Add multiple objects to NSMutableArray from file list

Question

I am having a Picker View for selecting states(or prefectures for Europe).The current method i am using to populate the Picker View is the following:

in viewDidLoad

_arrayNo = [[NSMutableArray alloc] init];
[_arrayNo addObject:@" AL "];
[_arrayNo addObject:@" AK "];
[_arrayNo addObject:@" AZ "];
[_arrayNo addObject:@" Other "];

and then the usual pickerView delegate and dataSource. With the above code i don't have any issues. But apparantly if i want to add many states/town(let't say over 100) the array method would become hard to maintain.

My question is can i load the states into the array from a list in a file which resides inside the Supporting files folder? For example a file containing:

AL
AK
AZ
AR
CA
...
WI
WV
WI
Other

Thanks in advance.

Yes. You load the file, parse the strings out of it (probably with componentsSeparatedByString:) and put them in an array.

You can have a .plist file with the list and then load the plist file root dictionary keys/values into your array.

Found it!

@property(nonatomic,retain) NSArray *arrayNo;


  NSString *path = [[NSBundle mainBundle] pathForResource:
                      @"townsList" ofType:@"plist"];
  _arrayNo= [[NSArray alloc] initWithContentsOfFile:path];

Thanks for the guidance!
