OC中的点号语法如果要调用方法，只能调用无参的方法吗？
#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？

你问的是怎么调用无参数的方法吧？
刚被
Masonry
的封装震撼到，链式调用一气呵成，优雅！完美！
@interface TestObject : NSObject
@property (nonatomic, readonly) dispatch_block_t function;
@end
@implementation TestObject
- (dispatch_block_t)function
{
return ^{
NSLog(@"function run !");
};
}
@end
TestObject * obj = [[TestObject alloc] init];
obj.function();
