搞不懂 objection

[0nlyy0u]

比如：
我现在有个Dog类

@implementation Dog

- (instancetype)initWithName:(NSString *)name {
    if (self = [super init]) {
        _name = name;
    }
    return self;
}

然后在ViewController里

@interface ViewController ()

@property (strong, nonatomic) Dog *dog;

@end

@implementation ViewController

objection_requires(@"dog");

objection_initializer(initWithName:, @"Chuck")

- (void)viewDidLoad {
    [super viewDidLoad];

    JSObjectionInjector *injector = [JSObjection createInjector];
    [injector injectDependencies:self];

    NSLog(@"%@", self.dog);
    NSLog(@"%@", self.dog.name);
}

objection_requires(@"dog")是调用的dog的init方法。我现在想调用dog的initWithName。发觉objection_initializer(initWithName:, @"Chuck")根本没起作用呢。
