objective-c - OC中的点号语法如果要调用方法，只能调用无参的方法吗？

Question

#import <Foundation/Foundation.h>
/**
 默认的范围是protected
 **/
@interface Animal :NSObject
{
    int age;
    NSString * name;
}
-(void)run:(int)speed;
@end

@implementation Animal
-(void)run:(int)speed{ 
    
    NSLog(@"我的速度是%d",speed);  
}
@end
int main(int argc, const char * argv[]) {
    
    Animal*  animal=[Animal  new];
    
    animal.run:44;
    
    return 0;
  
}

貌似调用一个有参的方法就错了。但是我记得好像可以调用无参的方法。是这样的吗？
