ios - CountryPicker UIPickerView calls subclassed method instead of its own -


so have problem using 2 uipickerview controls in 1 viewcontroller. using countrypicker found here https://github.com/nicklockwood/countrypicker show nice country picker user can select or hers country, , country code or hers phone number. want limit number of countries in 1 of pickers , show countries in other picker. when show 2 pickers, seems 1 has countrypicker type using overriden method -countriesofoperation customcountrypicker class.

i have tried storyboard , programatically init 2 pickers without success. can see i've tried remove first picker before showing second 1 , vice versa, won't fix it.

what reason setting *countryselectionpickerview countrypicker, still uses overriden method customcountrypicker? object of type countrypicker, still shows short countries list.

customcountrypicker.h

#import <countrypicker/countrypicker.h>  @interface customcountrypicker : countrypicker  /// returns dictionary of country names, keyed country code. +(nsdictionary<nsstring *, nsstring *> *)countrynamesbycode;  @end

customcountrypicker.m

#import "customcountrypicker.h"  @implementation customcountrypicker  -(instancetype)initwithframe:(cgrect)frame {     return [super initwithframe:frame]; }  +(nsdictionary *)countriesofoperation {     nsdictionary *countries = @{ @"dk": @"denmark",                                  @"de": @"germany",                                  @"gb": @"great britain",                                  @"fr": @"france",                                  @"no": @"norway",                                  @"ch": @"switzerland"                                 };     return countries; }  +(nsdictionary *)countrynamesbycode {     nsdictionary *countries = [self countriesofoperation];     static nsdictionary *_countrynamesbycode = nil;     if (!_countrynamesbycode)     {         nsmutabledictionary *namesbycode = [nsmutabledictionary dictionary];         (nsstring *code in [nslocale isocountrycodes])         {             if([countries valueforkey:code]) {                 nsstring *countryname = [[nslocale currentlocale] displaynameforkey:nslocalecountrycode value:code];                  //workaround simulator bug                 if (!countryname)                 {                     countryname = [[nslocale localewithlocaleidentifier:@"en_us"] displaynameforkey:nslocalecountrycode value:code];                 }                 countryname = [countryname stringbyappendingstring:@" xxx"];                 namesbycode[code] = countryname ?: code;             }         }         _countrynamesbycode = [namesbycode copy];     }     return _countrynamesbycode; }

this because library using static variables both custom subclass , original countrypicker share data. can remove static keyword _countrynames, _countrycodes, _countrynamesbycode , _countrycodesbyname , should work.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
