Это мой первый пост, поэтому я приношу свои извинения, если я пропустил руководство или два. Не стесняйтесь звонить мне. В любом случае. В настоящее время я медленно пытаюсь научиться объективным c и iOS/xcode, и, как таковой, я занимаюсь тонны учебников. Я наткнулся на одного и работал над ним, но хотел попытаться бросить вызов себе и сделать некоторые хитрости. В конечном итоге это процесс обучения. Поэтому мой основной вопрос заключается в следующем:Заменить массив объектов NS с помощью plist
В объективе-C с использованием Xcode, как заменить пользовательский класс NSObjects на plist?
Вот фрагмент кода, который я пытаюсь выяснить, как заменить с PLIST, который имеет ту же информацию:
@implementation RecipeBookViewController {
NSArray *recipes;
}
@synthesize tableView = _tableView;

{
[super viewDidLoad];
// Initialize table data
// recipes = [NSArray arrayWithObjects:@"Egg Benedict", @"Mushroom Risotto", @"Full Breakfast", @"Hamburger", @"Ham and Egg Sandwich", @"Creme Brelee", @"White Chocolate Donut", @"Starbucks Coffee", @"Vegetable Curry", @"Instant Noodle with Egg", @"Noodle with BBQ Pork", @"Japanese Noodle with Pork", @"Green Tea", @"Thai Shrimp Cake", @"Angry Birds Cake", @"Ham and Cheese Panini", nil];

}
он также ссылающийся на заказ класса Recipe.h и Recipe.m с кодом следующим образом:
recipe.h
#import <Foundation/Foundation.h>
@interface Recipe : NSObject
@property (nonatomic, strong) NSString *name; // name of recipe
@property (nonatomic, strong) NSString *prepTime; // preparation time
@property (nonatomic, strong) NSString *imageFile; // image filename of recipe
@property (nonatomic, strong) NSArray *ingredients; // ingredients
@end
Recipe.m
#import "Recipe.h"
@implementation Recipe
@synthesize name;
@synthesize prepTime;
@synthesize imageFile;
@synthesize ingredients;
@end
Я честно не уверен, что даже это возможно сделать, однако я бы хотел, чтобы вся эта информация в plist была легко редактируемой, вместо того, чтобы иметь неуклюжий код непосредственно в одном из файлов .m , Любая помощь будет очень оценена!
Спасибо!
Это может помочь вам-> http://stackoverflow.com/questions/6569207/write-custom-object-to-plist-in-cocoa – Vizllx
Я не обязательно хочу читать/записывать данные на plist файл, я просто хочу заменить данные файлом plist. Это возможно? – spoons55
Я не уверен, что понимаю, что вы пытаетесь выполнить, переместив эти данные в plist. Где вы говорите об изменении этой информации? Не из приложения? Непосредственно с помощью редактора plist? – rdelmar
