用于在 Objective-C 中定义 kvc 评估器的宏

是否有任何宏可以帮助简化 Objective C 中 KVC 宏的创建？就目前情况而言，创建一个多可变的 KVC 兼容属性是非常乏味的，要定义一个属性，需要以下代码

//Code.h
@property (strong, nonatomic, readonly) NSArray *prevSearches;

//Code.m

@property (strong, nonatomic, readwrite) NSArray *prevSearches;

...

@synthesize prevSearches = _prevSearches;

- (void)prevSearches {
    return [_prevSearches copy];
}

- (void)setPrevSearches:(NSArray *)prevSearches {
    _prevSearches = [NSMutableArray arrayWithArray:prevSearches];
}

- (void)insertObject:(SavedSearch *)object inPrevSearchesAtIndex:(NSUInteger)index {
    [_prevSearches insertObject:object atIndex:index];
}

- (void)removeObjectFromPrevSearchesAtIndex:(NSUInteger)index {
    [_prevSearches removeObjectAtIndex:index];
}

定义一个属性需要 20 多行，我经常在一个特定的类中有几个属性......当然有更简单的方法吗？

Is there any macro to help simplify the creation of KVC macros in Objective C? As it stands in order to create a to-many mutable KVC compliant property is extremely tedious, to define a single property it takes the following

//Code.h
@property (strong, nonatomic, readonly) NSArray *prevSearches;

//Code.m

@property (strong, nonatomic, readwrite) NSArray *prevSearches;

...

@synthesize prevSearches = _prevSearches;

- (void)prevSearches {
    return [_prevSearches copy];
}

- (void)setPrevSearches:(NSArray *)prevSearches {
    _prevSearches = [NSMutableArray arrayWithArray:prevSearches];
}

- (void)insertObject:(SavedSearch *)object inPrevSearchesAtIndex:(NSUInteger)index {
    [_prevSearches insertObject:object atIndex:index];
}

- (void)removeObjectFromPrevSearchesAtIndex:(NSUInteger)index {
    [_prevSearches removeObjectAtIndex:index];
}

That's over 20 lines to define a single property, I often have several in a particular class... Surely there's an easier way?
