting property of class of type nsstring equal value key, oddly enough sets property equal object object being string value need.

the dictionary (printed description):

miscinfo: <__nsarrayi 0x7494ab0>( {   abbreviation = dr;   dateinactive = "";   description = drowsiness;   forqueue = 2430;   isadditive = 0;   isreserved = 1;   misccodetypestr = avr;   pluraldescription = "";   reserveddescription = drowsiness; } 

i setting on property so:

self.reactionname = [miscinfo valueforkeypath:@"description"]; 

which produces:

i've tried casting nsstring such as:

self.reactionname = (nsstring*)[allergenadversereaction valueforkeypath:@"description"]; 

but nothing gives. doing wrong?

miscinfo array containing dictionary,

self.reactionname = [[miscinfo objectatindex:0] objectforkey:@"description"]; 

would give result expect. or, using modern array , dictionary subscripting syntax:

self.reactionname = miscinfo[0][@"description"]; 

---

remark: in code

self.reactionname = [miscinfo valueforkeypath:@"description"]; 

valueforkeypath applied each element of array, , array values returned. see in xcode debugger window.

this "feature" can useful, in general (as hot licks commented above) objectforkey right method value dictionary. and

self.reactionname = [miscinfo objectforkey:@"description"]; 

throws descriptive runtime exception if miscinfo not dictionary expected.
