Use NSInteger as array index

Question

Have a happy year   I am having trouble with the following  First logic   Get json from server  Json value is always a number  Read plist into array  NSLog the array with index of the json value from server   My plist   Key     Type     Value Item 0  String   New York Item 1  String   Atlanta   My code   Get Json  NSString  url req   http   domain com index php                NSURLRequest  request    NSURLRequest requestWithURL  NSURL URLWithString url req                 NSData  response    NSURLConnection sendSynchronousRequest request                                                      returningResponse nil error nil                NSError  jsonParsingError   nil              NSDictionary  json    NSJSONSerialization JSONObjectWithData response                                                                       options 0 error  amp jsonParsingError                NSArray  cityArray    json objectForKey   city                for  NSDictionary  alert in pestoArray                    myLoc     alert objectForKey   location   integerValue                   Json is working just fine   Read plist and nslog the corresponding value   NSString  path     NSBundle mainBundle  pathForResource   townsList  ofType   plist     NSArray  arrayNo    NSArray alloc  initWithContentsOfFile path                NSLog   City     arrayNo myLoc      So far arrayNo myLoc  will return null but arrayNo 1  will return Atlanta   How can i use the integer value from JSON as an array index   Thank you   EDIT  Error output when using arrayNo myLoc  is   Indexing expression is invalid because subscript type  NSInteger     aka  int     is not an integral or Objective-C pointer type

According to the error message  you declared myLoc as a pointer to an NSInteger  NSInteger  myLoc  rather than an actual NSInteger  NSInteger myLoc   It needs to be the latter
