Хранение в Plist?

Question

Мне просто интересно, как можно хранить эти данные в plist с тем же выходом. Теперь я использую NSObject. Я храню их в отдельном словаре? но тогда как я могу их вызвать, чтобы заполнить массив tableData.

Exercises *exercise1 = [Exercises new]; 
exercise1.name = @"Barbell Rollouts"; 
exercise1.materials = @"30 min"; 
exercise1.imageFile = @"BarbellRollouts.jpg"; 
exercise1.sets = @"2"; 
exercise1.reps = @"10"; 
exercise1.instructions = @"Hello"; 
exercise1.status = @"Dynamic"; 

Exercises *exercise2 = [Exercises new]; 
exercise2.name = @"Barbell Trunk Rotation"; 
exercise2.materials = @"30 min"; 
exercise2.imageFile = @"BarbellTrunkRotation.jpg"; 
exercise2.sets = @"2"; 
exercise2.reps = @"10"; 
exercise2.instructions = @""; 
    exercise2.status = @"Dynamic"; 

Exercises *exercise3 = [Exercises new]; 
exercise3.name = @"Bent Knee Leg Raises"; 
exercise3.materials = @"30 min"; 
exercise3.imageFile = @"BentKneeLegRaises.jpg"; 
exercise3.sets = @"2"; 
exercise3.reps = @"10"; 
exercise3.instructions = @""; 
    exercise3.status = @"Dynamic"; 

Exercises *exercise4 = [Exercises new]; 
exercise4.name = @"Bicycle Manouver"; 
exercise4.materials = @"30 min"; 
exercise4.imageFile = @"BicycleManouver.jpg"; 
exercise4.sets = @"2"; 
exercise4.reps = @"10"; 
exercise4.instructions = @""; 
    exercise4.status = @"Dynamic"; 

Exercises *exercise5 = [Exercises new]; 
exercise5.name = @"Boat Pose"; 
exercise5.materials = @"30 min"; 
exercise5.imageFile = @"BoatPose.jpg"; 
exercise5.sets = @"2"; 
exercise5.reps = @"10"; 
exercise5.instructions = @""; 
    exercise5.status = @"Static"; 

Exercises *exercise6 = [Exercises new]; 
exercise6.name = @"Bosu Boat Pose"; 
exercise6.materials = @"30 min"; 
exercise6.imageFile = @"BosuBoatPose.jpg"; 
exercise6.sets = @"2"; 
exercise6.reps = @"10"; 
exercise6.instructions = @""; 
    exercise6.status = @"Static"; 


tableData = [NSArray arrayWithObjects:exercise1,exercise2,exercise3,exercise4,exercise5,exercise6,nil]; 

Answer 1

Вы должны реализовать NSCodingprotocol

В вашем заголовке:

@interface Exercise : NSObject <NSCoding> 
// Your public property list 
@end 

В файле реализации:

@interface Exercise() 
// Your private property list 
@end 

@implementation Exercise 

- (id)initWithCoder:(NSCoder *)decoder { 
    self = [super init]; 
    if (!self) { 
     return nil; 
    } 

    self.name = [decoder decodeObjectForKey:@"name"]; 
    self.sets = [decoder decodeIntegerForKey:@"sets"]; 
    // similar approach for other properties 

    return self; 
} 

- (void)encodeWithCoder:(NSCoder *)encoder { 
    [encoder encodeObject:self.name forKey:@"name"]; 
    [encoder encodeInteger:self.sets forKey:@"sets"]; 
    // similar approach for other properties 
} 
@end 

Теперь вы должны быть в состоянии использовать NSKeyedArchiver для сохранить в ваш plist и NSKeyedUnarchiver прочитать его обратно:

[NSKeyedArchiver archiveRootObject:exercise toFile:@"/path/to/file"]; 
[NSKeyedUnarchiver unarchiveObjectWithFile:@"/path/to/file"];
