クラスメソッド内でselfを使う

Last updated at Posted at 2012-08-05

親クラスに書いておくだけで
[HogeHoge hogeWithDictionary];
[Poi hogeWithDictionary];
によって子のオブジェクトが作れます。

hoge.m
@interface Hoge : NSObject
+ (id)hogeWithDictionary:(NSDictionary *)dic;
@end

@interface HogeHoge : Hoge
@end

@interface Poi : Hoge
@end

@implementation Hoge
+ (id)hogeWithDictionary:(NSDictionary *)dic
{
    Hoge  *hoge = [[[[self class] alloc] init] autorelease];
    [hoge setUp:dic];
    
    return hoge;
}

- (void)setUp:(NSDictionary *)dic
{
    //処理
    NSLog(@"Hoge処理");
}
@end

@implementation HogeHoge
- (void)setUp:(NSDictionary *)dic
{
    [super setUp:dic];
    //処理
    NSLog(@"HogeHoge処理");
}
@end


@implementation Poi
- (void)setUp:(NSDictionary *)dic
{
    //処理
    NSLog(@"Poi処理");
}
@end
