objective c - How to set default value in iOS Mantle model subclass -

- 

@interface entity ()   @property (assign) int searchtotalpagesall;   @property (assign) int searchtotalpagesideas; @end   @implementation entity   + (nsdictionary *)jsonkeypathsbypropertykey { return @{          @"id": @"entity.id_entity",          @"name": @"entity.name",          @"coverage" : @"entity.coverage",          @"id_city": @"entity.id_city",          @"cityname":@"entity.city",          @"countryname":@"entity.country",          @"statename":@"entity.district",          @"countrycode": @"entity.countrycode",          @"keyword1": @"entity.key1",       ... etc

since mantle examples doesn't have init method, should initialize properties (searchtotalpagesall, searchtotalpagesideas) default values ? model has internal methods need , several other properties.

whether create mantle model json or otherwise, model initialised [-initwithdictionary:error:]. in model class, can add defaults values used initialise model:

- (instancetype)initwithdictionary:(nsdictionary *)dictionaryvalue error:(nserror *__autoreleasing *)error {     nsdictionary *defaults = @{         @"searchtotalpagesall" : @(10),         @"searchtotalpagesideas" : @(5)     };     dictionaryvalue = [defaults mtl_dictionarybyaddingentriesfromdictionary:dictionaryvalue];     return [super initwithdictionary:dictionaryvalue error:error]; }

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
